Abstract
RATIONALE: Granulicatella adiacens (G adiacens) are colonizing bacteria commonly found in the mouth, intestine, and urogenital tract. These bacteria tend to cause infectious diseases in immunocompromised hosts, such as artificial joint infections, osteomyelitis, meningitis, peritonitis, and lung abscess. PATIENT CONCERNS AND DIAGNOSES: An unusual case involved a 37-year-old female who developed an abdominal wall infection adjacent to G adiacens due to incorrect insulin injection behavior. INTERVENTIONS: The patient received targeted anti-infection treatment, including wound dressing changes and blood glucose management. OUTCOMES: Her symptoms, which included fever and a skin rupture with pus and bleeding on the left lower abdomen, improved markedly. She was discharged after 14 days of hospitalization, and her abdominal wound fully healed 5 months later. LESSONS: This case underscores the importance of prompt identification and careful wound care. The nurse practitioner played a critical role in specimen collection, wound management, antibiotic administration, and patient education. Integrated care and interdisciplinary collaboration were key factors that led to the patient's significant improvement and successful discharge.
