Vibrio cholerae haemolysin: genetic constitution and biotype
voltage-gated K channels in other cell types [Ba 2 mM; Cs 5 mM; TEA (tetraethylammonium) 20 mM; EGTA 1 mM) (Lew & Ferreira, 1978; Egan et ul., 1987) did not, however, alter ouabainand bumetanide-insensitive K uptake. The substitution of CH,SO, for CI in the incubation medium reduced the residual K uptake by about 18%, suggesting that a Cldependent K transport pathway similar to that observed in...
متن کاملSurvival of Vibrio anguillarum and Vibrio salmonicida at different salinities.
The fish pathogenic bacteria Vibrio anguillarum and V. salmonicida showed the capacity to survive for more than 50 and 14 months, respectively, in seawater microcosms. A salinity of 5% proved lethal to V. anguillarum harvested in the late-exponential growth phase, whereas a salinity of 9% was lethal to the bacterium after it had been starved at a salinity of 30% for 67 days. The lethal salinity...
متن کاملIron Acquisition Strategies of Vibrio anguillarum
The hemorrhagic septicemic disease vibriosis caused by Vibrio anguillarum shows noticeable similarities to invasive septicemia in humans, and in this case, the V. anguillarum-host system has the potential to serve as a model for understanding native eukaryotic host-pathogen interactions. Iron acquisition, as a fierce battle occurring between pathogenic V. anguillarum and the fish host, is a piv...
متن کاملPhage Therapy as an Approach to Prevent Vibrio anguillarum Infections in Fish Larvae Production
Fish larvae in aquaculture have high mortality rates due to pathogenic bacteria, especially the Vibrio species, and ineffective prophylactic strategies. Vaccination is not feasible in larvae and antibiotics have reduced efficacy against multidrug resistant bacteria. A novel approach to controlling Vibrio infections in aquaculture is needed. The potential of phage therapy to combat vibriosis in ...
متن کاملContact-haemolysin production by entero-invasive Escherichia coli and shigellae.
Entero-invasive Escherichia coli (EIEC) and shigellae were tested for contact-haemolysin (CH) with red blood cells (RBCs) of guinea-pig, rabbit, rat, mouse, monkey, man, sheep and chicken; all bacteria showed the best lysis with guinea-pig RBCs. The best culture medium for CH activity of shigellae was tryptic soy broth, and for EIEC it was casamino acid-yeast extract broth with 1 mM CaCl2. CH p...
