Propionibacterium acnes is the most commonly isolated anaerobic gram-positive non-spore forming bacilli usually isolated from blood cultures bottles that may act as a contaminant.

However, the optimum culture conditions for recovery of this organism from PJI specimens have not been determined. Cutibacterium acnes (voorheen Propionibacterium acnes) is een grampositieve staafvormige bacterie die commensaal is en die zich bij ieder mens al vanaf de geboorte op en diep in de huid bevindt. De bacterie valt onder de ' residente flora ' van de huid. species ofthe genus Propionibacterium were also tested andfoundto be similar to C. acnes both in cultural characteristics and fatty acid composition.

Propionibacterium acnes (P. acnes), sedan år 2016 Cutibacterium acnes (C. acnes), [1] [2] är en vanligt förekommande anaerob bakterie i huden. P. acnes finns och lever på huden hos alla människor. Bakterien har utpekats som en av orsakerna till att symtom av akne utvecklas (finnar, pormaskar och utslag). [3]

Propionibacterium acnes was defined as the causative pathogen if it was identified in at least two culture specimens, or identified with at least two different modalities: blood culture, valve culture, valve sequencing or histopathological demonstration of microorganisms. Propionibacterium acnes is a facultative anaerobic Gram-positive rod, abundant on the human skin, and mainly associated with the sebaceous glands of the shoulder and axilla (1).

The present study examined 70 samples; 2019-12-03 · Cutibacterium (formerly known as Propionibacterium) species are nonsporulating, gram-positive anaerobic bacilli that are considered commensal bacteria on the skin. They are usually nonpathogenic The National Collection of Type Cultures comprises over 5000 bacterial cultures, Propionibacterium acnes subsp. elongatum Original Strain Reference: K124 A case patient was defined as a patient who underwent surgery on large joints (shoulder, elbow, wrist, hip, knee, or ankle) from 1996 through 2006 (index surgery) and who later developed joint infection with culture of ⩾1 deep operative specimen revealing a pure growth of Propionibacterium species. Propionibacterium acnes was identified in 12.5% of routine blood cultures, 75% of blood cultures with extended incubation, 55% of valve cultures, and 95% of valve sequencing specimens.

The Gram-positive skin bacterium Propionibacterium acnes was grown semi- anaerobically on Eagle’s medium for 16 days at pH 6.7.Porphyrins were produced and accumulated in culture-grown P. acnes.Fluorescence spectroscopy was used to identify and quantify the amount of porphyrins produced in culture during the growth of the cells.

In blood cultures, P. acnes grows better in anaerobic bottles but is also able to grow in aerobic bottles because of the anaerobic microenvironment that develops at the bottom of nonshaken bottles . The optimal temperature for growth is between 30°C and 37°C ( 47 ).

In 11 of 24 patients (46%), no causative pathogen would have been identified without valve sequencing. In addition, P. acnes may be overlooked when cultures are not rechecked or if cultures are discarded after three or five days of incubation. In a study done by Frangiamore et al. in 2015, the time to positive culture appeared to be shorter among patients with true infection with a median time of five days versus nine days among patients with probable contamination [ 12 ]. P. acnes colonizes primarily sebaceous glands and hair follicles of human skin, but it may also be found in the mouth, nares, geni-tourinary tract, and large intestine. In 2009, Patel et al.
