A study to determine the diversity and distribution of ectoparasites and endoparasites infesting wild rat population of Carey Island was carried out from June to December 2010. A total of 81 rats were captured from various locations on Carey Island. Four rat species were identified namely, Rattus tiomanicus (45.7%), Rattus rattus diardii (25.9%), Rattus argentiventer (16%) and Rattus norvegicus (12.3%). Low diversity of ecto and endoparasites were observed infecting the rodent population with 8 ecto and 8 endoparasites species recorded. The ectoparasites recovered fell under 3 broad groups, namely mites (Laelaps nuttali, Laelaps echidninus, Laelaps sculpturatus, Listrophoroides sp. and Ornithonyssus bacoti), lice (Polyplax spinulosa and Hoplopleura pacifica) and tick (Ixodes granulatus) while endoparasites recovered were cestodes (Taenia taeniaformis and Hymenolepis diminuta) and nematodes (Nippostrongylus brasiliensis, Angiostrongylus malaysiensis, Mastophorus muris, Heterakis spumosa, Hepatojarakus malayae and Syphacia muris). The rat population was observed harbouring more than one parasite species. Analysis of data also showed neither intrinsic (host age, host sex) nor extrinsic (season) factors influenced the macroparasites community structure.
2010年6月至12月，开展了一项关于确定侵袭凯里岛野生鼠类种群的体外寄生虫和体内寄生虫的多样性及分布情况的研究。从凯里岛的不同地点共捕获了81只老鼠。鉴定出四种鼠类，分别是蒂奥曼鼠（45.7%）、迪氏黑家鼠（25.9%）、银腹鼠（16%）和褐家鼠（12.3%）。观察到感染啮齿动物种群的体外和体内寄生虫多样性较低，共记录到8种体外寄生虫和8种体内寄生虫。回收的体外寄生虫分为三大类，即螨类（纳氏厉螨、棘厉螨、雕刻厉螨、类虱螨属和柏氏禽刺螨）、虱类（多板棘虱和太平额虱）和蜱类（粒形硬蜱），而回收的体内寄生虫有绦虫（泡状带绦虫和微小膜壳绦虫）和线虫（巴西日圆线虫、马来西亚管圆线虫、鼠鞭虫、短膜壳绦虫、马来肝贾拉虫和鼠管状线虫）。观察到鼠类种群感染不止一种寄生虫。数据分析还表明，内在因素（宿主年龄、宿主性别）和外在因素（季节）均未影响大型寄生虫群落结构。
