Pediatr Infect Dis J. 2021 Oct 1;40(10):e381-e383. doi: 10.1097/INF.0000000000003201.

Abstract

We describe a case of septic arthritis caused by Staphylococcus pseudintermedius, a common colonizer of dogs that has emerged as a rare human pathogen. Our patient presented with ankle pain and swelling and was treated adequately with cefazolin/cephalexin and arthrotomy. S. pseudintermedius is often misidentified as other coagulase-positive staphylococcal species and has high rates of methicillin and nonpenicillin antibiotic resistance.
