An investigation of helminths in the Norway (brown) rat, Rattus norvegicus, and roof rat, Rattus rattus, from Chiang Mai Moat during May to August 1995, was done. Thirty-three out of thirty-eight trapped rats were infected (86.84%); 16 R. norvegicus (100%) and 17/22 R. rattus (77.27%). The rat was infected with 10 helminth species: 4 trematodes, Centrocestus sp (2.63%), Echinostoma ilocanum (10.52%), Echinostoma malayanum (10.52%) and Quinqueseralis quinqueseralis (39.47%); 2 cestodes, Raillietina sp (36.64%) and Taenia sp (cysticercus) (7.89%); and 4 nematodes, Angiostrongylus cantonensis (42.10%). Nippostrongylus sp (34.21%), Rictularia sp (52.63%) and egg of Capillaria hepatica (7.89%). The helminths were found in the small intestine (84.21%), large intestine (42.10%), lung (36.64%), stomach (28.94%), heart (23.94%), and liver (15.78%). The female Norway rats were infected with 10 species of helminths and the males with 6 species. In the roof rat, 7 species of helminths were found in females and 6 species in males.
1995年5月至8月期间，对清迈护城河的挪威（褐）鼠（Rattus norvegicus）和屋顶鼠（Rattus rattus）体内的蠕虫进行了调查。在捕获的38只老鼠中，有33只受到感染（86.84%）；16只挪威鼠（100%）和22只屋顶鼠中的17只（77.27%）。老鼠感染了10种蠕虫：4种吸虫，分别是棘口属吸虫（Centrocestus sp，2.63%）、伊族棘口吸虫（Echinostoma ilocanum，10.52%）、马来亚棘口吸虫（Echinostoma malayanum，10.52%）和五口吸虫（Quinqueseralis quinqueseralis，39.47%）；2种绦虫，分别是瑞列绦虫（Raillietina sp，36.64%）和带绦虫（Taenia sp，囊尾蚴，7.89%）；以及4种线虫，分别是广州管圆线虫（Angiostrongylus cantonensis，42.10%）、类圆线虫属（Nippostrongylus sp，34.21%）、瑞氏线虫属（Rictularia sp，52.63%）和肝毛细线虫卵（Capillaria hepatica，7.89%）。这些蠕虫在小肠（84.21%）、大肠（42.10%）、肺（36.64%）、胃（28.94%）、心脏（23.94%）和肝脏（15.78%）中被发现。雌性挪威鼠感染了10种蠕虫，雄性感染了6种。在屋顶鼠中，雌性发现7种蠕虫，雄性发现6种。
