Abstract

Insights

Rat bite fever (RBF), a rare illness from rat exposure, can lead to vertebral osteomyelitis and discitis. Prompt diagnosis and antibiotic treatment are crucial for recovery.

Area of Science:

  • Infectious Diseases
  • Bacteriology
  • Osteoarticular Infections

Background:

  • Rat bite fever (RBF) is an uncommon zoonotic illness caused by rat exposure.
  • Streptobacillus moniliformis is the typical bacterium responsible for RBF in the U.S.

Observation:

  • A case of RBF complicated by vertebral osteomyelitis and discitis is presented.
  • The patient had a history of being bitten by pet rats.

Findings:

  • The patient's symptoms significantly improved after a six-week course of cephalexin.
  • This case highlights a rare but serious complication of RBF.

Implications:

  • A detailed zoonotic exposure history is vital for diagnosing RBF.
  • Consider RBF in the differential diagnosis for patients presenting with discitis and osteomyelitis.
