Utilization of hemin and hemoglobin by Vibrio vulnificus biotype 2.
The eel pathogen Vibrio vulnificus biotype 2 is able to use hemoglobin (Hb) and hemin (Hm) to reverse iron limitation. In this stud, the adjuvant effect of both compounds on eel pathogenicity has been evaluated and confirmed. Further, we have studied the heme-iron acquisition mechanism displayed by this bacterium. Whole cells were capable of binding Hb and Hm, independently of (i) iron levels i...

متن کاملFirst isolation and identification of Vibrio vulnificus (biotype 2) from cultured beluga, Huso huso in Iran
By decreasing of sturgeon stocks in the Caspian Sea, the culture of different sturgeon species especially Huso huso was increased in Iran. Under stress conditions sturgeon can easily be infected by several opportunistic pathogens. In June 2011, mortality happened in 25-28°C water temperature, in one of the most important cultured sturgeon farms in Mazandaran province in the north of Iran. The m...
متن کاملDraft Genome Sequence of Environmental Bacterium Vibrio vulnificus CladeA-yb158
We report the genome sequence of the environmental Vibrio vulnificus biotype 1_cladeA. This draft genome of the CladeA-yb158 strain, isolated in Israel, represents this newly emerged clonal group that contains both clinical and environmental strains.
متن کاملSpontaneous quinolone resistance in the zoonotic serovar of Vibrio vulnificus.
This work demonstrates that Vibrio vulnificus biotype 2, serovar E, an eel pathogen able to infect humans, can become resistant to quinolone by specific mutations in gyrA (substitution of isoleucine for serine at position 83) and to some fluoroquinolones by additional mutations in parC (substitution of lysine for serine at position 85). Thus, to avoid the selection of resistant strains that are...
