Ocorrência de DEA 1.1 nos cães doadores de sangue atendidos em Hospital Veterinário Universitário em Cuiabá, Mato Grosso

Abstract

The aim of this work was to evaluate the occurrence of DEA (Dog Erythrocyte Antigen) 1.1 in donor dogs attended at the Federal University of Mato Grosso, Campus Cuiabá and to correlate it with the available literature. Sixty blood samples (approximately 1.5 ml) were collected in blood count tubes containing Ethylenediamine Tetraacetic for a complete blood count. The samples were typed with the RapidVet method, based on the agglutination reaction that occurs when an erythrocyte which contains a DEA 1 antigen on its surface membrane interacts with a murine monoclonal antibody which is lyophilized on the test card. 81.6% (49) of the tested samples (60) were DEA1.1, whereas only 18.3% (11) were DEA 1.1 negative. Purebred dogs represented 42.8%, and half breed dogs, 38.3% of DEA 1.1 positive samples. In regard to sex, 48.3% were male and 33.3%, female. This work demonstrated the high prevalence of DEA 1.1 in blood donnors canine populations, which confirms the importance of blood typing before blood transfusion in previously sensitized dogs.
