Figure 2. Agarose gel electrophoresis of integrase gene polymerase chain reaction (PCR) amplification products. A: PCR products of class 1 integrase gene intI1. Lane M; molecular marker; lanes 1 and 19: no template (negative) control; lanes 2 and 20: positive control (In2); lanes 3–36: multiple drug–resistant isolates. B: PCR products of class 2 integrase gene intI2. Lane M: molecular marker; lanes 1 and 19: no template control (negative) control; lanes 2 and 20: positive control (Tn7); lanes 3–36: multidrug-resistant isolates.
