The increasing prevalence of acquired carbapenemases in Gram – negative bacteria is one of the biggest problems in the prevention and therapy of infectious diseases. NDM (New Delhi Metallo--Lactamase) is a recently discovered enzyme which has the ability to hydrolyze all -lactam antibiotics, except aztreonam. Making that scenario more worrisome is the fact that mobile fragments of DNA carrying blaNDM genes, also keeps a number of other genes encoding antibiotic resistance. NDM enzymes are currently present in different species of bacteria all over the world. NDM-producing bacteria are resistant to virtually all available antimicrobial agents except tigecycline, colistine and fosfomycine
