Spread of multidrug resistance in non-PCV13/PCV20 serotypes of Streptococcus pneumoniae: A cross-sectional study ten years after the introduction of pneumococcal conjugate vaccine in Japan
J Microbiol Immunol Infect. 2023 Jul 20:S1684-1182(23)00123-8. doi: 10.1016/j.jmii.2023.07.004. Online ahead of print.ABSTRACTTen years after the introduction of the pneumococcal conjugate vaccine (PCV) in Japan, the prevalence rates of non-PCV13 and non-PCV20 serotypes among pediatric pneumococcal isolates were 94.0% and 73.7%, respectively. The predominant non-PCV13/PCV20 serotypes (15A, 35B, and 23A) were mostly multidrug-resistant (≥80.5%), exhibiting non-susceptibility to penicillin.PMID:37517964 | DOI:10.1016/j.jmii.2023.07.004

Pneumococcal carriage, serotype distribution, and antimicrobial susceptibility in Papua New Guinean children vaccinated with PCV10 or PCV13 in a head-to-head trial
CONCLUSION: Even after PCV10 or PCV13 vaccination, children living in a high-risk setting such as PNG continue to experience high levels of pneumococcal colonization, including carriage of highly antimicrobial-resistant PCV serotypes. The study is registered with ClinicalTrials.gov (CTN NCT01619462).PMID:37479616 | DOI:10.1016/j.vaccine.2023.07.026

Serotypes and antimicrobial resistance of < em > Streptococcus pneumoniae < /em > in children under 5 years of age pre- and post-pneumococcal conjugate vaccine introduction in Paraguay
Conclusion. A change in the circulating serotypes and antimicrobial resistance to certain antibiotics was observed. Non-vaccine serotype circulation and multidrug resistance may compromise the success of the conjugate vaccines.PMID:37289483 | DOI:10.1099/jmm.0.001700

Pneumococcal serotypes and antibiotic resistance in healthy carriage children after introduction of PCV13 in Lima, Peru
CONCLUSION: The introduction of PCV13 in the immunization program in Peru has decreased the pneumococcal nasopharyngeal carriage and the frequency of PCV13 serotypes; however, there has been an increase in non-PCV13 serotypes and antimicrobial resistance.PMID:37270366 | DOI:10.1016/j.vaccine.2023.05.042

Prevalence, capsular types, antimicrobial resistance and risk factors associated with pneumococcal carriage among children after long-term 10-valent pneumococcal conjugate vaccine use in Brazil
CONCLUSIONS: Long-term universal childhood use of PCV10 has nearly eliminated carriage with PCV10 serotypes, but the high frequency of MDR isolates, especially associated with serotype 6C/D, remains a concern. Replacing PCV10 with PCV13 should reduce the proportion of ERY-R isolates and PNSP by at least 14% and 18%, respectively.PMID:37061371 | DOI:10.1016/j.vaccine.2023.04.023

Microbiological and clinical characteristics of Streptococcus pneumoniae serotype 3 infection and risk factors for severe outcome: A multicenter observational study
CONCLUSIONS: Serotype 3 infection showed a high mortality rate, especially in patients with older ages and comorbidities. Although the incidence rates decreased during the COVID-19 pandemic, serotype 3 remained as an important cause of infection after the implementation of PCV13. Developing a more effective vaccine against serotype 3 and monitoring the antimicrobial-resistant sequence types are necessary.PMID:36774315 | DOI:10.1016/j.jmii.2023.01.013
