Bats were the most frequently reported rabid wildlife species (33% of all animal cases during 2018), followed by raccoons (30.3%), skunks (20.3%), and foxes (7.2%). The Virginia opossum is resistant to snake venom, making these venomous animals a good source of food. Here in Illinois, the opossum can prey on southern and northern copperheads and the timber rattlesnake. Opossums help keep a clean neighborhood with low risk of developing and spreading rabies! Rabies is a viral zoonotic neuroinvasive disease which causes inflammation in the brain and is usually fatal. Rabies, caused by the rabies virus, primarily infects mammals.In the laboratory it has been found that birds can be infected, as well as cell cultures from birds, reptiles and insects. Animals with rabies suffer deterioration of the brain and tend to behave bizarrely and often.
In fact, because of their low body temperature (94-97 degrees F), it is believed that the rabies virus cannot survive and replicate in the opossum.

While no wild animal is entirely immune to rabies and a few cases of opossums with it have been documented, finding one with the disease is extremely rare. Marsupials like opossums have a lower temperature compared to other. Venom Resistant – As if their resistance to rabies wasn’t enough, opossums are also immune to some venomous snake bites. The only snake they are not immune to is the coral snake. These super powered predators will hunt and eat venomous snakes if given the opportunity! Habitat of the Opossum
Rabies. People often mistake the open-mouth hissing and drooling behavior of opossums as a sign of rabies. However, this is just a bluffing behavior that opossums use as a defense mechanism. In fact, rabies is extremely rare in opossums, perhaps because they have a much lower body temperature compared to other warm-blooded animals. Resources Remarkably Rabies Resistant Although it happens on very rare occasions, opossums do not typically carry the rabies virus. This contrasts starkly with many similarly-sized animals that have carnivorous or omnivorous diets, such as skunks, foxes and raccoons, which are important rabies reservoirs. The opossum (Didelphis virginiana) is the only native North American marsupial.Marsupials are distinguished by their abdominal pouch used for carrying their young. The opossum is not native to California but was introduced in San Jose in 1910 from the east coast of the United States and has now become well established throughout much of the state.
Opossums are amazingly resistant to rabies. Hissing, drooling and swaying are part of the opossum's bluff routine. It is intended to scare away potential predators, yet it looks just like rabies and is the reason people can be convinced they're seeing rabid opossums when they're not. The opossum is a known carrier of the rabies disease. Rabies is an acute disease usually transmitted by the bite of an infected animal. All warm-blooded animals are susceptible to the rabies virus, but most reported cases are from dogs, cats, and bats. Once infected, the virus affects the brain before spreading to other body organs. Opossums are more resistant to rabies & distemper than any other mammal! Viral diseases are practically unheard of in Opossums due to their low body temperature & strong immune system! Many people see the Opossum as a nuisance animal, however, these marsupials are incredible creatures & very beneficial to have around as they eat insects & rodents.
This is because opossums, as marsupials, have a lower core body temperature, 95 degrees F, than the placental mammals that are more susceptible to rabies have. The Virginia opossum (Didelphis virginiana), commonly known as the North American opossum, is the only marsupial found north of Mexico. In the United States, the animal is typically referred to simply as a possum.It is a solitary and nocturnal animal about the size of a domestic cat.It is a successful opportunist.It is familiar to many North Americans as they frequently inhabit settled areas.
