Bacterial strains and relevant properties^a

Strain	Properties	Reference(s) or source
2812A	Streptococcus pyogenes, Italian clinical strain, serotype M1, carrying Φ1207.3, Em^r	10
Rx1	Streptococcus pneumoniae, rough highly transformable laboratory strain, comC1-comD1, Hex⁻	40
FP10	Rx1 derivative, competence deficient (ΔcomC1), str-41, Cm^r, Sm^r	20, 34, 41
FP11	Rx1 derivative, competence deficient (ΔcomC1), nov-1, Cm^r, Nov^r	20, 34, 41
FR1	FP10 derivative carrying Φ1207.3, Cm^r, Sm^r, Em^r	This study

Em, erythromycin; Cm, chloramphenicol; Nov, novobiocin; Sm, streptomycin; comC1-comD1 encode the competence stimulating peptide and its receptor; Hex is the DNA mismatch repair system; the str-41 allele confers streptomycin resistance; the nov-1 allele confers novobiocin resistance.
