Title
Metagenomic analysis of the impact of nitrofurantoin treatment on the human faecal microbiota
Author
Abstract
Objectives The objective was to study changes in the faecal microbiota of patients with uncomplicated urinary tract infections (UTIs) treated with nitrofurantoin and of non-treated healthy controls using 16S rRNA analysis. Methods Serial stool samples were collected from patients receiving nitrofurantoin treatment at different timepoints [before treatment (day 1; T1), within 48 h of end of treatment (days 515; T2) and 28 days after treatment (days 3143; T3)], as well as from healthy controls. Direct DNA extraction (PowerSoil DNA Isolation Kit, MoBio Laboratories, Carlsbad, CA, USA) from stool samples was followed by pyrosequencing (454 GS FLX Titanium) of the V3V5 region of the bacterial 16S rRNA gene. Results Among UTI patients, mean proportions of the Actinobacteria phylum increased by 19.6% in the first follow-up sample (T2) in comparison with the pretreatment baseline stool sample (T1) (P = 0.026). However, proportions of Actinobacteria reversed to normal pre-antibiotic levels, with a mean difference of 1.0% compared with baseline proportions, in the second follow-up sample (T3). The increase in Actinobacteria was specifically due to an increase in the Bifidobacteriaceae family (Bifidobacterium genus), which constituted 81.0% (95% CI ±7.4%) of this phylum. Conclusions No significant impact was observed other than a temporary increase in the beneficial Bifidobacterium genus following nitrofurantoin treatment, which supports its reintroduction into clinical use.
