E-mail: [e-mail] The investigations of leptospirosis and brucellosis canine act as sanitary control in public health and zoonoses because they were established by close contact between dog and human. The aim was to determine the main hematological reagents in asymptomatic dogs against Leptospira spp. Brucella abortus and Brucella canis naturally infected, living in urban areas in the city of Uberlandia, Minas Gerais. We examined 140 blood samples from clinically healthy dogs, males and females and different ages. Leptospirosis was diagnosed by microscopic agglutination test (MAT), with a collection of twelve serovars, whereas, brucellosis was identified through the tests of Agar Gel Immunodiffusion (AGID) for B. canis and buffered acidified antigen (TAA) confirmed 2-Mercaptoethanol (2-ME) for B. abortus. The results were analyzed using descriptive statistics with the calculation of simple percentages, mean and standard deviation. He applied and short sample t test for two independent samples to assess whether there were significant differences (p<0.05) between hematological parameters obtained. Dogs evaluated, 15% (21/140) and 2.85% (4/140) were reactive to Leptospira spp. and B. abortus, respectively. There was no sample reagent against B. canis. It was concluded that although no specific thrombocytopenia may be a significant finding in dogs with leptospirosis and brucellosis.
