Seven isolates of the New Jersey serotype of vesicular stomatitis (VSNJ) virus were obtained from pooled specimens of phlebotomine sand flies, Lutzomyia shannoni Dyar, collected on Ossabaw Island, Chatham County, Ga., in 1989 and 1990. Three isolates, including two from males, were obtained from light-trapped sand flies in 1989. Four isolates were obtained from pools of sand flies collected from hollow trees in 1990. Three of the latter pools contained from 4.0 to 4.7 log10 of plaque-forming units of virus per ml, suggesting that the positive flies in these pools had supported VSNJ virus replication. One of these high-titered isolates was obtained from a pool of male sand flies. These data provide further support for the hypotheses that L. shannoni is a biological vector of VSNJ virus at this enzootic focus and that transovarial transmission of the virus occurs in nature.
1989年和1990年在佐治亚州查塔姆县奥萨巴岛采集的沙氏白蛉（Lutzomyia shannoni Dyar）混合标本中获得了7株新泽西型水疱性口炎（VSNJ）病毒分离株。1989年从诱捕的沙蝇中获得了3株分离株，其中包括2株来自雄性沙蝇的分离株。1990年从空心树中采集的沙蝇群体中获得了4株分离株。后一组中的3个群体每毫升含有4.0至4.7 log10的病毒空斑形成单位，这表明这些群体中的阳性沙蝇支持了VSNJ病毒的复制。这些高滴度分离株中的一株是从一群雄性沙蝇中获得的。这些数据进一步支持了以下假设：在这个动物疫病疫源地，沙氏白蛉是VSNJ病毒的生物传播媒介，并且该病毒在自然界中存在经卵传播。
