Resumen:
Aim: The aim of the study was to identify the presence of eggs of
Toxocara spp. in dog hair and to identify any risk factors associated
with this.
Materials and Methods: A total of 96 dogs were sampled collecting hair
from the head, perianal and hindquarters. Epidemiologic data from each
animal were recorded to identify risk factors. The samples of hair were
washed with solutions of distilled water, phosphate-buffered saline and
Tween 20 detergent. Microscopic analysis was subsequently performed for
the identification of eggs.
Results: Out of the total dogs, 41.7% were positive for the presence of
parasite egg in their hair. Toxocara eggs were found in hair from the
head (14.5%), tail (20.8%), and limbs (10.4%). Dogs, younger than 12
months old, showed higher values (4.7%) of egg presence in the perianal
area (p< 0.05). The principal risk factors for the presence of eggs in
hair were not deworming (odds ratio [OR]= 3.60, p< 0.004) and not
brushing (OR= 2.26, p< 0.12).
Conclusion: These results show that in the state of Mexico there is a
high percentage of dogs contaminated with Toxocara spp. eggs in their
hair. This should be seriously considered due to the potential problems
of toxocariasis and the risk to public health.
