Temporal progression of the distribution of Streptococcus pneumoniae serotypes causing invasive pneumococcal disease in Galicia (Spain) and its relationship with resistance to antibiotics (period 2011-2021).

Introduction: Streptococcus pneumoniae causes serious diseases in the susceptible population. The 13-valent pneumococci conjugate vaccine (PCV13) was included in the children's calendar in 2011. The objective of the study was to analyze the evolution of pneumococcal serotypes and their resistance after PCV13.

[Streptococcus pneumoniae: serotype distribution, antimicrobial susceptibility, risk factors and mortality in Galicia over a two year-period].

Introduction: To examine the epidemiology of pneumococcal infection in Galicia (Spain) after the incorporation of the pneumococcal conjugate vaccine, and to determine serotype distribution, antibiotic susceptibility, risk factors and associated mortality in cases of invasive pneumococcal disease (IPD) during 2011 and 2012.

Methods: All strains causing IPD in Galicia were studied. Serotyping was performed by agglutination and Quellung reaction.

[Influence of age on the clinical manifestations of invasive pneumococcal disease and antibiotic resistance rates].

Background And Objective: Invasive pneumococcal disease (IPD) shows different epidemiological characteristics depending on age and pneumococcus serotype. The aims of the work were to analyze the clinical manifestations and mortality associated with IPD, the serotype isolated and the antibiotic resistance rates in different age groups.

Patients And Method: Retrospectively, 141 patients with IPD diagnosed between 2002 and 2008 were studied.
