Comparison of nephrotoxicity of Colistin with Polymyxin B administered in currently recommended doses: a prospective study

open access: yesAnnals of Clinical Microbiology and Antimicrobials, 2018
Background The most important concern with polymyxins (Colistin and Polymyxin B) use is nephrotoxicity. There is no prospective data comparing nephrotoxicity of these two drugs, when administered in high doses and as per current recommendations.

Elucidation of the RamA Regulon in Klebsiella pneumoniae Reveals a Role in LPS Regulation [PDF]

open access: yes, 2014
Klebsiella pneumoniae is a significant human pathogen, in part due to high rates of multidrug resistance. RamA is an intrinsic regulator in K. pneumoniae established to be important for the bacterial response to antimicrobial challenge; however, little ...

Lipopolysaccharide is a frequent contaminant of plasmid DNA preparations and can be toxic to primary cells in the presence of adenovirus [PDF]

open access: yes, 1994
Endotoxin (lipopolysaccharide, LPS) is commonly found as a contaminant in plasmid DNA preparations. We demonstrate here that the quantities of LPS typically contaminating DNA preparations can generate a toxicity to primary cells (primary human skin ...

Escenario actual de la resistencia a la colistina mediada por plásmidos en América Latina [PDF]

open access: yes, 2019
Colistin resistance can occur by chromosomal mutations and by acquisition of plasmid-carrying determinants, mainly mcr-1. In the recent years, we have observed the outburst of this resistance gene in our region. Due to the risk of the rapid dissemination

Polymyxin B-induced skin and nail hyperpigmentation in an adult

open access: yesPigment International, 2023
Polymyxin B is a reserve drug for resistant gram-negative bacterial infections. A rare side effect of polymyxin B is cutaneous hyperpigmentation, which characteristically involves face and neck. This is commonly reported in pediatric population.

Structural insights into Escherichia coli polymyxin B resistance protein D with X-ray crystallography and small-angle X-ray scattering [PDF]

open access: yes, 2014
BACKGROUND: Polymyxin B resistance protein D (PmrD) plays a key role in the polymyxin B-resistance pathway, as it is the signaling protein that can act as a specific connecter between PmrA/PmrB and PhoP/PhoQ.

Pharmacokinetic/Pharmacodynamic Based Breakpoints of Polymyxin B for Bloodstream Infections Caused by Multidrug-Resistant Gram-Negative Pathogens

open access: yesFrontiers in Pharmacology, 2022
The latest PK/PD findings have demonstrated negligible efficacy of intravenous polymyxins against pulmonary infections. We investigated pharmacokinetic/pharmacodynamic (PK/PD)-based breakpoints of polymyxin B for bloodstream infections and the ...

Peptides as potent antimicrobials tethered to a solid surface: Implications for medical devices [PDF]

open access: yes, 2008
Medical devices are an integral part of therapeutic management; despite their importance, they carry a significant risk of microbial infection. Bacterial attachment to a medical device is established by a single, multiplying organism, leading to ...

Evaluation of the interaction between polymyxin B and Pseudomonas aeruginosa biofilm and planktonic cells: reactive oxygen species induction and zeta potential

open access: yesBMC Microbiology, 2019
Background Although the most widely accepted mechanism of action for polymyxins is related to bacterial lysis via disruption, we hypothesized that this antimicrobial drug class could have other effects on Pseudomonas aeruginosa planktonic and sessile ...
