Abstract: Cationic antimicrobial peptides were a class of small peptides with anti-extrogenous pathogen invasion. As an important component of congenital immune defense system against infections, they were widely distributed in vivo. It exhibited potent and broad-spectrum activities against both Gram-positive and Gram-negative bacteria, fungi, viruses, protozoa, and cancer cells,and normal eukaryotic cells with low toxicity. It was an ideal alternative to a new generation of antibiotics. However, the same as antibiotics, some bacteria were resistant to certain antimicrobial peptides. The antibacterial and drug-resistant mechanism of the cationic antimicrobial peptides were summarized in the article to provide certain reference.

Key words: cationic antimicrobial peptides; bacteria; antimicrobial mechanism; mechanisms of resistance
