Enhancement of antibiotic activity by efflux inhibitors against multidrug resistant Mycobacterium tuberculosis clinical isolates from Brazil

Abstract: Drug resistant tuberculosis continues to increase and new approaches for its treatment are necessary. The identification of M. tuberculosis clinical isolates presenting efflux as part of their resistant phenotype has a major impact in tuberculosis treatment. In this work, we used a checkerboard procedure combined with the tetrazolium microplate-based assay (TEMA) to study single combinations between antituberculosis drugs and efflux inhibitors (EIs) against multidrug resistant M. tuberculosis clinical isolates… Show more

“…According to previous reports, the combination of an antibiotic and an efflux inhibitor at subminimal inhibitory concentrations delays the growth of M. tuberculosis drug-resistant strains (Coelho et al, 2015; Machado et al, 2017). Therefore, in R. anatipestifer drug-resistant strains, the EP is also believed to contribute to the overall level of antibiotic resistance described above.…”

“…Z. et al, 2016, chapter 28). The effects of some EPIs on antimicrobial susceptibilities have been studied in several microorganisms, including Escherichia coli (Opperman et al, 2014), Salmonella (Sutkuviene et al, 2013), Klebsiella pneumoniae (Chevalier et al, 2004), Mycobacterium tuberculosis (Coelho et al, 2015; Machado et al, 2017), Acinetobacter baumannii (Richmond et al, 2013), and Campylobacter (Kurincic et al, 2012). However, in regard to this, no systematic, comprehensive research has been conducted in R. anatipestifer .…”

“…The synergistic activity between the efflux inhibitors, antibiotics and EtBr was evaluated by checkerboard assays as previously described (Pillai, Moellering & Eliopoulos, 2005; Coelho et al, 2015). Two-fold serial dilutions of the compounds were made to achieve the following concentrations: 320 µM–40 µM.…”
