Transmission studies in mosquitoes (Diptera: Culicidae) with disseminated Rift Valley fever virus infections.

摘要: Experiments were conducted to determine the ability of mosquitoes with disseminated Rift Valley fever (RVF) virus infections transmit this by bite. Transmission rates for inoculated RVF ranged from 0% (0/21) Anopheles stephensi 100% (92/92) Culex pipiens. Aedes fowleri, taeniorhynchus, and triseriatus transmitted about 50% time. Providing that extrinsic incubation period a mosquito species had been completed, was not affected time postinoculation, number ovarian cycles or whether probed, partially engorged, fed repletion. Similarly, when multiple probes during single blood meal (i.e., they on several different animals), transmission order feeding. Thus, impact vector capacity probings is unable obtain complete given feeding attempt may require further study. Also, wide variation in observed emphasizes need rates, merely infection evaluating competence species.
