Aspectos anatomopatológicos do parasitismo por nematódeos da superfamília filarioidea em capivaras (hydrochoerus hydrochaeris) de vida livre no Centro-Oeste brasileiro / Anatomic pathology aspects of the parasitism by cruorifilaria tuberocauda in capybaras (hydrochoerus hydrochaeris) in midwestern Brazil

São descritos dois casos de parasitismo por Cruorifilaria tuberocauda em capivaras de vida livre no Distrito Federal, Brasil. Macroscopicamente, observou-se nas superfícies de corte dos rins espessamento acentuado de vasos das regiões cortical e córtico-medular. Microscopicamente, havia arterite proliferativa e granulomatosa acentuada associada a filarídeos intralesionais consistentes com Cruorifilaria tuberocauda. Esse é o primeiro relato do parasitismo por esse filarídeo em capivaras no Distrito Federal.

This report describes two cases of parasitism by Cruorifilaria tuberocauda in wild capybaras (Hydrochoerus hydrochaeris) from Distrito Federal, Brazil. Grossly, there was marked thickening of vessels wall of the cortical and corticomedullary regions of both kidneys. Microscopically, there was severe proliferative and granulomatous arteritis associated with intralesional filarids, consistent with Cruorifilaria tuberocauda. For the first time this filarid is reported parasitizing capybaras in Distrito Federal, Brazil.

Brugia timori: experimental infection in some laboratory animals.

Experimental infection with Brugia timori of 7 jirds (Merionesunguiculatus), 4 cats and 2 monkeys (Macaca fascicularis) is described. Although no microfilariae were detected by examining 20 microliter samples of tail blood of jirds, adult worms were recovered from 6 of the 7 jirds at autopsy 69-141 days following infection. Some worms were gravid and microfilariae were found in visceral blood of 2 animals. The adult recovery rate in jirds was 16%; the male to female ratio was 1:3. In cats patent infection developed in 95-105 days but microfilaraemias were of low level and transient. No parasites were recovered from monkeys.
