Paris: Plastic surgery patients have carried a new class of superbugs resistant to almost all antibiotics from South Asia to Britain and they could spread worldwide, researchers reported Wednesday. Many hospital infections that were already difficult to treat have become even more impervious to drugs thanks to a recently discovered gene that can jump across different species of bacteria.This so-called NDM-1 gene was first identified last year by Cardiff University`s Timothy Walsh in two types of bacteria -- Klebsiella pneumoniae and Escherichia coli -- in a Swedish patient admitted to hospital in India.
The emergence of these new drug-resistant strains could become a serious global public health problem as the major threat shifts toward a broad class of bacteria -- including those armed with the NDM-1 gene -- known as "Gram-negative", the researchers warn."There are few new anti-Gram-negative antibiotics in development, and none that are effective against NDM-1," the study said.NDM-1 stands for New Delhi metallo-beta-lactamase-1.Johann Pitout from the University of Calgary in Canada said patients who have medical procedures in India should be screened for multi-resistant bacteria before they receive care in their home country.Bureau Report
