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.
