Genetic diversity of international bovine viral diarrhoea virus (BVDV) isolates: identification of a new BVDV-1 genetic group.
In the last decade, several studies were performed to characterise bovine viral diarrhoea virus (BVDV) isolates and define genetic groups by genotyping. Much data is now available from GenBank, predominantly sequences from the 5' untranslated region (5'-UTR). In order to find out whether genetic grouping of isolates from different countries could be harmonised, 22 new isolates from five countri...
متن کاملPersistent bovine viral diarrhea virus (BVDV) infection in cattle herds
Bovine viral diarrhea virus (BVDV) is a significant pathogen associated with gastrointestinal, respiratory, and reproductive diseases of cattle worldwide. It causes continuous economic losses to the cattle industry primarily due to decreased reproductive performance. The ability of virus to cross the placenta during early pregnancy can result in the birth of persistently infected (PI) calves. P...
متن کاملContamination of Foetal Bovine Serum with Bovine Viral Diarrhoea Virus (bvdv)
Twelve batches of commercially available foetal bovine sera were tested for the presence of bovine viral diarrhoea virus (BVDV) and BDVD antibodies. The antibodies were found in three batches coming from two suppliers. Fragments of BVDV genome were present in five of these batches when tested by RT-PCR. All of them were type 1 BVDV according to a direct sequencing of PCR products. However, the ...
متن کاملBovine Viral Diarrhoea Virus (bvdv) Infection in Pregnant Cows and Their Foetuses
The aim of the study was to characterize bovine viral diarrhoea virus (BVDV) infection in pregnant cows and their foetuses. Blood samples from 64 clinically healthy cows, determined as pregnant after slaughter, and from their foetuses were collected into tubes with and without EDTA. In total 128 blood samples were examined for BVDV antibodies and 128 leukocyte samples for BVDV antigens by direc...
متن کاملFatal congenital anaplasmosis associated with bovine viral diarrhoea virus (BVDV) infection in a crossbred calf.
Clinical disease resulting from the vertical transmission of Anaplasma marginale has only been reported on 5 occasions despite studies demonstrating successful in utero transmission. During the reported experimental induction of congenital anaplasmosis in calves, the outcome was variable but mostly led to inapparent or mild infection. There are previous case reports of fatal congenital anaplasm...
