Pyrophosphate-dependent 6-phosphofructo-1-kinase (PPi-PFK) from Propionibacterium freudenreichii is a non-allosteric enzyme with properties dissimilar to those of other described phosphofructokinases. The enzyme was cloned into pBluescript, sequenced, and expressed in Escherichia coli at levels 15 times higher than those observed in Propionibacterium. The gene consists of 1215 bases which code ...

Little is known about the etiology of progressive macular hypomelanosis, although it has been suggested that Propionibacterium acnes plays an important role. While microbiological culture is commonly employed to identify Propionibacterium acnes, new identification methods have been under investigation, amongst them polymerase chain reaction. To determine the cut-off point for the number of geno...

PURPOSE To report a case of Propionibacterium acnes endophthalmitis in a patient with an Ahmed glaucoma valve. CASE REPORT A nine-year-old boy with bilateral congenital glaucoma, with an Ahmed glaucoma valve implanted in the left eye, had recurrent conjunctival dehiscence and endophthalmitis. RESULTS Vitreous cultures demonstrated the presence of Propionibacterium acnes. CONCLUSIONS This ...

Propionibacterium freudenreichii subsp. freudenreichii DSM 20271(T) is the type strain of species Propionibacterium freudenreichii that has a long history of safe use in the production dairy products and B12 vitamin. P. freudenreichii is the type species of the genus Propionibacterium which contains Gram-positive, non-motile and non-sporeforming bacteria with a high G + C content. We describe t...

Moore, W. E. C. (Virginia Agricultural Experiment Station, Virginia Polytechnic Institute, Blacksburg) and Elizabeth P. Cato. Validity of Propionibacterium acnes (Gilchrist) Douglas and Gunter comb. nov. J. Bacteriol. 85:870-874. 1963.-ATCC strains of Corynebacterium acnes 11827, 6921, and 6922 were tested and consistently found to ferment lactate with the production of propionate, acetate, and...

A collection of propionibacteria was screened for bacteriocin production. A new bacteriocin named propionicin T1 was isolated from two strains of Propionibacterium thoenii. This bacteriocin shows no sequence similarity to other bacteriocins. Propionicin T1 was active against all strains of Propionibacterium acidipropionici, Propionibacterium thoenii, and Propionibacterium jensenii tested and al...

Introduction. The Propionibacterium acnes and the Staphylococcus cohnii ssp. cohnii are occasional pathogenic bacteria. The intrascrotal localization of the Propionibacterium acnes is exceptional. The Staphylococcus cohnii ssp. cohnii is not able to colonize the urogenital apparatus but it is the most frequently responsible for blood culture contamination even if it can sustain, in particular c...

Propionibacterium acnes and Staphylococcus epidermidis have been recognized as pus-forming bacteria triggering an inflammation in acne. The present study was conducted to evaluate antimicrobial activities of Thai medicinal plants against these etiologic agents of acne vulgaris. Crude extracts were tested for antimicrobial activities by disc diffusion and broth dilution methods. The results from...

Propionibacterium namnetense was recently described as a potential bone pathogen, which is closely related to Propionibacterium acnes, a skin commensal microorganism. Here, we report the draft genome sequence of the highly rifampin-resistant strain NTS 31307302(T) isolated from a patient with a tibia infection.
