| Abstract Most Escherichia coli strains live harmlessly in the intestines and rarely cause disease in healthy individuals. Nonetheless, a number of pathogenic strains can cause diarrhea or extraintestinal diseases both in healthy and immunocompromised individuals. Diarrheal illnesses are a severe public health problem and a major cause of morbidity and mortality in infants and young children, especially in developing countries. Myanmar has a rich pool of medicinal plants with traditional knowledge. This study, therefore, aimed to investigate the inhibitory activity of traditional Myanmar medicinal plants against E. coli. Firstly, the medicinal plants which treated diarrhea in Myanmar Traditional Medicine were investigated. Depending upon the information obtained from the investigation, the plants were collected from University of Yangon Campus, Nat-yekwin Village and Hla-pa-da Village (Hmawbi Township) and Hlawga National Park and then identified based on morphological characters of plants. Some plant materials are purchased from traditional drug shops and identified by organoleptic and microscopic evaluation methods of crude drugs. In this research, EtOH extracts of total 45 plant samples were used to screen the inhibitory activity against Escherichia coli with agar well diffusion method. The results of experiments showed that among the 45 plant samples, the leaf powder of Acacia concinna (Kin mon chin) was proofed to be most effective on the growth inhibition of Escherichia coli. The second and third most effective samples were bark powder of Terminalia chebula and fruit powder of Terminalia citrina. Leaves of Acalypha indica, rhizome of Zingiber montanum, seed of Piper nigrum, rhizome of Curcuma longa, leaves of Morinda angustifolia, leaves of Eclipta prostrata and leaves of Annona squamosa show weak activities on E. coli. Rhizome of Canna indica has no activity. |
