Studies on the Serologic Classification of B. Botulinus

II. Agglutination

From the George Williams Hooper Foundation for Medical Research, University of California Medical School, San Francisco, California

Abstract

The results of an investigation dealing with the serological relationship of 111 strains of B. botulinus (including 7 duplicate strains) isolated from a diversity of sources and from many localities have been intimated in a previous communication (1). It was stated that by means of agglutination and absorption tests Type A strains can be subdivided into at least 3 and possibly 4 groups, while the B types can be classed into at least 2 groups.

Since the publication of the preliminary notes Starin and Dack (2) have reported their studies on the serological grouping of this organism. They have shown that there are at least 3 distinct subgroups of Cl. botulinum Type B and 4 subgroups of Type A. In the case of the latter, intermediate strains, partaking of the nature of more than 1 of the 4 distinct subgroups have been noted.
