RESUMO

This work had for objective to investigate the infection for Ehrlichia canis and Anaplasma platys in the dogs taken care of in the Veterinarian Hospital of the Universidade Federal de Mato Grosso, through the examination of blood smears and of the PCR, analyzing the clinical and laboratories findings. During the period of May of 2004 the July of 2005, 195 dogs with suggestive clinical signs of ehrlichiosis or had contact with the infection had been examined. The canine cyclic thrombocytopenia, caused for the A. platys, provokes reduction of platelets to each 14 days, without provoking severe signs, but when associated to the infection for E. canis the clinical gravity it increases. In the thirteen dogs taken care of with positive PCR for E. canis diagnosised by the PCR it was possible to verify the diversity of signals, with statistical significant predominance of the hemorrhagic riots. Already in the 195 dogs tested for the examination of blood smears it did not have predominance of no clinical signs. The hematologic findings had also been nonspecific, occurring in such a way anemia, leukopenia and thrombocytopenia, how much normality or increase of the cells. The alterations observed in the analysis biochemist had not been exclusive of the groups with infection. In these groups increase of plasma proteins occurred, with hyperglobulinaemia, without, however to have significant difference, despite this finding being frequent in ehrlichiosis. From the analysis of the PCR it was confirmed that the infection for E. canis and A. platys occur in the dogs taken care of in the Veterinarian Hospital of the UFMT, having to be taken writ of prevention, mainly in the control of the vector, since all the ticks found in the examined dogs had been of species Rhipicephalus sanguineus.
