Stjernholm, Rune L. (Western Reserve University, Cleveland, Ohio) and Frank Flanders. Metabolism of d-ribose-1-C(14) and C(14)-labeled d-gluconate in an enzyme system of the genus Propionibacterium. J. Bacteriol. 84:563-568. 1962.-Ribose-1-C(14) and potassium gluconate labeled in different positions were incubated with cell-free extracts of Propionibacterium shermanii. The resulting propionate,...

OBJECTIVES To evaluate the effects of the anti-inflammatory hydroxystilbene, resveratrol, on Propionibacterium acnes growth. METHODS Three different strains of P. acnes were tested against resveratrol at concentrations between 0 and 200 mg/L. Piceatannol was included as a second hydroxystilbene to compare with resveratrol, and erythromycin and benzoyl peroxide were used as positive controls. ...

The fluorescence spectra of colonies of Propionibacterium acnes were studied under various experimental conditions. The spectra contained peaks at 580 nm and 620 nm. These bands were due to two different components; the 580 nm component was likely to be a metalloporphyrin, and there are indications that the 620 nm component could be a coproporphyrin. The 580 nm fluorescence was destroyed by the...

A case of endocarditis caused by Propionibacterium acnes associated with an aortic root abscess is presented. This supports the current opinion that aortic root abscesses are not necessarily associated with microorganisms of high virulence.

The major volatile acid produced by Haemophilus vaginalis was acetic acid. The absence of propionate, butyrate, and cellular branched-chain fatty acids indicates that H. vaginalis is not related to Propionibacterium or Butyribacterium.

The skin surface varies topographically owing to regional differences in skin anatomy and, according to culture-based studies, these regions are known to support distinct sets of microorganisms [1]. Regions with higher temperature and humidity encourage growth of Gram-negative bacilli, coryneforms and Staphylococcus aureus, whereas areas with high density of sebaceous glands encourage growth of...

The increase in our knowledge of the immune mechanisms leading to the formation of the sarcoid granuloma unfortunately has not resolved the key question dealing with the etiologic agent(s) causing the disease. In this article, many genomes of Propionibacterium acnes or Propionibacterium granulosum were detected in specimens from 15 lymph node biopsies from 15 patients with sarcoidosis by using ...

Two propionibacteria identified as Propionibacterium acnes and Propionibacterium granulosum were grown anaerobically in the presence of growth subinhibitory concentrations (0.25 and 0.5 minimal inhibitory concentrations) of clindamycin, erythromycin, lincomycin, and tetracycline. Viable counts and assays of extracellular lipase were performed on samples taken at 24-h intervals over a 96-h perio...

Consumption of human breast milk (HBM) attenuates the incidence of necrotizing enterocolitis (NEC), which remains a leading and intractable cause of mortality in preterm infants. Here, we report that this diminution correlates with alterations in the gut microbiota, particularly enrichment of Propionibacterium species. Transfaunation of microbiota from HBM-fed preterm infants or a newly identif...
