A case of sepsis due to a rare carbapenem-resistant Ignatzschineria species

Abstract

Ignatzschineria species have emerged only recently and few cases have been identified worldwide. It has been determined that maggots likely serve as the vector of transmission and the majority of cases described involved cutaneous myiasis. This article presents the first case of an Ignatzschineria species closely related to I. larvae/I. ureclastica causing bacteremia in North America. This isolated Ignatzschineria species is also unique in its broad antimicrobial resistance pattern to carbapenem antimicrobials, an uncommon finding among global Ignatzschineria isolates. Improving the ability to identify Ignatzschineria species is an important step to develop the necessary CLSI breakpoints and treatment guidelines. The paucity of information regarding Ignatzschineria species and the inability to accurately identify these organisms indicate the need for more research and improved identification techniques of this emerging pathogen.

Effect of thermal treatment of illite on the bioavailability of copper and zinc in the aerobic composting of pig manure with corn straw

“…These results indicated that the addition of illite in the composting process effectively inhibited the growth and survival of Streptococcus (with low relative abundance <0.01%) in the mature compost. These results were consistent with those previously reported ( Coelho et al, 2022 ; Maniam and Argentine, 2022 ). Fermentimonas was revealed with the highest relative abundance at the end of the composting process, which was probably associated with the degradation of glucose and fructose and involved in heavy metal passivation, showing the highest relative abundance at the end of composting of group I-5.…”

Ignatzschineria larvae Bacteremia in a Patient With Chronic Leg Ulcer: A Case Report and Review of the Literature

“…There are three genera of Ignatzschineria: larvae , indica , and ureiclastica . All three genera are non-sporulating, non-haemolytic, non-motile, rod-shaped bacteria that were first isolated in 2001 from larvae of Wohlfahrtia magnifica, a parasitic flesh fly causing myiasis in several animal species and occasionally in humans [ 4 ]. Originally the name of this bacterium was simply Schineria in honour of Ignatz Rudolph Schiner (1813-1873), who first described the fly Wohlfahrtia magnifica in 1862 [ 3 ].…”
