Recovery of an unusual Flavobacterium group IIb-like isolate from a hand infection following pig bite

Abstract

An unusual gram-negative rod (RMA 1571) was isolated from a hand infection following a pig bite. This unclassified isolate was characterized by growth requirements, microscopic examination, biochemical characteristics, antimicrobial susceptibility tests, and cellular fatty acid analysis. It was indole positive and produced yellow-pigmented growth, which placed it in the genus Flavobacterium, but its other features, including cellular fatty acid analysis, did not appear to be those of a named species.
