THE RELATIVE IMPORTANCE OF THE CAPSULE AND THE M-ANTIGEN IN DETERMINING COLONY FORM OF GROUP A STREPTOCOCCI

Evidence is presented showing that the surface configuration of Group A streptococcal colonies depends largely on whether or not the cocci form a capsule. Strains which form capsules during growth on agar produce mucoid or matt colonies. Strains that do not form capsules during growth on agar produc...

description Evidence is presented showing that the surface configuration of Group A streptococcal colonies depends largely on whether or not the cocci form a capsule. Strains which form capsules during growth on agar produce mucoid or matt colonies. Strains that do not form capsules during growth on agar produce glossy colonies. Whether or not M antigen is formed by the growing cocci appears to have no direct effect on surface configuration of the colony, although there is an indirect and partial association between M production and the mucoid-matt variant state and between M deficiency and the glossy variant state.
