Abstract

The main objective of the present study is to investigate antibacterial activity of a probiotic Lactobacillus plantarum against urinary tract infection causing pathogens. The proteinaceous substance produced by the probiotic strain is highly effective against all the urinary tract infecting pathogens used in the study. The cell free supernatant of the L.plantarum bacteria is able to inhibit the growth of Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae and Pseudomonas aeruginosa. The recorded inhibitory zone was ranged from 16 mm to 26 mm against urinary tract infecting pathogens. Results from this study concluded that the compound bacteriocin produced by L. plantarum have the potential to inhibit urinary tract infecting pathogens.

Keywords: L.plantarum, E.coli, Staphylococcus aureus, Klebsiella pneumoniae and Pseudomonas aeruginosa.
