The <em>in-vitro </em>antimicrobial activities of the ethanol and methanol extracts of the betel leaf were noticeable against tested bacteria. Among 3 categories of samples, the antibacterial action of ethanol extracts of hot betal leaf was found the highest against most of the bacteria except <em>Klebsiella </em>sp. and <em>Staphylococcus </em>sp., while the methanol extract showed antibacterial activity against all the pathogenic strains tested. The highest MIC (1mg/ml) and the lowest MIC values (25mg/ml) of hot betel leaf and sweet betel leaf were found against <em>E. coli </em>and all test organisms, respectively. This evidence revealed that betel leaf extracts can be used to combat against human pathogens.</p><p>Bangladesh J Microbiol, Volume 34 Number 2 December 2017, pp 125-127</p> ER -
