ABSTRACT

In order to evaluate the monthly frequency, and the genera of cestode and nematode intestinal populations in stray dogs, post-mortem studies were done at the antirrabies center in the city of the State of Queretaro in Mexico; 201 intestines were obtained from May to September, 2000. Age and sex of each animal were recorded. Results showed a 78.6% frequency of positive dogs, and out of this percentage, 64.6% of the infections were produced by nematodes, and 58.2% by cestodes. 77.4% of the males, and 79.6% of the females were infected. No differences regarding sex or age of the animals (P › 0.05) were detected. The frequency of infected dogs during the months of the trial showed differences (P ‹ 0.05). Nematode genera, species and frequency were: Ancylostoma caninum, 55.22%; Toxocara canis, 13.93%; Toxascaris leonina, 11.91%; and for the cestode population the genera, species and frequency were: Dipylidium caninum, 54.72%; Taenia hidatigena, 3.48%; Taenia psiformis, 1.99%; and Echinococcus granulosus, 0.49%.
