Genome-wide identification of ampicillin resistance determinants in Enterococcus faecium.

Zhang Xinglin X Paganelli Fernanda L FL Bierschenk Damien D Kuipers Annemarie A Bonten Marc J M MJ Willems Rob J L RJ van Schaik Willem W

PLoS genetics 20120628 6

Enterococcus faecium has become a nosocomial pathogen of major importance, causing infections that are difficult to treat owing to its multi-drug resistance. In particular, resistance to the β-lactam antibiotic ampicillin has become ubiquitous among clinical isolates. Mutations in the low-affinity penicillin binding protein PBP5 have previously been shown to be important for ampicillin resistance in E. faecium, but the existence of additional resistance determinants has been suggested. Here, we ...[more]

AsrR regulon

Project description:Enterococcus faecium is an important opportunistic pathogen emerging in hospitals worldwide. We identified a new MarR family global regulator in E. faecium, named AsrR (antibiotic and stress response regulator). We phenotipically characterized key role for AsrR in E. faecium pathogenicity. The aim of the microarray-based experiments was to investigate the AsrR regulon in E. faecium. We constructed a mutant strain deleted for the asrR gene, we complemented the mutant and, finally, we observed genes expression in these strains in comparison with the wild-type strain. (The parental HM1070 was used to delete the asrR gene and to obtain the mutant strain. Then, the mutant strain was used to restore the asrR gene and to obtain the complemented strain.) This approach will allow us to identify the genes regulated by AsR to clarify its role in E. faecium.

Reproducibility M-Tram of Enterococcus faecium strain E1162

Project description:Two independent aliquots containing approximately 10^7 cells from the transposon mutant of E. faecium E1162 were grown at 37 C for 20 hours in 20 ml of BHI broth. Genomic DNA was isolated from the two replicate cultures and used for the generation of cDNA. The cDNA samples were labeled with Cy3 and Cy5 respectively and hybridized to a microarray that was designed using the E. faecium E1162 genome sequence.

Amino acid substitutions in ribosomal protein RpsU enable switching between high fitness and multiple-stress resistance in Listeria monocytogenes

Project description:A previously described low-fitness, high stress-resistant, variant of Listeria monocytogenes LO28 WT was subjected to an experimental evolution regime, selecting (in two parallel lines) for increased fitness in unstressed conditions. Evolved variants with increased fitness reverted to WT-like stress resistance. Whole genome sequencing and proteomics were used to identify differences between the ancestral and evolved strains.

Chicken microbiome LC - MS / MS

Project description:Bacteroidaceae are common gut microbiota members in all warm-blooded animals. However, if Bacteroidaceae are to be used as probiotics, the species selected for different hosts should reflect the natural distribution. In this study, we therefore evaluated host adaptation of bacterial species belonging to the family Bacteroidaceae. B. dorei, B. uniformis, B. xylanisolvens, B. ovatus, B. clarus, B. thetaiotaomicron and B. vulgatus represented human-adapted species while B. gallinaceum, B. caecigallinarum, B. mediterraneensis, B. caecicola, M. massiliensis, B. plebeius and B. coprocola were commonly detected in chicken but not human gut microbiota. There were 29 genes which were present in all human-adapted Bacteroides but absent from the genomes of all chicken isolates and these included genes required for the pentose cycle, and glutamate or histidine metabolism. These genes were expressed during an in vitro competitive assay, in which human-adapted Bacteroides species overgrew the chicken adapted isolates. Not a single gene specific for the chicken-adapted species was found. Instead, chicken adapted species exhibited signs of frequent horizontal gene transfer, of KUP, linA and sugE genes in particular. The differences in host adaptation should be considered when the new generation of probiotics for humans or chickens is designed.
