进行了一些研究，以确定西非福氏Acedes fowleri（Charmoy）菌株传播裂谷热病毒的能力。感染率范围从摄入101.3-1.6噬斑形成单位（PFU）病毒的蚊子的11%（12/105）到摄入≥ 101.3-1.6噬斑形成单位（PFU）病毒的蚊子的89%（206/23）。106.4 PFU。病毒传播具有时间依赖性。在5-9次孵育后，只有34%（23/68）的受感染蚊子传播了病毒，而在感染性血餐后26天或更长时间内，76%（22/29）的受感染蚊子传播了病毒。经口接触裂谷热病毒埃及株（ZH 501）或中非株（ArB 1976）的蚊子的感染率和传播率相似。同样，Ae的传播率（53%，50/94）和病毒滴度（平均值= 105.4 PFU）相似。Fowleri接种任一病毒株。43%（13/30）的再喂养期间，经口暴露后传播感染的蚊子传播病毒。我们得出结论，Ae。fowleri应被视为裂谷热病毒的潜在载体。
Studies were conducted to determine the ability of a West African strain of Acedes fowleri (Charmoy) to transmit Rift Valley fever (RVF) virus. Infection rates ranged from 11% (12/105) for mosquitoes that ingested 101.3-1.6 plaque-forming units (PFU) of virus to 89% (206/23) for those ingesting .gtoreq. 106.4 PFU. Dissemination of virus was time dependent. Virus was disseminated in only 34% (23/68) of the infected mosquitoes after 5-9 incubation, compared with 76% (22/29) in those held 26 or more days after the infectious blood meal. Infection and dissemination rates were similar for mosquitoes exposed orally to either an Egyptian (ZH501) or a central African (ArB 1976) strain of RVF virus. Likewise, transmission rates (53%, 50/94) and viral titers (mean = 105.4 PFU) were similar for Ae. fowleri inoculated with either viral strain. Mosquitoes with a disseminated infection after oral exposure transmitted virus during 43% (13/30) of the refeedings. We conclude that Ae. fowleri should be considered as a potential vector of RVF virus.
