Abstract

A total of 1,788 livers from swamp eels (Fluta alba), purchased at a market in Bangkok, Thailand, from April to July 2002, were studied for the prevalence and intensity of Gnasthostoma third stage larvae (L3s). Of all livers, 466 were infected with Gnasthostoma L3s (infection rate = 26%). The larvae recovered averaged 0.43 +/- 0.51 larvae/liver. All larvae were identified as Gnasthostoma spinigerm by morphological criteria. The prevalence of G. spinigerum L3s in the eels was much higher in the rainy season (June and July, 74%) than during April and May (8%). Therefore, prevention programs for gnathostomiasis should be emphasized during the rainy season.

摘要

2002年4月至7月，从泰国曼谷一个市场购买了共计1788条黄鳝的肝脏，对其颚口线虫第三期幼虫（L3s）的感染率和感染强度进行了研究。在所有肝脏中，466个感染了颚口线虫L3s（感染率=26%）。回收的幼虫平均为0.43±0.51条/肝脏。所有幼虫均根据形态学标准鉴定为棘颚口线虫。棘颚口线虫L3s在黄鳝中的感染率在雨季（6月和7月，74%）比4月和5月（8%）高得多。因此，应在雨季加强颚口线虫病的预防措施。
