“…Other studies investigated the presence of virus particles in follicular fluid and in COC recovered from animals artificially infected, or naturally infected but in the acute period of the disease (Bielanski et al, 1993;Bielanski & Dubuc, 1994;Stringfellow & Givens, 2000). The level of infectivity in all these experimental models is unlikely to occur in naturally infected animals out of the acute phase of the disease, when the virus spreads and contaminates the reproductive tract (Guerin et al, 1997). Therefore, the obtained results bring an important contribution to the risk analysis of in vitro-produced embryos.…”

“…The intrafollicular oocyte can incur either genomic or cellular contamination. Genomic contamination has never been highlighted [33] and intracellular contamination has only been reported for the Porcine parvovirus [2], Campylobacter fetus [15] or Leptospira hardjo [11,17]. Indeed, the role of the surrounding cells is of great importance in the contamination process during IVF.…”

“…Most particularly, fetal calf serum can be contaminated with viruses, such as BVDV [33,47]. Irradiation of commercial sera may limit those risks, but this procedure is not always applied.…”

“…Há, no entanto, sempre o risco da introdução de agentes patogênicos (KNIAZEFF et al, 1975;ROSSI et al, 1980;ERICKSON et al, 1991;GUERIN et al, 1997;ROEHE et al, 1998;BROCK, 1998;STRINGFELLOW et al, 2000;FIGUEIRÓ et al, 2000). Mesmo com a melhora dos métodos de coleta e processamento do soro, que possibilitaram a eliminação de contaminantes exógenos, certas viroses podem permanecer e, os métodos de inativação pelo calor ou radiação gama não são inteiramente eficazes na eliminação da contaminação vírica (PALASZ & DEL CAMPO et al, 1995).…”
