Biotyping of Nontypeable Group B Streptococci (original) (raw)

In this study the nontypeable Group B Streptococci (GBS) of bovine and human origin were classified by biochemical techniques. According to serotyping by co-agglutination test using rabbit monospecific serotype antisera, 40 (49.4%) of 81 bovine and 30 (32.3%) of 93 human GBS isolates were found as nontypeable (NT). The various biochemical properties of NT GBS isolates were statistically analyzed and isolates were classified according to cluster variables. Bovine and human NT isolates were classified in four and three different biotype patterns. It was concluded that these patterns will be a guide for the identification scheme of bovine and human GBS isolates and raised the question if there are new no-named isolates other than Streptococcus agalactiae in GBS?
