Abstract

MEDICI, Kerlei Cristina; ALFIERI, Amauri Alcindo  and  ALFIERI, Alice Fernandes. Prevalence of neutralizing antibodies against bovine herpesvirus type 1, due natural infection, in herds with reproductive problems. Cienc. Rural [online]. 2000, vol.30, n.2, pp.347-350. ISSN 1678-4596.  https://doi.org/10.1590/S0103-84782000000200025.

Serum samples of 1235 adult cattle not infectious bovine rhinotracheitis-vaccinated were analyzed by serum neutralization technique for Bovine Herpesvirus type 1 (BHV-1) antibodies. The samples were collected from 81 beef and dairy herds presenting reproductive problems, at 30 counties of Paraná State, Brazil. In dairy herds 41.9% (409/977) of the serum samples and 90.5% (57/63) of the herds were positives. In beef herds the index of positives was 50.8% (131/258) and 100% (18/18) for serum samples and herds, respectively. The total positive frequency of serum samples (43.7%) and herds (92.6%) show that BHV-1 infections has a wide dissemination in the studied region.

Keywords : bovine; Bovine herpesvirus type 1; serology; serum neutralization; reproductive problems.
