Resumen

CRUZ T, Lilian et al. Gastrointestinal helminths in sheepdogs in farmers communities of Puno, Peru. Rev. investig. vet. Perú [online]. 2012, vol.23, n.1, pp. 72-79. ISSN 1609-9117.

The frequency of gastrointestinal helminths in sheepdogs of Ajoyani and Macusani districts in the province of Carabaya, and in the districts of Ocuvíri, Palca, Lampa, and Santa Lucía in the province of Lampa, Puno, Peru was determined. Stool samples were collected from 352 crossbreed dogs, mostly adults and apparently healthy, during January to March 2008. The coproparasitological evaluation was done by the methods of flotation with sugar solution or Sheather’s, and by the spontaneous sedimentation technique. Samples were preserved in both 10% formaldehyde and 2.5% bichromate. The resulted showed 20.5 ± 4.2% of dogs were infected with gastrointestinal helminthes. The frequency of dogs with eggs of Taenia was 14.5 ± 3.7%, Trichuris vulpis was 2.6 ± 1.7%, Capillaria sp was 0.9 ± 1%, while for Toxocara canis, Toxascaris leonina, and Ancylostoma sp was 1.4 ± 1.2% each. Besides, the frecuency of Sarcocystis sp was 9.1 ± 3%, Entamoeba coli was 16.5 ± 3.9%, and Isospora sp was 11.9 ± 3.4%. Age, sex, and agro-climatic zone were not considered risk factors for gastrointestinal parasitism. Monoparasitism occurred in 90.9% of dogs with parasite infections. Analysis of samples preserved with 10% formaldehyde or 2.5% bichromate showed similar results and therefore both substances were considered moderately consistent and mutually replaceable according to the Kappa and Mc Nemar tests.
