The mechanical transmission of equine infectious anemia (EIA) virus by Tabanus fuscicostatus was investigated. In 1 of 7 transmission trials, a single horsefly transmitted EIA virus from an acutely infected pony to a susceptible pony. Groups of horseflies isolated for 3, 10, or 30 minutes before refeeding transmitted EIA virus, whereas those isolated for 4 or 24 hours did not. Data from field studies indicate that the home range or flight distance of horseflies may exceed 4 miles. That information together with our observations suggest that segregation of infected horses (usually defined as at least 200 yards from susceptible horses) as a control measure for EIA may not be an adequate safeguard against transmission in areas where horseflies are numerous.
对黑纹斑虻传播马传染性贫血（EIA）病毒的机制进行了研究。在7次传播试验中的1次试验里，一只厩螫蝇将EIA病毒从一匹急性感染的小马传播给了一匹易感小马。再次喂食前隔离3分钟、10分钟或30分钟的厩螫蝇群体能够传播EIA病毒，而隔离4小时或24小时的厩螫蝇群体则不能传播。野外研究数据表明，厩螫蝇的活动范围或飞行距离可能超过4英里。这些信息与我们的观察结果表明，将感染马匹隔离（通常定义为与易感马匹至少相距200码）作为EIA的一种控制措施，在厩螫蝇数量众多的地区可能不足以防止病毒传播。
