I am Ritam Guha, a Ph.D. student at Cochin University of Science and Technology, India, and working as a project associate in an Indo-Taiwan Project at the same university under the guidance of Dr. Preetham Elumalai. I have completed my postgraduation in Marine Biotechnology from Bharathidasan University, Tamilnadu, India. My study focused on developing a novel vaccine delivery system to combat antimicrobial-resistant Streptococcus sp. in Tilapia Farms in India. I am experienced in several Molecular and biotechnological tools to develop a vaccine. Aquatic vaccines are essential to prevent several bacterial pathogen outbreaks and save the farms' crops. In the increasing era of antimicrobial-resistant strains of bacteria following viruses, where vaccines can be utilized as safe and targeted preventive measures for fish. My research emphasizes how a cheap but effective vaccine can be developed and utilized commercially to serve farmers and to save aquatic crops. Also, the implementation of novel molecular techniques to formulate vaccines is another aspect of this approach to be in flow with the one health approach.
