American cockroach () has been implicated as mechanical vector of parasites of humans and animals. Therefore, this study aimed to identify and determine the prevalence of human intestinal parasites associated with the body surface and gut of . A total of 221 cockroaches which include 104 males and 117 females were collected from household kitchen, toilet area and canteen after which they were brought to laboratory for study. The body surface of the cockroach was washed with 5 ml normal saline solution to remove external parasites on the body surface for examination and later rinsed with 70% alcohol and dried before dissecting. The cockroach was dissected to examine internal parasites. Eleven parasites were recovered and identified, these include (51.58%), (48.42%) (52.49%), (.10%), spp (14.93%), (31.67%), spp (34.84%), (53.39%), and (66.23%) (66.52%). The parasites were recorded both on the body surface and gut of the cockroach. There is no significant difference ( > 0.05) between parasites infection rate comparing both sexes; though, female cockroach having a higher infection rate (91.45%) than male (81.5%). Cockroach collected from toilets carried more parasites (96.34%) as compared to those from restaurants/canteen (89.71%) and household kitchens (81.69%). All parasites encountered were pathogenic to human and animals. This study has revealed that can act as mechanical vector by transporting and transmitting these parasites easily to man and animal. Good sanitary practices, reinforcement of worms' eradication programs, and the fight against these insects remain a necessity to contain the menace of parasites burden and cockroach control.
美洲大蠊（）被认为是人类和动物寄生虫的机械传播媒介。因此，本研究旨在鉴定并确定与美洲大蠊体表和肠道相关的人体肠道寄生虫的流行情况。总共从家庭厨房、卫生间区域和食堂收集了221只蟑螂，其中包括104只雄性和117只雌性，之后将它们带回实验室进行研究。用5毫升生理盐水冲洗蟑螂体表以去除体表的外部寄生虫用于检查，随后用70%酒精冲洗并干燥后进行解剖。解剖蟑螂以检查内部寄生虫。共发现并鉴定出11种寄生虫，包括（51.58%）、（48.42%）、（52.49%）、（.10%）、 spp（14.93%）、（31.67%）、 spp（34.84%）、（53.39%）以及（66.23%）（66.52%）。这些寄生虫在蟑螂的体表和肠道均有记录。两性之间的寄生虫感染率无显著差异（>0.05）；不过，雌性蟑螂的感染率（91.45%）高于雄性（81.5%）。从卫生间收集的蟑螂携带的寄生虫（96.34%）比从餐馆/食堂（89.71%）和家庭厨房（81.69%）收集的蟑螂更多。所有发现的寄生虫对人类和动物均具有致病性。本研究表明，美洲大蠊可作为机械传播媒介，轻易地将这些寄生虫传播给人类和动物。良好的卫生习惯、加强驱虫计划以及防治这些昆虫仍然是控制寄生虫负担和蟑螂危害的必要措施。
