Serological testing is an additional method to confirm infection, and the patterns observed here are similar to those observed in previous reports of acute BVDV
infections (BRUM et al.
In a second experiment, 7-week-old calves with circulating maternal antibody to BVDV
were given one of two vaccines: a modified live vaccine containing the strains BVDV
1 and BVDV
2 or a killed vaccine containing BVDV
1 and BVDV
Epidemiological studies show that cattle are the main hosts for BVDV
and an infection source for swine and other wild ruminants, either through direct contact (LIESS & MOENNIG, 1990) or through the use of contaminated bovine milk and milk derivatives used as components in swine feed (TERPSTRA & WENSVOORT, 1988).
Accordingly, previous reports suggest that BVDV
may spread (and cause severe disease) through vaccination with contaminated products (12-14).
Phylogenetic, antigenic and clinical characterization of type 2 BVDV
from North America.
A new focus would include recent research by unit microbiologist John Neill in which technology originally developed for cancer studies in humans is being applied against BVDV
However, lissencephaly has not yet been described in cases of malformations due to BVDV
Por outro lado, a resposta sorologica induzida pela grande maioria das vacinas contra o BVDV
, especialmente contra o BVDV
-2, foi indetectavel, situacao que e inadequada, tanto do ponto de vista imunologico quanto do ponto de vista de controle e prevencao dessa infeccao.
Bulk milk for antibody seroprevalences to BVDV
and BHV-1 in a rural region of Peru.
Collectively, the study results demonstrate that the rigorous virus inactivation steps currently used by Aventis Behring in the production of plasma-derived products successfully inactivate WNV and BVDV
(and related viruses).

Ambos os extratos de propolis examinados apresentaram uma melhor atividade frente ao BVDV
do que frente aos outros dois virus, embora as diferencas de atividades entre BVDV
e CAV-2 tenham sido pequenas (Tabela 1).
