    Studysummary This observational study aims to more accurately detect and localize Propionibacterium acnes in acne lesions by combining multiple microbiological visualization techniques, but it does not present new results on their causality to acne. Our plain-language summary of this paper — not a Tressless recommendation.
    The study investigated the presence and localization of Propionibacterium acnes (P. acnes) in acne lesions using advanced visualization techniques such as fluorescent in situ hybridization (FISH), immunofluorescent microscopy (IFM), immunohistochemistry (IHC), and routine histochemistry assays. The goal was to directly detect and co-localize P. acnes with inflammatory cells in acne lesions, addressing the limitations of previous culture-based studies. The findings aimed to provide more precise evidence of P. acnes involvement in acne by identifying its specific sites of colonization within the skin micro-environments.
