Unformatted text preview: coagulates blood (this same enzyme is what activates the Staph Latex Test in lab). Clots can wall off growing organism from blood and phagocytes, although it limits the spread of the organism. 4. Kinases: Streptokinase a good example. These break up clots to allow for spread of the organism. Streptokinase used medically to dissolve coronary clots in a coronary attack. 5. Hyaluronidase: Dissoves cellular cement-- responsible for blackening of wounds as in gangrene infections. 6. Collagenase: Breaks down collagen in connective tissue. Gelatin extracted from collagen. 7. Sideophores: scavage iron out of body fluids. 8. Invasins: These enzymes can act on actin protein to rearrange the cellular skeleton so that the pathogen can penetrate cells (Salmonella can do this)....
