Introduction: Trueperella bernardiae is a gram-negative coccobacilli that was initially categorized as coryneform bacteria, and thus frequently, it was not further investigated as a pathogenic organism. Matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF) has revolutionized the identification of bacteria, including T. bernardiae. Now case reports for T. bernardiae infections are starting to be reported, but it remains a rare pathogen for infections. Case Presentation: Here we are reporting a rare case of T. bernardiae bacteremia, presenting with sepsis and imaging finding showing pelvic septic arthritis, micro-abscesses, and osteomyelitis. It would have likely started as urinary tract infection, followed by osteomyelitis and bacteremia. The patient was managed with intravenous vancomycin. The follow-up clinic visit showed clinical improvement. This article also provides a brief literature review of T. bernardiae infections. Conclusion: T. bernardiae infections are rare but have clinical significance. This case adds another case to the literature regarding T. bernardiae infections and especially highlights the point that they can present with a more serious presentation like sepsis. MALDI-TOF helps in the identification of these rare pathogens.
