Opis ogólny

Chemical structure: peptide

Zastosowanie

Colistin sulfate is used to permeabilize bacterial cell membranes and to study mannose-resistant haemagglutination and antibiotic resistance in certain organisms such as A. baumannii . It has been used to study hephrotoxicity in the rat kidney , and MICs, time-kill kinetics, and postantibiotic effect (PAE) against Pseudomonas aeruginosa .

Działania biochem./fizjol.

Mode of Action: Binds to lipids on the cell cytoplasmic membrane of Gram-negative bacteria and disrupts the cell wall integrity.
Antimicrobial spectrum: Gram-negative bacteria.
Mode of Action: Binds to lipids on the cell cytoplasmic membrane of Gram-negative bacteria and disrupts the cell wall integrity.
Antimicrobial spectrum: Gram-negative bacteria. It is proposed that renal reabsorption of colistin may involve organic cation transporters and peptide transporters and that the process is sensitive to pH .

Colistin is considered a last-hope antibiotic against extensively drug-resistant isolates of Acinetobacter baumannii. Resistance to colistin has been rarely reported for A. baumannii. Genetic alterations in the PmrA-PmrB two-component system and lipid A biosynthesis genes may be associated with colistin

Bacterial resistance to classical antibiotics is emerging worldwide. The number of infections caused by multidrug resistant bacteria is increasing and becoming a serious threat for human health globally. In particular, Gram-negative pathogens including multidrug resistant Escherichia coli are of serious
Candace M Marr et al.
Frontiers in microbiology, 11, 595798-595798 (2020-11-17)
Acinetobacter baumannii is a problematic pathogen due to its common expression of extensive drug resistance (XDR) and ability to survive in the healthcare environment. These characteristics are mediated, in part, by the signal transduction system BfmR/BfmS. We previously demonstrated, in

Antimicrobial agents and chemotherapy, 60(11), 6867-6871 (2016-09-08)
Persisters are small populations of quiescent bacterial cells that survive exposure to bactericidal antibiotics and are responsible for many persistent infections and posttreatment relapses. However, little is known about how to effectively kill persister bacteria. In the work presented here

Science advances, 5(7), eaax1946-eaax1946 (2019-07-30)
Drug resistance is a public health concern that threatens to undermine decades of medical progress. ESKAPE pathogens cause most nosocomial infections, and are frequently resistant to carbapenem antibiotics, usually leaving tigecycline and colistin as the last treatment options. However, increasing
