M. Tsubokura et al., CHARACTERIZATION OF YERSINIA-PSEUDOTUBERCULOSIS SEROGROUPS O9, O-10 AND O-11 - SUBDIVISION OF O1 SEROGROUP INTO O1A, O1B, AND O1C SUBGROUPS, Zentralblatt fur Bakteriologie, 278(4), 1993, pp. 500-509
In this study, three new antigens (O9, O10 and O11) of Yersinia pseudo
tuberculosis are described. The O1 antigen is further subdivided into
O1a, O1b and O1c. The methods used to prepare specific antisera for O-
antigen identification are also described. Furthermore, the H antigens
of these new serogroups are determined and their biochemical characte
ristics analysed. The antigenic formulae of the known serogroups withi
n the basic antigenic scheme introduced by the authors' laboratories a
re presented.
