| chronic granulomatous disease of childhood and chromobacterium violaceum infections in the southeastern united states. | patients with chronic granulomatous disease are predisposed to infections by catalase-positive organisms in the environment. chromobacterium violaceum is a catalase-positive bacterium whose saprophytic source in this country is the subtropical soil and water of the southeastern united states. two patients with chronic granulomatous disease, followed at the national institutes of health in maryland, acquired c. violaceum infections in florida. all 10 cases previously reported were acquired in flo ... | 1982 | 7092006 |
| anti-quorum sensing activity of medicinal plants in southern florida. | bacterial intercellular communication, or quorum sensing (qs), controls the pathogenesis of many medically important organisms. anti-qs compounds are known to exist in marine algae and have the ability to attenuate bacterial pathogenicity. we hypothesized that terrestrial plants traditionally used as medicines may also produce anti-qs compounds. to test this hypothesis, 50 medicinal plants from southern florida were screened for anti-qs activity using two biomonitor strains, chromobacterium viol ... | 2006 | 16406418 |
