Rat bite fever caused by Streptobacillus notomytis mimicking pyogenic polyarthritis: A case report

Nantaporn Pirogard et al. IDCases. .

Abstract

We report the world's sixth case of rat bite fever caused by Streptobacillus notomytis that mimicked pyogenic polyarthritis and required surgical debridement in combination with prolonged antibiotic therapy. This case report highlights the higher severity of rat bite fever caused by S. notomytis compared to S. moniliformis.

Keywords: Arthritis; Rat bite fever; Streptobacillus notomytis; Zoonosis.
