Prevalence of blood types A, B and AB in mixed breed domestic cats of Porto Alegre, Rio Grande do Sul, Brazil
AbstractThe present study was carried out to determine the prevalence of the blood types in mixed breed domestic cats of Porto Alegre, Rio Grande do Sul, Brasil. A hundred of clinically healthy mixed breed and non-related cats were selected. Blood samples were collected from the jugular vein and the blood typing was performed by RapidVet H Feline test (DMS Laboratories, Flemington, USA) and by hemagglutination tube test. Reverse blood typing was done to confirm the blood types and the presence of alloantibodies. In the present study the prevalence of blood type A and B in cats were 97% and 3%, respectively. No AB blood type cats were found. These results indicate that there is a high prevalence of blood type A mixed breed domestic cats in the south of Brazil, although the prevalence o B cats found is higher than reported in some countries. The knowledge of feline blood types prevalence in cat population can help to determine the risks of transfusion reactions and neonatal isoerythrolysis, and these can be avoid by blood typing and cross-matching test.
