Marín Sánchez, Clotilde Cutaneous leishmaniasis Visceral Leishmaniasis Superoxide dismutase Viannia braziliensis Dogs Diagnosis Infantum Host Canine Leishmaniasis is widespread in various Mexican states, where different species of Leishmania have been isolated from dogs. In the present study, we describe the detection of L. braziliensis, L. infantum, and L. mexicana in serum of dogs from the states of Yucatan and Quintana Roo in the Yucatan Peninsula (Mexico). A total of 412 sera were analyzed by ELISA using the total extract of the parasite and the iron superoxide dismutase excreted by different trypanosomatids as antigens. We found the prevalence of L. braziliensis to be 7.52%, L. infantum to be 6.07%, and L. mexicana to be 20.63%, in the dog population studied. The results obtained with ELISA using iron superoxide dismutase as the antigen were confirmed by western blot analysis with its greater sensitivity, and the agreement between the two techniques was very high. 2014-05-30T08:59:54Z 2014-05-30T08:59:54Z 2012 info:eu-repo/semantics/article López-Céspedes, A.; et al.
