Rat-bite fever is a rare disease spread by infected rodents.
Causes:
The source of the infection is usually a rat. Other animals that may cause infection include squirrels, weasels, and gerbils.
Rat-bite fever can be caused by the two different bacteria, Streptobacillus moniliformis or Spirillum minus, both of which are found in the mouths of rodents.
Most people get rat-bite fever through contact with urine or secretions from the mouth, eye, or nose of an infected animal. This most commonly occurs though a bite, yet some cases may occur simply through contact with these secretions.
Symptoms:
Symptoms depend on the bacteria that caused the infection.
Symptoms due to Streptobacillus moniliformis may include:
- Chills
- Fever
- Joint pain, redness, or swelling
- Open sore at the site of the bite
- Rash -- may be red/purple plaques
