Bedbugs of the species Cimex hemipterus (F) were collected on four separate occasions from the bedding in the huts of village dwellers in Senegal, West Africa. Hepatitis-B surface antigen (HBSAg) was detected in unengorged nymph and adult bedbugs in each of the first three collections. 3 of 28 such specimens were HBSAg(+) in the first collection and 3 of 17 specimens were positive in the second collection. In the third, 6 of 9 were HBSAg(+) when the bed occupant was known to be HBSAg(+). 2 of these 6 positive insects did not contain human serum proteins. Bedbugs in the fourth collection were captured and kept alive without a blood meal for 30 days. 3 of 89 of these samples were HBSAg(+). These are the highest field infection-rates of hepatitis-B virus reported in any insect species. The bedbug must be considered a potential vector of hepatitis-B virus.
在西非塞内加尔，从村民小屋的床上用品中，分四次采集到了温带臭虫（Cimex hemipterus (F)）。在前三次采集的未吸血若虫和成年臭虫中，均检测到了乙肝表面抗原（HBSAg）。第一次采集的28个此类样本中有3个HBSAg呈阳性，第二次采集的17个样本中有3个呈阳性。第三次采集时，已知睡在床上的人HBSAg呈阳性，9个样本中有6个HBSAg呈阳性。这6个阳性昆虫中有2个不含人血清蛋白。第四次采集的臭虫被捕获并在未进食血液的情况下存活了30天。这些样本中有89个，其中3个HBSAg呈阳性。这是在任何昆虫物种中报告的乙肝病毒最高野外感染率。臭虫必须被视为乙肝病毒的潜在传播媒介。
