Cockroaches have been recognized as mechanical vectors of pathogens that can infest humans or animals. A total of 844 adult cockroaches (436 males and 408 females) were caught. In the laboratory, cockroaches were first washed in saturated salt solution to remove ectoparasites and then rinsed with 70% alcohol, dried, and dissected for endoparasites. An overall transport rate of 47.39% was recorded. Six genera of parasites were identified. These were (33.76%), (11.97%), (6.16%), (4.86%), Hook Worm (4.86%), and (2.73%). The parasites were more recorded on the external surface (54.27%) of cockroaches than in the internal surface (GIT, 38.51%). The same tendency was obtained between sexes with female cockroaches having a higher transport rate (36.69%). Cockroaches caught in toilets carried more parasites (31.99%) as compared to those from kitchens (22.63%) and houses (11.14%). Almost all encountered parasites were recognized as responsible of zoonosis and they can be consequently released in nature by hosts and easily disseminated by cockroaches as mechanical vectors. Sanitary education, reenforcement of worms' eradication programs, and the fight against these insects remain a necessity in the Mélong Subdivision.
蟑螂已被确认为可感染人类或动物的病原体的机械传播媒介。共捕获了844只成年蟑螂（436只雄性和408只雌性）。在实验室中，蟑螂首先在饱和盐溶液中清洗以去除体外寄生虫，然后用70%酒精冲洗、干燥，并解剖以检查体内寄生虫。记录的总体携带率为47.39%。鉴定出了六个寄生虫属。它们分别是（33.76%）、（11.97%）、（6.16%）、（4.86%）、钩虫（4.86%）和（2.73%）。寄生虫在蟑螂体表（54.27%）的记录比体内表面（胃肠道，38.51%）更多。两性之间也有相同的趋势，雌性蟑螂的携带率更高（36.69%）。与厨房（22.63%）和房屋（11.14%）中的蟑螂相比，厕所中捕获的蟑螂携带更多寄生虫（31.99%）。几乎所有发现的寄生虫都被认为是人畜共患病的病原体，因此它们可以由宿主释放到自然界中，并很容易通过蟑螂作为机械传播媒介传播。在梅隆分区，卫生教育、加强驱虫计划以及防治这些昆虫仍然是必要的。
