Two genes, <span class="elsevierStyleItalic">aac (6′)-II</span> and <span class="elsevierStyleItalic">ant (2″)-I,</span> were the most frequent resistance genes observed in these isolates.

On the other hand, we detected 15 isolates which co-harbored two, three, or four aminoglycoside-modifying enzyme genes simultaneously, which is in contrast to several studies conducted in the USA and Europe, which reported that the majority of isolates exhibit only a single aminoglycoside modifying gene.<a class="elsevierStyleCrossRef" href="#bib22">22</a></p><elsevierMultimedia ident="tbl2"></elsevierMultimedia><p id="para110" class="elsevierStylePara elsevierViewall">Miller et al. brought together the results of several studies of aminoglycoside resistance in <span class="elsevierStyleItalic">P. aeruginosa</span> carried out worldwide.<a class="elsevierStyleCrossRef" href="#bib22">22</a> Their results indicated that in Europe, <span class="elsevierStyleItalic">aac(6′)-II</span> was the most prevalent resistance gene (32.5%), followed by <span class="elsevierStyleItalic">ant(2″)-I</span> (16.9%).
