    El efecto antimicrobiano del aceite esencial de canela (Cinnamomum zeylanicum) sobre cepas de Salmonella choleraesuis y Salmonella typhimurium fue investigado. El aceite de canela se obtuvo a trav茅s del m茅todo de destilaci贸n por arrastre de vapor y sometido a decantaci贸n, almacen谩ndolo en refrigeraci贸n a 4 掳C. Se aplic贸 un dise帽o completamente al azar con cinco tratamientos (10, 30, 50, 70 90% de aceite de canela) y cinco repeticiones. La Concentraci贸n M铆nima Inhibitoria determinada del extracto se verific贸 al 50, 70 y 90% del aceite. En agar Mueller-Hinton se observ贸 cero crecimientos de colonias con respecto a la Concentraci贸n Bactericida M铆nima. La cepa Salmonella typhimurium present贸 mayor sensibilidad al aceite de canela que la cepa Salmonella choleraesuis, en referencia al di谩metro de los halos de sensibilidad.The antimicrobial effect of cinnamon essential oil (Cinnamomum zeylanicum) on strains of Salmonella choleraesuis and Salmonella typhimurium was evaluated. The cinnamon oil was obtained by the method of steam distillation, decanted, and stored at 4 掳C. A completely randomized design was applied with five treatments (10, 30, 50, 70, 90% of cinnamon oil) and five replicates. The determined Minimum Inhibitory Concentration of the extract was verified at 50, 70 and 90% of the oil. On Mueller-Hinton agar, zero colony growth was observed with respect to the Minimum Bactericidal Concentration. The strain Salmonella typhimurium presented greater sensitivity to cinnamon oil than the strain Salmonella choleraesuis in relation to the diameter of the halos of sensitivity
