Probiotics are live bacteria that confer good health benefits to their host. Probiotics help in restoring the gut microbiota. A Probiotic bacterium inhibits the pathogen’s growth and their attachment to the intestine or gastrointestinal tract. They help in the permeability of the intestine and increase the production of mucosa and intestinal integrity. In this study, it is an attempt to analyze the antibacterial effect of probiotic bacteria against common human pathogens. Eleven probiotic isolates were isolated from three different natural samples and they were characterized based on Colony Characteristics, Cell morphology, Staining properties and catalase test. The antibacterial activity of the probiotic isolates was determined against four human pathogens through the agar well diffusion method. Almost all the probiotic samples exhibited antibacterial activity against the tested bacteria.
