- Abstract
The new legislative framework on Animal Welfare brought increased responsibilities to municipal shelters, in particular in the collection of stray dogs, their sterilization and future adoption. These centers quickly became overcrowded, leading to high parasitism environmental contamination, to the easy spread of parasitic infections and to increased risks to public health. The prevalence of intestinal parasites was evaluated by examination of dog faecal sample, in the municipal control animal centre of Guimarães (north Portugal), identifying risk factors and transmission to man. The overall prevalence of gastrointestinal helminths was 57.2% (95% confidence interval 41.3–71.9%) and observed helminths of the gastrointestinal tract were recorded: Ancylostoma caninum (33%), Toxocara canis (29%), Dipylidium caninum (6%), Capillaria spp. (3%), Trichuris vulpis (1.66%). It is important to point out that young dogs were significantly infected more frequently (p ≤ 0.1) than non-sterilized females and the higher occurrence of nematode infection occurred at the new arrival of stray dogs, in the third collection. With impact on public health, the higher prevalence (p ≤ 0.1) of T. canis in young dogs suggests the existence of real risk for human infection and demonstrate the necessity for a parasite control programme reinforcement at the municipal dog shelter.
