Effects of synthetic form of tracheal antimicrobial peptide on respiratory pathogens

Le résumé fourni par la source

We have synthesized a C-terminal portion of tracheal antimicrobial peptide (TAP) with 38 amino acids and tested it for efficacy on various clinical isolates of Pseudomonas aeruginosa strains from patients with cystic fibrosis and also on Aspergillus fumigatus. Our results indicate that the synthetic TAP has both potent bactericidal and fungicidal activities and that a combination of TAP and amphotericin B showed strong additive effects of growth inhibition on A fumigatus. These results suggest that TAP is potentially an effective therapy for Aspergillus and multi-drug-resistant Pseudomonas, pathogens that are often a serious threat to patients with cystic fibrosis.
