Abstract

Comparative effects of neem and lemongrass were investigated against isolated organism from the stool samples collected from patient suffering from typhoid fever. The isolated organism Salmonella shigella Agar (SSA) was used in carrying out sensitivity test using disc diffusion method and after the test the result was compared. Ethanol extracts of neem and lemongrass had minimum inhibitory concentrations (MIC) of 3.0μm/ml (3.0mm) and 6.0μm/ml (2.0mm) on neem and lemongrass respectively. Cold water extracts of neem and lemongrass had (MIC) minimum inhibitory concentrations of 12μm/ml (1.5mm) and 1.92μm/ml (0.9mm) respectively while hot water extracts of neem and lemongrass had MIC of 6.0μm/ml (1.2mm) and 12μm/ml (1.2mm) respectively. This research work revealed that neem could be more therapeutic than lemongrass on Salmonella shigella.
