Frequencies of blood types A, B, and AB in domestic cats vary geographically and among breeds and have not been reported in China.
The purpose of this study was to survey the frequency of blood types in domestic cats in the Beijing area.
A total of 262 cats from the city of Beijing were blood-typed using a standard tube agglutination assay. All cats were nonpedigree domestic shorthaired and longhaired cats; purebred cats were excluded. Serum obtained from type-B cats and a lectin (Triticum vulgaris) solution served as anti-A and anti-B reagents, respectively. The presence of alloantibodies was also determined in some cats.
The frequency of blood types was 88.2% type A, 11.4% type B, and 0.4% type AB. The tube assay resulted in 3+ to 4+ agglutination reactions with either the anti-A or anti-B reagents. The 1 type AB sample showed 3+ agglutination with both anti-A and anti-B reagents; the plasma of that sample did not react with either type-A or type-B RBCs. Tested type-B cats had strong anti-A antibodies.
The frequency of blood type B in the Beijing area was relatively high and similar to that reported for other Asian countries and Australia. Blood-typing is recommended to match donors and recipients before transfusion therapy and planned matings to avoid hemolytic transfusion and neonatal isoerythrolysis reactions, respectively, due to blood-type incompatibility.
家猫中A型、B型和AB型血型的频率在地理上和品种间存在差异，在中国尚未见报道。
本研究旨在调查北京地区家猫的血型频率。
采用标准试管凝集试验对来自北京市的262只猫进行血型鉴定。所有猫均为非纯种家养短毛猫和长毛猫，排除纯种猫。从B型猫获得的血清和凝集素（普通小麦）溶液分别用作抗A和抗B试剂。还在一些猫中检测了同种抗体的存在。
血型频率为A型88.2%，B型11.4%，AB型0.4%。试管试验与抗A或抗B试剂产生3+至4+的凝集反应。1份AB型样本与抗A和抗B试剂均显示3+凝集；该样本的血浆与A型或B型红细胞均无反应。检测的B型猫具有强抗A抗体。
北京地区B型血的频率相对较高，与其他亚洲国家和澳大利亚报道的频率相似。建议在输血治疗和计划交配前进行血型鉴定，以分别避免因血型不相容导致的溶血性输血反应和新生儿溶血病反应。
