A 3-year-old female fallow deer was subjected to the necropsy and virological testing, due to a suspected infectious disease in the herd of farmed deer in the Southeastern region of Poland. The animal was found negative for the presence of BVDV, BoHV-1, BTV, and EHDV antibodies and BVDV antigen. The toxicological examination did not reveal any coccidiostats, mycotoxins, rodenticides, carbamate pesticides,...
Restriction fragment length polymorphism (RFLP) analysis was developed for genetic ty ping of Polish strains of bovine viral diarrhoea virus (BVDV). The method was applied using 60 BVDV isolates, which included BVDV genotype 1, subtypes a, b, d, e, f, and g, and genotype 2a. RT-PCR products of the 5'untranslated region (5'UTR) were digested using three enzymes. Restriction patterns classified the...
The study presents the analysis of the findings of 234 post-mortem examinations on free-ranging and captive European bison selectively culled or having fallen between 2008 and 2013 in Białowieża Primeval Forest. Pneumonia, emphysema, nephritis, bodily traumas, and intestinal lesions were observed in 106 (45.3%), 77 (32.9%), 82 (35.0%), 68 (29.1%), and 56 (23.9%) animals respectively and were the most...
The aim of the study was to evaluate the prevalence of Schmallenberg virus (SBV) specific antibodies in ruminants from 13 Polish provinces, sampled between January 2010 and August 2013. A total number of 1813 serum samples from cattle, sheep, goats, mouflon, wild and farmed cervids, and European bison were tested by ELISA for viral nucleoprotein antibodies. First SBV seropositive animals were identified...
Two issues concerning virus detection and identification of persistently infected (PI) cattle were analysed in the study: 1) interference by maternal antibodies and 2) discrimination between PI and transiently infected (TI) animals. Antigen ELISA and RT-PCR based methods were compared using serum samples from natural and experimental PI and TI calves. RT-PCR and realtime RT-PCR using primers within...
The aim of the study was to evaluate the status of bovine viral diarrhoea virus (BVDV) infection in selected dairy herds in Poland with the use of commercial enzyme linked immonosorbent assay for the detection of specific antibodies (BVDV-Ab ELISA) and reverse transcription-polymerase chain reaction (RT-PCR) for the detection of viral RNA, using bulk tank milk (BTM) samples. Two hundred and thirty-one...
This paper describes the first characterisation of bovine respiratory syncytial virus (BRSV) detected in the nasal swabs collected from young yearlings with clinical signs of lower respiratory tract illness from the northern regions of Poland. RT-PCR products of the BRSV gene encoding glycoprotein G were sequenced and subsequently compared to the reference nucleotide sequences of 19 BRSV strains from...
