Within-host genetic diversity of pneumococcal serotype 3 during one-year prolonged carriage in a healthy adult.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Streptococcus pneumoniae adapts within hosts through genetic variation and genome plasticity, facilitating persistence under antibiotic and immune pressures. Here, we investigated a prolonged pneumococcal carriage episode (>337 days) in a healthy, HIV-uninfected adult in Malawi. Whole-genome sequencing of single-colony isolates and plate sweep samples confirmed persistent colonisation by a multidrug-resistant serotype 3 strain with a distinct sequence type (GPSC10-ST18362), which maintained stable predominance despite transient acquisition of other serotypes. The sequentially sampled isolates showed 2 to 11 single-nucleotide polymorphism differences, no evidence of recombination, and modest gene loss involving mobile genetic elements. The total genome size decreased from 2.06 Mb to 2.03 Mb across isolates. Intrahost single-nucleotide variants were identified in genes related to metabolism, stress response, and DNA repair, but showed no consistent signatures of positive selection. Capsular locus analysis revealed deletions consistent with GPSC10-related vaccine-escape profiles. These findings highlight the capacity of GPSC10-ST18362 to persist asymptomatically for months with limited within-host genomic diversity.
