A strain of tuberculosis (TB), wholly resistant to antibiotics has been reported and confirmed in India among patients from the slums of Mumbai.
Drug-resistant strains have emerged before in Italy and Iran and multiple-resistant strains have been seen in China and Russia. This emergent strain has meant 12 patients have failed to respond to any antibiotics despite months of treatment. Three have died, the BBC reports.
The American Centers for Disease Control CDC confirmed that the Indian strain appears to be fully resistant to available antibiotics, the BBC says.
