Transfer of resistance plasmids occurred by conjugation in Streptococcus pneumoniae (pneumococcus) similiarly to the process in other streptococcal groups. The 20-megadalton plasmid pIP501 mediated its own DNase-resistant transfer by filter mating and mobilized the 3.6-megadalton non-self-transmissible pMV158. Pneumococcal strains acted as donors or as recipients for intraspecies transfers and for interspecific transfers with Streptococcus faecalis. Transfer-deficient mutants of pIP501 have been found.
