摘要

The intestine of a Formosan millipede species, Trigoniulus corallinus, was noted to be heavily infected with gregarine parasites. Millipedes used in this study were randomly collected from Shoushan, Kaohsiung from April 1999 to October 2002. Among 63 millipedes examined, our results showed that the total prevalence rate for cephaline gregarines was 87.30%. The infection in the male millipedes (91.67%) was higher than that in the females (84.67%). In some cases, more than two species of different gregarines were found to have simultaneously parasitized a single millipede. Distribution of gregarines was more concentrated in the anterior and middle parts of the intestine than in the posterior part. The predominant form observed in the millipede's intestine was free sporadins. The shape, size, and movement of these gregarines are described. This is the first report of the occurrence of gregarines as intestinal parasites in T. corallinus in Taiwan.

本研究針對磚紅厚甲馬陸（Trigoniulus corallinus）腸道內寄生的簇蟲進行調查，所有馬陸均為1999年4月至2002年10月自高雄壽山地區以隨機方式採得。在所檢查的63隻馬陸中，總感染率為87.30%，雄馬陸的感染率（91.67%）高於雌馬陸的感染率（84.67%）。能寄生在磚紅厚甲馬陸腸內的簇蟲可能多達七種，且在同一隻馬陸個體的腸道中可同時被至少兩種以上不同的簇蟲所寄生。簇蟲在馬陸腸道中並非平均分佈，出現於前段與中段的數目遠遠大於後段。馬陸體內出現的簇蟲以在腸中自由游動的sporadin為最多，研究中即以此時期簇蟲的形狀、大小及運動情形作觀察比較。本研究為在台灣磚紅厚甲馬陸腸道寄生簇蟲的第一篇報告。
