چکیده

Widespread multidrug resistance in Escherichia coli has necessitated the reintroduction of older antibiotics, such as nitrofurantoin. However, mechanisms by which resistance to nitrofurantoin emerges in E. coli are not well elucidated. Toward this aim, we sequenced two nitrofurantoin-sensitive E. coli sequence types (ST540 and ST2747) and their four nitrofurantoin-resistant derivatives generated in vitro under aerobic and anaerobic growth conditions.

An in vitro deletion in ribE encoding lumazine synthase contributes to nitrofurantoin resistance in Escherichia coli.

Nitrofurantoin has been used for decades for the treatment of urinary tract infections (UTIs), but clinically significant resistance in Escherichia coli is uncommon. Nitrofurantoin concentrations in the gastrointestinal tract tend to be low, which might facilitate selection of nitrofurantoin-resistant (NIT-R) strains in the gut flora. We subjected two nitrofurantoin-susceptible intestinal E. co...

Detection of TEM, SHV and CTX-M Antibiotic Resistance Genes in Escherichia coli Isolates from Infected Wounds

ABSTRACT        Background and Objective: Escherichia coli is one of the most common causes of hospital-acquired infections. Extended-spectrum β-lactamase (ESBL)-producing E. coli strains are resistant to third-generation cephalosporins. The three main genes involved in ESBL production are TEM, SHV and CTX-M. Detection of ESBL-producing E. coli is of importan...
