Fig 6. Serotype-specific propensity for isolation as a primary or non-primary isolate.
Pneumococcal serotypes identified from nasopharyngeal swabs of Nepalese children aged 6 weeks to 24 months from the Kathmandu Valley, Nepal, were classified as to whether they occurred as a primary or non-primary isolate (*p<0·05). Specifically for each serotype: 15B, 10A, 35A, 34, 35F, 16F, 20, NT4b, 13, and NT4a p<0.0001; 6A p = 0.0005; 6B, 19A and 6C p = 0.0012; 23A and 33B p = 0.0016; NT2 p = 0.0257; 23F p = 0.0035; 4 p = 0.0101. The serotypes, 9V, 14, 19F, 3, 11D, 17F, 35B, 35C, 39, 7C, 45, 15, 7B, 8, 9N, 18C, 15A, 23B, 29, 22A, 28F, 31, 33C, 6D, 19B, 10F, 24A, 38, 48, 9L, 11A, 11B, 12F, 17A, 18A, 24B, 32F, 33A, 33F, 36, 1, 5, 7F, NT3b, 25F, 28A, 37, 40, 19C, and NT were not labelled and/or had non-significant p-values and/or were isolated on less than five occasions. MGS = Mitis-group Streptococcus.
