Virus transmission studies with Trinidadian mosquitoes

ABSTRACT

Virus isolations from Trinidad mosquitoes now total 71 strains, of which 22 represent yellow fever, 7 are Ilheus, 3 are St. Louis, and 39 are still to be identified. Attempts have been made to propagate some of these agents in forest mosquitoes as well as to effect their transmission. The studies have demonstrated that local mosquitoes may harbour these agents under laboratory conditions for considerable periods of time. Transmissions were successfully effected in the case of Mayaro and St. Louis viruses. (Summary)
