Standard centrifugal flotation tests and an ELISA were performed to detect 5 common intestinal parasites (roundworms, hookworms, whipworms, <jats:italic>Giardia<\/jats:italic> spp, and <jats:italic>Cystoisospora<\/jats:italic> spp). Group comparisons were performed by means of the \u03c7<jats:sup>2<\/jats:sup> test and Rogan-Gladen prevalence estimate.<\/jats:p>\n<jats:p><jats:bold>RESULTS<\/jats:bold> At least 1 of the 5 evaluated parasites was detected in 85 (45.2%) fecal specimens from AFR shelter dogs and 24 (13.7%) specimens from owned pet dogs. This prevalence differed significantly between the groups. Notably, the prevalence of <jats:italic>Giardia<\/jats:italic> spp in AFR shelter dogs (n = 76 [40.4%]) was higher than previously reported in the United States.<\/jats:p>\n<jats:p><jats:bold>CONCLUSIONS AND CLINICAL RELEVANCE<\/jats:bold> The prevalence of the evaluated intestinal parasites, particularly of <jats:italic>Giardia<\/jats:italic> spp, in AFR shelter dogs was higher than expected. This information is important for veterinarians, animal shelter personnel, pet owners, human health-care providers, and public health officials to consider when devising effective interventions and risk communication efforts against potential zoonotic threats, particularly those relevant to the Phoenix metropolitan area.<\/jats:p>","DOI":"10.2460\/javma.251.5.539","type":"journal-article","created":{"date-parts":[[2017,8,22]],"date-time":"2017-08-22T12:24:46Z","timestamp":1503404686000},"page":"539-543","source":"Crossref","is-referenced-by-count":5,"title":["Survey
