"The rabid guinea pig is an unusually rare occurrence. The guinea pig was a pet of a resident of Madison County. While being allowed to exercise in a backyard during daylight hours the rodent was attacked by a raccoon. The owner heard the pet squeal and as she approached, the raccoon ran off. There were no visible wounds on the pet."
"Twenty six days later the owner was bitten on the clavicle while holding the pet. Because rabies was originally not suspected, an additional eight days elapsed before the pet was euthanized and submitted for testing. The positive diagnosis was confirmed by isolation of the virus in cell culture and antigenic typing. The variant was identified as the raccoon strain of rabies virus. Further analysis of the distribution of rabies virus in the organs of the guinea pig revealed extensive proliferation of the virus into many areas of the body, including the salivary glands. The owner received rabies prophylaxis."
