Salmonellas are geram negative, facultative anaerobic bacilli from of the family enterobacteriaceae that spread widely in the environment. They cause human and animal infectious diseases in a wide range as enteric pathogens and deadly in cases of septicemia. Salmonellas transfer by direct contact, contaminated food and water and asymptomatic carriers.
In this study, patiant calves were examined in a dairy farm following refer of fifteen under one month year old dead calves. High fever, weakness, dehydration, white to gray smelly mucus diarrhea and neurological symptoms in two cases were observed.
Mucofibrinous enteritis, bowel wall thickening, swollen mesenteric lymph nodes, petechiae on serous surfaces, liver and spleen congestion, petechiae and thickening of the meningeal membranes were observed in autopsy examinatin. Microbiological and histopathological samplings were performed. Histopathological examination showed congestion, edema, presence of mononuclear inflammatory cells in lung, congestion, mass of lymphocytes and macrophages in liver, congestion, epithelial mucus removal and presence of a pseudo- membrane in intestine, meningeal thickening, hyperemia and presence of inflammatory cells with perivascular cuffing in brain. After differentiating cultures Salmonella spp. were isolated, as Salmonella species. Antibiotic therapy was performed after antibiogram test with prescription of Enrofloxacin.
Salmonellosis may incur significant social and economic costs as a result of lost productivity, and impacts on industry and agriculture. The centers for disease control and prevention has ways to prevent salmonellosis.

Brucellosis is one of the zoonotic diseases that transmit from animal to men and it is one of the main health problems. The purpose of this study was to investigate a descriptive epidemiology of the disease in Qom province during years of 2009- 2010.
We analyzed retrospectively 83 patient’s cases of brucellosis who were diagnosed and treated in the Infectious Disease Clinic of medical centers from 2009 to 2010 in Qom. The diagnosis was based on clinical findings and serologic results and/or blood culture confirmations.
from 83 patients, 47 patients (%56.6) were male and 36 (%46.7) were female. The highest incidence rate of disease belongs to individuals that had contact with sick animals (with incidence of %59). Also the other groups with high incidence of brucellosis were the ages between 21 to 40 years old, housekeeper women (%33.7) and individuals that live in urban region (%58). Also the most cases were occurred in summer season (%49.3) and the most common infection resource was contaminated milk and dairy products. Additionally, according to the statistic of the results of the present study incidence of the brucellosis had a rising trend in the years that the study was conducted (40 cases in 1388 and 43 cases in 1389); it should be mentioned that one of the cases (%1.2) had Afghani originality.
According to the present study results and because of importance of animal husbandry in Qom province, controling and eradication of brucellosis in this province is necessary.

Leishmaniasis can be considered as a zoonotic disease that is caused by leishmania. This disease caused major problems in some parts of Iran such as Golestan Province. Present study aimed to investigate some epidemiological aspects of cutaneous leishmaniasis and to indicate the importance of controlling this problem in Golestan province. This cross-sectional and descriptive study was conducted from 2010 to 2012. Epidemiological data, including age, sex, location, occupation, number of wounds, wound position and residence or travel history of 1715 patients infected to cutaneous leishmaniasis were recorded and analyzed . Most of the patients were suffered from zoonotic cutaneous Leishmaniasis (ZCL( there was a difference between number of male and female patients afflicted to Leishmaniasis (male were more afflicted to Leishmaniasis). Most of the patients aged from 1-9 years old. Among the job groups, children subjects were mostly afflicted to Leishmaniasis. Autumn had the most seasonal prevalence (68.4%). Attention to incremental trend of cutaneous Leishmaniasis in Golestan province, finding the causes of infection in this province should be considered as priority in order to properly control and prevent spreading of the disease.

Hydatid cyst is a kind of parasitic disease common to humans and animals which is caused through the larval stage of Echinococcus granulosus. This has caused many economic and health damage such as confiscating impurities of animal feed at the slaughterhouse.
The current cross-sectional study was aimed at assessing the prevalence of hydatid cysts in slaughtered livestock at Sari slaughterhouse and took place within the years of 2010 to 2012.
From among a total of 282,394 animals slaughtered during the years of 2010 to 2012, 45,891 head of cattle (26/8 %), 144,211 sheep (14/8 %), and 92,292 goats (15 %) were infected with hydatid cysts. The effect of seasons on the prevalence of hydatid cyst revealed the maximum amount of contamination is first in winter and then fall.
Prevention of parasite’s life cycle in the final host and interface by controlling the stray dogs and hygienically destructing the carcasses and/or offal of infected animals is highly important in control of hydatid cyst.

SummuryTaniasis, caused by Tania saginata, is one of the common diseases between human and cattle. Human infection with adult worms and larval stage of the parasite in cattle was reported from different regions of Iran. The aim of this study is description of the rate of infection and health care importance of the cysticercus bovis infection in cattle in Hamadan industrial slaughterhouse in 2014.
This is a cross sectional –analytical descriptive study. In this study the presence of C. bovis in the scapular muscles, heart and thigh, between the ribs and diaphragm and liver of the cattle were surveyed. Both alive and calcareous cysts were studied. Data were analyzed using SPSS- 21 software, descriptive statistics and chi-square test.
The prevalence of C. bovis in 2000 studied cattle was 3.8%. The highest rate of infection was found in heart muscle and there was a statistically significant difference between the rate of infection in different organs (p

Brucellosis is very important in most parts of the world, especially in developing countries in terms of public health and its impacts on socio-economic status. The present study was conducted to determine the epidemiology of brucellosis in Sistan and Baluchistan province in the years 2009-2015.
This cross-sectional descriptive study was conducted on all cases of brucellosis (680 cases) in Sistan and Baluchistan Province identified by the public and private sectors during the years 2009 to 2015. Data were analyzed by using SPSS version 20 with the significance level of 0.05.
The average incidence rate in the present study was 27.5 per hundred thousand people, with the most in Khash (38.03) and the lowest in Saravan (0.36). Most Of the patients (26.9%) placed in the age group of 50 and over, 55.9% were female and 88.5% were rural.

Data analysis was performed using spss-20 statistical software, descriptive statistics and Chi-square test. In this study the frequency of cysticercus infection was 14% in cattle, 28.5% in sheep and 10% in goat. All together the frequency of infection in slaughtered livestock was 17.5%. The rate of Infection in females was more than males (p=0.02). There was a statistical significant difference between the rate of Infection and seasons of the year (p

Helminthes parasite infections of goats are a major problem throughout the world and are responsible for economic losses in a variety of ways.
A total of 198 goats were examined. Nematodes and cestodes were removed from abomasums, small and large intestines, and kept in Formalin 10% for further diagnosis.
The results of the study indicated that examined animals were infected as follows:Haemonchus contorts (13.63 %), Parabronema skrjabini (11.61 %), Trichuris globulosa (8.58 %), Camelostrongylus mentolatus (3.5%), Stilesia globipunctata (3.5%), Moniezia expansa (3.5%), Ostertagia circumcincta (1.01 %), Oesophagostomum columbianum (0.5%), Marshallagia marshalli (0.5%), Nematodirus spp (0.5%), Trichuris ovis (0.5%), Avitellina centripunctata (0.5%).
Therefore, it seems that management and health levels of goats’ flocks should be improved to increase public health.
