Re: Dromaeosaur disease resistance


      Disease organisms relying on healthy hosts (micro-organisms in a dinosaur's gut assisting in digestion, e.g.) are different from pathogens dangerous to a host by becoming more toxigenic (and being able to mutate in just a few weeks, e.g., and share genetic data quickly). A dromaeosaur eating rotting flesh, or living animals infected  with virulent diseases, necessarily would have to possess highly efficient immune systems (the carcass could be in water, and waterborne diseases likewise could pose a hazard to our predator).
IMHO actual predators, birds or mammal often choose the sick animal to attack because it's the most easy to catch, it must have been the same for dinosaurs.
Idunnow why they could have caught the prey's deseases easier than lions, hyenas,... And does a vulture get ill while eating rotting meat?
The "mad cow desease" isn't a good example, it isn't natural for an herbivore to feed on meat.
