The prevalence of penicillin nonsusceptible strains in the NP carriage and invasive disease group was 16.4% and 17%, respectively, in the first period and 42% and 45% in the second period. The serotypes 23F, 6A, 14 and 19F were the most common in the NP study and 14, 1, 5 and 6B were the most common in invasive infections. From the *Santa Casa S.
