Prevalence of intestinal parasites in shelter dogs and cats in the metropolitan area of Barcelona (Spain)

Abstract

Prevalence of intestinal parasites in dogs and cats in Barcelona and surrounding areas was studied by analyzing 505 faecal samples of dogs and 50 of cats using a formol-ether diphasic method for helminths, a modified acid-fast technique for Cryptosporidium and other coccidian oocysts, and the Heindenhein technique for Giardia and Entamoeba trophozoites and cysts. Parasites were found in 26.9% of dogs and 34.0% of cats. Giardia duodenalis, Cryptosporidium sp., coccidian oocysts and Entamoeba sp. were detected in both dogs and cats. Taenia sp., Dipylidium caninum, Ancylostoma caninum, Toxocara canis, Toxascaris leonina, Trichuris vulpis and Uncinaria sp. were also found in dogs but only Ancylostoma tubaeforme and Toxocara cati in cats. There was a significant relationship for G. duodenalis and Cryptosporidium sp. with seasonality and for G. duodenalis with geographical origin in dogs. Significant differences were also found for T. canis between stray and domestic dogs and for T. vulpis between males and females. © 2009 Versita Warsaw and Springer-Verlag Berlin Heidelberg.
