Systems-level analysis of NalD mutation, a recurrent driver of rapid drug resistance in acute Pseudomonas aeruginosa infection
2019
PLoS Computational Biology
Preserved Fulltext
Pseudomonas aeruginosa, a main cause of human infection, can gain resistance to the antibiotic aztreonam through a mutation in NalD, a transcriptional repressor of cellular efflux. ...
A detailed analysis of one patient's timeline shows how this mutation can emerge in vivo and drive rapid evolution of resistance while the patient received cancer treatment, a bone marrow transplantation ...
NalD variation linked to multi-drug resistance Our data suggests that NalD is a recurrent driver for aztreonam resistance in P. aeruginosa acute infection. ...

SUMMARY In recent years, the worldwide spread of the so-called high-risk clones of multidrug-resistant or extensively drug-resistant (MDR/XDR) Pseudomonas aeruginosa has become a public health threat. ...
A section is devoted to reviewing upcoming active drugs such as imipenem-relebactam, cefepime-zidebactam, cefiderocol, and murepavadin. ...
Apart from its role in intrinsic aminoglycoside resistance, mutation-driven hyperproduction of MexXY is a common driver of resistance to cefepime in clinical strains (39) . ...

A high-throughput systematic evolution of ligands by exponential enrichment assay was applied to 371 putative TFs in P. aeruginosa, which resulted in the robust enrichment of 199 sequence motifs describing ...
To further explore and delineate the physiological and pathogenic roles of TFs in P. aeruginosa, we constructed regulatory networks for nine major virulence-associated pathways, and found that 51 TFs were ...

The work presented herein shows that the home environment may serve as a reservoir for infection in patients with CF. ...
As patients age and disease progression occurs the diversity of organisms colonizing the lower airways generally decreases and patients become dominated by organisms such as Pseudomonas aeruginosa. ...
Recurrent mutations in different strains occurred in ftsl, the gene encoding penicillin binding protein 3 (PBP3) and negative regulators of the mexAB-oprM efflux system including mexR, nalD and nalC mutations ...
