Phenotypic convergent evolution towards fosfomycin collateral sensitivity of Pseudomonas aeruginosa antibiotic resistant mutants

ABSTRACT: In this work we describe a robust fosfomycin collateral sensitivity phenotype of Pseudomonas aeruginosa resistant mutants selected by antibiotics from different structural families. The underlying mechanism was the reduced expression of the genes encoding the peptidoglycan-recycling pathway, which preserves the peptidoglycan synthesis in situations where the de novo synthesis is blocked, and of fosA, encoding a fosfomycin-inactivating enzyme.

Staphylococcus aureus treated with fosfomycin

Project description:Staphylococcus aureus is a highly adaptable human pathogen; therefore a constant search for new effective antibiotic compounds is being preformed. Gene expression profiling can be used to determine potential targets and mechanisms of action (MOA) of known or potential drugs. The goal of our study was a development of a focused transcriptome platform to be used for confirming the MOA of new chemical entities which are designed as inhibitors of Mur ligases. A model transcriptional profile was set up for well described inhibitor of MurA ligase, fosfomycin. Moreover, we wanted to identify the pathways and processes primarily affected by this compound. S. aureus ATCC 29213 cells were treated with low concentrations of fosfomycin (1 and 4 Âµg/ml, respectively) and harvested at 10, 20 and 40 minutes after treatment, respectively. RNA was isolated, transcribed, labeled and hybridized to S. aureus GeneChips, representing approximately 3000 S. aureus genes. Using meta-analysis of our results and the results in the S. aureus microarray database, we have confirmed that fosfomycin induces âcell wall stimulonâ genes and were able to identify genes and pathways specifically modulated by fosfomycin. Time course, different fosfomycin concentration

Fosfomycin uptake in Escherichia coli is mediated by the outer membrane porins OmpF, OmpC and LamB

Project description:The antibiotic fosfomycin is widely recognized for treatment of lower urinary tract infections caused by Escherichia coli and lately gained importance as a therapeutic option to combat multidrug resistant bacteria. Still, resistance to fosfomycin frequently develops through mutations reducing its uptake. Whereas the inner membrane transport of fosfomycin has been extensively studied in E. coli, its outer membrane (OM) transport remains insufficiently understood. While evaluating minimal inhibitory concentrations in OM porin-deficient mutants, we observed that the E. coli ΔompCΔompF strain is five times more resistant to fosfomycin than the wild type and the respective single mutants. Continuous monitoring of cell lysis of porin-deficient strains in response to fosfomycin additionally indicated the relevance of LamB. Furthermore, the physiological relevance of OmpF, OmpC and LamB for fosfomycin uptake was confirmed by electrophysiological and transcriptional analysis. This study expands the knowledge of how fosfomycin crosses the OM of E. coli.

Convergent phenotypic evolution towards fosfomycin collateral sensitivity of Pseudomonas aeruginosa antibiotic-resistant mutants.

Project description:The rise of antibiotic resistance and the reduced amount of novel antibiotics support the need of developing novel strategies to fight infections, based on improving the use of the antibiotics we already have. Collateral sensitivity is an evolutionary trade-off associated with the acquisition of antibiotic resistance that can be exploited to tackle this relevant health problem. However, different works have shown that patterns of collateral sensitivity are not always conserved, thus precluding the exploitation of this evolutionary trade-off to fight infections. In this work, we identify a robust pattern of collateral sensitivity to fosfomycin in Pseudomonas aeruginosa antibiotic-resistant mutants, selected by antibiotics belonging to different structural families. We characterize the underlying mechanism of the collateral sensitivity observed, which is a reduced expression of the genes encoding the peptidoglycan-recycling pathway, which preserves the peptidoglycan synthesis in situations where its de novo synthesis is blocked, and a reduced expression of fosA, encoding a fosfomycin-inactivating enzyme. We propose that the identification of robust collateral sensitivity patterns, as well as the understanding of the molecular mechanisms behind these phenotypes, would provide valuable information to design evolution-based strategies to treat bacterial infections.

Role of redox-dependent, flow-related regulation of AT1R expression in collateral growth impairment

Project description:Genomic analysis of control and collateral arteries was used to investigate mechanisms responsible for impaired collateral growth in the Spontaneously Hypertensive rat, an animal model of essential hypertension with increased oxidative and nitrosative stress and metabolic abnormalities. A fundamental difference was observed in the overall expression pattern in SHR vs WKY collaterals. Redox related genes with altered expression included cyba (the gene encoding p22phox), superoxide dismutase 3, and thioredoxin reductases 1 and 2. Cystatin C, hevin, angiotensinogen, and the angiotensin type 1b receptor (AT1bR) had altered collateral expression that was confirmed by RT-PCR. These molecules are known to have significant roles in other types of arterial remodeling. Of specific interest was the AT1bR which exhibited up-regulation in WKY collaterals, but down-regulation in SHR. A remarkable increase in AT1R protein was observed in WKY but not SHR collaterals. Pharmacological blockade of the AT1R with losartan prevented collateral luminal expansion in WKY. In SHR, captopril restored redox status assessed by cyba expression and nitric oxide concentration, prevented collateral AT1bR down-regulation and re-established the capacity for collateral growth. These results indicate that redox-status significantly alters flow-mediated transcriptional regulation and demonstrate that increased flow-related expression/activation of the AT1R is required for normal collateral luminal expansion but is altered by chronic oxidative and/or nitrosative stress in hypertensive rats.

Effects of fosfomycin on biofilm of a clinical Staphylococcus aureus isolated from osteoarticular infection by transcriptomal approach

Project description:The aim of the present study was to investigate the mechanisms by which fosfomycin restrains biofilm formation and affects a 24h-old biofilm of S. aureus. RNA sequencing (RNA-Seq) technology was used to compare the transcriptomes of S. aureus biofilms formed or treated with sublethal concentrations of fosfomycin.

The inactivation of enzymes belonging to the central carbon metabolism, a novel mechanism of developing antibiotic resistance

Project description:Fosfomycin is a bactericidal antibiotic, analogous to phosphoenolpyruvate (PEP) that exerts its activity by inhibiting the activity of MurA. This enzyme catalyzes the first step of peptidoglycan biosynthesis, the transfer of enolpyruvate from PEP to uridine- diphosphate-N-acetylglucosamine. Fosfomycin is increasingly used in the last years, mainly for treating infections caused by Gram-negative multidrug resistant bacteria as Stenotrophomonas maltophilia, an opportunistic pathogen characterized by its low susceptibility to antibiotics of common use. The mechanisms of mutational resistance to fosfomycin in Stenotrophomonas maltophilia were studied in the current work. None of the mechanisms so far described for other organisms, which include the production of fosfomycin inactivating enzymes, target modification, induction of alternative peptidoglycan biosynthesis pathway and the impaired entrance of the antibiotic, are involved in the acquisition of such resistance by this bacterial species. Rather the unique cause of resistance in the studied mutants is the mutational inactivation of different enzymes belonging to the Embden-Meyerhof-Parnas central metabolism pathway. The amount of intracellular fosfomycin accumulation did not change in any of these mutants showing that neither the inactivation nor the transport of the antibiotic were involved. Transcriptomic analysis also showed that the mutants did not present changes in the expression level of putative alternative peptidoglycan biosynthesis pathway genes neither any related enzyme. Finally, the mutants did not present an increased PEP concentration that might compete with fosfomycin for its binding to MurA. Based on these results, we describe a completely novel mechanism of antibiotic resistance based on the remodeling of S. maltophilia metabolism.
