Onchycobacter anthropi Pyomyositis in Immunocompetent Patient: Case Report

INTRODUCTION: Ochrobactrum anthropi is an unusual low virulence emerging pathogen that rarely causes orthopedic infection and its clinical picture is not well described. It usually causes infection in immunocompromised hosts with indwelling catheters or foreign bodies, such as the central venous catheters. CASE REPORT: We reported a case of O. anthropi pyomyositis in a 22-year-old immunocompetent male patient not on any invasive procedure presented with raised temperature, left shoulder pain, and restriction of movements. Diagnosis was confirmed with the help of MRI and biopsy. He was successfully managed with surgical debridement and appropriate antibiotics. CONCLUSION: Our case highlights the ability of O. anthropi to cause pyomyositis in immunocompetent individuals and its relevance in the field of orthopaedic infection.
