bovine neosporosis caused by the apicomplexan protozoan parasite n. caninum, was initially recognized in 1989 and is now reported as a leading infectious cause of reproductive failure in dairy cattle in world wide. the aim of this study was to determine the seroprevalence of n. caninum infection in industrial dairy cattle of hamedan province (west of iran) by elisa method. blood samples were co...

the purpose of this study was to analyze the instruments of risk management in the industrial dairy cattle farms in uromieh and khoy counties. the industrial dairy cattle farms in uromieh and khoy counties (n= 84) altogether constituted the statistical population of the study. by use of simple sampling method, 50 cattle farmers were selected as sample. the research design was a survey method on...

Background: BIV is a well-known bovine immunosuppressive cause, but its pathogenesis has not been well characterized. In recent years, it has been hypothesized that infection with BIV might predispose cattle to be infected by other agents. OBJECTIVE: This study was performed to investigate of BIV and Brucella co-infection so that in the future more studies will be done on the issue of predispos...

Bovine Viral Diarrhea Virus (BVDV) is a Pestivirus of the Flaviviviridaefamily that infects cattle, and its widespread distribution can cause substantial economic losses worldwide. The aims of this study were: (1) to estimate the prevalence of animals persistently infected (PI) with BVDV in industrial dairy cattle herds in suburb of Mashhad- Iran; and (2) to compare the occurrence of persistent...

background: eimeria infection is an important part of protozoal infection in ruminants which causes economic lost in animal husbandry of iran and worldwide. therefore it is important to implement effective control programs on the prevalence and diversity of eimeria species in livestocks. objectives: this study was aimed to determine prevalence and eimeria species diversity in dairy cattle with ...

Background and Objective: As the most important human food source, milk and dairy products may lead to infectious diseases due to non-compliance with health standards. Brucellosis is one of the critical zoonotic diseases that affect the human population. Humans are usually infected by Brucella spp. via contaminated milk and dairy products and direct contact with infected animals. Methods: This...
