Abstract

Gastrointestinal helminths, including cestodes and nematodes, represent significant health and economic challenges to the poultry industry due to their pathogenic impact on chickens. Despite the substantial risks they pose, limited research has focused on these parasitic infections. Therefore, a cross-sectional study was conducted from July 2023 to June 2024 in the South Gondar zone to determine the prevalence, distribution, and identify the parasitic gastrointestinal helminthes in chickens. A total of 418 chickens were randomly selected from study districts and subjected to faecal examinations (faecal flotation technique), while 21 chickens from positive cases were selected for post-mortem examination. Both egg morphology and adult parasite identification were employed to identify gastrointestinal helminth species. This study revealed that 289 (69.1 %) of chickens were infected by gastrointestinal helminth parasites. Of these, 141 (33.7 %) were cestodes, 110 (26.3 %) nematodes, and 38 (9 %) mixed infections respectively. The primary cestode species identified were Raillietina tetragona (15.7 %) and Davainea proglottina (10.5 %), and for nematodes, the predominant species were Ascaridia galli (20.8 %), Heterakis gallinarum (12.4 %), and Capillaria annulata (0.4 %). The significant associations were observed concerning age, breed, agroecology, district, and management practices (P < 0.05). However, no significant associations were found between parasite prevalence and the chickens' sex (P > 0.05). These findings highlight the high prevalence of helminth infections as a major challenge for chickens raised in extensive farming systems within the South Gondar zone, underscoring the imperative need for effective control strategies recommended.

鸡胃肠道蠕虫寄生虫：在埃塞俄比亚西北部贡达尔南部地区的流行病学、空间分布和形态解剖学物种鉴定

胃肠道蠕虫，包括蛔虫和线虫，由于它们对鸡的致病性影响，对家禽业构成了重大的健康和经济挑战。尽管它们带来了巨大的风险，但对这些寄生虫感染的研究有限。因此，我们于2023年7月至2024年6月在南贡达尔地区进行了一项横断面研究，以确定鸡胃肠道寄生虫的流行、分布和鉴定。从研究区随机选取418只鸡进行粪便检查（粪便漂浮技术），同时从阳性病例中选取21只鸡进行死后检查。采用卵形态和成虫鉴定两种方法对胃肠道蠕虫进行鉴定。本研究发现289只鸡（69.1%）感染了胃肠道寄生虫。其中，绦虫141例（33.7%），线虫110例（26.3%），混合感染38例（9%）。主要虫种为长尾虫（15.7%）和长尾虫（10.5%），线虫优势种为鸡蛔虫（20.8%）、鸡异虫（12.4%）和环毛细虫（0.4%）。在年龄、品种、农业生态、地区和管理措施方面观察到显著相关性(P <；0.05)。然而，寄生虫患病率与鸡的性别之间没有显著的相关性(P >；0.05)。这些发现突出表明，蠕虫感染的高流行率是南贡达尔地区粗养养殖系统中饲养的鸡面临的主要挑战，强调迫切需要所建议的有效控制战略。

期刊介绍： Veterinary Parasitology: Regional Studies and Reports focuses on aspects of veterinary parasitology that are of regional concern, which is especially important in this era of climate change and the rapid and often unconstrained travel of people and animals. Relative to regions, this journal will accept papers of the highest quality dealing with all aspects of disease prevention, pathology, treatment, epidemiology, and control of parasites within the field of veterinary medicine. Also, case reports will be considered as they add to information related to local disease and its control; such papers must be concise and represent appropriate medical intervention. Papers on veterinary parasitology from wildlife species are acceptable, but only if they relate to the practice of veterinary medicine. Studies on vector-borne bacterial and viral agents are suitable, but only if the paper deals with vector transmission of these organisms to domesticated animals. Studies dealing with parasite control by means of natural products, both in vivo and in vitro, are more suited for one of the many journals that now specialize in papers of this type. However, due to the regional nature of much of this research, submissions may be considered based upon a case being made by the author(s) to the Editor. Circumstances relating to animal experimentation must meet the International Guiding Principles for Biomedical Research Involving Animals as issued by the Council for International Organizations of Medical Sciences (obtainable from: Executive Secretary C.I.O.M.S., c/o W.H.O., Via Appia, CH-1211 Geneva 27, Switzerland).
