The misuse and overuse of antibiotics in medicine and agriculture has led to the emergence of antibiotic resistant bacteria.
“My major interest in life is to discover new treatments for infection in the face of antibiotic resistance,” says Bob Hancock, a microbiologist at UBC and the Canada Research Chair in Pathogenomics and Antimicrobials.
Hancock is studying short strings of amino acids, called peptides. He started with the smallest known peptide and tweaked it until its activity had increased. The improved version boosts the immune system and helps the body fight off infection.
