| الوصف: | The objective of this work was to investigate the presence of bovine herpesvirus type 1 (BoHV-1) in follicular fluid and in cumulus-oocyte complexes (COC) recovered from naturally infected cows but with no clinical signs of the disease. Cows that were seropositive (n=38) or seronegative (n=8, control) to infectious bovine rhinotracheitis were selected after a serum neutralization test in microplates. The presence of the virus was investigated by PCR in COC and in follicular fluid. Viral DNA was not found in any of the samples. The obtained results suggest that serologically positive cows with no clinical signs of the disease offer negligible risk of transmitting BoHV-1 by COC or follicular fluid. Resumo: O objetivo deste trabalho foi investigar a presença do herpesvírus bovino tipo 1 (BoHV-1) no fluido folicular e em complexos cumulus-oócito (COC) coletados de vacas naturalmente infectadas mas sem sinais clínicos da doença. Vacas soropositivas (n=38) ou soronegativas (n=8, controle) para o vírus da rinotraqueíte infecciosa bovina foram selecionadas por prova de soroneutralização em microplacas. A presença do vírus foi investigada por PCR em COC e fluido folicular. O DNA viral não foi encontrado em qualquer das amostras. Os resultados obtidos são indicativos de que vacas soropositivas, mas sem sinais clínicos da doença, oferecem risco negligível de transmissão do BoHV-1 por COC ou fluido folicular. |
