General Information | Comment | Organism |
---|---|---|
physiological function | growth studies demonstrate that Edwardsiella ictaluri is unable to grow at pH 5 in the absence of urea but is able to elevate the environmental pH from pH 5 to pH 7 and grow when exogenous urea is available | Edwardsiella ictaluri |
physiological function | urease is required for proliferation and virulence and for intracellular replication. Intracellular replication of wild-type Edwardsiella ictaluri is significantly enhanced when urea is present, indicating that urease plays an important role in intracellular survival and replication, possibly through neutralization of the acidic environment of the phagosome | Edwardsiella ictaluri |
