Some studies mention a concentration of 10–1.3 × 10 4 cfu ml −1 in French raw milk, and an average contamination of 7 × 10 2 cfu ml −1 and 2.5 × 10 2 cfu ml −1 in raw milk used for Italian Grana cheese and in Swiss raw milk, respectively. Propionibacterium acnes is the most abundant bacterium on human skin, particularly in sebaceous areas. P. acnes is suggested to be an opportunistic pathogen involved in the development of diverse medical conditions but is also a proven contaminant of human clinical samples and surgical wounds. Its significance as a pathogen is consequently a matter of debate. In the present study, we Propionibacterium acnes recently renamed Cutibacterium acnes, is a Gram-positive, non-spore-forming human skin commensal (normal bacteria of the skin) that prefers anaerobic growth conditions 1).

Few studies have addressed the clinical significance of bacteremia caused by Propionibacterium spp. One study, of 843 instances of positive blood cultures, Keywords Antimicrobial resistance, clinical isolates, Propionibacterium acnes, pulsed-field gel Brook I.

Propionibacterium acnes is a microaerophilic, anaerobic, Gram-positive bacillus, and one end product of bacterial fermentation is propionic acid. The organism is a member of the normal flora of the oral cavity, large intestine, conjunctiva, and skin in humans (4).

Propionibacterium 2 (especially Propionibacterium acnes) can cause bacteremia in immunocompromised individuals or endocarditis in individuals with prosthetic or damaged heart valves, conjunctivitis associated with contact lenses, or infections related to ventriculoperitoneal shunts, prosthetic joints, peritoneal dialysis, or intravascular catheters. 3 Uncommonly, it has been isolated alone, or Cutibacteria (formerly propionibacteria) are part of the normal flora of human skin and mucosal surfaces.

Cutibacterium acnes (formerly known as Propionibacterium acnes) is found briefly on the skin of neonates, but true colonization begins during the 1-3 years prior to sexual maturity. During this time, numbers of C acnes rise from fewer than 10/cm 2 to about 10 6 /cm 2 , chiefly on the face and upper thorax.

Propionibacterium acnes is often considered a contamin-ant when it grows in blood culture, akin to the growth of coagulase-negative staphylococci, Bacillus sp., and Corynebacterium sp.

2011-04-01 Propionibacterium acnes is a Gram-positive bacterium that forms part of the normal flora of the skin, oral cavity, large intestine, the conjunctiva and the external ear canal. Although primarily recognized for its role in acne, P. acnes is an opportunistic pathogen, causing a range of postoperative and device-related infections.
