| colonization of an amputation site by flavobacterium odoratum after gentamicin therapy. | flavobacterium odoratum was isolated from the stumps of the amputated toes of a debilitated patient. gentamicin therapy and the poor state of health of the patient provided suitable conditions for this gentamicin-resistant species to multiply. when the gentamicin therapy was stopped, and as the patient's heal improved, f. odoratum gradually disappeared to be replaced by staphylococcus aureus. this appears to be the first report of the isolation of f. odoratum in australia, and it indicates the p ... | 1979 | 530210 |
| chloramphenicol resistance of three different flavobacteria. | the chloramphenicol resistance of some flavobacteria was investigated comparatively. this resistance can be explained either by acetylation of chloramphenicol to o-acetylchloramphenicol via constitutively formed acetyltransferases, followed by cometabolic degradation (strain cb 60), or by limited uptake and total degradation (strain cb 6) by inducible enzymes or by other mechanisms (f. devorans). the mechanisms of resistance, cm-acetylation, cm-degradation and limited uptake are discussed. | 1979 | 541254 |
| evaluation of a class iii biological safety cabinet for enclosure of an ultracentrifuge. | an evaluation of a special safety cabinet housing a high-speed centrifuge was made. the cabinet enclosed both the top access port and the drive and pumping machinery of the centrifuge. a titanium rotor was loaded with tubes containing a bacterial culture, weakened, and driven until rotor rupture occurred. there were several bent and broken components in the centrifuge, and bacteria leaked from the vacuum chamber. although the forces were sufficient to displace the cabinet, none of the test bacte ... | 1979 | 543704 |
