The team then tested the new peptide’s effect on the growth of several disease-causing bacterial species, including E coli, Salmonella Typhimurium, Staphylococcus aureus, and a multidrug-resistant strain of Acinetobacter baumannii, both in cell culture and animal models, in collaboration with the lab of Dipshikha Chakravortty, Professor at the Department of Microbiology and Cell Biology (MCB). They also compared the effect of their peptide against clinical doses of ciprofloxacin.
