Avaliacao das infeccoes por Babesia e Ehrlichia em caes e das infeccoes humanas por carrapatos oriundos desses caes no municipio de Campinas, Estado de Sao Paulo Revista Brasileira de Medicina Veterinaria, 33(4):238-245, 2011. Laboratorio de Ixodides, IOC/Fiocruz, Av. Brasil, 4365, Manguinhos, Rio de Janeiro, RJ 21040-360, Brasil. E-mail: nmsf@ioc.fiocruz.br Canine babesiosis is a parasitic illness whose agents are transmitted by ticks. The infection for the genus Babesia sort compromises multiple agencies, and the severity of the manifestations is dependent of the intensity of hemolisis promoted by the blood parasites, and of the susceptibility of the host. Canine erlichiosis is illness caused for Gram-negative bacteria that occur, mainly, the dogs and the man. Ehrlichia canis is the agent most commons, and cause the form most severe of the illness, called Canine Tropical Pancitopenia. The agents of these blood parasites are transmitted by Riphicephalus sanguineus, which in Brazil already was cited in human beings. The present study if it considered to draw the clinical profile of the dogs domiciliated in the Municipality of Campinas, SP, in simple and multiple infections for the bioagentes Babesia spp. e Ehrlichia spp., and esteem the infection risk human being for these agents transmitted for deriving ticks of the dogs. Of 1.593 dogs taken care of in clinical veterinarians in the period of January the December of 2008, the sex, diverse races had been evaluated 744 dogs of both and ages, considered suspected for blood parasites. In 2009 319 removed ticks of 106 people had been examined who worked in clinical veterinarians, or that human beings in the periphery of Campinas took care of the dogs in housings, identifying them and searching if or they were not infected by the hemoparasitos. The half of the animals taken care of in the two clinics presented clinical suspicion of infection for Babesia spp. e Ehrlichia spp., being the majority coming from the periphery of the city of Campinas. The prevalence coefficient was of 9,95%, predominating in the clinical picture the signals of spleen hypertrophy and gradual loss weight, having the dogs of the infected race poodle, as well as the male animals, with definite race and ages above of one year. The infections of the dogs for Babesia spp. it was dominant, as well as in the removed ticks of human beings (CP = 9.09% for Babesia, and CP = 1.25% for Ehrlichia). The relative risk was of 0.49 times more possibility of infection human being for ticks between the people who work or take care of the dogs.
