Project description:The first case reports involving Propionimicrobium lymphophilum, a rarely encountered anaerobic Gram-positive non-spore-forming rod, are presented here as urinary tract infections. Initial detection of these bacteria required urine Gram stains. Comparison of the type strain to the two isolates by various methods is depicted and includes antimicrobial susceptibility data.
Project description:Propionimicrobium lymphophilum is an anaerobic Gram-positive bacillus that exists in human skin and urinary tract. The pathogenicity is, however, not well known. Only two cases of urinary tract infection have been described recently. In the case presented here, the bacterium was isolated, concomitant with Actinotignum schaalii, from blood culture of a patient with fever and difficulty of urination. The bacteria were identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and 16S rRNA sequencing. The case was successfully treated with ampicillin/sulbactam.
Project description:BackgroundDespite a unique microbiome in urine, the relationship between nocturnal enuresis and the urobiome remains unclear. This study aimed to compare the presence of specific bacterial species in the urine of children with and without nocturnal enuresis.MethodsWe used 16S ribosomal RNA gene sequencing to analyze the urobiome in urine samples obtained from the two groups of children. The presence of Propionimicrobium lymphophilum was examined using real-time PCR in the urine of 25 children diagnosed with monosymptomatic nocturnal enuresis (MNE), and 17 children without this condition.ResultsChildren with MNE exhibited a significantly higher prevalence of P. lymphophilum: 16 out of 25 (64.0%) compared to 4 out of 17 (23.5%) in the control group. Among children with frequent bedwetting, there was a significantly higher prevalence of P. lymphophilum;15 out of 16 (93.8%) compared to 2 out of 9 (22.2%) in those with infrequent bedwetting. Bacterial culture tests confirmed the anaerobic growth of P. lymphophilum isolates from urine samples of two PCR-positive patients with MNE. These isolates were found to be susceptible to ampicillin.ConclusionThese findings suggest that P. lymphophilum may be associated with chronic urinary tract infections and potentially contribute to the development of MNE in children.
Project description:Investigation of whole genome gene expression level changes in Lactococcus lactis KCTC 3769T,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 . This proves that transcriptional profiling can facilitate in elucidating the genetic distance between closely related strains.

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:Comparison of gene expression between L. reuteri DSM 17938 and L. reuteri DSM 17938::pocR mutant grown in semi-defined medium after 24h of growth at 37C in anaerobic condition. PocR is an AraC-like transcriptional regulator, and changes in gene expression between mutant and wild-type strains would indicate genes involved in the PocR regulon.
