Abstract

Gastrointestinal (GI) parasites in companion animals pose significant veterinary and public health challenges, especially in densely populated urban areas and developing regions such as Dhaka, Bangladesh. Thus, this study was designed to determine the prevalence of GI parasitic infections in pet dogs and cats, identify the parasite species, and analyze the associated risk factors. A cross-sectional survey was conducted from January to June 2024, involving 120 dogs and 197 cats in Dhaka City. Fresh fecal samples were collected from the dogs and cats and analyzed for parasitic eggs, cysts, and oocysts using microscopic methods, including direct smear, fecal flotation, and sedimentation techniques. The results revealed an overall parasitic prevalence of 63.33 % in dogs and 58.37 % in cats, with a total of 15 parasitic species identified in both pets. The presence of both shared and host-specific parasites highlights the risks of environmental contamination, with Toxocara spp. being the most commonly identified parasite in dogs and cats. Among the parasites, Alaria spp., Ancylostoma spp., Ascaris spp., Balantidium coli, Capillaria spp., Entamoeba coli, Schistosoma spp., Spirometra spp., Strongyloides spp., Taenia spp., Toxocara canis/cati, Trichuris spp. can infect humans and have zoonotic transmission potential. The key risk factors identified for dogs include the absence of deworming, male sex, age under one year, and hunting behavior. For cats, the primary significant factors were the absence of deworming and being crossbred. The findings highlight the importance of regular deworming, proper pet management, and strengthened public health measures to mitigate veterinary and public health risks. This study can aid veterinarians and public health authorities in formulating strategies to control gastrointestinal parasitic infections while encouraging pet owners to adopt responsible pet care practices.

孟加拉国达卡市狗和猫胃肠道寄生虫的流行、危险因素和人畜共患意义

伴侣动物的胃肠道寄生虫对兽医和公共卫生构成重大挑战，特别是在人口稠密的城市地区和发展中地区，如孟加拉国的达卡。因此，本研究旨在确定宠物狗和猫胃肠道寄生虫感染的流行情况，确定寄生虫种类，并分析相关危险因素。2024年1月至6月进行了一项横断面调查，涉及达卡市的120只狗和197只猫。从狗和猫身上收集新鲜粪便样本，并使用显微镜方法分析寄生卵、囊肿和卵囊，包括直接涂片、粪便浮选和沉淀技术。结果显示，犬和猫的总体寄生虫患病率分别为63.33%和58.37%，两种宠物共鉴定出15种寄生虫。共有寄生虫和宿主特有寄生虫的存在突出了环境污染的风险，弓形虫是狗和猫中最常见的寄生虫。其中，阿拉氏虫、钩虫、蛔虫、大肠平衡虫、毛细虫、大肠内阿米巴、血吸虫、螺旋体、圆线虫、带绦虫、犬弓形虫、毛虫等寄生虫可感染人类，具有人畜共患的传播潜力。确定的狗的主要风险因素包括没有驱虫、雄性、一岁以下和狩猎行为。对于猫来说，主要的重要因素是没有驱虫和杂交。研究结果强调了定期驱虫、妥善管理宠物以及加强公共卫生措施以减轻兽医和公共卫生风险的重要性。本研究可协助兽医和公共卫生当局制定控制胃肠道寄生虫感染的策略，同时鼓励宠物主人采取负责任的宠物护理措施。

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).
