Leishmaniasis is an endemic disease present in 98 countries.In Brazil, the northeast region accounts for approximately half of cases humans, and has experienced increased number positive dogs.In this study, we investigated epidemiology canine leishmaniasis city Ilhéus, Bahia, using serological molecular techniques evaluated possible environmental risk factors associated clinical signs.Blood samples were collected from 560 dogs urban peri-urban areas northeastern Brazil.Genomic DNA was extracted selected animals ©FUNPEC-RP www.funpecrp.com.brGenetics Molecular Research 14 (4): 12062-12073 (2015) subjected to analysis Leishmania species-specific primers diagnosis Trypanosoma cruzi.A total 54.72% braziliensis, both infantum T. cruzi not identified.Hematologic variables statistically with L. braziliensis.However, animal group showed lower red blood cell platelet counts higher levels urea serum creatinine.Few presented signs compatible presence Leishmania.Age more than 2 years specific hair colors results braziliensis.The geoclimatic characteristics may improve parasite survival, reproduction, vectors.This explain rate identified as study.
