A 86 year old woman, in good health but "Escherichia coli" urinary infection, was found to have an abnormality in blood group determination. 3 years ago, blood group of this patient was group A and now, precise determination shows the existence of an acquired B antigen. Disappearance of this acquired B Ag was obtained in 3 months after the urinary infection's treatment. The most cases of acquired B Ag result from neoplasic diseases or infection with enterobacteriacea. Physiopathology of acquired B Ag is secondary to the action of a deacetylase enzyme produced by enterobacteriacea, on group A1 erythrocytes.
一名86岁健康女性，但患有“大肠杆菌”尿路感染，在血型测定中发现异常。3年前，该患者血型为A型，而现在精确测定显示存在获得性B抗原。尿路感染治疗3个月后，这种获得性B抗原消失。大多数获得性B抗原病例源于肿瘤疾病或肠杆菌科感染。获得性B抗原的病理生理学继发于肠杆菌科产生的脱乙酰酶对A1型红细胞的作用。
