Interests: decreasing the intestinal carriage of multidrug resistant bacteria with prebiotic and new probiotics

Special Issue Information

Dear Colleagues,

The intestinal microbiota is a major reservoir of multidrug-resistant bacteria (MDRB). Intestinal colonization by MDRB is promoted by intestinal dysbiosis and may evolve from an asymptomatic carriage to various infections including urinary, gastrointestinal and bloodstream infections. Furthermore, the intestinal carriage of MDRB can lead to environmental contamination and transmission to healthy or diseased subjects. Hence, treatments to decrease this carriage are crucial in order to limit the global spread of antimicrobial resistance. Various strategies have been assessed, but none has proved to be effective so far.

The aim of this Issue is to explore new approaches able to fight such a carriage of MDRB, particularly carbapenem and ESBL-producing Escherichia coli, Klebsiella pneumoniae, and Enterobacter cloacae, but also vancomycin-resistant enterococci and other relevant species. A diversity of strategies will be welcome: for example, the use of prebiotics, of probiotics (in particular new probiotics), the development of new quorum-sensing inhibitors, the synthesis of new prodrugs to specifically target MDRB, the use of bacteriophages, fecal transplantation, the beneficial effect of some diets, etc. Articles on the better use of antibiotics will also be considered, particularly those on the methodologies able to prevent intestinal dysbiosis.

Probiotics have been shown to possess anti-inflammatory effects in the gut by directly reducing the production of pro-inflammatory cytokines and by secreting anti-inflammatory molecules. However, their systemic anti-inflammatory effects have not been thoroughly investigated. In this study, we aimed to develop probiotics that have efficacy in both intestinal and lung inflammation. Lactobacillus plantarum KC3 (KC3), which was isolated from kimchi, was selected as a pre-candidate based on its inhibitory effects on the production of pro-inflammatory cytokines in vitro. To further validate the effectiveness of KC3, we used ear edema, DSS-induced colitis, and ambient particulate-matter-induced lung inflammation models. First, KC3 exhibited direct anti-inflammatory effects on intestinal cells with the inhibition of IL-1β and TNF-α production. Additionally, KC3 treatment alleviated ear edema and DSS-induced colic inflammation, improving colon length and increasing the number of regulatory T cells. Beyond its local intestinal anti-inflammatory activity, KC3 inhibited pro-inflammatory cytokines in the bronchoalveolar fluid and prevented neutrophil infiltration in the lungs. These results suggest that KC3 could be a potential functional ingredient with respiratory protective effects against air-pollutant-derived inflammation, as well as for the treatment of local gut disorders.
