A team led by Ashis K. Mukherjee at the Institute of Advanced Study in Science and Technology (IASST), Guwahati, reports progress toward an antivenom for the Indian black scorpion Heterometrus bengalensis. The glossy black scorpion lives mainly in tropical and subtropical regions. Scorpion stings are a global problem and can cause severe illness.
The researchers used spectrometry and biochemical analysis to map the venom and discovered 25 distinct toxins across eight protein families. Susmita Nath, a team member, said this is a first step toward an antivenom that could work for more than one species, and the lab is working to produce an antidote.
Tests on Swiss albino mice showed systemic toxicity, increased liver enzymes, organ damage and inflammation. Mukherjee described a "toxic storm" in the mice and said the signs could point to shock or severe allergic reactions in real-world stings. The authors call for improved therapeutic strategies and plan to build a reference database of venom proteins to support further research.
