Abstract:
... African swine fever (ASF) is a notifiable disease with serious socio‐economic consequences that has been present in wild boar in the Baltic States and Poland since 2014. An introduction of ASF is usually accompanied by increased mortality, making fallen wild boar and hunted animals with signs of disease the main target for early warning and passive surveillance. It is difficult, however, to encour ...

Abstract:
... Due to its impact on animal health and pig industry, African swine fever (ASF) is regarded as one of the most important viral diseases of pigs. Following the ongoing epidemic in the Transcaucasian countries and the Russian Federation, African swine fever virus was introduced into the Estonian wild boar population in 2014. Epidemiological investigations suggested two different introductions into th ...

Abstract:
... The associations between herd bovine herpesvirus 1 (BHV-1) seroprevalence, along with other infectious and farm management factors with bovine respiratory disease (BRD) in dairy calves and heifers, were investigated. Serum samples from 103 dairy cattle herds were analyzed for antibodies against BHV-1, bovine respiratory syncytial virus (BRSV), bovine viral diarrhea virus (BVDV), and Mycoplasma bov ...

Abstract:
... The objectives of this study were to reassess the herd level and within-herd prevalence of bovine herpesvirus 1 (BHV1) infection in Estonian dairy cattle, estimate the sensitivity and specificity of the enzyme-linked immunosorbent assay (ELISA) for bulk tank milk (BTM) testing and determine the risk factors related to high prevalence of the infection in herds. To estimate the herd prevalence, BTM ...
