Reactive arthritis linked to Abiotrophia defectiva: expanding the spectrum of post-infectious arthritis

Reactive arthritis is a form of sterile inflammatory oligoarthritis that occurs days to weeks following a genitourinary or gastrointestinal infection presenting with joint pain and swelling. Extra-articular manifestations include uveitis, oral ulcers, urethritis, and skin rashes. It is commonly due to gram negative bacteria such as Chlamdyia, Campylobacter, Salmonella, Shigella, and Yersinia. Recently, rare pathogens such as Streptococci, Clostridium difficile, Escherichia coli, Mycoplasma pneumoniae have also been implicated. However, Abiotrophia defectiva, a gram-positive bacterium, is not listed among them. We present to the best of our knowledge the only case of Abiotrophia defectiva as a causative agent of reactive arthritis.
