[Prevalence of intestinal helminths in dogs from Quindío Province].

Background: Intestinal helminths are pathogens for domestic animals and provide a source of potential infection for humans.

Objectives: The prevalence of intestinal helminths in domestic dogs was determined in a province-wide survey in Quindío Province, Colombia.

Materials And Methods: The sample size was calculated based upon the data of the 2003 antirabies vaccination program in Quindio. Information in the form of an epidemiological questionnaire was provided by dog owners. Fecal samples from dogs were analyzed by Ritchie's concentration method.

Results: Of 324 samples, 67.6% were from purebred dog races and 32.4% were mongrels. A 22.2% prevalence for intestinal helminthes was found. Ancylostoma caninum was the most prevalent parasite (13.9%), followed by Trichuris vulpis (4.3%), Toxocara canis (2.5%), and Strongyloides stercoralis (4.0%). Multiparasite infestations were observed in 2.46% of the dogs.

Conclusion: Presence of parasites was strongly correlated with age and degree of association with the open streets. Control programs are recommended for helminth surveillance in human and canine populations.
