only the kamodo dragans have that deadly bacteria in their saliva, shes only dangerous when shes hungry, jumps at anything that she thinks is food. this one is know to be the most aggresive of monitors, took me 3 years to tame. I have a few friends that have scars from her, only because they where drunk trying to play with her. Its fun when I have partys and see who has the balls to feed her.
Before I wrote that reply...I looked it up to be sure I was right. I found this and several other articles.
"Capturing Nile monitors is definitely not for the faint hearted. Their bites can prove nasty and even fatal to humans and other animals, due to the fact that although they are not venomous, they do carry a variety of germs and potentially lethal pathogens in their saliva and medical treatment should be sought immediately. In addition, although they currently attempt to avoid people, if cornered they rear-up on their hind legs, hiss and lash out with their sharp teeth, claws and strong tails."
