Abortion is known as one of the most important problems from the economic, herd management and zoonotic diseases perspective in dairy cattle herds in Iran. Various factors cause abortion in cows and among them infectious factors play an important role. Previous studies have shown that three diseases, Neosporosis, Infectious bovine rhinotracheitis and Bovine viral diarrhea are the most important factors causing abortion in cows in Iran. This study aimed to determine the prevalence of these three diseases in herds in Fars province. One hundred and forty-nine blood samples taken from cows with a history of abortion in the last three months before sampling were examined using a commercial ELISA kit. Of these samples. 96 (64.4%) were positive for antibodies against Neospora caninum, 76 (51%) for antibodies against Bovine rhinotracheitis viruses and 59 (39.5%) cases for were positive antibodies against Bovine viral diarrhea. According to the results of this study, it seems that hat these agents are widely distributed in Fars province. The widespread contamination of cattle with these agents necessitates better preventive measures to control these infectious agents in Fars province.
