Detection and analysis of iron uptake components expressed by Acinetobacter baumannii clinical isolates.

The Acinetobacter baumannii 19606 prototype strain produces a 78-kDa iron-regulated outer membrane protein immunologically related to FatA, which is required for iron acquisition by the fish pathogen Vibrio anguillarum via the anguibactin-mediated system. This A. baumannii strain also secretes histamine, a biosynthetic precursor of the siderophore anguibactin.
