Protective Effect of Lipoteichoic Acid from Lactobacillus casei and Lactobacillus fermentum against Pseudomonas aeruginosa in Mice

Abstract
Lipoteichoic acid (LTA) from Lactobacillus casei YIT 9018 or Lactobacillus fermentum YIT 0159 augmented the resistance of C57BL/6 mice to infection with Pseudomonas aeruginosa, but conferred no resistance to Listeria monocytogenes. It is suggested that LTA was unable to activate macrophages.
