vibrio vulnificus induces macrophage apoptosis in vitro and in vivo.in this study, we compared the apoptotic activities of clinical and environmental isolates of vibrio vulnificus toward macrophages in vitro and in vivo. the clinical isolates induced apoptosis in macrophage-like cells in vitro and in macrophages in vivo. this suggests that macrophage apoptosis may be important for the clinical virulence of v. vulnificus.200312496206
identification of genetic loci required for capsular expression in vibrio vulnificus.transposon mutagenesis of an encapsulated, virulent strain of vibrio vulnificus 1003(o) led to the identification of four genetic regions that are essential to capsular polysaccharide (cps) expression and virulence. of the four regions, three are believed to be part of a capsule gene locus comprised of biosynthesis, polymerization, and transport genes clustered on a single chromosomal fragment. genes indicating a wzy-dependent system of polymerization and transmembrane export are present, sugges ...200312595419
characterization of microbial communities from coastal waters using microarrays.molecular methods, including dna probes, were used to identify and enumerate pathogenic vibrio species in the chesapeake bay; our data indicated that vibrio vulnificus exhibits seasonal fluctuations in number. our work included a characterization of total microbial communities from the bay; development of microarrays that identify and quantify the diversity of those communities; and observation of temporal changes in those communities. to identify members of the microbial community, we amplified ...200312620025
histamine-releasing reaction induced by the n-terminal domain of vibrio vulnificus metalloprotease.a zinc metalloprotease secreted by vibrio vulnificus, an opportunistic human pathogen causing septicemia and wound infection, stimulates exocytotic histamine release from rat mast cells. this protease consists of two functional domains: the n-terminal domain that catalyzes proteolytic reaction and the c-terminal domain that promotes the association with a protein substrate or cell membrane. like the intact protease, the n-terminal domain alone also induced histamine release from rat peritoneal m ...200312628443
isolation of mutants of vibrio anguillarum defective in haeme utilisation and cloning of huva, a gene coding for an outer membrane protein involved in the use of haeme as iron source.the isolation of vibrio anguillarum mutants lacking the ability to use haemin and haemoglobin as the only iron sources, as well as the identification of a gene involved in haeme utilisation are described. one of the isolated mutants defective in haeme utilisation lacked an iron-regulated outer membrane protein of 79-kda. although growth on haeme as iron source was completely abolished, the haemin and haemoglobin binding activities remained intact in the mutant, suggesting that the absent protein ...200312647036
