Abstract:
A 58-year-old man with history of mitral valve prolapse and previous motor vehicle accident presented with one
week history of lower back pain and fever. He was initially treated for pyelonephritis and given ceftriaxone. Blood
culture grew Granulicatella adiacens after 7 days of incubation. The laboratory then referred the case to infectious
disease team in view of possible infective endocarditis. Urgent echocardiogram was done and confirmed the diagnosis. His antibiotic was changed to intravenous benzylpenicillin and gentamicin. Granulicatella adiacens are difficult
to be isolated in the laboratory hence they imposed certain challenges in laboratory identification. Most patients with
Granulicatella adiacens infective endocarditis present with non-specific symptoms, imposing further challenge in
recognizing the condition. These factors posed significant challenges in diagnosing Granulicatella adiacens endocarditis. This case highlighted challenges faced by the laboratories and the need of high index of clinical suspicion
and prompt communication to ensure optimum patient care and management.
