Tuberculosis (TB) remains a leading cause of death despite the availability of drug treatments. Antibiotic resistance and genetic mutation has led to the development of both multi drug-resistant and extensively drug-resistant tuberculosis, further complicating successful intervention. Antimicrobial peptides (AMPs) present a novel alternative to standard antibiotic therapies. In this study, we used flow cytometry to measure the cytotoxicity of three different AMPs (A4S7, D8 and WLBU2) on three types of host cells associated with Tb infection. Both WLBU2 and A4S7 were associated with significant cell death (p < 0.05) at and above concentrations of 10μM, and the results for D8 fluctuated by cell type. The data obtained in this study will inform future replications in bacterial models, from which the plausibility of specific AMPs as treatments for Mycobacterium tuberculosis can be assessed and provide insights of clear public health significance.
