ABSTRACT Streptococcus pneumoniae (the pneumococcus) produces 1 of 91 capsular polysaccharides (CPS) that define the serotype. The cps loci of 88 pneumococcal serotypes whose CPS is synthesized by the Wzy-dependent pathway were compared with each other and with additional streptococcal polysaccharide biosynthetic loci and were clustered according to the proportion of shared homology groups (HGs), weighted for the sequence similarities between the genes encoding the shared HGs. The cps loci of the 88 pneumococcal serotypes were distributed into eight major clusters and 21 subclusters. All serotypes within the same serogroup fell into the same major cluster, but in six cases, serotypes within the same serogroup were in different subclusters and, conversely, nine subclusters included completely different serotypes. The closely related cps loci within a subcluster were compared to the known CPS structures to relate gene content to structure. The Streptococcus oralis and Streptococcus mitis polysaccharide biosynthetic loci clustered within the pneumococcal cps loci and were in a subcluster that also included the cps locus of pneumococcal serotype 21, whereas the Streptococcus agalactiae cps loci formed a single cluster that was not closely related to any of the pneumococcal cps clusters.

Over Time

The epidemiology of hospitalised pneumococcal disease in adults following the introduction of universal childhood pneumococcal immunisation in 2009 was assessed. Culture-confirmed Streptococcus pneumoniae (SP) from adults hospitalised between 2009 to 2017 were examined. The cases were categorised into invasive pneumococcal disease (IPD) and pneumonia (bacteraemic, non-bacteraemic, and that associated with other lung conditions). The isolates were serotyped and antimicrobial susceptibilities were determined by microbroth dilution. Patient characteristics, comorbidities, and outcomes were analysed. Seven hundred and seventy-four patients (mean age, 67.7 years, SD ± 15.6) were identified, and IPD was diagnosed in 110 (14.2%). The most prevalent serotype, 19F, was replaced by serotype 3 over time. Penicillin and cefotaxime non-susceptibilities were high at 54.1% and 39.5% (meningitis breakpoints), 19.9% and 25.5% (non-meningitis breakpoints), respectively. The overall 30-day mortality rate was 7.8% and 20.4% for IPD. Age ≥ 75 years (OR:4.6, CI:1.3–17.0, p < 0.02), presence of any complications (OR:4.1, CI:1.02–16.3, p < 0.05), pleural effusion (OR:6.7, CI:1.2–39.4, p < 0.03) and intensive care unit (ICU) admission (OR:9.0, CI:1.3–63.4, p < 0.03) were independent predictors of 30-day mortality. Pneumococcal disease by PCV 13 covered serotypes; in particular, 19F and 3 are still prominent in adults. Strengthening targeted adult vaccination may be necessary in order to reduce disease burden.

Pneumococcal Serotype

Abstract Background Pneumococcal serotypes differ in antimicrobial susceptibility. However, patterns and causes of this variation are not comprehensively understood. Methods We undertook a systematic review of epidemiologic studies of pneumococci isolated from carriage or invasive disease among children globally from 2000-2019. We evaluated associations of each serotype with nonsusceptibility to penicillin, macrolides, and trimethoprim/sulfamethoxazole. We evaluated differences in the prevalence of nonsusceptibility to major antibiotic classes across serotypes using random effects meta-regression models, and assessed changes in prevalence of nonsusceptibility after implementation of pneumococcal conjugate vaccines (PCVs). We also evaluated associations between biological characteristics of serotypes and their likelihood of nonsusceptibility to each drug. Results We included data from 129 studies representing 32,187 isolates across 52 countries. Within serotypes, the proportion of nonsusceptible isolates varied geographically and over time, in settings using and those not using PCVs. Factors predicting enhanced fitness of serotypes in colonization as well as enhanced pathogenicity were each associated with higher likelihood of nonsusceptibility to penicillin, macrolides, and trimethoprim/sulfamethoxazole. Increases in prevalence of nonsusceptibility following PCV implementation were evident among non-PCV serotypes including 6A, 6C, 15A, 15B/C, 19A, and 35B; however, this pattern was not universally evident among non-PCV serotypes. Post-vaccination increases in nonsusceptibility for serotypes 6A and 19A were attenuated in settings that implemented PCV13. Conclusions In pneumococci, nonsusceptibility to penicillin, macrolides, and trimethoprim/sulfamethoxazole is associated with more frequent opportunities for antibiotic exposure during both prolonged carriage episodes and when serotypes cause disease. These findings suggest multiple pathways leading to resistance selection in pneumococci.
