[changes in the physiologic properties of a chemostat culture of propionibacterium shermanii during growth limitation by a deficiency of sodium lactate].a chemostat curve has been constructed for changes in the propionibacterium shermanii population density with an increase in the flow rate of the medium from 0.04 to 0.55 h-1 upon limitation of the growth with sodium lactate deficiency. the curve differs from the classic chemostat curve described with the monod equation, thus indicating changes in metabolism at different growth rates. fermentation of lactate to acetic and propionic acids by the culture is most complete at low flow rates of the m ...197993687
quantitation of skin bacteria: lethality of the wash solution used to remove bacteria.a widely used technique for the quantitative removal of bacteria from the skin uses a detergent, triton x-100 (p, t-octylphenoxynonaethoxyethanol), to remove and suspend the bacteria. we determined the half-life for the survival of five common skin bacteria suspended in the solution. the shortest-lived was streptococcus pyogenes with a half-life of 0.9 hours. all of the others (propionibacterium acnes, staphylococcus epidermidis, staphylococcus aureus, and klebsiella pneumoniae) had half-lives o ...197993373
adjvant treatment of tongue and floor of the mouth cancers.since january 1974, 95 patients with anterior tongue and floor of the mouth cancers were included in a randomized trial. after stratification according to staging and initial treatment, one-third of the patients received chemotherapy for 2 years (methotrexate 400 mg followed by citrovorum factor 100 mg + bleomycin 60 mg/week, during the first 15 weeks), one-third of the patients received immunotherapy with weekly c. parvum injections during 2 years, while the remaining third did not receive any ...197888754
chemotherapy of advanced head and neck cancer with methotrexate, bleomycin, and cis-diamminedichloroplatinum ii in an effective outpatient schedule.thirty-one patients with advanced cancer of the head and neck, twenty-six of whom had failed prior irradiation, were treated with an out-patient chemotherapy regimen combining methotrexate, bleomycin, and cis-diamminedichloroplatinum (ii). the overall response rate among evaluable patients was 61%, with 22.5% complete remission. if 6 additional patients not completing 3 weeks of treatment are included, the response rate was 51.4%. the median duration of partial remission was 3 months, but none o ...197988256

role of mononuclear infiltrating cells in pathogenesis of hepatitis.mice that have been injected with corynebacterium parvum have mononuclear-cell infiltrates in the liver lobules. in such mice a small dose of lipopolysaccharide endotoxin produced a lethal hepatitis, with high serum-transaminase concentrations, glycogen depletion, and hypoglycaemia. it is suggested that lipopolysaccharide triggers the release from the infiltrating mononuclear cells of factors toxic for hepatocytes. similarly certain parasitic and virus infections and graft-versus-host reactions ...197880531
abscesses of the frontal lobe of the brain secondary to covert dental sepsis.the bacterial species found in pus aspirated from brain abscesses in two patients were typical of those found in dental sepsis. subsequently apical-root abscesses were demonstrated in the upper jaws of both patients. this evidence strongly suggests that these cerebral abscesses were secondary to dental sepsis which could have spread from the teeth to the frontal lobes by several possible antaomical pathways.197879867

metronidazole and acne.the strong activity of metroindazole against obligate anaerobes suggested that the organism proprionobacterium acnes and the disease acne vulgaris might respond to treatment with this drug. thirty-three clinical isolated of p. acnes were tested and found to be highly resistant to metronidazole. prospects for its successful use in acne are remote.197660028
study of elastolytic activity propionibacterium acnes and staphylococcus epidermis in acne vulgaris and in normal skin.histopathological sections of anetoderma-like scars from 10 patients with acne vulgaris showed a selective absence of elastic fibers around pilosebaceous follicles. this finding is similar to the histologic changes of "perifollicular elastolysis" reported by varadi. bacteria isolated by anaerobic and aerobic cultures of swabs of the skin surface and pus of these 10 patients, 12 others with active acne vulgaris and 8 normal subjects were studied with particular attention to staphylococcus epiderm ...197660023
biological purpose of acne.it is argued that the close endocrine control of human sebaceous glands and the likely effects of acne on selection indicate that both gland and disease have persisted because they are biologically useful. two possibilities are proposed: sebum may provide precursor substrates for metabolism and synthesis by the epidermis of compounds of both local and systemic importance; and the adjuvent properties of corynebacteria which colonise the active sebaceous glands of acne may facilitate certain gener ...197658315

the role of bacteroides melaninogenicus and other anaerobes in periodontal infections.recent taxonomic and anatomical studies of dental plaque associated with periodontal health and disease have demonstrated that differences in the microbial populations in plaque may be responsible for the initiation and progression of disease. the consistent isolation of large numbers of anaerobic and capnophilic bacteria from the depths of periodontal lesions has suggested an important role for these organisms. bacteria that have been isolated include capnocytophaga (bacteroides ochraceus), oth ...197944923
production of hyaluronidase by propionibacteria from different origins.114 strains of anaerobic and microaerophilic coryneform bacteria from different origins were investigated for production of free extracellular hyaluronidase (hyaluronate glycanohydrolase, ec 3.2.1.36). a quantitative technique was applied measuring the release of n-acetyl-glucosamine groups from purified human potassium hyaluronate. the strains belonged to the following species: propionibacterium acnes, p. avidum, p. granulosum, p. lymphophilum, the formerly so-called corynebacterium parvum, p. ...197944604
[physiologo-biochemical features of the growth and development of propionibacterium shermanii in egg albumin].propionibacterium shermanii was shown to be able of growing in such an unusual substrate as egg albumen. incubation of the bacterium in egg albumen results in complete utilization of free carbohydrates in this substrate and accumulation in it of such bacterial metabolites as vitamins b2 and b12, free amino acids, bacterial protein, acetic and propionic acids which favour conservation of egg albumen. the bacterium does not possess proteolytic activity and does not utilize albumen; in the conditio ...197943462
purification and partial characterization of hyaluronate lyase (ec 4.2.2.1) from propionibacterium acnes.hyaluronidase from propionibacterium acnes has been purified 13,000-fold from the culture supernatant to homogeneity (as determined by polyacrylamide disc gel electrophoresis). the molecular weight of the purified enzyme was 85,110 as determined by gel filtration. the purified enzyme had a ph optimum at 6.4, was stable between ph 5 and 5.8 and was completely inactivated after 15 min at 50 degrees c. preliminary studies suggested that the enzyme is active against chondroitin 4- and 6-sulphates, b ...197943356
