The findings published on Nature Microbiology, revealed that the presence of the low abundant bacterium, member of the microbiota, Klebsiella michiganensis was sufficient to explain the resistance to invasion by other bacteria like E. coli or Salmonella because it can metabolize nutrients available in the intestine more efficiently, competing against potential invaders and preventing the entry of other bacteria that can harm the host.

The increasing consumption of antibiotics is a public health problem that can compromise the effectiveness of future treatments, highlighting the importance of the identification of bacteria and mechanisms that can minimize the negative effects associated with their consumption.
