Effect of Desmodium Triquetrum extract on some pathogenic bacteria

ABSTRACT

An aqueous extract of Desmodium triquetrum was tested against Salmonella typhi, s. paratyphi A, s. paratyphi B, Shigella boydii, s. flexneri, S. shigae, Vibrio eltor, V. cholerae (Inaba serotype), V. cholerae (Ogawa serotype) and Escherichia coli by the serial dilution tube technique. The extract was found to have bactericidal action on the ten bacteria tested. The range of minimum inhibitory concentration (MIC) values was also determined compared with values for streptomycin, chloramphenicol and tetracycline. Large-scale growing of D. triquetrum is suggested to facilitate analysis and identification of the anti-bacterial principle.
