Abstract: | The present study is the first report that describes the national survey of intestinal parasites in private household dogs
brought to veterinary clinics in Japan. A total of 2,365 fresh feces were collected. Giardia-specific coproantigen was examined by ELISA kit (SNAP?
Giardia, IDEXX Laboratories, Inc.; Maine, USA). Other intestinal parasites were determined microscopically using the formalin–ethyl
acetate sedimentation technique. According to age categories, Giardia duodenalis, Cystoisospora spp., Toxocara canis, Toxascaris leonina, and Strongyloides spp., at ≦6-months-old showed significantly (P < 0.0001, P < 0.001 or P < 0.01, respectively) higher prevalence compared to >6 months old (31.5% vs. 2.3%, 9.1% vs. 0.05%, 1.8% vs. 0.4%, 1.1% vs.
0%, and 1.1% vs. 0.05%, respectively). In clinical categories, prevalences of G. duodenalis (14.8%) and Cystoisospora spp. (4.7%) in symptomatic dogs were significantly (P < 0.05, respectively) higher than those in asymptomatic ones (7.9% and 1.6%, respectively). G. duodenalis and Cystoisospora spp. were dominant parasites in private household dogs in Japan, especially ≦6-month-old dogs. |
