This proves that transcriptional profiling can facilitate in elucidating the genetic distance between closely related strains. A one chip study using total RNA recovered from of L. raffinolactis DSM 20443T, L. plantarum DSM 20686T, L. fujiensis JSM 16395T, L. garvieae KCTC 3772T, L. piscium DSM 6634T and L. chungangensis CAU 28T . For the the transcriptome of of L. raffinolactis DSM 20443T, L. plantarum DSM 20686T, L. fujiensis JSM 16395T, L. garvieae KCTC 3772T, L. piscium DSM 6634T and L. chungangensis CAU 28T was analyzed using the Lactococcus lactis KCTC 3769T microarray platform
Project description:Enterococcus faecalis, a member of the human gastrointestinal microbiota, is a Gram-positive, opportunistic pathogen associated with hospital-acquired wound, bloodstream, and urinary tract infections. E. faecalis can suppress or evade immune-mediated clearance by macrophages to promote persistent infection, although the exact mechanisms and bacterial factor(s) involved are not well-defined. In this study, we examined E. faecalis factor(s) involved in suppressing macrophage activation, as well the macrophage pathways modulated by E. faecalis to suppress activation. We observed that E. faecalis prevents ERK and p65 phosphorylation and reduces MyD88 expression leading to a reduction in NF-κB activity. We identified E. faecalis lactate dehydrogenase, which is important for lactic acid production by E. faecalis, to be necessary for macrophage suppression and demonstrated that E. faecalis lactate dehydrogenase-mediated immune suppression promotes E. coli survival during polymicrobial wound infection. Taken together, these results suggest that that E. faecalis-derived lactic acid is involved in macrophage subversion and may help to promote the virulence of co-infecting bacteria.
