Colistin Sulfate (Mixture of A and B compound)
Cyclic polypeptide antibiotic produced by Bacillus polymyxa. Complex mixture of at least 30 components, primarily colistin A and B.Colistin (polymyxin E) is a polymyxin antibiotic produced by certain strains of Bacillus polymyxa var. colistinus. Colistin is a mixture of cyclic polypeptides colistin A and B. Colistin is effective against most Gram-negative bacilli and is used as a polypeptide antibiotic. Colistin is a decades-old drug that fell out of favor due to its nephrotoxicity. It remains one of the last-resort antibiotics for multidrug-resistant Pseudomonas aeruginosa, Klebsiella pneumoniae, and Acinetobacter.[1] New Delhi metallo- β-Lactamase multidrug-resi...ia cepaciaChryseobacteriu m indologen esEdwardsiel laElizabethkingia meningosepticaFrancise lla tularensis spp.Gram-negative cocciHelicobacter pyloriMoraxella catarrhalisNeisseria gonorrheae and Neisseria meningitidisProteusPro vide nciaSerratiaSome strains of Stenotrophomonas maltophilia[18]Gram-negative organisms with variable resistance to colistin: AeromonasVib rioPrevotellaFusobacte rium .
