Characterisation of propionibacterium acnes
Propionibacterium acnes forms part of the normal flora of the skin, oral cavity, large intestine and the external ear. Historically, P. acnes is considered to be of low virulence; however, in recent years it has been found as the aetiological agent in various pathologies including acne vulgaris, …

Propionibacterium acnes and its phages
… harbors several different microorganisms, with Propionibacterium acnes being one of the most common bacteria. This Gram-positive anaerobe has long been attributed as the cause of acne vulgaris, and is known to cause severe inflammations on orthopedic implants. However, like most bacteria, P. …

Purification and characterisation of the lipid macroamphiphiles of propionibacterium acnes.
… acne vulgaris, in addition to the presence of Propionibacterium acnes on the skin, changes in the composition of skin lipids has been identified as an important etiological factor in the development of the disease. To date, the LMAP of P. acnes has not been purified and, for this reason, the …

Role of polymorphonuclear leukocytes in the tumoricidal activity of Propionibacterium acnes
… of mice with a mixture of tumor cells and Propionibacterium acnes were investigated. Tumor cells were injected intramuscularly into Balb/c mice either alone or together with P. acnes vaccine. The tumor cells were then removed from the injection site 12 hours after injection, and transferred …

Immunotherapeutic alteration of tumor-induced suppression of interleukin 2 and 3 production by Propionibacterium acnes vaccination
… activity arising from systemically injected P. acnes is macrophage-mediated, whereas anti-tumor activity arising from locally injected P. acnes is T cell-mediated. It is possible these P. acnes-induced cytotoxic T cells arise via the Interleukin cascade. Therefore, this study investigated the …

Semiquantitative und quantitative Charakterisierung der Zytokinantwort humaner Keratinozyten nach Stimulation mit Propionibacterium acnes und Koproporphyrin III
… to be induced by an immunological reaction to Propionibacterium acnes. Objectives In the present study we examined the local host response mechanism of keratinocytes 3 and 6 h after stimulation with viable and heat- killed P. acnes. Methods The quantitative expression of cytokines was measured …

Use of cell wall-hydrolytic enzymes in studies of the reticuloendothelial-stimulatory properties of Propionibacterium acnes
Vaccines prepared from whole cells of heat-killed Propionibacterium acnes were treated with a variety of enzymes. Only two enzymes, lysozyme and a bacteriolytic enzyme from the common European limpet, Patella vulgata, were able to abrogate the splenomegaly-inducing activity of vaccines. …

A novel two-component signal transduction system in propionibacterium acnes and its association with a putative extracellular signalling peptide
Propionibacterium acnes, a resident micro-organism of human skin, is thought to be involved in the development of inflammatory acne, which is an exclusive human disease affecting more than 80% of the whole population. Quorum sensing is the regulation of gene expression in response to cell density. …

Anti-aging potential of some freshwater microalgae extracts
… testing was conducted on commensals, Propionibacterium acnes and Staphylococcus aureus. The results obtained indicate that the extracts contained phenols and sulfhydryl groupcontaining compounds that could be responsible for certain biological activities of importance to this study. …

Augmentation of Natural Killer Cell Activity by CORYNEBACTERIUM PARVUM: Involvement of Lipoxygenase Pathway
<p>The <sup>51</sup>Chromium release assay was used to measure natural killer (NK) cell activity associated with <em>Corynebacterium parvum</em> (CP) injection against YAC-1 and MBT-2 targets. The peritoneal exudate cells from intraperitoneal treatment of CP at different dosages consistently gave …
