the effects of a microbial inoculant (containing propionic and lactic acid bacteria) and formic acid onchemical composition, ruminal degradability of dry matter (dm) and nutrient digestibility of corn silage wereexamined. whole-plant corn was ensiled for 60 days in plastic polyethylene bags, and three treatments werecompared, 1: control (no additive), 2: propionibacterium acidipropionici plus l...

Sheep and human erythrocytes, partially processed by Staphylococcus aureus or Clostridium perfringens, were susceptible to lysis in the presence of Propionibacterium acnes. P. acnes liberated a lipase that was detected on Tween 80 agar and also on phospholipase C-precipitated egg yolk agar. Such a lipase might have contributed in the process of an intensified cellular lysis. Similar reactions w...

Perioperative shoulder infections involving Propionibacterium acnes can be difficult to identify in a patient who presents with little more than pain and stiffness in the postoperative period. Although indolent in its growth and presentation, infection of the shoulder with P acnes can have devastating effects, including failure of the surgical intervention. This article reviews the importance o...

Correspondence Propionibacterium propionicus Infection in Chronic Granulomatous Disease Sir—Bourdeaut et al. [1] recently described 2 pediatric patients with chronic granulomatous disease (CGD) who developed chest infections caused by Pro-pionibacterium acnes. We describe a 7-year-old boy with CGD who developed a Propionibacterium propionicus infection. CGD is an inherited disease caused by def...

BACKGROUND Propionibacterium acnes (P. acnes) is a common microbe of the skin and mucosal surfaces rarely considered a true pathogen. However, it has been reported to cause serious infections. Subsequent ongoing low-grade antigenaemia may, in turn, lead to an immune-mediated glomerulonephritis with various renal histologies including that of membranoproliferative glomerulonephritis (MPGN). ME...

Propionibacterium acnes P13 was isolated from human feces. The bacterium produced a particulate nitrate reductase and a soluble nitrite reductase when grown with nitrate or nitrite. Reduced viologen dyes were the preferred electron donors for both enzymes. Nitrous oxide reductase was never detected. Specific growth rates were increased by nitrate during growth in batch culture. Culture pH stron...
