Prevalence of gastrointestinal parasites of stray dogs impounded by the Society for the Prevention of Cruelty to Animals (SPCA), Durban and Coast, South Africa

Coprological examination was used to determine the prevalence and intensity of gastrointestinal parasites of stray dogs impounded by the Society for the Prevention of Cruelty to Animals (SPCA), Durban and Coast, South Africa. Helminth and protozoan parasites were found in faeces of 240 dogs with an overall prevalence of 82.5 % (helminth parasites 93.1 % and protozoan parasites 6.9 %). The following parasites and their prevalences were detected; Ancylostoma sp. (53.8 %), Trichuris vulpis (7.9 %), Spirocerca lupi (5.4 %), Toxocara can is (7.9 %), Toxascaris leonina (0.4 %)Giardia intestinalis (5.6 %) and Isospora sp. (1.3 %). Dogs harbouring a single parasite species were more common (41.7 %) than those harbouring 2 (15 %) or multiple (2.1 %) species. Ancylostoma sp., Toxocara canis and Giardia intestinalis have zoonotic potential and were detected in 66.7 % of the samples.
