Abstract
Background and Objectives: Kala azar is a parasitic disease which belongs to the category of metazoonoses (a communicable disease which requires at least to an invertebrate host), In Iran canines are major reservoir for it and most of patients are 6 months to 2 years old. The aim of this study was evaluation of the clinical and epidemiologic aspects of visceral leishmaniasis in patients visiting the Children Medical Center over the 12 past years.
Methods: This study used the hospital records of a case series of 106 kala azar patients hospitalized in the Children's Medical Center between 1991 and 2001. We extracted and analyzed data on geographical location, background factors, clinical and laboratory findings, response to treatment and Glucantimeâ side effects.
Results: The greatest number of cases was seen in 1992 and the smallest number in 1993 and 2003 the number of cases peaked in the spring. Most patients referred to the Center are aged 1 to 4 years, and there is a strong preponderance of males (82.1% vs 17.9%). The majority of these children came from families in which the breadwinner was a peasants or a laborer. Common laboratory findings included anemia, rising ESR titers and thrombocytopenia. The most striking clinical signs and symptoms were fever, splenomegaly and hepatomegaly. Eighty-three percent of the patients had shown clinical improvement, 1.9% had died and 15.1% had relapsed. Moreover, in 52.8% of cases, the disease was treated successfully with within 2 weeks the incidence of Glucantimâ side effects was low. The cities of Khorramabad, Karaj and Saveh had produced the greatest numbers of cases.
Conclusions: Compared to other studies, our case series showed a higher proportion of male patients and a somewhat different clinical and laboratory profile. However, the most important achievement of this study was identification of major endemic foci in Ardabil province, northwestern parts of Ghom province, Khorramabad, and regions located south of the Alborz Mountains (e.g. Saveh

Abstract
Background & Objectives: Rabies is one of the oldest and most lethal zoonoses in the world. Cases have been reported from most provinces of Iran, involving both domestic and wild animals. This study aimed to define the epidemiology of rabies in human and animal populations in the western province of Ilam and was conducted in all of the 7 cities of the province.
Methods: In this descriptive study we recorded data on the number of the persons bitten by animals, geographical location, age category, occupation and professional relationships, pre-exposure prophylaxis, treatment for rabies, conditions of the injured organs, and the mortality rate. Data were analyzed using the SPSS software package.
Results: There were 4 human deaths from rabies in this province (2 men and 2 women) three of these cases had been bitten by dogs and the remaining one by a cat. The mean age of these people was 25.2 years (SD=15.3y). A total of 2431 people had been bitten by animals over the preceding 10 years. Most such injuries happened in the 10-29y age group and the frequency was greater for males (P<0.01). About 64% of all cases had been reported from rural areas, and the greatest number of injuries occurred in winter and spring. The most common sites of injury were hands and feet (88.5%), trunk and the cervical region (9.3%) and head/ face (2.2%).
Conclusion: The increasing number of stray dogs and the movement of dogs and wild animals into cities and villages are important factors in the transmission of rabies. More research needs to be done on the eco-epidemiology of the disease in different cities of Ilam.

Abstract
Background & Objectives: White spot, as one of the infectious viral diseases, has made severe losses in
shrimp ponds all over the world. Despite extensive efforts made to deal with
and control the disease, white spot continues to be a major health problem in
shrimp farms across Iran. In this work, the significance of the risk factors of
white spot disease epidemic occurred in shrimp ponds of Choubdeh farming site
in Khuzestan province of Iran is determined.
Methods: A cross sectional study was conducted from June 1, 2010, to
September 22, 2010 in 223 shrimp ponds of the site. Data was collected on 17
variables, thought to be associated with the occurrence and epidemic of white
spot, with the aid of the shrimp ponds owners and fisheries and veterinary
organizations. The occurrence of white spot disease in the farming site was
determined by clinical symptoms and the results of conventional PCR tests. the
effectiveness of the risk factors was established by odds ratio (OR).
Results: It is found that poor management of birds fighting (OR=3.72),
less educated farm foreman
(OR= 3.29) and poor filtration of the intake water (OR= 3.43) are significantly
affected the occurrence of the disease while little changes in the salinity of
shrimp ponds (OR= 0.16) decreases the odds of the disease.
Conclusion: These
findings help better develop shrimp farming across Iran, especially in
Khuzestan province.

Abstract
Background & Objectives: Bovine Tuberculosis (BTB) is one of the most important zoonoses. Mycobacterium bovis is the responsible agent of BTB in the cattle. The current study was conducted to investigate the determination factors of BTB in dairy farms covered by the tuberculin screening test.
Methods: A herd level case- control study was carried out in 124 (62 cases & 62 controls) dairy farms in the provinces of Tehran, Alborz, Hamedan, Isfahan, Qazvin, Qom, Mazandaran and Semnan. The control farms were individually matched with case farms by farm capacity and distance. Statistical analyses were done by Stata 11.2 using conditional logistic regression.
Results: Proper management of manure (OR=0.12 95% CI: 0.03-0.49), regular flaming of stalls (OR= 0.21 95% CI: 0.04-0.92) and complete fencing around the farm (OR= 0.17 95% CI: 0.03-0.81) decreased while the presence of rodents (rat) (OR= 4.90 95% CI: 1.04-23.01) increased the risk of infection. The interaction among these variables was not statistically significant
Conclusion: According to the results, there is an essential need to pay more attention to rodent control in farms.

Abstract
Background and Objectives: Salmonella contamination of broiler breeder farms is of great importance regarding transmission of the bacteria through the production chain of poultry meat. The aim of this study was to determine the prevalence and management related factors of Salmonella contamination in broiler breeder flocks in Iran.
Methods: This cross sectional study was carried out between 2013 and 2014 in 23 provinces of Iran. Fecal samples were obtained from 139 broiler breeder farms and were subjected to standard bacteriological tests for Salmonella isolation. The serogroups of isolated Salmonella were determined using standard serological tests. Relevant information of sampled holdings was acquired from the GIS system and used for risk factor detection.
Results: The prevalence of Salmonella contamination in broiler breeder holdings was 7.9% and the more positive samples were from Tehran and Fars provinces. The flock age (P = 0.019) and the number of poultry houses in the farm (P = 0.037) were major risk factors of Salmonella contamination in broiler breeder farms.
Conclusion: This investigation showed that the prevalence of Salmonella contamination in broiler breeder farms was relatively high. It is necessary to establish an appropriate program for controlling Salmonella contamination in broiler breeder farms. Regular sampling for early detection of contaminated farms would be very important in this case. Sampling from old flocks should be the first priority.

Abstract
Background and Objectives: Leishmaniasis encompasses a wide range of clinical complaints from skin injury to fatal visceral infections. Detailed information about the economic burden of the disease can help health care decision makers to estimate the magnitude of the problem, economic advantages obtained from the prevention of this disease, resource allocation, and disease management. The study was conducted to determine the economic burden of leishmaniasis in humans and animals in Iran in 2013.
Methods: The cost unit was determined through public service tariffs determined by the Ministry of Health and Medical Education and interviews with experts, and service costs were calculated by multiplying the cost unit for one person by all infected cases. The course of the disease and the services provided to patients were obtained from the review of the literature and records and interview with experts.
Results: The economic burden of leishmaniasis was estimated more than IRR 213 billion ($6,700,000). Moreover, 39%, 27%, 18%, and 16% of the costs were related to indirect costs, direct medical costs, indirect medical costs, and dogs, respectively. The average direct medical cost of cutaneous and visceral leishmaniasis was IRR 3381186 ($106) and IRR 9392832 ($295) per person, respectively.
Conclusion: The economic burden of leishmaniasis compared to some diseases such as hydatid cyst showed a smaller number( 232.3 million$). It is recommended that IIranian health politicians consider the economic burden of other diseases.

Abstract
Background and Objectives: Avian influenza (AI) is one of the most important respiratory diseases in the poultry industry that causes huge economic impacts and plays an important role in public health. H9N2 Avian Influenza Virus (H9N2 AIV) has a broad circulation and causes endemic infections in the poultry industry of the country.
Methods: A cohort study was conducted from July 2016 to November 2017 in broiler chicken farms of Qazvin Province, Iran to detect H9N2 AIV infection determinants in broiler chicken farms.
Results: Sixteen out of 34 units that were included in the study had positive PCR results. Some variables such as “type of fence around the unit”, “biosecurity”, “cooling system status”, “mean maternal antibody titers”, “location height”, “proximity to public traffic lanes” and “number of units within a radius of 1 km” had significant effects on the infection occurrence in poultry units according to univariate statistical analyses (P<0.05). However, only two of them (“biosecurity” and “cooling system status”) were statistically significant in multi-variable analyses (P<0.05).
Conclusion: Biosecurity measures should be implemented more seriously and strictly in broiler farms to reduce the impact of H9N2 AIV infection.

Abstract
Background and Objectives: The commercial layer chicken farming is one of the most important sectors of the poultry industry. This study was conducted to evaluate the status of biosecurity of commercial layer chicken farms in 9 Iranian provinces with the highest layer chicken population.
Methods: In this cross-sectional study, 202 commercial layer chicken farms were selected from nine Iranian provinces in 2019 using stratified random sampling. Then, the required data were collected using a questionnaire by presenting to the farms in person. The results are expressed as mean, standard variation, sum and adoption rate index.
Results: The results showed that the adoption level of total biosecurity measures was 68.18% in the commercial layer chicken farms in Iran. This figure was 72.11%, 75% and 60.82% for conceptual, structural and operational biosecurity measures, respectively. Among conceptual biosecurity measures, the lowest adoption level (29.20%) was for distance to the nearest garden and agriculture land. Among structural biosecurity measures, the lowest adoption level (28.96%) was for a hand disinfection spot before shed. Among the operational biosecurity measures, the lowest adoption level was for water filtrations (31.18%) and microbial testing of water (33.91%).
Conclusion: This study investigated the biosecurity status of commercial layer chicken farms in nine Iranian provinces with the highest layer chicken population and revealed some weaknesses in the implementation of these measures at conceptual, structural and operational levels.

Abstract
Background and Objectives: Foot and mouth disease (FMD) is the most significant livestock disease in the world and can cause great economic losses to the population of domestic ruminants. This study aims to investigate the economic impacts of FMD on dairy farms in West Azerbaijan province during the period of 2017-18.
Methods: Employing a questionnaire survey, this study covered all industrial dairy farms affected by the disease in eight units during the specified period. The results underwent descriptive analysis using Excel software version 2013 and SPSS version 18.
Results: Absolute (in million Rials) and relative (percent) losses attributable to FMD were categorized as follows: mortality losses amounted to 2,170 million Rials (60.6%), distress sale of livestock reached 713 million Rials (19.9%), treatment incurred 288.65 million Rials (8.1%), short-term reduction of milk production accounted for 193.35 million Rials (5.4%), extra labor costs totaled 152.4 million Rials (4.3%), abortion amounted to 35 million Rials (1%), and sampling costs were 32 million Rials (0.9%). The total losses from FMD in dairy industrial farms were estimated at 3584.4 million Rials, equivalent to 38,758 dollars at the average exchange rate of one dollar to 92,487 Rials in 2018.
Conclusion: The substantial investment in dairy farms amplifies the economic impact of FMD, resulting in prolonged recovery periods and contributing to a decline in livestock and dairy production in the province and the country.
