| a comparison of the distribution of extracellular proteins produced by the protease-secreting organism aeromonas salmonicida during aerobic and anaerobic growth. | aeromonas salmonicida was grown aerobically and anaerobically in supplemented 3% (w/v) tryptone soya broth medium for 24 h at 25 degrees c. although the bacterial density achieved was 4.9 times higher in the aerobic culture, the exoprotein produced per unit of bacterial dry weight was only 1.9 times higher than in the anaerobic culture. however, the protease activity of the exoprotein showed a marked reduction anaerobically, being only one-tenth of that of the exoprotein produced aerobically. th ... | 1986 | 3322167 |
| does aeromonas hydrophila preferentially colonize the bowels of patients with hematologic malignancies? | weekly cultures of stools from neutropenic patients and bone marrow transplant recipients yielded aeromonas hydrophila from 8% of 88 patients over a 2-yr period. during this time stools in the routine enteric laboratory yielded a. hydrophila in 0.24% of 1632 patients. although the patient groups and culture methods were not directly comparable, this significant difference in isolation rate (p less than 0.001) may reflect a higher colonization rate in the immunocompromised patient. | 1987 | 3319373 |
| [aeromonas spp. as pathogens in human infections: diagnosis and clinical significance]. | aeromonads have been described as causative agents in a wide variety of infections in immunosuppressed as well as in immunocompetent patients. it is still controversial whether or not some or all three currently recognized species have to be considered as enteropathogenic. clinical and epidemiological data are incomplete and contradictory although laboratory diagnosis does not cause real problems. | 1987 | 3315971 |
