Using this model three competence-deficient pneumococci, which was identified by PCR and transformation experiment, were constructed. It is found different strain has different bacterial optimal density for being induced into competence. The optimal density for strains 1, 2 and 22 was 0.1, 0.08and 0.07 respectively. The optimal condition for transformation is c plus y culture at pH8.0. In c plus y culture at pH6.8, which restrained pneumococci forming transformation naturally, pneumococci could be induced to form transformation by CSP.It is concluded that we could induce different S.pneumoniae by CSP into competence in their optimal density in laboratory. 2. It was discussed the relationship between pneumococcal transformation formation and its opportunistic pathogenesis. Comparing their virulence with that of parental strains by challenging mice intraperitoneally and adhering to ECV-304 cell respectively.
