A rare case report of cysteiniphilumlitorale infection: clinical presentation and diagnostic challenges

Year: 2026

Type: article

Abstract: Cysteiniphilum litorale is a Gram-negative, non-motile, non-spore-forming bacterium. It is dependent on L-cysteine for growth. This report describes the case of a 46-year-old male who developed a severe soft-tissue infection after a sea-shrimp puncture injury to the finger, which was subsequently identified as Cysteiniphilum litorale infection. The patient's clinical course, diagnosis, and treatment are discussed, along with an emphasis on the need for early identification and appropriate management of Cysteiniphilum litorale infections.
