Sick raccoons are nothing new in northern California, where distemper is fairly common among them. But some don't fit that pattern for raccoon deaths, and new laboratory studies have found out why.
Sometimes, researchers have an idea of what they will find when they begin their investigations. This was not such a case, says Dr. Patricia Pesavento, a pathologist at the UC Davis School of Veterinary Medicine. In fact, their findings surprised everyone involved.
Now that the pathology for the brain tumors has been identified, Melanie Piazza at WildCare in San Rafael says they can incorporate that knowledge in their treatment of any ailing raccoons they receive.
