Lactic acid bacteria are a heterogeneous group of microorganisms having in common the production of lactic acid as an end product of metabolism. Lactococcus lactis as probiotics bacteria are being increasingly studied for their inhibitory activity against pathogenic bacteria. The aim of this study is to investigate the inhibitory effect of lactic acid bacteria, we studied the antagonistic activity of Lactococcus lactis strains isolated from raw cow�s milk from the region of Mostaganem (western Algeria) by the method of agar well diffusion against Escherichia coli obtained from urinary tract infection (UTI) patients, UTI is considered as the most common bacterial infection. The interaction between Lactococcus lactis and Escherichia coli has led to the appearance of important areas of inhibitions with diameters varying among 09 and 20 mm. In order to detect the nature of the inhibitory agent, other additional testes were taken. The results obtained are encouraging and take into consideration; as well it showed the activity of antibacterial substances of this probiotic towards the pathogenic species causing urinary tract infections.
