Project description:The study was conducted on a model of Lactiplantibacillus plantarum, one of the most studied species widely used in the food industry as a probiotic microorganism and/or microbial starter culture. As a result of step-by-step selection from the L. plantarum 8p-a3 strain isolated from the «Lactobacterin» probiotic, the L. plantarum 8p-a3-Clr-Amx strain was obtained, showing increased resistance, compared with the parent strain, to amoxicillin-clavulanic acid (MIC 20 mcg/ml) and clarithromycin (MIC 10 mcg/ml). The L. plantarum strain DMC-S1 was isolated from the intestine of Drosophila melanogaster Canton-S line. Extracellular vesicles of this bacterium can play a significant role in the drug-resistance development and host-microbe interactions.
Project description:Whole genome transcriptional profiling was used to characterize the response of Lactobacillus plantarum WCFS1 human isolate during challenge with oleuropein. Twelve independent experiments were performed and mixed at random in groups of four for total of three RNA samples. The transcriptional profile shows that Lactobacillus plantarum WCFS1 adapts its metabolic capacity to acquire certain carbohydrates and repress the expression of genes involved in fatty acid biosyntheis. The transcriptomic datasets also revealed the downregulation of genes related to the biosynthesis of capsular polysaccharides and genes coding for ABC-type transporters. In addition, induction of oligopeptide permeases is also part of the response of Lactobacillus plantarum WCFS1 to oleuropein.
Project description:In this study, we examined Caco-2 cell gene expression after infection with E. coli (Ec), Lactobacillus plantarum (Lp) and the combination of the two (mix) Keywords: Lactobacillus plantarum and E. coli influences on Caco2 cells gene expression
