PEREIRA, Rogério Santos et al. Antibacterial activity of essential oils on microorganisms isolated from urinary tract infection. Rev. Saúde Pública [online]. 2004, vol.38, n.2, pp.326-328. ISSN 1518-8787. http://dx.doi.org/10.1590/S0034-89102004000200025.
The antibacterial activity of essential oils extracted from medicinal plants (Ocimum gratissimum, L., Cybopogum citratus (DC) Stapf., and Salvia officinalis, L.) was assessed on bacterial strains derived from 100 urine samples. Samples were taken from subjects diagnosed with urinary tract infection living in the community. Microorganisms were plated on Müller Hinton agar. Plant extracts were applied using a Steers replicator and petri dishes were incubated at 37°C for 24 hours. Salvia officinalis, L. showed enhanced inhibitory activity compared to the other two herbs, with 100% efficiency against Klebsiella and Enterobacter species, 96% against Escherichia coli, 83% against Proteus mirabilis, and 75% against Morganella morganii.
