Contaminación biológica con heces caninas y parásitos intestinales en espacios públicos urbanos en dos ciudades de la Provincia del Chubut: Patagonia Argentina

Abstract

A longitudinal study to determine the presence of intestinal parasites in canine faeces and their relationship with seasonal weather conditions during a year was carried out. 481 fecal canine deposits were collected from 13 public parks in two cities of Chubut Province, Patagonia Argentina. Stools were analyzed by means of Telemann and Willis methods. Weather conditions were daily registered from local stations. The frequency of positive canine faeces to intestinal parasites was found between 34,9% and 51,2% over the studied period and was season independent (p > 0.05). A predominance of helminths over protozoa was detected in all seasons. Frequency of Entamoeba spp. and Nematoda was seasonal dependent (p < 0.05). The finding of Toxocara canis eggs varied from 12,7% in winter to 20,9% in spring. Pathogens to humans such as T. canis, Taenia spp., Uncinaria spp. and Entamoeba spp. were found. Spirocerca spp. and Capillaria spp. have been reported for the first time for this region. dependent (p < 0.05). The finding of Toxocara canis eggs varied from 12,7% in winter to 20,9% in spring.
