Unique genetic diversity of Propionibacterium acnes isolated from human facial skins in Thailand revealed by the multi-locus sequence typing scheme.
Article in BMC microbiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
BACKGROUND/OBJECTIVE(S)/
introductionAcne vulgaris, a prevalent dermatological concern, has shown a consistent increase in reported cases from 2016 to 2019, according to data from the Institute of Dermatology, Thailand. This condition not only causes physical and psychological discomfort but also poses treatment challenges, including the potential development of antibiotic resistance. However, the precise role and distribution of Propionibacterium acnes, an acne-associated bacterium, remain unclear among the Thai population. This study aimed to investigate the prevalence of different P. acnes groups in facial samples from Thai individuals. MATERIALS AND
methodsFacial swabbing was performed to collect bacterial samples from facial skin of Thai individuals. The 16 S rRNA gene was analyzed for species identification. Multi-locus sequence typing (MLST8) was employed to classify sequence types (STs), clonal complexes (CCs), and phylotypes.
resultsAmong the 65 P. acnes isolates, five closely matched sequence types (ST22, ST36, ST53, ST101, and ST115), five corresponding clonal complexes (CC1, CC2, CC3, CC5, and singleton type IA2), and three phylogroups (IA1, IA2, and IB) were identified. Notably, substantial differences were observed in the Thai samples analyzed in this study compared to findings from previous research. Specifically, CC2 (type IA2) emerged as the predominant type, in contrast to the predominance of CC1 (type IA1) reported in other studies. Furthermore, phylotype II, which has been documented elsewhere, was not detected in the present study. These variations in P. acnes prevalence highlight considerable genetic diversity across studies, potentially influenced by factors such as anatomical sampling sites and geographical regions.
conclusionThe isolates identified in this study will serve as valuable resources for future research on P. acnes diversity and for the development of population-specific acne treatments, particularly tailored to Thai individuals.
