[Cloverfield] When Marlena was bitten by the smaller monster, what happened to her?

In the scene, Marlena was bitten by another creature that looked like louse or mite from Clover, and she ended up exploding later on.  What exactly happened to her that led to such a violent reaction from the bite?

There is a unique chemical compound in the saliva of the human-sized parasites (HSP). The compound causes the signs and symptoms you see at first: dizziness, hemorrhaging from the eyes and nose, and vomiting blood. Eventually, the reaction with the body becomes severe--specifically in the chest cavity--causing an explosion in the central cavity of the victim.

Not much else is known at the moment; the exact mechanics behind the bites is still being researched.
