Inhibición de Enterobacter cloacae por Bifidobacterium longum

Enterobacter cloacae belongs to the proteobacteria phylum (one of the most abundant in the human gut microbiota), Enterobacteriaceae family, Genus Enterobacter and species Enterobacter cloacae. This bacterium is ubiquitous, opportunistic, resistant to antibiotics and responsible for bacteremia and nosocomial infections, this fact make us search for different treatment and alternatives of control. This work proposes a control of E. cloacae growth inhibition, which is achieved by using bacterial metabolites or cell-free supernatants (also known as postbiotics) produced by Bifidobacterium longum (probiotic belonging to the Actinobacteria phylum); several works have shown that relevance growth inhibition of different pathogenic microorganisms. The B. longum postbiotic lyophilisate have shown 99% of inhibition on in vitro E. cloacae cultures. These results add to various investigations with probiotics aimed at the treatments and prevention of infections caused by E. cloacae.
