Factores asociados a endoparásitos y ectoparásitos en perros domiciliados de la zona metropolitana de Toluca, México:

Introduction: Endoparasites and ectoparasites in dogs are diseases with a global distribution, The close relationship between dogs and man, establishes a risk in the transmission of zoonotic parasites. Therefore it is necessary to know the parasites in dogs in an specific area and the factors associated with their presence. Objectives: To identify and estimate the prevalence of endoparasites and ectoparasites in domiciled dogs in the Metropolitan area of ​​Toluca, Mexico, and the prevalence of D. caninum in fleas of the genus Ctenocephalides spp.Materials and methods: samples were collected from 402 domiciled dogs in four reference hospitals in the area. For the diagnosis of endoparasites the direct smear, flotation and sedimentation techniques were performed; for ectoparasites the taxonomic identification of the collected specimens was performed. Finally, the molecular diagnosis of D. caninum in fleas was made using the polymerase chain reaction technique (PCR). Results: 37.2% dogs were positive for endoparasites, the genera or species identified were Toxocara spp., Giardia spp., Ancylostoma spp., Cystoisospora spp., D. caninum, Taenia spp. and Trichuris vulpis; prevalence of ectoparasites was 13.13%. Fleas of the species Ctenocephalides felis, Ctenocephalides canis, were identified, only one animal was parasitized with Rhipicephalus sanguineus and another with Trichodectes canis; the prevalence of D. caninum in fleas was 9.5%. Conclusion: The prevalence of endoparasites was 37.2%, while that of ectoprasites was 13.1%; for the first time in Mexico, an analysis of endoparasites and ectoparasites is carried out in the same population of dogs, as well as the molecular diagnosis of D. caninum in fleas.
