Antagonistic Activity of Lactic Acid Bacteria Lactobacillus spp. against Clinical Isolates of Klebsiella pneumoniae

Antagonistic Activity of Lactic Acid Bacteria Lactobacillus spp. against Clinical Isolates of... The screening of three strains of lactic acid bacteria identified as Lactobacillus rhamnosus, Lactobacillus reuteri, and Lactobacillus helveticus showed significant antagonistic activity against Klebsiella pneumoniae strains characterized by multiple antibiotic resistance. Lactobacilli cocultivated with the Klebsiella strains inhibited their growth 20 to 86% on the first and second days, respectively. Exoproteome analysis of L. rhamnosus cocultivated with K. pneumoniae revealed the induction of peptidoglycan hydrolases, including extracellular lytic transglycosylases, family II (MltA), and endopeptidases capable of disrupting the peptidoglycan bacterial cell wall. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Applied Biochemistry and Microbiology Springer Journals

Abstract

The screening of three strains of lactic acid bacteria identified as Lactobacillus rhamnosus, Lactobacillus reuteri, and Lactobacillus helveticus showed significant antagonistic activity against Klebsiella pneumoniae strains characterized by multiple antibiotic resistance. Lactobacilli cocultivated with the Klebsiella strains inhibited their growth 20 to 86% on the first and second days, respectively. Exoproteome analysis of L. rhamnosus cocultivated with K. pneumoniae revealed the induction of peptidoglycan hydrolases, including extracellular lytic transglycosylases, family II (MltA), and endopeptidases capable of disrupting the peptidoglycan bacterial cell wall.
