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%.
