Antimicrobial Effects of Essential Oils against Uropathogens with Varying Sensitivity to Antibiotics

Tripti Malik and Padma Singh    

Abstract: In the present study, the antimicrobial activity of five essential oils namely, basil, chamomile, geranium, lemongrass and thuja were determined against microorganisms isolated from patients having urinary tact infections. The inhibitory effect was evaluated for antibiotic sensitive and resistant bacterial urinary isolates and yeast isolate (Candida albicans). Geranium oil exhibited antimicrobial activity against all the isolates, highest diameter of inhibition zone was observed against Klebsiella pneumoniae and Staphylococcus aureus isolates. The lowest values of minimum inhibitory concentrations were determined for geranium oil against S. aureus (8.96 mg mL-1), Proteus mirabilis (17.92 mg mL-1), K. pneumoniae (35.88 mg mL-1) and P. aeruginosa (35.88 mg mL-1). Geranium essential oil also exhibited a strong bactericidal activity against the uropathogens, hence presents a preliminary justification for its therapeutic use for urinary tract infections.
