目的:许多鱼类可以在其组织中携带多种病原体。在许多病原体中,球藻属的寄生线虫,它存在于鱼类的组织中,会导致人类的鱼源感染。这项研究计划评估消费者对Chamo湖捕鱼地点鱼类传播的人畜共患病的认识,ArbaMinch,埃塞俄比亚。该研究还旨在证明人畜共患线虫,从查莫湖收集的尼罗罗非鱼和Latesniloticus鱼类中的梭菌寄生虫,ArbaMinch,埃塞俄比亚。
结果:通过结构化和半结构化问卷进行面对面访谈,对随机选择的参与者(n=162)进行了对鱼源性人畜共患病意识的评估。此外,70条鱼(O.通过标准解剖检查了niloticus=35和L.niloticus=35)是否存在吸食科和其他anisakid属的幼虫,胃蛋白酶-盐酸消解及显微观察。根据他们对问题的回答,消费者对鱼类传播的人畜共患病的认识不足。大多数受访者(82%)在该地区食用生鱼。其中,男性比例明显更高(p<0.001),完成他们的小学或高中(p=0.004),东正教徒(p=0.044),渔民(p<0.001)和以前没有关于鱼源性人畜共患病信息的参与者(p<0.001)。总的来说,被检查的鱼类(n=70),n=15(21.4%,95%CI,12.8-33.2)感染了梭菌幼虫。尼罗氏乳球菌的感染率显着(p=0.028)较高(34.3%,95%CI,19.7-52.3)与O.niloticus(8.6%,95%CI,2.2-24.2)。在鱼的总重量中添加单位克会显著增加1%(p<0.001)感染的风险。
结论:卷柏的存在,鱼类中的人畜共患线虫,消费者通常喜欢生菜,指出该地区可能存在鱼类传播感染的高风险。因此,为渔民提供教育和培训,该地区的游客,和当地人来这里吃鱼,将风险降到最低是不可避免的重要。此外,卫生工作者应该怀疑鱼源感染,例如,在ArbaMinch有生鱼食用史的患者中,埃塞俄比亚。
OBJECTIVE: Many fish species can harbour a wide range of pathogenic agents in their tissues. Of many pathogens, the parasitic nematode of genus Contracaecum, which resides in the tissues of fish species, can results in fish-borne infections in humans. This study was planned to assess consumers\' awareness of fish-borne zoonoses in the fishing sites of Lake Chamo, Arba Minch, Ethiopia. The study was also aimed at demonstrating the zoonotic nematode, Contracaecum parasites in the Oreochromis niloticus and Lates niloticus fishes collected from Lake Chamo, Arba Minch, Ethiopia.
RESULTS: Assessment of awareness about fish-borne zoonoses was conducted in randomly selected participants (n = 162) using face-to-face interviews via a structured and semi-structured questionnaire. Besides, 70 fishes (O. niloticus = 35 and L. niloticus = 35) were examined for the presence of larva of Contracaecum and other anisakid genera through standard dissection, pepsin-hydrochloric acid digestion and microscopic observation. Consumers have inadequate awareness about fish-borne zoonoses based on the answers they provided to the questions. The majority of respondents (82%) consume raw fish in the area. Of these, a significantly higher proportion were male (p < 0.001), completed their elementary or high school (p = 0.004), Orthodox Christian (p = 0.044), fishermen (p < 0.001) and participants without previous information about fish-borne zoonoses (p < 0.001). Overall, of examined fishes (n = 70), n = 15 (21.4%, 95% CI, 12.8-33.2) were infected with Contracaecum larva. A significant (p = 0.028) higher infection prevalence was noted in L. niloticus (34.3%, 95% CI, 19.7-52.3) compared to O. niloticus (8.6%, 95% CI, 2.2-24.2). A unit gram addition in the total weight of fish would significantly raise the risk of Contracaecum infection by 1% (p < 0.001).
CONCLUSIONS: The presence of Contracaecum, a zoonotic nematode in the fishes, which are often preferred by consumers for raw dishes, designates a high risk of possible fish-borne infections in the area. Thus, providing education and training for fishermen, visitors of the area, and local people who visit the area for fish consumption, it is inevitably important to minimize the risk. Furthermore, health workers should suspect fish-borne infections, such as anisakidosis in patients who have a history of raw fish consumption in Arba Minch, Ethiopia.
