An epidemiological study of gastrointestinal helminths of dogs (Canis familiaris) in two veterinary clinics in Ibadan, Nigeria, was conducted between January 2001 and December 2002. Faecal samples collected from 959 dogs were processed by modified Kato-Katz technique and then examined for helminth eggs. The results of the study showed that 237 (24.7%) of the dogs examined were infected with different types of helminths. The prevalences for the various helminth eggs observed were: Toxocara canis 9.0%, Ancylostoma spp. 17.9%, Toxascaris leonina 0.6%, Trichuris vulpis 0.5%, Uncinaria stenocephala 0.4% and Dipylidium caninum 0.2%. The faecal egg intensities, determined as mean egg count/gram of faeces ( +/- SEM), were: T. canis 462.0 +/- 100.5, Ancylostoma spp. 54.1 +/- 8.6, T. leonina 0.8 +/- 0.4, T. vulpis 0.1 +/- 0.0, U. stenocephala 1.0 +/- 0.7 and D. caninum 0.2 +/- 0.1. Host age was found to be a significant factor with respect to the prevalence and intensity of T. canis and Ancylostoma spp. There was no significant difference in the prevalence of intestinal helminth parasites between male (27.0%) and female (22.5%) dogs (P>0.05). The prevalence of helminth parasites was significantly higher (P < 0.05) in the local breed (African shepherd) (41.2%) than in Alsatian dogs (16.2%) or in other exotic breeds (21.0%). Single parasite infections (85.7%) were more common than mixed infections (3.5%).
2001年1月至2002年12月期间，在尼日利亚伊巴丹的两家兽医诊所对犬（犬科动物）胃肠道蠕虫进行了一项流行病学研究。从959只犬采集的粪便样本采用改良加藤厚涂片法进行处理，然后检查蠕虫虫卵。研究结果显示，接受检查的犬中有237只（24.7%）感染了不同类型的蠕虫。观察到的各种蠕虫虫卵的感染率分别为：犬弓首蛔虫9.0%，钩口线虫属17.9%，狮弓蛔虫0.6%，狐毛首线虫0.5%，窄头钩虫0.4%，犬复孔绦虫0.2%。粪便虫卵强度以每克粪便的平均虫卵数（±标准误）表示，分别为：犬弓首蛔虫462.0±100.5，钩口线虫属54.1±8.6，狮弓蛔虫0.8±0.4，狐毛首线虫0.1±0.0，窄头钩虫1.0±0.7，犬复孔绦虫0.2±0.1。发现宿主年龄是影响犬弓首蛔虫和钩口线虫属感染率及感染强度的一个重要因素。雄性犬（27.0%）和雌性犬（22.5%）肠道蠕虫寄生虫感染率无显著差异（P>0.05）。本地品种（非洲牧羊犬）的蠕虫寄生虫感染率（41.2%）显著高于阿尔萨斯犬（16.2%）或其他外来品种（21.0%）（P<0.05）。单一寄生虫感染（85.7%）比混合感染（3.5%）更常见。
