吸血节肢动物作为乙型肝炎病毒的媒介已受到注意。热带和其他地区的大多数人群显示现今或既往有过HBV 感染的证据,这些地区的人群常终生暴露于蚊子或其他节肢动物。本报告通过检测从西非塞内加尔农村居民床上采集到的无血充盈臭虫中的HBsAg,发现有较高的乙型肝炎病毒野外感染率。臭虫是在四个不同时期(1975年8月、1976年3月、1976年9月、1976年11月)从塞内加尔农村小屋里采集的。前三批采集的臭虫在捕获后几小时内用冷冻杀死并贮存 Vampire arthropods have received attention as vectors for hepatitis B virus. The majority of people in the tropics and elsewhere show evidence of current or past HBV infection, and people in these areas are often exposed to mosquitoes or other arthropods for the rest of their lives. This report examines HBsAg in bloodless bedbugs collected from Senegal’s rural residents in West Africa and found a high prevalence of hepatitis B virus infection. Bed bugs were collected from Senegalese rural huts in four different periods (August 1975, March 1976, September 1976, November 1976). Bugs collected in the first three batches were killed and stored by freezing within a few hours of capture
