Water microbiology is concerned with the microorganisms that live in water. Water may possess many pathogenic bacteria, viruses, protozoa and parasites. They are responsible for the emerging most widespread infections which are leading cause of death worldwide. Aeromonas veronii is commonly found in freshwater systems. Aeromonas is gram negative, facultative anaerobic bacteria. It causes aeromonasis in humans and is also pathogenic for aquatic and terrestrial animals. Pichola lake is one of the most beautiful lake of Rajasthan, India. It is an important source of potable water supply for the city. In the present study, an attempt has been made to isolate the lactobacilli from camel milk and detect the antibacterial activity of lactobacilli against previously isolated and identified Aeromonas veronii from lake Pichola. A total of 10 lactobacilli were isolated and subjected to agar well assay for detection of antibacterial activity. Out of them, 2 isolates showed demonstrable antibacterial activity against Aeromonas veronii. On the basis of biochemical and molecular characteristics these two isolates were identified as Lactobacillus rhamnosus CMU 14 and Lactobacillus fermentum CMU 17. Further investigation may reveal that these lactobacilli isolates could be used as potential probiotics for aquaculture and to manage aeromonasis.
