Why the study?
Abiotrophia defectiva is a rare cause of infective endocarditis typically presenting with florid sepsis, but clinical recognition may be difficult when presenting non-specifically in older frail patients.
Highlights that Abiotrophia defectiva infective endocarditis can present atypically without classical clinical findings in older frail patients.
Clinicians should consider atypical pathogens in culture-negative IE among frail elderly; single case report leaves broader epidemiology open.
Abiotrophia defectiva (A defectiva) , a rare cause of bacterial infective endocarditis(IE) often presents with pyrexia and florid sepsis. This case highlights that A defectiva IE can present non-specifically in older frail patients without classical clinical findings. A. defectiva may be associated with a high proportion of culture-negative IE.
