Abstract

Gnathostoma spinigerum was found in gastric nodules in 4.1% of 2940 dogs surveyed in northeastern Thailand. The prevalence and worm burden of G. spinigerum exhibited a seasonal fluctuation. The parasites were more abundant in the rainy season and the early winter (August-December) than in the summer (April-March). Most parasites were sexually mature between August and December while immature worms were observed during March and April. The distribution of gnathostomes within the sampled dogs was highly dispersed and few animals were found to harbour more than five worms.

摘要

在泰国东北部接受调查的2940只狗中，4.1%的狗胃结节中发现有棘颚口线虫。棘颚口线虫的感染率和虫负荷呈现季节性波动。雨季和初冬（8月至12月）的寄生虫比夏季（4月至3月）更为丰富。大多数寄生虫在8月至12月间性成熟，而未成熟虫体则在3月和4月间被观察到。样本狗体内颚口线虫的分布高度分散，很少有动物体内寄生超过5条虫。
