Current Research: 

Pathogens transmitted from animals to human via contaminated food and water cause up to 33 million cases (>50% of human infectious diseases) of reported illness each year in North America. Six bacterial species including Campylobacter jejuni, Enerohemorrhagic Escherichia coli (EHEC), non-typhoid Salmonella spp., Listeria monocytogenesClostridium perfringens andStaphylococcus aureus account for over one half of the illness.

Reducing levels of these bacterial pathogens in food-producing animals and prevent the cross contamination in the food processing plants are effective ways to reduce food safety risks for humans. Dr. Biswas’s research projects focused on the reduction of pre- and post-harvest levels of colonization and contamination these foodborne bacterial pathogens in foods specifically meat and meat products and development of vaccines that prevent colonization of animals by E. coli O157, C. jejuni and Salmonella enterica species which may reduce human gastrointestinal infections. In addition, Dr. Biswas’s researches also focus to develop the monoclonal antibodies against foodborne bacterial pathogens to improve the detection of pathogens in food and other polluted materials.

Lab Information: 

Pathogens transmitted from animals to human via contaminated food and water cause up to 33 million cases (>50% of human infectious diseases) of reported illness each year in North America. Six bacterial species including Campylobacter jejuni, Enerohemorrhagic Escherichia coli (EHEC), non-typhoid Salmonella spp., Listeria monocytogenesClostridium perfringens andStaphylococcus aureus account for over one half of the illness. Reducing levels of these bacterial pathogens in food-producing animals and prevent the cross contamination in the food processing plants are effective ways to reduce food safety risks for humans.

Dr. Biswas’s research projects focused on the reduction of pre- and post-harvest levels of colonization and contamination these foodborne bacterial pathogens in foods specifically meat and meat products and development of vaccines that prevent colonization of animals by E. coli O157, C. jejuni and Salmonella enterica species which may reduce human gastrointestinal infections. In addition, Dr. Biswas’s researches also focus to develop the monoclonal antibodies against foodborne bacterial pathogens to improve the detection of pathogens in food and other polluted materials.
