Principal intestinal parasites of dogs in Tirana, Albania.
From 2004 to 2009, the digestive tracts of 111 dogs from suburban areas around Tirana, Albania, were examined for intestinal helminths. In addition, rectal faecal samples of all dogs were examined for protozoan infections and 48 faecal samples from dogs >6 months of age were processed with the Baermann technique to test for the excretion of lungworm larvae. The heart and pulmonary arteries of 30 dogs >6 months of age also were examined for nematode parasites. The intestinal parasite fauna of the dogs included three protozoan species (Cystoisospora canis, Cystoisospora ohioensis/burrowsi, Sarcocystis spp.), three cestode species (Dipylidium caninum, Taenia hydatigena, Echinococcus granulosus), five nematode species (Ancylostoma caninum, Uncinaria stenocephala, Toxocara canis, Toxascaris leonina, Trichuris vulpis) and one acanthocephalan (Centrorhynchus buteonis). Rates of infection were: 15.3% for C. canis, 31.5% for C. ohioensis/burrowsi, 1.8% for Sarcocystis spp., 65.8% for D. caninum, 16.2% for T. hydatigena, 2.7% for E. granulosus (genotype G1), 13.5% for A. caninum, 64.9% for U. stenocephala, 75.7% for T. canis, 0.9% for T. leonina, 21.6% for T. vulpis and 0.9% for C. buteonis. Up to six species of gastrointestinal parasites were found per dog. The 63 ≤ 6-month-old dogs harboured significantly (p<0.001) fewer gastrointestinal parasite species concurrently (mean 2.65 ± 1.25 species per animal) than the 48 older animals (mean 3.77 ± 1.45 species per animal). Dogs >6 months of age harboured significantly (p<0.05) more D. caninum, T. hydatigena, A. caninum, U. stenocephala and T. vulpis compared to younger dogs. Conversely, the younger dogs harboured significantly (p<0.001) more T. canis than the older ones. There was no difference in the male and female dogs' counts of individual intestinal helminth species apart from T. hydatigena in dogs >6 months of age: Male dogs harboured significantly (p<0.05) more tapeworms than female dogs. Based on faecal examination, there was no indication for lungworm infection; however, two adult heartworms (Dirofilaria immitis) were found in the right ventricle of one dog.
