Dog Blood Type DEA 1 in Two Municipalities of Luanda Province of Angola (Sub-Saharan Africa).

In dogs, the risk of an acute hemolytic transfusion reaction at the first transfusion is negligible; however, mismatched transfusions may produce alloimmunization. To avoid fatal acute hemolytic reactions in subsequent blood transfusions, it is important to recognize blood groups and to blood type both the donor and the recipient. Prevalence of dog blood groups varies geographically and between breeds. Our aim was to determine DEA 1 prevalence in a canine population in Luanda (Angola) and to assess alloimmunization risk after a mismatched blood transfusion. Blood samples were typed using an immunochromatographic strip technique. Of the 112 dogs tested (59 males; 53 females), 52.68% were DEA 1 positive and 47.32% DEA 1 negative. Females tended to be DEA 1 positive, and males DEA 1 negative (
