[Bacterial flora of acne lesions in diagnostic material of the Microbiology and Immunology Department, Pomeranian Medical Academy (PAM) in Szczecin].

: A retrospective analysis of the bacterial flora of acne lesions was carried out in 320 patients. Atypical flora was isolated very rarely. The pathogenic flora was found most frequently in the Autovaccine Laboratory when the microbiological material was taken directly onto plates and the investigation was repeated several times. Atypical flora was isolated only from three cases. Propionibacterium and Staphylococcus epidermidis were found to be sensitive to the antibiotics routinely used in the treatment of acne. The highest antibacterial effect in vitro against both these species was demonstrated using rifampicin and tetracycline.
