LONDON: Some 77 cases of a multi-drug resistant "superbug" from India first reported in Britain in August have now been detected in 13 European countries, a scientist at the EU's disease watchdog said on Wednesday.

Dominique Monnet of the European Centre for Disease Prevention and Control (ECDC) said he was very worried by the emergence of NDM-1, or New Delhi metallo-beta-lactamase, and other bugs like it that are resistant to even the most powerful class of antibiotics, known as carbapenems.
