| determination of catalase, peroxidase, and superoxide dismutase within the genus legionella. | we examined 40 strains of legionella for reduced-oxygen scavenging enzymes. using a simple reaction chamber with a swinney filter for the beers and sizer assay, we determined the catalase activity of live cells grown on buffered charcoal-yeast extract agar. for 29 strains of legionella pneumophila, the apparent first-order rate constants for catalase ranged from 0.000 to 0.005. similarly, low values ranging from 0.001 to 0.005 were observed for legionella wadsworthii, legionella oakridgensis, an ... | 1984 | 6490828 |
| clinical laboratory differentiation of legionellaceae family members with pigment production and fluorescence on media supplemented with aromatic substrates. | a systematic study of pigment production (browning) and fluorescence (extracellular yellow-green and intracellular blue-white) by nine legionellaceae species was performed. a total of 56 strains representing tatlockia micdadei (pittsburgh pneumonia agent), legionella pneumophila, legionella jordanis, legionella longbeachae, legionella oakridgensis, legionella wadsworthii, fluoribacter bozemanae, fluoribacter gormanii, and fluoribacter dumoffii could be separated on media supplemented with tyrosi ... | 1984 | 6547453 |
| legionella wadsworthii species nova: a cause of human pneumonia. | a new species of legionella that caused pneumonia in a patient with chronic lymphocytic leukemia has been characterized. the legionella wadsworthii species nova is proposed for this bacterium. the type strain is wadsworth 81-716a (american type culture collection 33877). the new species differs phenotypically from l. pneumophila in that the predominant cellular fatty acid is methyl-12-methyltetradecanoic acid (a-15:0) rather than methyl-14-methylpentadecanoic acid (i-16:0), and in its failure to ... | 1982 | 6756238 |
