Abstract

RODRIGUEZ-PRADO, Ulises et al. Coprological and ultrasonographic study in dogs and sheep of a suburban community in the Estado de México in search of Echinococcus spp. Vet. Méx [online]. 2014, vol.45, n.spe, pp.53-58. ISSN 0301-5092.

The study described here was performed in a suburban community of the Estado de México to Echinococcus spp, since a human case of cystic echinococcosis (CE) was identified previously. Overall, 91% (406/446) of the houses were visited and oral informed consent was obtained from dog owners; a questionnaire related to their dogs was applied and a coprological sample was obtained. It was found that 14% of dog owners fed them with raw livestock viscera. Coprological studies showed that eggs of Ancylostoma and Toxocara were the most abundant, thus deworming was recommended to all owners. Dogs with Taenia spp eggs were treated and Taenia pisiformis adults were released, not from Echinococcus spp. Most sheep in the community were studied by ultrasound and viscera of those slaughtered, were visually inspected; confirming the absence of CE. Interestingly, although no evidences of Echinococcus spp were found in animals, an autochthonous human case of CE was detected in 2006; this, added to proper practices for maintaining the life cycle of this parasite, suggests that echinococcosis in Mexico has a random behavioral pattern.
