The methods described in this document are intended for testing commonly isolated anaerobic bacteria. The agar dilution method may be used to test a variety of anaerobic organisms. Currently, the broth microdilution method is suggested only for testing organisms from the Bacteroides fragilis group. If and when other applications are approved, they will be published in subsequent versions of M11 and in annual updates of CLSI document M100.
