A simple and rapid procedure to detect autolysin‐defective mutants of Streptococcus pneumoniae has been developed. The autolysin gene ( lyt ) can be introduced into the appropriate receptor strain by genetic transformation and the transformants are readily detected on the surface of semisynthetic medium (C medium) plates by using a membrane filter. A pneumococcal autolysin mutation ( lyt ‐4) behaved as a low‐efficiency marker in genetic transformation.
