[DF-2, a "new" gram-negative bacterium]

Abstract

Dysgonic fermenter 2 (DF-2) is a long, fastidious gram negative rod that leads to life-threatening infections in immunocompromised and especially splenectomized patients. It can also severely affect the healthy individual. It is mainly acquired through contact with dogs and after dog bites. The infection has rarely been described, due to difficulties in isolating DF-2, its relatively low virulence, its susceptibility to antimicrobial agents and the frequent administration of antibiotics after animal bites. A systematic approach to the practical management of dog bite wounds is proposed.
