[Effect of environmental conditions on parasitic infection of dogs].

The following intestinal parasites: Dipylidium caninum, Taenia hydatigena, Trichocephalus vulpis, Ancylostoma caninum, Uncinaria stenocephala, Toxocara canis, Toxascaris leonina, Ascaris sp. have been found on the basis of coprological investigations of 120 dogs from the Wrocłow shelter, 20 dogs from Wrocłow flats and 20 dogs from rural area of Kielce district. Total extensity of infection of rural dogs was 100% and 40-48% in town. These differences, according to the authors, are connected with different breeding conditions as well as with the specific contacts of investigated animals with others in various environments in Poland.
