| o-alkylhomoserine synthesis catalyzed by o-acetylhomoserine sulfhydrylase in microorganisms. | an enzyme that can synthesize o-alkylhomoserine from alcohols and o-acetylhomoserine was purified from corynebacterium acetophilum. the enzyme was found to be identical to o-acetylhomoserine sulfhydrylase; a preparation that appeared homogeneous on polyacrylamide gel electrophoresis showed both o-alkylhomoserine-synthesizing and o-acetylhomoserine sulfhydrylase activities. its molecular weight was determined to be about 220,000, and it consisted of two subunits. its ph and temperature optima for ... | 1977 | 15989 |
| determination of the effective concentration of jodonal a for the disinfection of the skin and teats after milking. | the bactericidal effectivity of jodonal a in 1:10, 1:5, and 1:3 solutions was tested on human skin and on the teats of cow mammary glands. the 1:3 dilution ratio proved best for three-minute exposure. jodonal a used in this concentration in 522 cows for the post-milking disinfection of teats for 10 months exerted no harmful effect on the skin of the mammary glands. | 1976 | 16377 |
| devitalizing effect of jodonal a in vitro on bacteria subject to a short-term exposure. | in a three-minute exposure in vitro jodonal a devitalized a culture of serological group b streptococci in a 2% concentration, staphylococcus aureus in a 16% concentration, pneumococcus in a 4.5% concentration, corynebacterium pyogenes in a 2.5% concentration, pseudomonas aeruginosa in a 3% concentration, and klebsiella pneumoniae in a 2% concentration. hence jodonal a concentrations higher than 16% should be tested for udder teat disinfection after the removal of teat cups. | 1976 | 16378 |

| [gram-positive bacteria as adjuvants (author's transl)]. | gram-positive bacteria or their constituents influence the immune response in various ways. for instance: listeria monocytogenes cellwall fraction acts as b-cell mitogen, in this way enhancing a humoral immune response. corynebacterium parvum acts as a macrophage stimulant evoking maximum macrophage activation. bcg, among other things, leads to an enhancement of a t-cell response to unrelated antigens. the hypothetical therapeutic consequences are discussed. | 1978 | 96006 |
| value of acid metabolic products in identification of certain corynebacteria. | acid metabolic products of 23 strains of human and animal pathogenic corynebacteria, representing eight different species, were determined by gas chromatography. the results showed that the species examined were metabolically heterogeneous and could be presumptively identified based on the acid products produced. corynebacterium equi did not produce any acids; c. renale produced lactate; and c. pyogenes produced major amounts of lactate, variable amounts of acetate, and minor amounts of succinat ... | 1978 | 96126 |
| isolation of the l-phase variant from toxigenic corynebacterium diphtheriae c7(beta). | the l-phase variant was isolated from lysogenic strain c7(beta) of corynebacterium diphtheriae by the penicillin disk tecnnique on an agar medium containing 3.7% brain heart infusion, 3% nacl, 1.25% grycine, 1% noble agar, and 10% horse serum. the l-phase formed a "fried egg" colony; it was resistant to antibiotics that inhibit biosynthesis of bacterial cell walls but was susceptible to antibiotics that act on the protein-synthesizing system. after several transfers of the l-phase initially isol ... | 1978 | 97222 |
| cross-reactions between mycobacteria. ii. crossed immunoelectrophoretic analysis of soluble antigens of bcg and comparison with other mycobacteria. | cross-reactions between mycobacterium bovis bcg and various other mycobacteria, nocardia asteroides, corynebacterium pyogenes and listeria monocytogenes were studied by incorporating antibodies against these bacteria in the intermediate gel of a crossed immunoelectrophoretic system with bcg antigen and anti-bcg antibodies. in the bcg reference system forty-four distinct antigenic components were recorded, of which thiryt-three cross-reacted with mycobacterium tuberculosis, twenty-five with m. av ... | 1979 | 106465 |

| ocular flora in the severely burned patient. | one hundred six eyes of 53 patients with severe thermal burns were studied with serial conjunctival cultures during a four-month period. a dramatic shift of the normal conjunctival flora from the preponderance of staphylococcus epidermidis and corynebacterium to s aureus and gram-negative bacilli was observed. this commonly occurred on the fifth to sixth postburn day and represented colonization of the conjunctiva by bacteria recovered from other sites in the body. despite the high incidence of ... | 1978 | 98138 |
| evidence that the regulation of diphtheria toxin production is directed at the level of transcription. | it has been known for several decades that iron inhibits the production of diphtheria toxin by corynebacterium diphtheriae by preventing expression at maximal levels. we examined the inhibition kinetics of toxin production after the addition of either iron or rifampin to iron-limited cultures of c7 (betatox+). iron-mediated inhibition of toxin production was found to be linear within the range of 16 nm to 16 micron. the inhibition kinetics following the addition of iron or rifampin was almost id ... | 1978 | 98519 |
| studies on the occurrence of peptococcus indolicus and corynebacterium pyogenes in abscesses in swine, and on the occurrence of pc. indolicus in apparently normal skin and mucous membranes of piglets. | pc. indolicus was isolated from 42.7% and cb. pyogenes from 48.7% of 150 pus-samples from abscesses in pigs (slaughter-house material, table i). in 41 specimens the two organisms were found together. further, pc. indolicus was demonstrated in 22.4% of 290 swabs from apparently normal skin and mucous membranes of piglets (autopsy material, table ii). by gel diffusion analysis the strains of pc. indolicus were referred to the serotypes b, c, d, e, or f. the type distribution (table iii) possibly r ... | 1978 | 98755 |
| [antitumor activity of the bacterial walls of br. abortus 99]. | a brief chronologic survey is made of investigations that reveal that the bacterial cell walls and their chemical components exhibit antitumoral activity. discussed is the problem which are the constituents of the bacterial wal and what is the mechanism through which such effects are produced. the conclusion is drawn that some peptides participating in the structure of the bacterial wall after their release in body stimulate the macrophages and thus confer antitumoral activity to them. | 1978 | 98899 |
| isoprenoid quinones in the classification of coryneform and related bacteria. | menaquinones were the only isoprenoid quinones found in 85 of the 95 coryneform bacteria examined. dihydromenaquinones having nine isoprene units were the main components isolated from corynebacterium bovis, from other glutamic acid-producing strains, and from arthrobacter globiformis and related species. dihydromenaquinones with eight isoprene units were found in brevibacterium linens, the remaining corynebacterium species and strains probably belonging to the genus rhodococcus. tetrahydromenaq ... | 1979 | 107269 |

| protection against chemotherapy toxicity by iv hyperalimentation. | a prospective randomized trial was conducted comparing the addition of iv hyperalimentation (ivh) to corynebacterium parvum, isophosphamide, and adriamycin (cia) chemoimmunotherapy in 26 patients with extensive squamous cell lung cancer. thirteen patients were entered in each treatment arm of the study and ivh was administered before and after the first course of cia for a total of 31 days. the major dose-limiting toxic effect of cia was leukopenia. less myelosuppression was observed for the pat ... | 1978 | 99235 |

| [antagonistic and bacteriocinogenic activity of meningococci]. | antagonistic and bacteriocinogenic activity was studied in 169 strains of meningococci of various serological groups and with different localization in the human organism at the time of isolation. bacteriocinogenic activity was revealed in all the meningococcus strains (by delayed antagonism method), and, in addition, antagonistic activity was found in 100 strains. the inhibitory activity was the greatest in meningococci isolated from the cerebrospinal fluid. the data obtained suggest an importa ... | 1978 | 99921 |
