[Association of acquired polyagglutinabilities of types T and B. An observation].

Although T and acquired B polyagglutinabilities are not exceptional, simultaneous occurence of the two types is a rarer phenomenon. Ten days after an open heart surgery operation, the patient, age 55, had an infectious syndrom : two strains, Clostridium perfringens and Peptococcus variabilis were isolated. Simultaneously, her red cells were found to be polyagglutinable. The association of T and acquired B polyagglutinabilities could be demonstrated by serological studies of the patient's red cells, and by in vitro transformation of normal red cells using culture supernatants obtained from the two isolated strains.
