Antibacterial activities of Emblica officinalis and Coriandrum sativum against Gram negative urinary pathogens.

Present investigation is focused on antibacterial potential of aqueous infusions and aqueous decoctions of Emblica officinalis (amla) and Coriandrum sativum (coriander) against 345 bacterial isolates belonging to 6 different genera of Gram negative bacterial population isolated from urine specimens by employing well diffusion technique. Aqueous infusion and decoction of Emblica officinalis exhibited potent antibacterial activity against Escherichia coli (270), Klebsiella pneumoniae (51), K. ozaenae (3), Proteus mirabilis (5), Pseudomonas aeruginosa (10), Salmonella typhi (1), S. paratyphi A (2), S. paratyphi B (1) and Serratia marcescens (2) but did not show any antibacterial activity against Gram negative urinary pathogens.
