Concomitant synthesis of CPS IX and CPS V in recombinant type V and type IX strains transformed with pAM-cps5MOI and pAM-cps9MI, respectively. A and C, serotyping of wild-type and recombinant bacteria by latex agglutination. B and D, flow cytometry analysis of the same strains using anti-CPS V and anti-CPS IX mouse polyclonal antibodies. The red peaks represent negative controls only labeled with secondary antibodies; the blue peaks represent bacteria labeled with the anti-CPS antibodies.
