Serogrouping of Bacteroides fragilis subsp. fragilis by the agglutination test. 1976

D W Lambe, and D A Moroz

The agglutination technique was used to establish a serological classification scheme for 98 strains of Bacteroides fragilis subsp. fragilis isolated from clinical specimens and normal human feces. Absorbed antisera were prepared to seven strains of B. fragilis subsp. fragilis. These seven absorbed antisera were species as well as subspecies specific and provided the basis of the serological classification scheme. This scheme was composed of 21 serogroups; seven of these serogroups contained only one group component. There was a total of 45 serological patterns. This serological scheme may be used for the serological classification of strains of B. fragilis subsp. fragilis and to study the epidemiology of this organism.
