Abstract:	The aim was to analyse invasive pneumococcal disease (IPD) serotypes in children aged ⩽17 years according to clinical presentation and antimicrobial susceptibility. We conducted a prospective study (January 2012-June 2016). IPD cases were diagnosed by culture and/or real-time polymerase chain reaction (PCR). Demographic, microbiological and clinical data were analysed. Associations were assessed using the odds ratio (OR) and 95% confidence intervals (CI). Of the 253 cases, 34. 4% were aged <2 years, 38. 7% 2-4 years and 26. 9% 5-17 years. Over 64% were 13-valent pneumococcal conjugate vaccine (PCV13) serotypes. 48% of the cases were diagnosed only by real-time PCR. Serotypes 3 and 1 were associated with complicated pneumonia (P < 0. 05) and non-PCV13 serotypes with meningitis (OR 7. 32, 95% CI 2. 33-22. 99) and occult bacteraemia (OR 3. 6, 95% CI 1. 56-8. 76). Serotype 19A was more frequent in children aged <2 years and serotypes 3 and 1 in children aged 2-4 years and 5-17 years, respectively. 36. 1% of cases were not susceptible to penicillin and 16. 4% were also non-susceptible to cefotaxime. Serotypes 14, 24F and 23B were associated with non-susceptibility to penicillin (P < 0. 05) and serotypes 11, 14 and 19A to cefotaxime (P < 0. 05). Serotype 19A showed resistance to penicillin (P = 0. 002). In conclusion, PCV13 serotypes were most frequent in children aged ⩽17 years, mainly serotypes 3, 1 and 19A. Non-PCV13 serotypes were associated with meningitis and occult bacteraemia and PCV13 serotypes with pneumonia. Non-susceptibility to antibiotics of non-PCV13 serotypes should be monitored PI11/02081 and PI11/02345).
