Intestinal parasites commonly infect dogs and can potentially spread to humans globally. Regrettably, numerous dog owners do not give priority to managing their pets' health, often ignoring treatment unless the animal is already ill. Thus, a cross-sectional study was conducted from December 2022 to April 2023 in Gondar town to determine the prevalence of gastrointestinal nematode parasites in dogs and their associated risk factors. A total of 204 dogs stool samples were collected using purposive sampling techniques. Direct fecal smear and flotation techniques were also used to identify the parasite ova. Chi-square and logistic regression were used to analyze the occurrence of the parasite within the risk factors. The overall prevalence of gastrointestinal nematodes in dogs was 47 (23.03 %) from the total 204 dog stool samples. Among these, (9.31 %) was the most gastrointestinal parasite observed followed by , and . The dog positivity in gastrointestinal nematode occurrence had a statically significant association between age, sex, body condition, and housing management ( ≤ 0.05). Female dogs were 4.5 times (COR: 4.55) and young dogs were 3.5 times (COR: 3.5) more likely exposed to these parasites than their respective male and adult dogs. Regarding body condition scores, poor were 6.5 times (COR: 6.55; 95 % CI: 0.06-0.56) and medium was 0.5 times (COR: 1.5; 95 % CI: 0.26-0.9 9) more exposed than their comparable good body conditions. Generally, this finding suggests potential public health hazards associated with low levels of nematode infections in dogs.
肠道寄生虫通常会感染犬类，并有可能在全球范围内传播给人类。遗憾的是，许多狗主人并不重视管理宠物的健康，往往在动物生病之前忽视治疗。因此，2022年12月至2023年4月在贡德尔镇进行了一项横断面研究，以确定犬类胃肠道线虫寄生虫的流行情况及其相关风险因素。使用目的抽样技术共收集了204份犬粪便样本。还采用直接粪便涂片和漂浮技术来鉴定寄生虫卵。卡方检验和逻辑回归用于分析危险因素中寄生虫的发生情况。在总共204份犬粪便样本中，犬类胃肠道线虫的总体患病率为47例（23.03%）。其中，（9.31%）是观察到的最常见的胃肠道寄生虫，其次是 、 和 。犬类胃肠道线虫感染的阳性率在年龄、性别、身体状况和住房管理之间存在统计学上的显著关联（≤0.05）。雌性犬感染这些寄生虫的可能性是雄性犬的4.5倍（校正比值比：4.55），幼犬感染的可能性是成年犬的3.5倍（校正比值比：3.5）。就身体状况评分而言，身体状况差的犬感染的可能性是身体状况良好的犬的6.5倍（校正比值比：6.55；95%置信区间：0.06-0.56），身体状况中等的犬感染的可能性是身体状况良好的犬的0.5倍（校正比值比：1.5；95%置信区间：0.26-0.99）。总体而言，这一发现表明犬类线虫感染水平低可能对公共卫生构成危害。
