Abstract
There were 88 T-type 12 group A streptococcal strains randomly selected from routine specimens (human) in 2 epidemiologically unrelated districts. All of 26 M-type 12 strains lacked IgA and IgG Fc-receptors; all 32 M-type 22 strains had IgG Fc-receptors and 20 of them also receptors for IgA Fc. The remaining strains were not further M-typed but 18 of these 30 strains exhibited receptors for IgG and 13 for IgA.
