TABLE 3.
Expression of virulence factors in V. vulnificus wild-type strain C7184o and rpoS mutant strain AH1
| Virulence factor | Expressiona of virulence factor by strain:
|
|
|---|---|---|
| C7184o | AH1 | |
| Albuminase | + | − |
| Caseinase | + | − |
| Collagenase | + | +/− |
| Elastase | + | − |
| Gelatinase | + | +/− |
| Hemolysin | + (α) | + (α) |
| Lipase | + | + |
| Mucinase | + | + |
| Phospholipase | + | + |
Symbols: +, expressed; −, not expressed; +/−, activity was 35 to 40% less than the activity in the wild type on the basis of clearing zone size; + (α), alpha hemolysis.
