IIM Calcutta Startup Develops Bengal-Specific Snake Antivenom Treatment
Snake venom can be different in different parts of India.
Most antivenom makers use venom collected in two Tamil Nadu districts.
Some experts worry that this may make treatment less effective for snakebites in Bengal.
Monosha Biotech is collecting venom from snakes found in Bengal.
It operates a venom laboratory in Baruipur with government cooperation.
The venom will be given to pharmaceutical companies to help make a regional antivenom.
A Bengal health expert said many snakebite deaths involve Russell’s vipers.
The company hopes its first commercial product will be available by 2028.
Monosha Biotech is developing a Bengal-specific antivenom using venom collected from snakes in the state.
Most Indian antivenom manufacturers obtain venom from Chengalpattu and Kanchipuram in Tamil Nadu.
Experts say regional differences in snake venom may create gaps in the effectiveness of standard antivenoms.
The startup received permission to collect snakes and extract venom in 2020, working with Bengal’s forest and health departments.
Monosha’s co-founder Saurabh Ray said the first commercial batch could reach the market by 2028.

Treatment effectiveness
Regional Antivenom Advocates
Monosha Biotech and Bengal experts argue that venom differs by region and that a Bengal-specific antivenom could address treatment gaps.
Existing Antivenom System
The existing system uses polyvalent antivenom made from venom of four medically significant snake species and is administered under national and state protocols.
Evidence for change
Regional Antivenom Advocates
Somnath Das said some patients die despite following guidelines and that there is a strong case for a regional antivenom, particularly because Russell’s vipers cause many Bengal bites.
Existing Antivenom System
The state health department continues to source antivenom from pharmaceutical companies and has sought market interest in region-specific products without yet identifying a final supplier.
