Para a investigação das causas de aborto eqüino na região de Curitiba, realizou-se a coleta e processamento do material de casos de aborto para bacteriologia, virologia e histologia; e um levantamento estatístico geral dos casos de aborto. Durante três anos, foram acompanhadas 674 gestações, das quais 9,2% resultaram em aborto. Com relação a abortos gemelares, verificou-se um índice de 4,5% em um total de 132 casos analisados. O material de 21 fetos foi processado com o intuito de isolar-se o Herpesvírus eqüino tipo 1, obtendo-se o isolamento em 4 casos (19,0%). Foram examinados para bacteriologia um total de 38 fetos, dos quais 44,7% foram considerados bacteriologicamente positivos. As bactérias isoladas com maior freqüência foram: Streptococcus spp., Klebsiella spp., Escherichia coli, Pseudomonas spp. e Staphylococcus spp.. Foram descritas as alterações encontradas no exame histológico da maioria dos casos de aborto de origem bacteriana e viral.
Abstract
This research was undertaken with the aim of establishing the main causes of equine abortion in the Curitiba area. It has been established that during the period of three years occurred a total of 9.2 per cent abortions among 674 gestations studied. From 50 aborted fetuses, different biological material was collected for bacteriology, virus and histopathology analysis. A total of 4.5 per cent of twin abortions were observed among 132 cases of abortions studied. The equine Herpesvirus type 1 has been successfully isolated from 4 cases, among 21 fetuses studied. On the other hand, 44.7 per cent from 38 fetuses studied were considered positive for bacteriological testing. The most frequent bacteria recovered were Streptococcus spp., Klebsiella spp., Escherichia coli, Pseudomonas spp. and Staphylococcus spp. The alterations found in the histological examination of the majority of bacteriological and virological abortion cases were desccribed.
