Cattle Farms

A serological survey for bovine viral diarrhoea virus (BVDV) antibodies on a collection of 1295 serum samples obtained from 6-12 months old cattle originating from 45 farms in Slovakia was carried out. On 13 farms more than 90% of the examined animals were seropositive, on 14 farms 71-90% seroprevalence was observed, on 13 farms only 50-70% animals were found to be positive for BVDV antibodies, while the remaining 5 farms showed fewer than 50% seropositive animals. The average incidence of BVDV antibodies (around 70%) was similar as determined 30 years ago. Of 84 serum samples from seronegative animals originating from 14 farms in which 70-98% seropositivity was observed, six were positive in Ag-BVDV ELISA indicating persistently infected (PI) cattle. On a farm to which animals were imported from abroad, a BVD outbreak was observed. Of 110 animals tested, four were positive in Ag-ELISA indicating the presence of PI cattle on this farm. Genetic typing of two isolates from imported animals performed by RT-PCR (324/326 primers from 5´-UTR), sequencing of PCR products and computer-assisted phylogenetic analysis revealed that they belong to BVDV-1h group.

Ovine pestiviruses have the potential to reduce productivity in the British sheep flock. However, their prevalence and impact are currently poorly understood. This study aimed to estimate the exposure to pestiviruses in adult breeding ewe stock. Blood samples collected for metabolic profiling before lambing were tested using an ELISA that detected antibodies raised to both bovine viral diarrhoea virus and Border disease virus. A group of 15 animals were tested per flock. A total of 34 farms were tested, of which 13 had at least one seropositive animal. In those positive flocks between one and nine of the animals tested antibody-positive. Positive flocks were identified in all regions of Great Britain. This work suggests that exposure to ovine pestiviruses is widespread, and that it is timely to investigate flock-level prevalence and possible production impacts of endemic infection.

Bovine viral diarrhoea (BVD) virus is a cosmopolitan pestivirus of animals which is associated with diarrhoea, immunosuppression and synergy with other pathogens. This study was conducted to establish the prevalence of anti-BVD virus antibodies in healthy Zambian adults and those with asymptomatic and symptomatic HIV disease. Sera from 1159 adults were tested for anti-BVD virus antibodies using the indirect immunofluorescence test and the confirmatory Western blot. Of the 1159 sera examined, 180 (15.5%) showed significantly elevated titres of anti-BVD antibodies. These included 70 out of 477 (14.7%) HIV-negative healthy adults; 73 out of 480 (15.2%) of HIV-positive asymptomatic individuals; 23 out of 129 (17.8%) HIV-seropositive patients with associated illnesses excluding diarrhoea; and 14 out of 73 (19.2%) of HIV-seropositive patients with chronic diarrhoea. HIV-seropositive patients with chronic diarrhoea or associated illnesses appear to have significantly increased seroprevalence of anti-BVD virus antibodies ( P = >0.01). The mechanism of interaction between BVD virus and HIV infections and the synergistic effects with other opportunistic pathogens in humans requires definition.
