The prevalence of canine intestinal parasitism was evaluated by fecal examination of 4,058 dogs admitted to the Louisiana State University Veterinary Teaching Hospital and Clinics from March 1977 to March 1980). One or more species of parasites was identified in 2,048 (50.5%) dogs. Hookworms were encountered in 38.5% of the dogs examined, whipworms in 14.9%, ascarids in 8.5%, coccidia in 2.6%, tapeworms in 2.2%, and giardia in 0.8%. Single parasitic infection was present in 1,456 (35.9%) dogs. For hookworm and whipworm infections, male dogs were significantly (P less than .05) more often affected, compared with females or spayed females. Ascarid, coccidia, and giardia infections were more prevalent in pups than in mature dogs, whereas whipworm infections were detected less often in dogs less than 6 months of age. Hookworms were the most prevalent parasites in male (39.2%) and female (35.7%) dogs less than 6 months of age and maintained high prevalence in mature dogs. Tapeworm infections were diagnosed sporadically in all age groups. In female dogs greater than 24 months of age, significantly less parasitism was present as compared with younger females. In male dogs, the prevalence of parasitism diminished less markedly with increasing age.
通过对1977年3月至1980年3月期间入住路易斯安那州立大学兽医教学医院及诊所的4058只犬进行粪便检查，评估犬肠道寄生虫感染率。在2048只（50.5%）犬中鉴定出一种或多种寄生虫。在所检查的犬中，钩虫感染率为38.5%，鞭虫为14.9%，蛔虫为8.5%，球虫为2.6%，绦虫为2.2%，贾第虫为0.8%。1456只（35.9%）犬存在单一寄生虫感染。对于钩虫和鞭虫感染，雄性犬比雌性犬或绝育雌性犬受影响的频率显著更高（P小于0.05）。蛔虫、球虫和贾第虫感染在幼犬中比成年犬更普遍，而鞭虫感染在6月龄以下的犬中检出频率较低。钩虫是6月龄以下雄性（39.2%）和雌性（35.7%）犬中最常见的寄生虫，在成年犬中也保持较高感染率。绦虫感染在所有年龄组中均偶有诊断。在24月龄以上的雌性犬中，与年轻雌性犬相比，寄生虫感染明显较少。在雄性犬中，寄生虫感染率随年龄增长下降不太明显。
