Abstract

Summary

A series of 2027 genital tract specimens was cultured for species on non-selective chocolate agar and on a selective medium (Choc-VBCA). The latter gave a significantly higher isolation rate. was isolated from 27 specimens and from 81 specimens by use of the selective medium. The biotype distribution of both species was compared with that of an equal number of isolates from respiratory-tract secretions. biotypes II and IV were found to predominate in genital strains and biotypes II and III in respiratory strains. With , biotype II was most frequent in both sites. Two new biotypes of (VI and VII) are described. The significance of the use of selective media and of biotype distribution are discussed.
