Abstract

Introduction: Staphylococcus intermedius group (SIG), a known veterinary pathogen with the potential for zoonotic human infections, comprises S. intermedius, S. pseudointermedius and S. delphini, which are not easily distinguishable. Without the proper equipment and procedures, it can also be mistaken with Staphylococcus aureus (SAu), leading to the misknowledge of its true incidence.

Case: A 52-year-old male with diabetes presented with fever and malaise. He developed respiratory failure and altered mental status, requiring intensive care. Blood cultures and bronchoalveolar lavage culture developed methicillin-resistant SIG. Despite rapid adjustment of empiric antibiotic therapy, he died in multiple organ failure.

Conclusions: Incorporating knowledge about this new pathogen and its aggressiveness to daily clinical practice could, through a high index of suspicion and detailed anamnesis, reduce misdiagnoses.
