Ignatzschineria larvae Bacteremia Following Lucilia sp. Myiasis in an Irregular Migrant: A Case Report

Abstract

Bacteremia induced by wound myiasis is uncommon and therefore rarely suspected by clinicians when treating patients with neglected wounds. We present a case of <i>Ignatzschineria larvae</i> bacteremia as a complication of <i>Lucilia</i> sp. maggot wound myiasis in a young male migrant. This is the first reported human case of <i>Ignatzschineria</i> bacteremia in Slovenia and one of the 2 described in the literature where the fly larvae infesting the wounds of the patient with <i>Ignatzschineria</i> bacteremia were not only suspected to be <i>Lucilia</i> sp. but also entomologically identified.

“…transmitted by flies are more commonly associated with human wound myiasis. Bacteria carried by maggots can spread into the bloodstream of the infested host, causing systemic infections as documented in previous case reports (Nadrah et al, 2021;Gupta et al, 2011;Snyder et a., 2020). There is a well-documented relation betweenIgnatzschineria spp.…”

“…Similar to the previous reports, our clinical isolate Ignatzschineria spp. was found to be Gram-negative, nonsporulating, non-haemolytic, nonmotile, rod-shaped bacteria (Nadrah et al, 2021;DiFranza et al, 2021). Although,Ignatzschineria spp.…”

“…Such invasions may result in mild to severe illness or even death. Flies of several families are obligatory parasites on domestic animals, the most important family causing wound myiasis isCalliphoridae and included genera of flies are Calliphora, Lucilia, Chrysomyia and Cochliomyia (Nadrah et al, 2021) but flies belonging to family Calliphoridae and Sarcophagidaemostly cause traumatic wound and subsequent myiasis (Roy and Dasgupta, 1982) which is one of the commonest and widespread clinical problems in veterinary practice in India (Chhabra & Pathak, 2009). Exposed lesions attract and stimulate females to oviposit (Francesconi & Lupi, 2012).…”
