Ignatzschineria species Bacteremia: A Case Report and Review of the Literature

Abstract

Ignatzschineria species, a member of the Gammaproteobacteria class of bacteria, is a gram-negative, aerobic, non-spore forming rod. This emerging human pathogen has been found in the digestive tract of the parasitic Wohlfarhtia magnifica fly. Infections in humans are uncommon and are usually associated with maggot infestation (wound myiasis). Rare cases of Ignatzschineria species bacteremia have been reported in individuals with myiasis of chronic skin wounds. Current literature describes 4 known species of Ignatzschineria: I. indica, I. larvae, I. ureiclastica, and I. cameli. An additional 2 cases of Ignatzachineria bacteremia were caused by Ignatzschineria species that were “unable to be identified;” they appeared to be closely related to I. larvae and I. ureclastica culture type. This case discusses Ignatzschineria bacteremia in a 66-year-old undomiciled male from the United States with myiasis of a chronic leg ulcer and reviews the literature on Ignatzschineria bacteremia
