总结五口虫寄生虫，Raillietiella frenata，原产于亚洲，在那里它感染了亚洲壁虎，Hemidactylus frenatus。这种壁虎已被广泛引入，最近R。frenata在澳大利亚的甘蔗蟾蜍（Rhinella marina）的引进种群中发现，表明从引进的壁虎到蟾蜍的宿主转换。在这里，我们报告非本地成人R。感染巴拿马本地甘蔗蟾蜍的肺部。64只蟾蜍中有8只被感染（中位数= 2.5，范围= 1-80 pentastomid/蟾蜍），pentastomid患病率与一个地点的建筑物数量呈正相关，但需要进一步取样来证实这种模式。我们推测，这种模式可能是由于主机转移这种寄生虫从城市相关的介绍壁虎。这是第一次记录这种寄生虫感染甘蔗蟾蜍在其原产地，这种寄生虫发生在中美洲的第一个例子。
SUMMARY The pentastomid parasite, Raillietiella frenata, is native to Asia where it infects the Asian House gecko, Hemidactylus frenatus. This gecko has been widely introduced and recently R. frenata was found in introduced populations of cane toads (Rhinella marina) in Australia, indicating a host-switch from introduced geckos to toads. Here we report non-native adult R. frenata infecting the lungs of native cane toads in Panama. Eight of 64 toads were infected (median = 2·5, range = 1–80 pentastomids/toad) and pentastomid prevalence was positively associated with the number of buildings at a site, though further sampling is needed to confirm this pattern. We postulate that this pattern is likely due to a host shift of this parasite from an urban-associated introduced gecko. This is the first record of this parasite infecting cane toads in their native range, and the first instance of this parasite occurring in Central America.
