Abstract

SUMMARY

A co-operative study of 28 cultures of by three laboratories, each using different methods, is described. Two agglutination types, four sensitin types, five immunodiffusion types, three lipids types and three biotypes were recognised amongst the strains. In most cases there was good agreement between different means of typing, and the strains could be divided into three groups. Twelve strains, including the type strains of and , formed a completely homogeneous group as judged by all methods used. A second and slightly less homogeneous group of seven strains included the type cultures of and , and a third group, the least homogeneous, contained nine strains of unnamed organisms. It is suggested that the first two groups might be considered subspecies, and respectively.
