ZARATE R, Daniel; CHAVEZ V, Amanda; CASAS A, Eva  and  FALCON P, Néstor. Prevalencia de Giardia sp. en canes de los distritos del cono sur de Lima Metropolitana. Rev. investig. vet. Perú [online]. 2003, vol.14, n.2, pp.134-139. ISSN 1609-9117.

The object of this study was to assess the prevalence of Giardia sp. in domestic canines from the South esn part of Lima city, Peru. A total of 204 fecal samples from domestic canines of the districts of Surco, Barranco, Chorrillos, San Juan de Miraflores, Villa María del Triunfo and Villa El Salvador were recolected. The animals were stratified according to the socioeconomic level of the owner. Samples were analized by the direct examination test and Spontaneous sedimentation test for detecting Giardia sp. The direct examination test showed 8.8 ± 3.9% (18/204) of positive samples whereas the spontaneous sedimentation gave a prevalence of 15.7 ± 5.0 (32/204). The spontaneous sedimentation technique showed to be more sensible than the direct examination test when results were compared by the McNemar test. The Logistic Regression test failed the show a significative relationship between presence of Giardia sp. and socioeconomic level of the owner or sex of animal. Puppies ( <1 year old) were more susceptibles than adults (³1 year). Likewise, parasitic forms were more frequently detected in soft than in normal feces the results indicated the existence of a moderate prevalence of Giardia sp. infection in canine population of the Southern part of Lima City, suggesting that canine giardiasis in Lima would be a serious problem of Public Health.
