This study aimed to investigate intestinal helminth infection in stray dogs in Osaka Prefecture, by surveying coprological samples from dogs captured from 2006–2011. Of 212 fecal samples collected, overall prevalence of infection was 39.2%. The most common species was Toxocara canis (25.0%), followed by Trichuris vulpis (8.0%), Spirometra erinaceieuropaei (3.3%), Taeniidae (2.4%), Ancylostoma caninum (1.9%) and Toxascaris leonina (0.5%). In the molecular analysis, all of the taeniid eggs were negative for Echinococcus multilocularis and were identified as other taeniid species (e.g., Taenia pisiformis). Our results suggest that stray dogs remain important infection reservoirs of zoonotic parasites in Osaka Prefecture. Therefore, control of stray dogs is crucial for reducing the risk of public health problems due to parasitic infections.
