Resistant Disease Escherichia coli infection [ICD-11: 1A03.0]
Experimental Note Discovered Using In-vivo Testing Model
In Vitro Model THP1 cells Pleural effusion Homo sapiens (Human) CVCL_0006
Mechanism Description The oxygen-insensitive major and minor (nsfA and nfsB, respectively) flavoprotein nitroreductases of E. coli, were shown to reduce nitrofurans and later, metronidazole. These nitroreductases share a similar structure to the nim genes described below. Mutants of both nfsA/nfsB in E. coli show reduced susceptibility to metronidazole. A 2-nitroimidazole nitrohydrolase (NnhA) was also shown to render E. coli resistant to 2-nitroimidazoles.

Resistant Disease Escherichia coli infection [ICD-11: 1A03.0]
Experimental Note Discovered Using In-vivo Testing Model
In Vitro Model THP1 cells Pleural effusion Homo sapiens (Human) CVCL_0006
Mechanism Description In B. fragilis, nimA encodes a 5-nitroimidazole reductase reducing the metronidazole analogue dimetronidazole (1,2-dimethyl-5-nitroimidazole) to the amino derivative, preventing ring fission and associated toxicity. The role of nim genes in metronidazole resistance is controversial. It has been established that overexpression of a NimA homologue from B. fragilis induces a 3-fold increase in metronidazole resistance in E. coli.

Mechanism Description E. coli mutants lacking the ability to reduce nitrate and chlorate, presumably reducing the rate of metronidazole uptake, are also resistant. A reduced growth rate is also associated with metronidazole resistance in C. perfringens, C. difficile and B. fragilis. Bacteroides resistance-nodulation-division (RND) efflux pumps (bme) also reduce susceptibility to metronidazole.
