Aborto ovino associado com infecção por Sarcocystis sp

Abstract: Infecções por protozoários têm distribuição mundial e podem causar aborto, nascimentos prematuros e ou morte fetal em diversas espécies animais. Em julho de 2004, oito ovinos Corriedale apresentaram problemas reprodutivos caracterizados por aborto e natimortalidade no terço final da gestação. Dessas oito perdas, um natimorto macho foi enviado ao Setor de Patologia Veterinária para necropsia. Alterações macroscópicas não foram observadas durante a necropsia. Lesões histológicas foram observadas principalmente n… Show more

“…Microcyst have pathogenic subsequences as an acute disease presented by abortion, fever, anemia and anorexia in early period of infection and then some chronic disorders maybe develop. On the other side, although macrocyst forming species are considered nonpathogenic, they can affect the meat quality and marketing and subsequently cause economic loss (Tenter 1995;Pescador et al 2007). From the other point of view, another aspect of differences between macro and microcyst producers is that the definitive hosts of these two types of Sarcocystis spp.…”

“…Although, in order to prohibit of probable transmission of other Sarcocystis species access of dogs to sheep herds must be denied (Adriana et al 2008).

“…Among these species S. tenella and S. arieticanis produce microscopic cysts and have pathogenic subsequences as an acute disease presented by abortion, fever, anemia and anorexia in early period of infection and then some chronic disorders maybe develop (Tenter 1995;Pescador et al 2007). On the other side, macrocyst forming species, S. gigantea and S. medusiformis are considered nonpathogenic, but they can affect the meat quality and marketing and cause economic loss.…”

“…Além disso, em decorrência da destruição provocada pela reação granulomatosa, muitos Sarcocystis são parcial ou completamente destruídos, prejudicando sua visualização. Para auxiliar na identificação do protozoário, a IHQ pode ser realizada utilizando anticorpo policlonal anti-Neospora caninum, já que antígenos de Sarcocystis apresentam reação cruzada com outros protozoários formadores de cistos (Rose 1982), embora muitas vezes com fraca reação positiva (Pescador et al 2007). Nos casos deste relato em que se utilizou essa técnica, observou-se forte marcação positiva nos cistos intactos e em meio às áreas com intensa reação inflamatória.…”
