Introduction
Trueperella bernardiae (T.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. Bernadiae 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.
