The prevalence of helminth species in stray dogs, from the capital city of the state of Queretaro, was evaluated. A total of 378 dogs were captured and examined for the presence of helminths from January to December 2008. The results showed that 275 (72.8%) of examined dogs were infected with one or more helminth species. Single infections were observed in 139 (50.5%) of infected dogs and 136 (49.5%) harboured mixed infections. Out of the 378 dogs examined, 208 (55.2%) presented nematodes and 182 (48.1%) cestodes. The prevalences (confidence interval) and mean intensities of infection ( ± SD) of nematodes and cestodes encountered were: Ancylostoma caninum 42.9% (37.9-47.8) and 22.1 ( ± 34.3); Toxocara canis 15.1% (11.8-19.0) and 8.3 ( ± 15.0); Spirocerca lupi 4.5% (2.7-7.1) and 3.9 ( ± 4.8); Toxascaris leonina 2.3% (1.1-4.5) and 4.8 ( ± 3.5); Physaloptera praeputialis 1.9% (0.8-3.8) and 9.7 ( ± 14.9); Dirofilaria immitis 1.3% (0.4-3.1) and 5.6 ( ± 2.1); Oslerus osleri 0.3% (0.0-1.6) and 5 ( ± 0.0); Dipylidium caninum 44.9% (40.0-50.0) and 18.1 ( ± 27.7); Taenia spp. 6.9% (4.7-9.9) and 6.9 ( ± 7.1). There were no significant differences in prevalences observed either between female (68.5%) and male (76.8%) or between young (70.6%) and adult (74.2%) animals. No differences were observed in the ANOVA test for the mean intensity of infection of any of the parasites (P>0.05).
对克雷塔罗州首府流浪狗体内蠕虫种类的流行情况进行了评估。2008年1月至12月，共捕获378只狗并检查是否存在蠕虫。结果显示，275只（72.8%）受检狗感染了一种或多种蠕虫。在139只（50.5%）感染狗中观察到单一感染，136只（49.5%）有混合感染。在378只受检狗中，208只（55.2%）有线虫感染，182只（48.1%）有绦虫感染。所遇到的线虫和绦虫的流行率（置信区间）及平均感染强度（±标准差）分别为：犬钩虫42.9%（37.9 - 47.8）和22.1（±34.3）；犬弓首蛔虫15.1%（11.8 - 19.0）和8.3（±15.0）；狼旋尾线虫4.5%（2.7 - 7.1）和3.9（±4.8）；狮弓蛔虫2.3%（1.1 - 4.5）和4.8（±3.5）；阴茎泡翼线虫1.9%（0.8 - 3.8）和9.7（±14.9）；犬恶丝虫1.3%（0.4 - 3.1）和5.6（±2.1）；欧氏奥斯特线虫0.3%（0.0 - 1.6）和5（±0.0）；犬复孔绦虫44.9%（40.0 - 50.0）和18.1（±27.7）；带绦虫属6.9%（4.7 - 9.9）和6.9（±7.1）。在雌性（68.5%）和雄性（76.8%）之间或幼年（70.6%）和成年（74.2%）动物之间观察到的流行率没有显著差异。在对任何一种寄生虫的平均感染强度进行的方差分析中未观察到差异（P>0.05）。
