In total, 414 anophelines, consisting of Anopheles karwari (James), An. splendidus Koidzumi, An. dirus Peyton & Harrison, and An. barbirostris Van der Wulp were collected in 2 provinces in eastern Thailand and tested by enzyme-linked immunosorbent assay for the presence of circumsporozoite proteins. Plasmodium vivax CS protein was detected in 3.4% (2/54) of An. karwari and 4.8% (2/42) of An. barbirostris specimens. Both P. vivax phenotypes, Pv247 and Pv210, were found in An. karwari, whereas only Pv247 was detected in An. barbirostris. Plasmodium falciparum CS protein was detected only in 0.3% (1/276) of An. dirus. Results indicate that An. barbirostris may play a role in the transmission of P. vivax in Chanthaburi Province, Thailand.
在泰国东部的两个省份共采集了414只按蚊，包括卡氏按蚊（詹姆斯按蚊）、华丽按蚊、大劣按蚊和须喙按蚊，并通过酶联免疫吸附测定法检测其环子孢子蛋白的存在情况。在3.4%（2/54）的卡氏按蚊和4.8%（2/42）的须喙按蚊标本中检测到间日疟原虫环子孢子蛋白。在卡氏按蚊中发现了间日疟原虫的两种表型Pv247和Pv210，而在须喙按蚊中仅检测到Pv247。仅在0.3%（1/276）的大劣按蚊中检测到恶性疟原虫环子孢子蛋白。结果表明，须喙按蚊可能在泰国尖竹汶府间日疟原虫的传播中起作用。
