Common, Emerging, Vector‐Borne and Infrequent Abortogenic Virus Infections of Cattle

摘要: Summary This review deals with the aetiology and diagnosis of bovine viral abortion. While abortion rates on beef dairy cattle farms usually do not exceed 10%, significant economic losses because storms may be encountered. Determining cause abortions is a challenge, it generally remains obscure in more than 50% necropsy submitted foetuses. Bovine diarrhoea virus herpesvirus-1 are most common viruses causally associated farmed globally. Rift Valley fever bluetongue important insect-transmitted abortogenic viruses. The geographic distribution these two primarily dependent insect vector, but direct transmission possible. Recent global warming subsequent vector expansion, coupled increase international trade animals animal products, have been factors recent advances those herpesviruses-4 5 cattle, as well other less frequent vector-borne including epizootic haemorrhagic disease virus, Aino Wesselsbron lumpy skin discussed.
