All serum samples from endemic areas were positive for Leishmania sp., by ELISA and IFAT, 51% positive for Babesia canis and 43% for Ehrlichia canis by IFAT. None of the serum samples from non-endemic areas were positive for Leishmania sp., by IFAT, but 67% were positive for B. canis and 78% for E. canis using the same test. When tested by ELISA for Leishmania sp., four samples from non-endemic area were positive. These dogs were then located and no clinical signs, parasites or antibody was detected in new tests for a six month period. Only one of these 4 samples was positive for B. canis by IFAT and ELISA and three for E. canis by IFAT. The results of the work suggest a co-infection in the endemic area and no serological cross-reaction among these parasites by IFAT and ELISA.7-11engbacterium antibodyprotozoon antibodyanimalBabesiabloodcross reactiondogEhrlichia canisenzyme linked immunosorbent assayfluorescent antibody techniqueimmunologyLeishmaniaAnimalsAntibodies, BacterialAntibodies, ProtozoanCross ReactionsDogsEnzyme-Linked Immunosorbent AssayFluorescent Antibody Technique, IndirectArtigo10.1590/S1984-29612008000100002S1984-29612008000100002WOS:000257172000002Acesso aberto2-s2.0-540491516152-s2.0-54049151615.pdf
