A total of 204 rodents comprising 14 host species from four different habitats were examined. Nine rodent species were trapped from the forest and another five species were trapped from the coastal, rice field and urban habitats. Rattus rattus diardii (67%) was the predominant rodent species examined. Fifty six (47.3%) rodents and shrews were found to be infested with at least one of the 20 species of ectoparasite recovered. Mites belonging to the family Trombiculidae were the predominant ectoparasite species recovered. Ticks belonging to the family Ixodidae were recovered mainly from the forest dwelling rodents. Polyplax spinulosa and Hoplopleura pacifica were the common lice species found infesting the urban rodents. Xenopsylla cheopis was the only flea species recovered. The following ecto-parasites have been incriminated as important vectors or as mechanical carriers for the transmission of zoonotic diseases: Ixodes granulatus, Dermacentor sp. Haemaphysalis sp., Amblyomma sp. Ascoschoengastia indica, Leptotrombidium deliense, Ornithonyssus bacoti, Laelaps nuttalli, H. pacifica, P. spinulosa and Xenopsylla cheopis. Urban and forest rodents were significantly higher in ecto-parasitic infestation, compared to rats from the other two habitats. However, there was no significant statistical association between male and female rodents infested with ectoparasites.
共检查了来自四个不同栖息地的204只啮齿动物,它们分属于14个宿主物种。从森林中捕获了9种啮齿动物,另外5种则从沿海、稻田和城市栖息地捕获。黑家鼠(67%)是所检查的主要啮齿动物物种。发现56只(47.3%)啮齿动物和鼩鼱感染了所回收的20种体外寄生虫中的至少一种。恙螨科的螨是所回收的主要体外寄生虫物种。硬蜱科的蜱主要从栖息于森林的啮齿动物身上回收。刺多板虱和太平洋钩鬃虱是在城市啮齿动物身上发现的常见虱类物种。印鼠客蚤是唯一回收的蚤类物种。以下体外寄生虫被认为是重要的媒介或人畜共患病传播的机械传播者:粒形硬蜱、 Dermacentor属、血蜱属、花蜱属、印度囊棒恙螨、地里纤恙螨、柏氏禽刺螨、纳氏厉螨、太平洋钩鬃虱、刺多板虱和印鼠客蚤。与来自其他两个栖息地的老鼠相比,城市和森林啮齿动物的体外寄生虫感染率明显更高。然而,感染体外寄生虫的雄性和雌性啮齿动物之间没有显著的统计学关联。
