Intestinal parasites, or worms, are a plague to both dogs and cats. Most pets will harbor worms at some point in their lifetime. Puppies and kittens have a high incidence of intestinal parasites, and most receive de-worming treatment as part of their routine care. Roundworms, hookworms, and whipworms are the most common culprits of these infections.

URBANA - For over 130 species of birds, getting bitten by a mosquito carrying the West Nile virus can be fatal. And, although crows and jays appear to be hardy, aggressive birds, there is something about their immune system that makes them "differentially susceptible to the virus" said Jeff Brawn, a University of Illinois researcher. Brawn has been working with medical entomologists for the last year to study the effects of the virus on bird populations. He hopes to study how the virus will cause an evolutionary change in the crow’s immune system.
