Abstract
Animal ancylostomiasis co-occurs with gastrointestinal and respiratory disorders, emaciation, and developmental delay, and may progress to cachexia and death. A total of 357 fecal samples from stray dogs captured by the Center for Zoonotic Disease Control in Lages, Santa Catarina, Brazil, from June 2011 to January 2012, were assessed by the Willis-Mollay method. The prevalence of positive dogs for Ancylostoma spp. eggs was 64.43% (230/357), affecting 63.16% (120/190) of females and 65.87% (110/167) of males. Animals aged 2 to 5 years showed higher parasite infection rates (77.78%), but no statistical difference was noted between age groups and sex of infected dogs. There was coinfection of Ancylostoma spp. with Trichuris vulpis and Toxocara spp. Summertime revealed a larger significant correlation with Ancylostoma spp. infection. Dogs infected by Ancylostoma spp. were detected in 44 (64.71%) out of 68 neighborhoods. Infected stray dogs are an important source of infection as they roam the streets and public squares. Zoonotic control measures are therefore crucial, mainly on the outskirts, where the number of infected dogs is larger
