Viruses specifically infecting bacteria, or bacteriophages, are the most common biological entity in the biosphere. As such, they greatly influence bacteria, both in terms of enhancing their virulence and in terms of killing them. Since the first identification of bacteriophages in the beginning of the 20th century, researchers have been fascinated by these microorganisms and their ability to e...

Propionibacterium acnes was isolated from postoperative specimens from nine neurosurgical patients. The role of P. acnes in postneurosurgical infection is discussed.

Generally the so-called Meyerhof-Embden scheme is considered to be the major pathway of hexose dissimilation by members of the genus Propionibacterium. Two lines of evidence supporting this premise are the isolation, coupled with a demonstration of their utilization, of several of the intermediates of glycolysis (Wood, Stone, and Werkman, 1937; Werkman, Stone, and Wood, 1937; Barker and Lipmann...

Autolysis is self-degradation of the bacterial cell wall that results in the release of enzymes and DNA. Autolysis of starter bacteria, such as lactococci and propionibacteria, is essential for cheese ripening, but our understanding of this important process is limited. This is mainly because the current tools for measuring autolysis cannot readily be used for analysis of bacteria in mixed popu...

The primary objective of this study was to investigate the survival rate three species encapsulated bacteria (Propionibacterium acidipropionicici, Propionibacterium freudenreichii, and thoenii) in model solutions designed simulate acidity levels found within human gastrointestinal tract. capsules were prepared by extrusion from gelatin sodium alginate a 1:1 ratio on laboratory encapsulator. use...

While mutans streptococci have long been assumed to be the specific pathogen responsible for human dental caries, the concept of a complex dental caries-associated microbiota has received significant attention in recent years. Molecular analyses revealed the complexity of the microbiota with the predominance of Lactobacillus and Prevotella in carious dentine lesions. However, characterization o...

A case of septicemia caused by Propionibacterium granulosum in a compromised patient is described. The patient responded to ampicillin therapy. Detailed antibiotic susceptibility data are presented.
