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.
