Background: Paraoxonase-1 (PON1) is one of the most important enzymes for removal of the free radicals, and the main protective factor for lipoproteins against oxidative agents. The purpose of this study was to investigate the effects of eight weeks’ rope training on paraoxonase-1 enzyme, insulin resistance and lipid profiles in inactive overweight and obese girls.
Methods: This quasi-experimental study was conducted in Iranian Azarbaijan Shahid Madani University of Tabriz, from November 2016 to January 2017. In this study, 20 healthy overweight and obese in-active girls (20-25 Yr) volunteered and randomly assigned into exercise (n=10) and control (n=10) groups. Exercise protocol was rope training was 8 week for 4 day per week in 45 minute per day. Some anthropometric indexes of subjects were measured before and after exercise. A fasting blood sample was collected as pre-test and post-test, followed by 48 hours of physical inactivity to measure serum levels of PON1 enzyme, Insulin, lipid profiles and other blood variables. Analysis of the data was performed by paired and independent samples t-tests by using the SPSS software, version 20 (IBM, Armonk, NY, USA). The criterion of statistical significance was set as P<0.05.
Results: The paired samples t-test results showed that after exercise intervention, in exercise group, the values of all variables (except low-density lipoprotein) were significantly changed. Also, to compare with control group, the values of PON1 enzyme (P=0.024) and maximum oxygen consumption (P=0.006) significantly increased and insulin resistance index (P=0.028), triglyceride (P=0.046) and body fat percent (P=0.001) were significantly decreased (P<0.05).
Conclusion: The results of this study showed that performing rope training for 8 weeks induced positive changes in paraoxonase-1 enzyme, insulin resistance index, maximum oxygen consumption and some lipid and anthropometric indices in overweight and obese young girls. Therefore, according to these results, rope training, as an aerobic activity it can be useful for all people especially in overweight and obese to control blood fats, body composition and prevent diseases due to obesity such as cardiovascular disease. 

Cutaneous leishmaniasis (CL) is an endemic parasitic disease of major health impact in many parts of the world and is caused by several species of the protozoan parasite Leishmania. Antimonial compounds (i.e glucantime and pentostam) are the first-line treatment for cutaneous leishmaniasis with emerging drug resistance as a problem. The control of Leishmania is further complicated by the emergence of drug-resistant parasites. In the clinical settings, resistance to SbV containing drugs is now well established and it was found to occur in South America, Europe, the Middle East and most notably in India. Clinical resistance to organic pentavalent antimonials, in the form of sodium stibogluconate (pentostam) or N-methylglucamine antimoniate (glucantime), has long been recognized. However, it is unknown whether the clinical failure of chemotherapy is attributable to the development of drug resistance mechanisms in the parasite or to a variety of host factors that might also contribute to low drug response. Reported rate of drug-resistance to antimonial compounds in Iran varies from 9.4% to 94.2% and there is not any comprehensive study on this issue. Indeed, in the endemic region treatment with SbV fails in more cases; thus, in general patients infected with resistant parasites are unresponsive although exceptions have been reported. This article aims to review the mechanisms of drug resistance to these compounds. The main resistance factors include genetical, enzymatic, intracellular (such as apoptosis and cytoskeleton changes) and resistance proteins. Also, mechanisms related to drug transport and intracellular activation are discussed. Various methods of drug resistance detection such as culture and molecular methods (i.e polymerase chain reaction) are reviewed. Although the exact mechanism of action glucantime is not clear, it seems that protein and gene factors involved in cellular drug entry are the main causes of drug resistance. Cross-sectional studies on meglumine antimoniate resistance in endemic areas of cutaneous leishmaniasis in Iran are highly recommended. Also, studies for evaluation of alternatives therapies for antimonial resistant cases are required.   

Background: 2-phenylethanol is a colorless and aromatic compound with antimicrobial effects which is used extensively in perfumes and cosmetics, as well as in the food industry. Chronic vulvovaginal candidiasis is a vulvovaginal inflammation which is caused by Candida spp. Resistance to clotrimazole which is one of the most common drugs in the treatment of this disease was reported in many patients. In order to improve the treatment, the effect of 2-phenyl ethanol was investigated in combination with clotrimazole on Candida species isolated from chronic vulvovaginal candidiasis.
Methods: This interventional study was performed in Iran University of Medical Sciences from February, 2016 until December, 2016 on Candida species isolated from women with chronic candidial vulvovaginitis who had been referred to Lolagar Hospital of Tehran. All specimens were examined by direct microscopy, culturing on Candida CHROMagar medium (to primary identification), sabouraud dextrose agar medium) to preservation the isolates) and determining the internal transcribed spacer (ITS) sequence (in order to final determination of Candida species). Then clotrimazole and 2-phenyl ethanol alone and in combination, was examined on isolated species, according to Clinical and Laboratory Standards Institute (CLSI) M27-A3 protocol (micro-broth dilution method). Finally, findings were analyzed.
Results: From 40 detected strains of Candida species in this study, 95% were Candida albicans and 5% were Candida africana. The mean minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) of clotrimazole were 24.73±28.87 µg/ml and 30.18±33.004 µg/ml, respectively and the mean MIC and MFC of 2-phenylethanol were 2580±932.38 µg/ml and 3200±1403.29 µg/ml, respectively. The MIC50 and MIC90 of clotrimazole were 16 and 64 µg/ml, respectively. The MIC50 and MIC90 of 2-phenylethanol were both 3200 µg/ml. Most of the isolates were resistant to clotrimazole (82.5%). In combination test, the mean MIC of 2-phenylethanol and clotrimazole alone were 3200±0 µg/ml and 56±40.16 µg/ml, respectively. The fractional inhibitory concentration index (FICI) range was 0.14-0.37. Also, there was a significant difference between clotrimazole MIC values alone and in combination (P= 0.021).
Conclusion: The synergistic effect was observed in combination of clotrimazole and 2-phenylethanol.

Background: Pseudomonas aeruginosa is an opportunistic pathogen and one of the important factors of hospital infection. It causes many issues such as urinary tract infections, respiratory infection in cystic fibrosis patients, and wound infection in burn patients, septicemia and meningitis. Antibiotic resistance through various mechanisms is one of the challenges for the treatment of pseudomonad-caused infections. According to the inherent and acquired capacity of this bacterium in creating resistance against the antimicrobial factors, it is very important to identify a pattern for its antibiotic resistance. The aim of this study was to deliberate the frequency of pattern antibiotic resistance of pseudomonas aeruginosa strains.
Methods: In this cross-sectional study, 200 pseudomonas aeruginosa isolations (from 86 males and 114 females) were collected from different samples such as urine, blood, wound, catheter and other samples from teaching hospitals in Zahedan City during nine-month period in 2017. After conducting biochemical tests and confirming bacterium type, based on Clinical Laboratory Standards Institute (CLSI), the antibiotic resistance of strains for 10 antibiotics was determined using disk diffusion method. In addition, the minimum inhibitory concentration of three antibiotics such as imipenem, piperacillin/tazobactam and ceftazidime were determined through E-test. The Chi-square test was used for statistical analysis through the SPSS software, version 16 (IBM SPSS, Armonk, NY, USA).
Results: Out of 200 pseudomonas aeruginosa isolations (from 86 males and 114 females), the maximum resistance was related to ciprofloxacin (37%) and gentamicin (28.5%). The minimum resistance was related to piperacillin/tazobactam (6.5%) and ceftazidime (6%). The highest separated strain was from urine sample (54%), blood sample (23.5%) and wound sample (10.5%). Additionally all strains were sensitive to colistin. In this study, the percentage of multidrug-resistance (MDR) and extensively drug-resistant (XDR) strains were investigated, which were 13% and 5.5%, respectively.
Conclusion: In this study, pseudomonas aeruginosa isolates had the lowest resistance to ceftazidime which this antibiotic could be the main treatment option. The high prevalence of MDR strains is a serious warning.

Background: Escherichia coli (E. coli) is one of the most important infectious agents in patients undergoing prostate biopsy. It belongs to a large family of gram-negative rods, Enterobacteriaceae. This family includes members of the normal flora of the intestine that are only occasionally pathogenic. Recent considerations of rectal colonization with fluoroquinolone-resistant E. coli shows the need to change strategy of treatment of infection in patients undergoing prostate biopsy. Therefore, the purpose of this study was to determine molecular typing of fluoroquinolone resistant (FQR) E. coli rectal isolates and associated infections in patients undergoing prostate biopsy.
Methods: In this prospective cohort study, rectal swabs were collected from 158 male patients before prostate biopsy at the Urology Research Center of Sina Hospital, Tehran, Iran, from March 2015 to February 2016. The FQR organisms were isolated using selective media, and antibiotic susceptibility pattern was determined for following antibiotics, ampicillin, levofloxacin, cotrimoxazole, amoxicillin-clavulanate, cefazolin, ceftazidime, cefepime, gentamicin, piperacillin-tazobactam, nitrofurantoin, amikacin, fosfomycin, imipenem. In general, phylogenetic background, prevalence of E. coli sequence type 131 (ST131) and its subclones (H30 and H30-Rx ST131) were compared in two groups of FQR E. coli rectal colonization and clinical isolates.
Results: In total, 73 patients had a positive rectal culture for FQR gram-negative bacteria, the most prevalent isolate of which was E. coli. Phylogenetic group B2 was most predominant, followed by A, E, C and D, B1 and F. The antibiotic susceptibility patterns for the FQR organisms showed high levels of resistance to ampicillin and trimethoprim-sulfamethoxazole, while the resistance to amikacin, fosfomycin and imipenem remained very low. In general, antibiotic resistance to several antibiotic was mainly detected in group B2 and with ST131 genotype. Despite the increase in infections among patients colonized with strains of E. coli ST131, its frequency was almost statistically significant between colonized and infected groups.
Conclusion: The ST131 pathogen has a high prevalence in rectal colonization and post prostate biopsy infections, which showed widespread resistance to common antibiotics.

Background: Campylobacter genus is considered some of the most important agents of bacterial gastroenteritis worldwide. Campylobacter coli (C. coli) is accounted to at least 25% of all Campylobacter related diarrheal diseases moreover, C. coli infections can result in severe complications, such as bacteremia, sepsis, meningitis and spontaneous abortion. Finally, there is evidence that the frequency of antimicrobial resistance is higher in C. coli, when compared to C. jejuni. There is no data regarding the frequency and antibiotic resistance profile of C. jejuni isolated from human gastroenteritis samples. The present study aimed to determine the frequency and antibiotic resistance patterns of Campylobacter coli isolated from infectious diarrhea samples.
Methods: In a descriptive cross-sectional study, 200 infectious diarrhea samples collected in Arak University of Medical Sciences Hospitals, Markazi Province, Iran, from May to November 2015 were subjected to the study. In order to identify C. coli modified Gram stain, modified charcoal-cefoperazone-deoxycholate agar (mCCDA) and Brucella agar media with filter and CeuE gene polymerase chain reaction (PCR) were accomplished. Antibiotic resistance against tetracycline, erythromycin, ciprofloxacin, ampicillin and gentamicin was evaluated phenotypically and genotypically.
Results: In total, out of 200 modified gram stained samples, 2 cases (1%) of C. coli were identified. Cultivating methods using mCCDA medium found 2 isolates (1%), 3 isolates (1.5%) were grown on Brucella agar with filter and 5 cases (2.5%) were determined as C. coli using PCR assay. Antibiotic resistance was observed in 5 cases against tetracycline, erythromycin and ciprofloxacin (100%), in 4 cases against ampicillin (80%), in 2 cases against gentamicin (40%), in 5 cases with CmeB, 23srRNA mutation in, qnrS, tet (o) (100%), in 4 cases with gyrA4 (80%), in 3 cases with gyrA5 (60%), in 5 cases with gyrA6 (100%), in 4 cases with Oxa61 (60%) and in 1 case with aphA-3-1 (20%).
Conclusion: In this present study C. coli with low prevalence and entire resistance to ciprofloxacin and erythromycin which are the first line antibiotic for the treatment of campylobacter gastroenteritis is introduced as a causative agent of gastroenteritis in patients at central part of Iran.

Background: Metronidazole resistant clostridium difficile is one of significant pathogens in Iran. It is one of the WHO-declared microbial resistance emergencies. Prevalence of metronidazole resistant clostridium difficile is rising. The aim of this study was to detect prevalence of metronidazole-resistant clostridium difficile using meta-analysis in Iran.
Methods: This study was conducted as a meta-analysis. Articles and derivatives were reviewed by two researchers. Initially, each of the researchers searched the databases separately and used all available Persian and English articles in Kurdistan University of Medical Sciences, Iran, from October 2017 to February 2018. Persian databases (including Magiran, Irandoc, Barakat and SID) and international databases (including PubMed, Sciencedirect, and Scopus) were searched during this period (2007-2016) with a combination of phrases and keywords. The list of references to these studies has also been evaluated and relevant articles have been included in the study. First, all the articles were extracted and then duplicated articles were deleted using the EndNote software, version X6 (Thomson Reuters™, New York, NY, USA) through the search for electronic banks. Such that the high heterogeneity (50% Results: From the search of medical databases at first, 68 articles were selected. In total, 19 remaining studies entered the meta-analysis phase. In this study, the overall prevalence of clostridium difficile is 32.57% (CI95%: 21.86-44.30); in 2016 it was 55.25% (CI95%: 50.22-60.19) and in 2009 was14.26% (CI95%: 12.32-16.37). The heterogeneity was estimated to be 98.7% (CI95%: 98.5-98.8).
Conclusion: Based on the results of this study, the prevalence of metronidazole resistant clostridium difficile in Iran is high and increasing.

Background: Health care associated infections (HAIs) are a class of infections that infect patients during hospital admissions and receive medical services. These infections occurs within 48 to 72 hours of admission and up to 6 weeks after discharge. Surveillance of device-associated infections (DAIs) in intensive care units (ICUs) is substantial in planning healthcare strategies. This study was conducted to determine the device-associated infections' burden and antimicrobial resistance patterns.
Methods: In this descriptive-analytic study, three common device-associated infections included central line-associated bloodstream infection (CLA-BSI), ventilator associated pneumonia (VAP), and catheter-associated urinary tract infection (CA-UTI), were assessed in intensive care units of Besat Hospital in Hamedan from April 2017 to April 2018. In order to determine the incidence of device-associated infections, the number of device-associated infection cases was calculated during the study period and divided into the number of device-days used. The device-days included all days of exposure to that device (vascular catheter, endotracheal tube (ventilator), or urinary catheter) in all patients in the study population.
Results: Out of 1806 intensive care unit admitted cases, 168 patients (9.3%) were device-associated infection with distribution of 92 cases (55%) of ventilator-associated pneumonia (VAP), 56 cases (34%) of catheter-associated urinary tract infection (CA-UTI) and 20 cases (11%) of central line-associated bloodstream infection (CL-BSI). The incidence of VAP, CA-UTI and CL-BSI was 44.7, 17.5, and 21.61 days, respectively. The most organisms were Acinetobacter (27.4%), Klebsiella (18.3%), Escherichia coli (E. coli) (15.4%). Vancomycin-resistant enterococcus (VRE) was 75%. Acinetobacter resistance to colistin and carbapenem was 16.8%. About half of Pseudomonas isolates were resistant to meropenem.
Conclusion: According to the present findings of this study, a high incidence of device-associated infections and resistant organisms in our intensive care units were documented, which represents a need to reinforce the preventive and control programs. Various results in different studies can be due to differences in the level of health care in different centers and countries.

Background: TRX training is a new training method that has beneficial effects on improving balance and strength. However, the role of these types of training on the factors associated with function and mitochondrial biogenesis is not understood. Therefore, the purpose of present study was to determine the effect of eight weeks of TRX training on serum levels of Peroxisome proliferator-activated receptor-γ coactivator 1α (PGC-1α) and citrate synthase in overweight women.
Methods: All subjects gave written informed consent after a detailed description of the study procedures. The protocol of this study was approved by the Research Ethics Committee of Sport Sciences Research Institute (SSRI) in Iran. The present study was experimental and was conducted in Shahid Ghaffari women's club in Tehran under the supervision of Alzahra University from May 2018 to January 2019. For this purpose, 30 overweight women after primary alignment on basis of body mass index (25-30 kg/m2) were divided into two groups: control (n=14) and TRX training (n=16). The TRX training protocol was performed for eight weeks and 3 sessions per week, which included 6 main movements (squat, rear deltoid row, biceps curl, chest press, low row, rotational ward) that lasted 60 minutes per session. According to consideration the physical condition of each person, the subjects were free to modulate the exercise intensity by changing the body inclinations. Each exercise provided 4 sets of 12 repetitions separated by one-minute rest. Blood sampling was performed in two stages of pre-test and 48 hours after the last session of the exercise in overnight fasting state. After collection of serum samples, enzyme-linked immunosorbent assay (ELISA) method was used to measure serum levels of PGC-1α and citrate synthase.
Results: The results showed that TRX training caused no significant change in the body weight and body mass index compared to the control group. In addition, TRX training increased significantly the serum levels of PGC-1α and citrate synthase compared to the pre-test and the control group.
Conclusion: The findings of the present study indicated that eight weeks of TRX training could increase serum levels of PGC-1α and citrate synthase in overweight women.

Background: Obesity is associated with chronic inflammation in obese subjects, which leads to an increase of inflammatory cytokines. This study aimed to evaluate the effect of different intensity circuit resistance training on levels of interleukin 1 beta and interleukin-10 in obese men.
Methods: In a semi-experimental trial during May to August 2020, 44 obese men from Tehran city were selected and randomly divided into 4 groups including 1) control (n=11), 2) low-intensity circuit resistance training (n=11), 3) Moderate intensity circuit resistance training (n=11) and 4) High-intensity circuit resistance training (n=11). Resistance training was performed in different intensities including1) High-intensity circuit resistance training: three sets of 10 repetitions with 80% 1RM 2) Moderate intensity circuit resistance: three sets of 13 repetitions with 60% 1RM and 3) low-intensity circuit resistance training: three sets of 20 repetitions with 40% 1RM, three sessions per week for 12 weeks. Also, the control group had their daily life during the 12-week research period and were prohibited from participating in regular exercise. Serum interleukin-1 beta (IL-1β) and interleukin-10 (IL-10) levels were measured using an ELISA kit. Data were analyzed with covariance analysis at P<0.05.
Results: Twelve weeks of low, Moderate and high intensity circuit resistance training significantly decreased IL-1β levels (P=0.001) and increased IL-10 levels in obese men (P=0.001). The decrease of IL-1β was significant in the high-intensity training group compared to low intensity (P=0.009) and moderate-intensity training groups (P=0.046). Also, the increase in IL-10 levels was significant in the high-intensity training group compared to the low-intensity (P=0.002) and the moderate intensity training group compared to the low intensity training group (P=0.004).

Conclusion: According to our findings, resistance training has a positive effect on inflammatory and anti-inflammatory factors in obese men, and high-intensity circular resistance training had more benefits.

Background: Urinary tract infections are among the most common diseases in different communities and occur in all age groups. Failure to diagnose the disease correctly and promptly can cause complications such as damage to the urinary tract and kidney parenchyma, increased blood pressure, uremia. Also, in pregnant female patients It may lead to premature birth and even abortion. Therefore, correct and timely administration of antibiotics is very important in the treatment of patients. This study aimed to compare the results of antibiogram testing of patients with suspected urinary tract infections by both rapid and classical methods.
Methods: This cross-sectional study was performed from the beginning of March to the beginning of September 2019, on patients with urinary tract infection Who had been referred to Sina Hospital of Hamedan, Iran. Urine samples were collected 20 cc from patients. The test was performed directly at the same time with urine culture to determine antibiotic susceptibility. The agreement between the two methods was considered as a huge error, major error and minor error. Finally, the data were statistically analyzed with SPSS software version 16.

Background: Considering the frequency of MRSA strains in hospitals and medical centers as well as in different communities, it seems necessary and important to observe the use of appropriate drugs in order to reduce antibiotic resistance and reduce the economic costs of treatment. This study aimed to investigate the antibiotic resistance pattern of MRSA isolated from blood and wound samples of patients. The study patients were hospitalized in different departments in a number of Tehran University of Medical Sciences hospitals.
Methods: In this descriptive cross-sectional study from September 2021 to February 2022, the blood and wound samples of the patients were collected and referred to laboratory. Staphylococcus aureus had identified by phenotypic and biotypic tests. MRSA isolates were screened by showing resistance to Cefoxitin by disc diffusion method and finally confirmed by examining the mecA gene by PCR. The microbial resistance pattern of MRSA was also measured by disk diffusion method and resistance to Vancomycin was confirmed by E.test.

Results: 41 isolates from 87 Staphylococcus aureus samples were confirmed as MRSA by present the mecA gene. The mecA gene was detected in all MRSA by PCR method. The antibiotic resistance pattern showed the highest sensitivity to Vancomycin and Linezolid with 100% sensitivity and the highest resistance to three antibiotics Erythromycin, Ceftriaxone and Cloxacillin with 97.57%by disk diffusion method. The most MRSA strains were isolated from the ICU department with 13 cases and the least MRSA strains were isolated from the two NICU and pediatric departments with one case.The majority of the population infected with MRSA belonged to the age group of 40-65 years. Conclusion: The prevalence of microbial resistance with high dispersion was obtained among MRSA strains isolated from clinical samples; which indicates a significant increase in resistant strains and requires a quick and timely diagnosis to prescribe the appropriate antibiotic.

Background: Angiogenesis is a physiological process leading to capillary density enhancement and better blood distribution in skeletal muscles, which triggers in response to physical training. The present study aimed to investigate the changes in physiological factors involved in angiogenesis in response to circuit or traditional resistance training.
Methods: Thirty-six healthy sedentary students who were studying at Shahid Rajaee Teacher Training University of Tehran (age: 22.1±2.3 years; height: 172.7±5.1 cm) volunteered to participate in the study (from October 2021 to February 2022). Following a pre-test to evaluate one repetition maximum (1RM) of selected movements (Leg Press, Leg Curl, Leg Extension, Bench Pull, Seated Row, Biceps Curl), subjects randomly divided into Circuit Resistance training (CRT) (training protocol included 4 circles/3 times a week/8 weeks circuit performance/50-55% 1 Repetition Maximum (1RM), n=12), Traditional resistance training (RT) (training protocol included 8 repetition/3 set/3 time per week/8 weeks of same movements with 75% 1RM followed by 2 minutes break to rest between the sets; n=12) and the control group without any regular training (n=12). We assessed the level of Vascular Endothelial Growth Factor (VEGF), plasma level of growth hormone (GH), and Basic Fibroblast Growth Factor (BFGF) to the mentioned training methods. Data were evaluated by utilizing SPSS version 14.

Results: Present findings showed that CRT and RT protocols resulted in significant increases in post-test compared to pre-test in VEGF (P=0.00), GH (P=0.04), and BFGF (P=0.00). In addition, the magnitude of changes in VEGF and GH were significantly greater than the magnitude of changes in control group in post-test (P=0.03, and 0.001, respectively). Furthermore, there was a strong correlation between absolute values of GH and VEGF (r=0.74 and r=0.71) following CRT (P=0.01) and RT (P=0.02). Conclusion: This study demonstrated that CRT and RT might enhance angiogenesis through an increase in VEGF, bFGF and GH, leading to better blood distribution in muscles.

Background: Salmonella enterica subspecies enterica serotype Enteritidis (S. Enteritidis) is one of the leading causes of food-borne infections associated with the consumption of contaminated food products of animal origin in humans. gastroenteritis due to Salmonella is usually a self-limiting disease and does not require antibiotic therapy. However, antibiotic treatment for salmonellosis may be lifesaving for patients with severe infections.The objective of the present study was to examine antimicrobial resistance and determine its genetic basis in recently isolated S.Enteritidis strains.
Methods: During this study, in a cross-sectional descriptive study, 44 isolates of Salmonella enteritidis from human sources were investigated between September 2021 and September 2022.. After identification of the isolates using phenotypic and molecular methods by Multoplex-PCR, antibiotic resistance testing was performed according CLSI 2023. The strains were examined for the presence of qnrA,qnrB,qnrS and gyrA resistance genes by PCR.

Results:  In a cross-sectional descriptive study, 44 isolates of Salmonella Enteritidis from human sources were investigated between September 2022 and September 2023. 100% of the strains were sensitive to imipenem and meropenem, and the sensitivity to the antibiotics ceftriaxone, ceftazidime, and cefotaxime were 93.2%, 90.9%, and 94.1%, respectively. 81.8% of isolates were sensitive to cotrimoxazole, sensitivity to ampicillin was 84.1%. Only 9.1% of isolates were sensitive to ciprofloxacin. Based on MIC results, 16 isolates had MIC between 0.002 and 0.064 and were placed in the sensitive area. 28 isolates had MIC between 0.125 and 0.5 and were placed in the area of reduced sensitivity. None of the strains resistant to disk diffusion method were resistant to MIC method. qnrA, qnrB and qnrS genes were not observed among ciprofloxacin resistant strains. All nalidixic acid resistant strains had gyrA gene. Conclusion: In general, it was shown in this study that the resistance to the fluoroquinolone family is increasing among Salmonella Enteritidis isolates. On the other hand, we see a decrease in the sensitivity and prevalence of strains resistant to broad-spectrum cephalosporins among serovar Enteritidis, which is the drug of choice for extraintestinal infections.
