MBT showed antibacterial activity in vitro with MICs of 64 μg/mL (a strain of Salmonella typhi (ATCC 6539)), 128 μg/mL (Salmonella typhi), 64 μg/mL (Salmonella paratyphi A), 128 μg/mL (Salmonella paratyphi B) and 64 μg/mL (Salmonella typhimurium). The results showed that MBT demonstrated moderate in vitro antibacterial activity against a strain of Salmonella typhi (ATCC 6539), Salmonella paratyphi A, and Salmonella typhimurium, indicating its promise as a possible lead for the discovery of antibacterial drugs.展开更多
