Bovine Viral Diarrhoea Virus (BVDV) Infection in Pregnant Cows and Their Foetuses. Bulletin of the Veterinary Institute in Pulawy, (50), 315-317.0042-4870https://hdl.handle.net/20.500.12395/20365The 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 direct and indirect ELISA. Thirty-six out of 64 (56.25%) sera from adult cows were detected as seropositive while only one (1.56%) serum from a foetus was seropositive. Leukocyte samples from pregnant cows were negative for BVDV antigen while BVDV antigen was detected in only one (1.56%) leukocyte sample from a foetus. A foetus, 4-month-old, belonging to these of seropositive cows, was detected as BVDV antigen negative and antibody positive. The other one, 2-months-old, was found as antigen positive and antibody negative.eninfo:eu-repo/semantics/openAccesscowsfoetusBVDVELISAArticle50315317N/AWOS:000240821600007Q3
