Vibrio vulnificus was isolated from a bacteremic patient. This strain, together with other isolates of V. vulnificus, was compared with V. alginolyticus, V. fluvialis, and V. parahaemolyticus with regard to growth characteristics on enteric agar media (enabling isolation and identification) and production of exoenzymes which could correlate with invasive potential. V. vulnificus grew well on Ma...
We evaluated the genetic and physiological variability of Moniliophthora perniciosa obtained from healthy and diseased branches of cacao (Theobroma cacao) plants. The diversity of the isolates was evaluated by RAPD technique and by studies of virulence and exoenzyme production. The genetic variability of endophytic and pathogenic M. perniciosa was evaluated in association with pathogenicity ass...
We have previously shown that Helicobacter pylori specifically binds to a glycerolipid species preferentially found in the antrum of the human stomach. We now show by high-pressure liquid chromatographic analysis that this species is a form of phosphatidylethanolamine and that H. pylori specifically binds to bona fide phosphatidylethanolamine as detected by a thin-layer chromatogram overlay pro...
Intracellular targeting of the Pseudomonas aeruginosa toxins exoenzyme S (ExoS) and exoenzyme T (ExoT) initially results in disruption of the actin microfilament structure of eukaryotic cells. ExoS and ExoT are bifunctional cytotoxins, with N-terminal GTPase-activating protein (GAP) and C-terminal ADP-ribosyltransferase activities. We show that ExoS can modify multiple GTPases of the Ras superf...
Some bacterial products possess multiple immunomodulatory effects and thereby complex mechanisms of action. Exogenous administration of an important Pseudomonas aeruginosa virulence factor, exoenzyme S (ExoS) induces potent monocyte activation leading to the production of numerous proinflammatory cytokines and chemokines. However, ExoS is also injected directly into target cells, inducing cell ...
