Descripción general

A selective supplement recommended by ISO Committee for the isolation of Listeria species.
Chemical structure: peptide

Aplicación

for the isolation of Listeria species

Acciones bioquímicas o fisiológicas

Mode of Action: Polymyxin B Sulfate binds to the lipid A portion of bacterial lipopolysaccharides†, disrupting the cytoplasmic membrane by inducing pores large enough to permit nucleotide leakage in bacterial walls. This disrupts the permeability of the cytoplasmic membrane.

Antimicrobial spectrum: Has bactericidal action on most gram-negative bacilli††, including E. Coli and on most fungi and gram-positive bacteria.

Componentes

Antibiotic resistance is an increasingly severe health problem. Antimicrobial peptides (AMPs) are being developed in order to overcome this problem, due lower bacterial resistance. Polymyxin B is an AMP with bactericidal effect on Gram-negative bacteria due to its high affinity

Changes in gene regulatory circuits often give rise to phenotypic differences among closely related organisms. In bacteria, these changes can result from alterations in the ancestral genome and/or be brought about by genes acquired by horizontal transfer. Here, we identify

Multidrug resistance in Pseudomonas aeruginosa is increasingly becoming a threat for human health. Indeed, some strains are resistant to almost all currently available antibiotics, leaving very limited choices for antimicrobial therapy. In many such cases, polymyxins are the only available
