^aMutant strains were tested before (Er^r) and after (Er^s) pGh plasmid excision. 

^bUnless otherwise indicated, data from triplicate samples from two independently grown broth cultures were pooled (n = 6). 

^cResistance to phagocytosis is shown as the percent survival of cells relative to cells at time zero. 

^dCapsule status is shown as the amount of hyaluronidase-released N-acetylglucosamine per 10¹⁰ bacteria. 

^eData from quadruplicate samples from two independently grown cultures were pooled (n = 8).
