The aims of this study were to determine the prevalence of A, B and AB blood types and alloantibodies in non-pedigree cats from two regions, one in Northern and one in Southern Italy (Lombardy and Sicily, respectively). A total of 448 samples (52.0% from Northern and 48.0% from Southern Italy) were blood typed. The prevalence of A, B and AB blood types in northern and southern cats were 91.0%, 5.2%, 3.8%, and 77.2%, 12.1% and 10.7%, respectively. The prevalence of type-A blood in southern cats was significantly lower (p = 0.0001) than in northern cats, while type-B and AB blood were significantly higher (p = 0.0085 and p = 0.0051, respectively) in Southern compared to Northern Italian cats. Alloantibodies against type-A blood were found in 94.1% of type-B cats, 11.2% of type-A cats had alloantibodies against type-B blood, while no type-AB cats had alloantibodies with no significant difference between the two Italian populations. Type-AB prevalence in non-pedigree cats in Southern Italy was the highest reported in Europe. Italian type-A cats had the lowest worldwide prevalence of alloantibodies against type-B blood. These results highlight the usefulness of regional studies to report different prevalences in feline blood types and reinforce the importance of blood typing cats before transfusions and mating.

来自意大利北部（伦巴第）和南部（西西里岛）的非家谱猫的血型和AB血型系统的同种抗体的患病率。

这项研究的目的是确定两个地区的非谱系猫中A，B和AB血型和同种抗体的患病率，一个位于意大利北部，一个位于意大利南部（分别位于伦巴第和西西里）。总共进行了448个样本的血型检查（北部为52.0％，意大利南部为48.0％）。北部和南部猫的A，B和AB血型患病率分别为91.0％，5.2％，3.8％和77.2％，12.1％和10.7％。南部猫的A型血液患病率显着低于北部猫（p = 0.0001），而B型和AB型血液的患病率显着更高（p = 0.0085和p南部的猫与北部的意大利猫相比分别为0.0051）。在94.1％的B型猫中发现了针对A型血液的同种抗体，11.2％的A型猫具有对B型血液的同种抗体，而没有AB型猫具有同种抗体，在两个意大利种群之间没有显着差异。在意大利南部，非谱系猫的AB型患病率是欧洲最高的。意大利A型猫对B型血的同种抗体的全球患病率最低。这些结果突显了区域研究报告猫血型不同流行率的有用性，并增强了输血和交配前血型猫的重要性。
