February 16, 2026—Antimicrobial resistance poses a growing global health crisis, with few new antibiotics in development. Researchers at Sultan Qaboos University have identified three novel antimicrobial peptides (AMPs) from dromedary camels that effectively target multidrug-resistant bacteria, offering potential alternatives to conventional drugs.
Published in Frontiers in Immunology (Volume 17, 21 January 2026), the study combined bioinformatics predictions with experimental validation, including colony-forming assays, membrane permeability tests, and electron microscopy on strains like MRSA and MDR E. coli.
Peptides CdPG-3 and CdCATH demonstrated strong antibacterial activity across Gram-positive and Gram-negative bacteria, causing membrane damage and leakage without high toxicity to camel or human red…
