Title : Frequency of feline blood types in non-pedigree cats in France

Summary : Many studies have shown that the prevalence of feline blood types varies geographically as well as by breed. The most important blood group system in cats is the AB system (Types A, B and AB). Notably, all Type B cats possess strong, naturally occurring anti-A alloantibodies, which may be associated with life-threatening immune-mediated hemolytic transfusion reactions. The aim of this study was to determine the prevalence of feline blood groups in non-pedigree cats in France and calculate the relative risk of a life-threatening immune-mediated hemolytic transfusion reaction caused by unmatched transfusions in this population. Blood specimens collected from sick and healthy cats were obtained from a referral hospital (Auvergne Rhne Alpes region) and a veterinary clinical pathology laboratory which receives specimens from the entire French territory, with a majority from region of Auvergne Rhne Alpes. Blood typing was performed using immunochromatographic technology. Blood specimens from 231 nonpedigree cats were blood typed for the AB system. The prevalence of blood types was as follows: 89.6% were Type A, 10% were Type B, and 0.4% were Type AB. In this study, the prevalence of Type B exceeds that in numerous other countries, including the United States and Canada. The probability of a high-risk A-B mismatched transfusion was estimated to be 9%. The high prevalence of Type B non-pedigree cats in France highlights the importance of performing blood typing prior to any blood transfusion to avoid a potentially life-threatening hemolytic transfusion reaction.
