Figure 1. Prevalence of pcpA, psrP and pilus-1.

Figure 1

(A) Prevalence for pcpA, psrP and pilus-1 alone and for their combinations (isolates with al least one of the three combinations) in 458 pneumococcal isolates of patients with invasive pneumococcal disease (IPD) and in 89 pneumococcal isolates of healthy nasopharyngeal carriers. (B) Prevalence of strains that carry all three proteins, and two of possible protein combinations including pcpA and psrP, psrP and pilus-1, pcpA and pilus-1 among pneumococcal isolates of patients with IPD and healthy nasopharyngeal carriers.
