Rapid isolation and identification of group B streptococci from selective broth medium by slide co-agglutination test.
Direct identification of group B streptococci from a selective broth medium was performed with the Phadebact streptococcus test to determine the feasibility of this technique for early detection of streptococcal colonization. Of 124 clinical isolates, 122 (98.4%) were correctly identified in less than 24 h from the selective broth medium, whereas standard cultures from blood agar plates identified, after 48 h, only 66 (53.2%). The presence of group B streptococci in mixed cultures was always detected by the Phadebact test, and no false-positive co-agglutination tests were observed in 372 cultures from which organisms other than group B streptococci were isolated.
