Educational video describing the condition of rat bite fever.
Rat-bite fever is an illness caused from bacteria transmitted by rodents. The condition goes by many names but it is typically transmitted by a rat. The disease can be passed from the urine or feces of an infected rodent but it is typically caused due to the animal’s bite. The bacteria responsible for rat-bite fever is found in the mouth, nose and respiratory tract of many rats and sometimes infection from the bite can be fatal. It is rare disease typically spread by infected rodents however pets such as dogs or cats that are exposed to these animals can also carry the disease and infect humans.
There are two types of gram-negative bacteria that can cause the infection: streptobacillosis moniliformis and spirillum minus.
Symptoms occur 3-10 days after exposure, however they can be delayed up to several weeks. Symptoms include: chills/fever, headache, muscle aches, vomiting, painful swelling of the joints (polyarthralgia), fatigue, rash. Symptoms are nonspecific and can be confused with other diseases. It is a difficult diagnosis and the diagnosis could be delayed. Here is a patient MRI of the right side shoulder. The patient had documented infection of the right shoulder proven to be caused by rat-bite fever. The patient had incision and drainage of the right shoulder.
Treatment is usually penicillin or its derivative. A good prevention program to avoid exposure to infected animals. The mortality rate is about 13% if not treated.
The CDC states that those at higher risk of contracting the illness are people with pet rats or those who work with rats in laboratories, pet stores or people who live in rat-infested buildings. People who handle rodents or clean up after them should wash their hands regularly, as well as wear protective gloves and avoid placing their hands to the mouth after being in contact with rodents. All rodents are potential carriers of the bacteria. Children under the age of 5, pregnant women and people with weakened immune systems should consider not having a rat as a pet.
