Rodent species, such as Rattus rattus diardii and Rattus norvegicus are invasive species of wild rats that serve as potential reservoirs of important human's pathogens. Parasitic zoonosis accounts for over 60% of all human infectious diseases worldwide. This situation arises from the recent changes in the global climate and ecosystem composition, which led to the spread of rodents and rodent-borne pathogens globally. The aim of this study was to determine the occurrence of rodent's parasites and their zoonotic potentials in some selected areas in UPM. Rodents were captured using live-traps and euthanised for helminths and protozoan recovery. Intestinal parasites were detected and identified from stool samples using formalin ethyl-acetate concentration technique (FECT), while tissue parasites were identified by histopathological examination of selected tissue sections of the liver, brain, lungs, and muscle. In this study, a total of 89 wild rats were captured. Twelve species of intestinal and tissue parasites were recorded, of which, Taenia taeniaeformis accounts for the highest infection recorded (28%) followed by Hymenolepis nana (19.5%) and Capillaria hepatica (19.1%), while Toxoplasma gondii was the least parasite (6.7%) identified. Furthermore, other parasites species observed include, Cryptosporidium spp. (21.3%), Entamoeba histolytica/Entamoeba dispar and Moniliformis moniliformis (17.9%), Angiostrongylus cantonensis (16.8%), Hymenolepis diminuta (16.1%), Giardia spp. (14.6%), Trichuris spp. (12.3%), and Sarcocystis spp. (6.74). Based on the results obtained in the present study, 17.1% and 15.4% of the rodents captured were confirmed positive for at least one species of intestinal or tissue parasites, respectively. The presence of these zoonotic parasites in the wild rats suggests the potential risk of rodent-borne zoonotic disease transmission to humans. Hence, the need to improved rats control intervention and public health awareness among the populace.

马来西亚雪兰莪沙登野鼠啮齿动物传播的寄生虫病原体的检测:对人类健康的潜在威胁。

啮齿类动物,例如黄家鼠和褐家鼠,是野鼠的入侵物种,是人类重要病原体的潜在储存库。人畜共患寄生虫病占全世界所有人类传染病的 60% 以上。这种情况源于最近全球气候和生态系统组成的变化,导致啮齿动物和啮齿动物传播的病原体在全球范围内传播。本研究的目的是确定芬欧汇川大学某些选定区域中啮齿动物寄生虫的发生情况及其人畜共患的可能性。使用活体陷阱捕获啮齿动物并对其实施安乐死,以恢复蠕虫和原生动物。使用福尔马林乙酸乙酯浓缩技术(FECT)从粪便样本中检测和鉴定肠道寄生虫,而通过对肝脏、脑、肺和肌肉的选定组织切片进行组织病理学检查来鉴定组织寄生虫。本次研究共捕获89只野鼠。记录了 12 种肠道和组织寄生虫,其中,带状带绦虫感染率最高(28%),其次是膜皮虫(19.5%)和肝毛细虫(19.1%),而弓形虫感染率最低(6.7%)。 %)确定。此外,观察到的其他寄生虫种类包括隐孢子虫属。(21.3%)、溶组织内阿米巴/迪斯帕内阿米巴和念珠菌 (17.9%)、广州管圆线虫 (16.8%)、Hymenolepis diminuta (16.1%)、贾第鞭毛虫 (16.1%)。(14.6%),鞭虫属。(12.3%) 和肉孢子虫属。(6.74)。根据本研究获得的结果,分别有 17.1% 和 15.4% 的捕获啮齿动物被证实对至少一种肠道或组织寄生虫呈阳性。野鼠身上存在这些人畜共患寄生虫,表明啮齿动物传播的人畜共患疾病存在传播给人类的潜在风险。因此,需要提高公众的老鼠控制干预措施和公共卫生意识。
