Abstract
Background: Many parasitic diseases cause parasitic complications in humans, in addition to causing significant damage to the livestock industry. This study intended to determine the prevalence pattern of some parasitic infections observed in livestock slaughtered in Kermanshah province.
Methods: Data were obtained through the examination of livestock carcasses in Kermanshah province during 2013-2017 (4367 cows, 29809 sheep, and 8995 goats) and further evaluated descriptively-analytically.
Findings: The highest prevalence rate of a parasitic disease referred to as hepatic hydatid was observed in cows with 166 cases (3.8%), followed by goats with 116 cases (1.28%), and sheep with 320 cases (1.07%), while the highest prevalence rate of Hydatid cyst was observed in cows with 252 cases (5.77%), followed by goats with 304 cases (3.37%), and sheep with 708 cases (2.37%), respectively. Fasciola infection was recognized in 115 cases of cows (2.63%), followed by 37 cases (0.41%) of goats, and 73 cases (0.24%) of sheep, and the disparity between the rates was deemed significant. In terms of the prevalence rate of Dicrocoelium infection, a considerable disparity was observed between cows with 85 cases (1.94%) and sheep with 464 cases (1.55%), while 247 cases (2.74%) were recognized in goats.
Conclusion: Moreover, a significant disparity was observed in the seasonal prevalence of infections between different livestock breeds. Ultimately, the results of this study provided essential information for the implementation of developmental and prevention programs in the monitored area.

Abstract
Background: Cryptosporidium is one of the most important pathogenic parasites in poultry because it is a zoonotic parasite, and birds and other infected animals could be a potential threat to public health. The main purpose of this study was to determine the frequency of Cryptosporidium infection in domestic fowl in Shahrekord by PCR method.
Materials & Methods: In this cross-sectional study, 110 fecal samples were collected from fowls referred to the Veterinary Clinic of Islamic Azad University, Shahrekord Branch. After DNA extraction, the samples were examined by PCR, and the frequency of infection in different genders and seasons was analyzed by SPSS statistical software.
Findings: Out of 110 samples, 15 (13.64%) samples were positive for Cryptosporidium. The rate of Cryptosporidium infection in the females was 12.85% and in the males was 15%. The results also showed that there was no statistically significant difference between two sexes (male and female) regarding the prevalence of Cryptosporidium, while the frequency of infection in cold seasons (22.22%) was significantly higher than in warm seasons (7.69%).
Conclusion: Fowls could be considered as one of the important reservoirs of Cryptosporidium infection for humans.

Abstract
Background: This study was designed to investigate the frequency and tissue distribution of Ornithobacterium rhinotracheale (ORT) in turkeys with respiratory syndrome in Isfahan province.
Materials & Methods: Totally, samples were taken from the trachea, lung, air sac, infraorbital sinus, hock joint, blood of heart, brain, liver, spleen, intestine, and kidney of 30 turkey flocks. After DNA extraction, a 787 bp fragment of 16S rRNA gene of ORT was amplified.
Findings: The PCR results revealed that 53% of turkeys were infected by ORT. The results showed that although ORT was mainly found in the respiratory tract, it could be systemic and infect some other organs, including the joints, brain, liver, spleen, and blood of heart, but could not infect the intestines and kidneys.
Conclusion: Due to the lack of a clear pattern in tissue distribution of ORT among clinical samples, it seems that other factors play a role in ORT tissue distribution, such as dose, route, type of infection, and probably prevalent serotype.
