Figure 2: Gel electrophoresis of polymerase chain reaction products of the carbapenem-resistant isolates using New Delhi metallo-beta-lactamase -1 primer. M =100 bp DNA ladder; 1 = New Delhi metallo-beta-lactamase -1 negative isolate; 2, 3 and 4 = New Delhi metallo-beta-lactamase - 1 positive strains; C = Negative control. All the isolates in the gel were resistant to carbapenems and each lane number corresponds to the isolate number in Table 2 |
