Abstract
Drug therapy and prophylaxy in infectious diseases, from hygienic and economical point of view, are very important. Infections caused by pseudomonas aeroginosa were particularly severe, with high mortality rates. In the recent years pseudomonas aeroginosa continued to cause the most severe, life-thereating infections in burned patients, in spite of the introduction of a wide variety of antibiotics advised specifically for their anti pseudomonal activity. The aim of this study, in which many cases of ps.aeroginosa infections are assessed is to identify the drug resistance of this bacteria to penicillines, cephalosporins and aminoglycosides by antibiotic sensitivity test (disk ager diffusion). Results as percent of resistance to each antibiotic were 89% to carbenicillin, 55% to piperacillin, 89% to mezlocillin, 89.5% to ticarcillin+clavulonic acid, 85% to ceftriaxone, 95% to tobramycin, 5% of all isolates were not sensitive to any antibiotics.

Abstract
Methicillin resistant staphylococcus aureus (MRSA) is a predominantly nosocomial pathogen which its prevalence has increased worldwide over the past three decades.
Materials and Methods: This is a descriptive cross-sectional study. The following study is designed for determination of prevalence of MRSA infection through measurement of MICs of S. aureus isolates in Imam Khomeini Hospital (a teaching hospital) from November 2001 to January 2003. A total number of 402 specimens were isolated and specified as S. aureus by Imam Khomeini microbiology lab. Demographic and clinical data and results of MIC were analysed by Epilnfo 6 software.
Results: During the study, staphylococcus aureus was isolated from 402 patients that 187 (46.5%) of isolates were MRSA and 215 (53.5%) were MSSA. Of 402 patients, 254 (63.2%) were male and 148 (36.8%) were female. The difference of the prevalence of MRSA between males and females was not statistically significant (p= 0.09). The difference in mean age in MRSA and MSSA groups was not statistically significant (p= 0.55). In the age group of < 1 month, the prevalence of MRSA infection was significantly higher than other groups (P= 0.01).
Conclusion: In this study, the prevalence of MRSA infection was increased, statistically significant in the presence of such factors as sepsis, longer duration of hospitalization, hospital- acquired infection, history of invasive procedure, history of antimicrobials used in the past 3 months and type of administered antimicrobial (s), history of hospitalization in the preceding year, certain underlying diseases, type of admission ward, type of infection, type of specimen and type of administered antimicrobials for treatment. Surprisingly, the prevalence of MRSA infection in IV drug user group was low that was statistically significant (p< 0.0001). In this study, there was no statistically significant difference in outcome between MRSA infected and MSSA infected patients. Based on results of this study, prevalence of infections due MRSA in this hospital are high, therefore addition to diagnosis of risk factors of MRSA infections, application of standard infection control practices should be done for limitation of these infections.

Abstract
Background: Staphylococcus aureus (SA (is an important cause of nosocomial and community-acquired infections. The emergence of antibiotic resistance, especially in methicillin-resistant SA (MRSA) strains, has caused difficulties in treatment of such infections. The determination of antibiotic resistance patterns, particularly domestic patterns of Iran, is essential for appropriate treatment of MRSA infections and proper infection control measures in our country.
Methods: The antibiotic resistance of 338 SA isolates from various clinical specimens was determined by disk agar diffusion (DAD), minimum inhibitory concentration (MIC) and polymerase chain reaction (PCR) methods.
Results: Using the DAD method, 47% (160/338) of the SA isolates were resistant to oxacillin, and only 6% (20/338) were resistant to vancomycin. By PCR, 48% (162/338) of the isolates had the mecA gene. The MIC of oxacillin in 93% of isolates was higher than 256µg/mL. The MRSA isolates, showed a high resistant to gentamicin (40.5%), erythromycin (40%), and ciprofloxacin (38%). However, only a few of the SA isolates showed a high resistance to vancomycin (5%) or erythromycin (3.5%).
Conclusion: The results of this study can provide guidance for physicians toward a more appropriate treatment of SA infections in Iran, thereby preventing the emergence of further antibiotic resistance among SA. Our results also revealed the need for further investigations using a higher number of specimens representing a wider variety of locations to determine the antibiotic resistance patterns in our state more precisely.
