Abstract
Objective: To describe the profile of Streptococcus pneumoniae, identify research gaps, and provide in‐depth insights into various aspects related to the pathogen.Methods: Google Scholar, PubMed, and ScienceDirect were searched for all studies on the pneumococcus in Ghana that reported on specimen collected, population and sample size, carriage prevalence, incidence of pneumococcal diseases, age of the study population, types of test performed, serotypes identified, antimicrobial susceptibilities, or molecular analysis on the pneumococci for data extraction.Results: Overall, a total of 7954 results were obtained from the three‐database search, and of this, 24 articles were selected after screening. A total of 924 isolates were accounted for by serotyping/serogrouping. The prevalence of pneumococcal carriage in Ghana ranges from 11.0% to 51.4% in the population depending on the age (≤ 24–80 years), sickle cell disease (SCD), human immunodeficiency virus (HIV) status, or health of the study population, and penicillin (Pen)‐nonsusceptible isolates ranged from 17% to 63%. The prevalence of pneumococci found as the etiologic agent of diseases among Ghanaians ranges from 3.4% for otitis media to 77.7% for meningitis. Overall, the 13‐valent pneumococcal conjugate vaccine (PCV) (PCV‐13) carriage serotypes accounted for 28.4% of the reported pneumococcal isolates. PCV‐13 invasive serotypes accounted for 22.4% of the reported isolates. The non‐PCV‐13 carriage serotypes accounted for most (43.9%) of the reported isolates. In the pre‐PCV‐13 era, the nontypeable (NT) (5.5%) and other nonvaccine types (NVTs) (6.4%) were reported as being predominant. The non‐PCV‐13 serotypes accounted for 4.4% of the reported isolates in invasive pneumococcal disease (IPD) cases. Multidrug resistance (MDR) ranged from 7.8% to 100%.Conclusion: Predicting the invasiveness of pneumococci using molecular typing is the way to go in the future as this will provide answers to the extent to which capsular switching is contributing to the pneumococcal disease burden in Ghana almost a decade after introducing PCV‐13. Continuous monitoring of antibiotic resistance patterns at both phenotypic and genotypic levels, along with serotyping and molecular typing, should be a standard practice in the surveillance of pneumococcal disease burden in Ghana.
