    Fescue toxicity causes substantial production losses in sheep, cattle, and horses. These losses are attributed to an endophyte, Acremonium coenophialum. However, our results indicate that Quarter horse yearlings can be fed endophyte-infected tall fescue hay for at least 106 days with no detrimental effects on either growth or exercise performance. However, these findings have not been substantiated in other classes of horses or in horses consuming endophyte-infected fescue for longer durations

    The aim of this work was the cloning of those transmembrane glycoproteins G and F from an isolate bovine respiratory syncytial viruses (BRSV) - a Brazilian isolate of BRSV, named BRSV-25-BR in previous studies, in a prokaryotic system to proceed the sequencing of larger genomic fragments. The nucleotide substitutions were confirmed and these clones may also be used in further studies regarding the biological effects of those proteins in vitro and in vivo.633552558Almeida, R.S., Spilki, F.R., Roehe, P.M., Detection of Brazilian bovine respiratory syncytial virus strain by a reverse transcriptase-nested-polymerase chain reaction in experimentally infected calves (2005) Vet.
