Abstract
Background: Acinetobacter pittii, is typically a nosocomial pathogen and is rarely community-acquired.
Case presentation: A 50-year-old male in China developed septic shock, multiorgan failure, and severe pneumonia. Cultures confirmed A. pittii, resistant to piperacillin-tazobactam but susceptible to other antibiotics. He recovered after 43 days of treatment.
Conclusions: Genome sequencing revealed high virulence, confirmed by larvicidal assays. This first report of community-acquired A. pittii highlights its potential for severe infections and septic shock, necessitating clinician awareness.
