Cationic Antimicrobial Peptide Resistance in Neisseria meningitidis [PDF]
ABSTRACT Cationic antimicrobial peptides (CAMPs) are important components of the innate host defense system against microbial infections and microbial products. However, the human pathogen Neisseria meningitidis is intrinsically highly resistant to CAMPs, such as polymyxin B (PxB) (MIC ≥ 512 μg/ml).

Interaction of Cationic Antimicrobial Peptides with Model Membranes [PDF]
A series of natural and synthetic cationic antimicrobial peptides from various structural classes, including alpha-helical, beta-sheet, extended, and cyclic, were examined for their ability to interact with model membranes, assessing penetration of phospholipid monolayers and induction of lipid flip-flop, membrane leakiness, and peptide translocation ...

Antimicrobial peptides: the role of hydrophobicity in the alpha helical structure [PDF]
The antimicrobial peptides (AMPs) are a class of molecule obtained from plants, insects, animals, and humans. These peptides have been classified into five categories: 1. Anionic peptide, 2. Linear alpha helical cationic peptide, 3.

Interaction of cationic antimicrobial peptides with Mycoplasma pulmonis [PDF]
We investigated the mode of action underlying the anti‐mycoplasma activity of cationic antimicrobial peptides (AMPs) using four known AMPs and Mycoplasma pulmonis as a model mycoplasma. Scanning electron microscopy revealed that the integrity of the M.
