Prevalence of Intestinal Helminthes of Dogs That Have Been Disposed Off At Non-Descript Abattoirs in Zaria, Nigeria

Abstract

Parasitological investigation of dogs disposed off in non-descript abattoirs was carried out in two communities (Basawa and Angwagodo) in Zaria. Intestines from seventy (70) adult dogs were collected, and standard procedures were followed to determine their parasite loads. A total of sixty-three dogs (90.00%) were positive for different species of helminthes. The helminthes recovered were Dipylidium caninum, Taenia spp, Ancylostoma caninum and Toxocara canis. D. caninum was present in thirty five dogs (50.00%), Taenia spp in twenty dogs (28.57%). Ancylostoma caninum in twenty five dogs (35.71%) and Toxocara canis in four dogs (5.71%). There were no statistically significant associations between the location of study and frequency of recovery of each helminthes (P>0.05). Toxocara canis was only detected at Angwagodo. The mean worm load by location was higher at Angwagodo (24.59+55.03) than Basawa (8.66+9.44). The sex of the dog had no significant effect on the recovery of each helminthes (P>0.05). However, female dogs had a higher worm load (22.14+57.41) than the male dogs (12.12+18.44). The result of this study suggests that about 90% of the dog population in Zaria may be contributing to the contamination of the environment with eggs of zoonotic helminthes.
