Abstract: 
The increase in the resistance of bacteria to antibiotics represents a priority problem to be addressed for humanity because it causes infectious diseases to become increasingly difficult or impossible to treat, which could lead to a reduction in the hope and quality of life. For this reason, medicinal plants have become a great alternative in the treatment of infections and in reducing bacterial resistance, this through the search for new compounds present in various plant species. Kalanchoe daigremontiana is a species of plant from the Crassulaceae family, native to Madagascar. Various studies have shown that this plant has a potential antimicrobial effect against strains of medical importance. The objective of this study was to evaluate the antimicrobial effect of a methanolic extract of Kalanchoe daigremontiana against a registered strain of Salmonella typhi. A methanolic extract was obtained with a concentration of 1.5 g/mL. The extract had a notable effect against Salmonella typhi ATCC 6589 with an inhibition percentage of 41.7% for the concentration used, so it is considered that the Kalanchoe daigremontiana extract has the potential to be used as an antibiotic.
