Birds in a free environment carry huge risk of helminth parasite infections affecting the health of poultry and thereby indirectly leading to great economic loss. The present study aimed to evaluate the prevalence, intensity and species diversity of gastrointestinal helminth parasites (GIH) of country chicken () from local chicken markets of Visakhapatnam district, Andhra Pradesh. A total of 300 gastrointestinal tract (GIT) samples were examined from January to December 2021 and the collected parasites were separated, counted, identified and statistically analysed. The overall prevalence of infection was found to be 87% with an intensity of 139.29. The study showed high prevalence with mixed infections (66%), whereas the prevalence with individual groups i.e. cestodes, nematodes and trematodes was found to be 83.00%, 70.33%, and 0.67% respectively. Altogether 10 parasite species were identified viz. being the most dominant with a prevalence of 72.67%, followed by (62.00%), (59.33%), (45.33%), (43.00%), (42.67%), (38.33%), sp. 1 (36.00%), spp. (29.67%) and the least was sp. 2 (21.00%). In month-wise data, highest prevalence was recorded in July (100%), and the highest seasonal prevalence was recorded in summer (90%), followed by monsoon (87%) and winter (84%). No major significant difference in prevalence was noted between males (88.51%) and females (85.53%). Hosts with high body temperature and low GIT pH levels showed increased prevalence and parasite intensity.
处于自由环境中的鸟类携带大量蠕虫寄生虫感染风险，会影响家禽健康，进而间接导致巨大经济损失。本研究旨在评估来自安得拉邦维沙卡帕特南地区当地鸡肉市场的土鸡胃肠道蠕虫寄生虫（GIH）的感染率、感染强度和物种多样性。2021年1月至12月共检查了300份胃肠道（GIT）样本，对收集到的寄生虫进行分离、计数、鉴定并进行统计分析。总体感染率为87%，感染强度为139.29。研究显示混合感染的患病率较高（66%），而绦虫、线虫和吸虫等单个类别的患病率分别为83.00%、70.33%和0.67%。共鉴定出10种寄生虫，其中最为主要，患病率为72.67%，其次是（62.00%）、（59.33%）、（45.33%）、（43.00%）、（42.67%）、（38.33%）、sp. 1（36.00%）、spp.（29.67%），最少的是sp. 2（21.00%）。按月数据来看，7月的患病率最高（100%），季节患病率最高的是夏季（90%），其次是季风季节（87%）和冬季（84%）。雄性（88.51%）和雌性（85.53%）之间的患病率没有显著差异。体温高且胃肠道pH值低的宿主患病率和寄生虫感染强度增加。
