سقط جنين در گاو و گاوميش رايج است و به استثنا , آلودگي با سالمونلا آبورتوس اطلاعات كمتري در مورد ساير علل سقط جنين مورد بررسي و آناليز قرار گرفته است . بررسي سرو اپيدميولوژيكي در گله ئي توام با سابقه سقط ( نعداد گاو43 و گاو ميش 47 راس ) درناحيه شمال ايران انجام گرفت وسرم هاي مثبت در برابر عفونت هاي رينو تراكئيت , بروسلا آبورتوس ، زبان آبي ، بيماري اسهال ويروسي و توكسوپلاسما گوندئي بااستفاده از كيت هاي تجاري الايزا تعيين شدند. نتايج نشان داد اكثر دام هاي گله ، مبتلا به بيماري رينوتراكئيت عفوني بودند ( 05/0
P ). درسقط پيشين يا اخير گاو و گاوميش نسبت قابل توجهي مشاهده شد ( ا00/0>Pً ). نتايج نشان داد كه سقط در دام هاي سرم مثبت در برابر عوامل عفوني مورد مطالعه در مواجهه با جدايه هاي ديگر نسبت قابل توجهي وجود ندارد در حالي كه درسقط هاي پيشين و اخير هر دو نوع دام نسبت قابل توجهي وجود داشت
چكيده لاتين :
Abortion in a dairy cattle herds is observed in breeding farms of most provinces of Iran, as little information is known about causative agents on these aborted exceptional for Brucella abortus so, seroepidemiological study was conducted in a dairy cattle herds with evidence of history of abortion that was in a breeding farms in nearby of a province of Iran .Blood samples from each animal was taken and seropositivity to infectious bovine rhinotracheitis,B. abortus , blue tongue virus,bovine viral diarrhea virus were determined . The most evidence for IBR (69.8 and 3.70 % ,P>0.05) followed by B.abortus (6.32 and 6.42% ,P>0.05), BVDV (9.3 and 6.4%, P>0.05) and BTV (4.7 and 6.4%, P>0.05), whereas, all the animals were seronegative to T. gondii where with respect to age , there was a significant difference (P<0.05 ) in eropositivity to B.abortus ,and to multiple infectious agents in buffaloes .Additionally , a history of prior abortion was found to be significantly association with current abortion in cows and buffaloes ( P <0.001) .while several significant association between seropositivity to various agents and abortion were found . The study concludes that seropositivity to the studied infectious agents was not significantly associated with abortion when accounting for other covariates, while prior abortion was found to be significantly associated with current abortion in both cows and buffaloes. However, owing to the small preliminary nature of the study, small sample size, and small number of abortion events, further studies are needed to ascertain the validity of these results
