Research Introduction1: Survey of VBNC Vibrio cholerae contamination in environmental water and sewage

To clarify the route of human infection by an aquatic bacterium V. cholerae, our unit collects environmental water (water from ponds and rivers) and sewage in Kolkata, and investigates the Vibrio spp. and VBNC V. cholerae present in the water samples, as well as conducting research into the reversion to vegetative V. cholerae (V. cholerae that can be cultured using standard methods). In addition, we are investigating the distribution of genes such as toxins and pathogenic factors specific to V. cholerae, aiming to elucidate the process by which new V. cholerae strains emerge and spread.

Research Introduction2: Survey of Enterobacteriaceae contamination in livestock and poultry

In India, wild birds, chickens, dogs, goats, cows, and other animals are often seen on the streets, and their feces are leave on the streets. In previous studies, enterohemorrhagic Escherichia coli (EHEC), or Shiga toxin-producing Escherichia coli (STEC) has been frequently detected in bovine feces. Therefore, we are investigating Enterobacteriaceae in livestock and poultry feces, aiming to control the transmission and spread of fecal-borne pathogenic microorganisms to humans.

Research Introduction3: Animal and Environmental Surveillance and Rapid Diagnostic Development for Enteric Viruses in India: Addressing Diarrheal Diseases and Public Health

In India, enteric viruses such as rotavirus, norovirus, and enterovirus are major causes of diarrheal diseases, widely prevalent across the country.These viruses significantly impact children’s health and rural public health, with increasing research importance due to zoonotic transmission from animals and environmental spread through contaminated water and food.We aim to develop novel rapid diagnostic methods targeting viral RNA or proteins of these prevalent enteric viruses and conduct surveillance in wildlife, livestock, water sources, and soil. This will contribute to elucidating the reality of viral infections in regions with limited medical infrastructure and strengthening environmental management.

We also aim to develop novel rapid diagnostic methods of enteric viruses and conduct surveillance in wildlife, livestock, water sources, and soil. This will contribute to elucidating the reality of viral infections.
