Transcriptional analysis between Streptomyces clavuligerus ATCC 27064 and a mutant altered in antibiotic production

ABSTRACT: The objective was to analyze the differential expression between the wild strain and the Streptomyces clavuligerus ΔclaR::aac mutant Six experimental conditions were assayed, two strains (Streptomyces clavuligerus ATCC 27064, S. clavuligerus ΔclaR::aac) in three culture times (22.5h, 46.5h and 60 h). Two biological replicates for each condition.

Streptomyces clavuligerus claR::aph is a claR-defective mutant, but in addition to its claR defect it also carries fewer copies of the resident linear plasmids pSCL2 and pSCL4 (on the order of 4 × 10(5)-fold lower than the wild-type strain), as shown by qPCR. To determine the function of ClaR without potential interference due to plasmid copy number, a new strain, S. clavuligerus ΔclaR::aac, with claR deleted and carrying the wild-type level of plasmids, was constructed. Transcriptomic analyses ...[more]

Switching on antibiotic resistance in Staphylococcus aureus M-bM-^@M-^S Contribution of WalK and VraS histidine kinases in the development of vancomycin and daptomycin resistance

Project description:Staphylococcus aureus is a notorious bacterial pathogen that causes a broad range of human diseases, and isolates that are resistant to several antibiotic classes including last resort antibiotics like vancomycin and daptomycin complicate the situation. We characterized S. aureus VC40, a strain that shows full resistance to vancomycin (MIC of 64 M-BM-5g/ml) and daptomycin (MIC of 4 M-BM-5g/ml) as well as a decreased susceptibility to further cell wall active agents. Genome sequencing revealed mutations in genes encoding the histidine kinases WalK and VraS that control cell envelope related processes and gene expression profiling indicated the induction of the respective regulons in strain VC40. Reconstitution of the mutations in walK or vraS into the susceptible S. aureus NCTC 8325 background resulted in a considerably increased resistance to vancomycin and daptomycin with MICs surpassing the clinical breakpoints for these antibiotics, thereby generating vancomycin-intermediate S. aureus (VISA) strains. As observed for S. aureus VC40, the walKwalk and vraS mutations also led to an increased expression of the respective regulons in the NCTC 8325 background. Phenotypic studies showed that S. aureus VC40 as well as the walKwalk and vraS mutants of strain NCTC 8325 were characterized by a significantly thickened cell wall, a decreased growth rate, a reduced autolytic activity and an increased resistance to lysostaphin-induced lysis. These results demonstrate that the WalK and VraS histidine kinases act as major switches which allow S. aureus to rapidly develop vancomycin resistance up to the VISA level via mutation of one single gene locus and concomitantly contribute to cross-resistance to other antibiotics including the last resort antibiotic daptomycin. Microarray was used to evaluate alteration in the transcriptome of mutS mutant and compared to the parental strain VC40

A comprehensive microarray analysis of Enterococcus faecium in response to vancomycin in combination with the essential oil components carvacrol and cuminaldehyde

Project description:This study aims to determine the global gene expression in vancomycin resistant Enterococcus faecium (VRE) in response to a novel essential oil-vancomycin combination, and the individual components (vancomycin, carvacrol and cuminaldehyde) to help determine the mechanism of action of this antimicrobial formulation. This formulation increases the susceptibility of VRE to vancomycin and the array provides data on the synergistic mechanism of action. Five conditions (1. Control; 2. Carvacrol, 1.98 mM; 3. Cuminaldehyde, 4.20 mM; 4. Vancomycin, 0.031 mg/l; 5. Combination, 1.98 mM Carvacrol, 4.2 mM Cuminaldehyde, 0.031 mg/l vancomycin) all with 1% DMSO were tested in triplicate with a 60 minute exposure time before extraction.

Transcriptome data for Streptomyces coelicolor at 2 growth stage

Project description:Transcriptome analysis of Streptomyces coelicolor MT1110 cultures grown in SMM + 0.5% casaminoacids at 30?C up to mid exponential and stationary phase. Total RNA was extracted from both stages of growth, labelled with Cy3-dCTP and mixed with genomic DNA from S. coelicolor M145 labelled with Cy5-dCTP that was used as common reference in an indirect type of microarray experiment. Labelled Cy3/Cy5-dCTP samples were hybridized onto SCO-Chip2-v2 High Density IJISS arrays.
