Abstract

The aim of this study was to identify hemoparasites and ticks of dogs treated at the Zoonoses Control Center in Campo Grande, Mato Grosso do Sul State, Brazil. Blood and venous blood smears were obtained from 167 dogs from various regions of the city. From the total of animals examined, 62.28% presented positive results for hemoparasites, and Babesia canis was found in 10.78% of samples, Ehrlichia canis in 60.48% and Hepatozoon canis in 2.40%. Among the animals evaluated, 23.95% were infested only by ticks of the species Rhipicephalus sanguineus, where there was no correlation between the presence of hemoparasites and parasitism by ticks. The results indicated that the dogs of the Zoonoses Control Center were affected by B. canis, E. canis and H. canis, Where coinfections were found between these hemoparasites, which may hinder clinical and laboratory diagnosis and also aggravate the clinical manifestations of these canine hemoparasites. Borreliae canine borreliosis has Borrelia burgdorferi lato sensu, which is transmitted by ixodidae ticks and can affect humans and animals. A total of 180 blood samples were collected from dogs from the Zoonoses Control Center of Campo Grande, State of Mato Grosso do Sul. The sera analyzed by indirect enzyme immunoadsorption (ELISA) revealed 73.3% (132) of seropositive animals, With titers ranging from 1: 400 (46.1%) to 1: 3200 (0.5%). All dogs were examined for the presence of ticks and only Rhipicephalus sanguineus was found in 15.6% (28) of the evaluated dogs. The large number of seropositive dogs detected shows the hypothesis of the occurrence of Borrelia sp. As a possible agent of Lyme borreliosis simile and in this way its relevance as emergent zoonosis. 
The objective of the present study was to identify hemoparasites and ticks of dogs at the Center for Zoonoses Control of Campo Grande in Mato Grosso do Sul State. Smears of peripheral and venous blood of one hundred and sixty seven dogs originating from many regions of the municipality of Campo Grande were realized. Of the total examined, 62.28% presented a positive result for hemoparasites, Babesia canis was found in 10.78% of samples, Ehrlichia canis in 60.48%, the Hepatozoon canis in 2.40%. Among the animals evaluated, 23.95% were infested only by ticks of species Rhipicephalus sanguineus, Where there was no correlation between the presence of hemoparasites and tick parasitism. The results indicated that the dogs of the CCZ were attacked by B. canis, E. canis and H. canis, where coinfections among these hemoparasites were found, that may hinder clinical and laboratory diagnosis and also worsen the clinical manifestations of these canine hemoparasitoses. Canine borreliosis has the etiologic agent Borrelia burgdorferi lato sensu, which is transmitted by ixodídeos ticks and can attack human and animals. Was collected 180 blood samples of dogs originating from the Control Center of Zoonosis in Mato Grosso do Sul State. The serums analyzed by the indirect enzyme-linked immunosorbent assay (ELISA) revealed 73.3% (132) of seropositive animals, with titers ranging from 1: 400 (46.1%) to 1: 3200 (0.5%) . Rhipicephalus sanguineus was found in 15.6% (28) of the dogs. The large number of dogs detected seropositive demonstrates the hypothesis of Borrelia sp. The possible agent of Lyme borreliosis is similar and in this way the relevance of this emerging zoonosis.
