Haverhill fever and rat-bite fever are closely-related syndromes caused by Streptobacillus moniliformis. This infection is characterized by the abrupt onset of fever with rigors, myalgias, headache, polyarthritis, and rash. We report a case of infection with S. moniliformis that manifested as acute polyarthritis with involvement of the spine. To our knowledge, involvement of the spine has not been reported previously with this infection. Diagnosis can be particularly difficult in the absence of fever or obvious exposure to rodents, as in our case. A high degree of awareness is necessary to make the diagnosis of this potentially fatal infection, which is easily treatable.

A 24-year old man presented himself to the emergency ward with complaints of fever, nausea, headache, muscle ache and chest pain. Two weeks before presentation he had been bitten by a pet rat. We determined that he had bacteraemia caused by a Streptobacillus moniliformis infection, which led to the development of an illness called rat bite fever. S. moniliformis is a pleomorphic gram-negative rod-shaped bacterium that is considered part of the normal nasopharyngeal flora in rats. It is the cause of two similar illnesses: rat bite fever and Haverhill fever. Clinicians should consider these infections in the work-up of unexplained fever or sepsis, certainly in the presence of known exposure to rats. Treatment consists of antibiotics.
