The prevalence of bovine viral diarrhea virus (BVDV) in 406 cattle was evaluated of both sexes and older than 6 months. Animals belonged to 114 small farmers from three rural communities of the province of Espinar, Cusco, Peru. Blood samples were collected according to three age groups Ɩ-12, 13-23, >24 months old). Serum samples were tested for antibodies against BVDV using the viral neutralization test. The 56.2 ± 4.8% 鴤/406) of samples had antibodies against BVDV. Persistently infected animals were not detected. Antibodies were present in the three age groups, but the highest prevalence .4%) was detected in animals older …

The aim of this study was to determine the phenotype and genotype of Bovine Viral Diarrhoea Virus (BVDV) in Peruvian cattle. During the period 1998-2007, tissues of aborted fetus, blood, serum or plasma samples of bovine with acute infection or persistently infected from dairy herds of various locations in the country were collected and the BVDV antigen was detected by immnunofluorescence or capture ELISA tests, and positive samples were inoculated en BVDV free BT cells and cultured until third passage to determine the biotype. Both animal tissues and third passage of positive samples were tested by a Real Time Reverse …

The objective of this study was to determine the prevalence of bovine viral diarrhea virus (BVDV) and persistently infected (PI) animals in dairy herds located in Majes, Arequipa, Peru. In the first phase, 204 bulk tank milk samples from herds were collected and sent to the local commercial processing plant in Majes for detection of antibodies against BVDV by indirect ELISA test. In the second phase, 286 blood samples from 57 were collected strong positive (Optical Density [OD] ≥ 0.900) for the detection of herds antibodies against BVDV and in PI animals by the indirect and capture ELISAs respectively. In …

Antibodies against viral bovine diarrhea virus (BVDV) and of BVDV antigen in serum samples Were evaluated from cattle aged 10 to 23 months (n = 148) from a dairy herd disease eradication where the has-been carrying out since 2002. The herd is located in Santa Rita, Arequipa, Peru, and samples were collected twice on a 30-day interval. Antibodies against BVDV and BVDV antigen were analyzed by viral neutralization and capture ELISA tests respectively. Neutralising antibodies against BVDV were detected in 6.8% (10/148) of animals, and most reactors were 19 to 23 months of age. The antibody titer ranged from 8 …
