Sulphur dioxide, pretty notorious as a gaseous pollutant, may potentially have a role to play in tackling tuberculosis (TB), according to a recent paper by researchers at the Indian Institute of Science Education and Research (IISER), Pune. Their findings, potentially, open the door to the development of various sources of sulphur dioxide in the treatment of the infectious disease that affects millions globally every year.

Research into novel approaches to treat TB is driven by the need to tackle multi-drug-resistant strains of Mycobacterium tuberculosis (Mtb), the pathogenic bacterial species that causes the disease
