Three hundred and twenty-two strains of Bacteroides fragilis isolated from infected patients at three different hospitals were tested against 20 type specific B. fragilis antisera using the tube agglutination technique. Of these strains 41.3% were assigned to a single O-serotype, a further 20.5% were agglutinated by several antisera and could not be classified and the remainder showed no reactions. Three different serotypes were prevalent in the three hospitals and minor geographical variation was observed. No correlation was found between serotypes and the origin of infection, but those from the blood were the most readily typable strains. No correlation was found between serotypes and biotypes of B. fragilis.
采用试管凝集技术，对从三家不同医院的感染患者中分离出的322株脆弱拟杆菌，针对20种脆弱拟杆菌型特异性抗血清进行了检测。这些菌株中，41.3%被归为单一的O血清型，另有20.5%能被几种抗血清凝集，无法分类，其余菌株无反应。三家医院中流行三种不同的血清型，观察到有微小的地域差异。未发现血清型与感染源之间存在相关性，但血液来源的菌株是最容易分型的。未发现脆弱拟杆菌的血清型与生物型之间存在相关性。
