Fig. 2.
Association between ESBL positivity and combinations of resistance genes blaOXA, blaCTXM and blaTEM. Black circles represent ESBL positive and/or the detection of resistance genes of blaOXA family, blaCTXM family or blaTEM. A grey circle indicates that a characteristic was not detected. The vertical bars indicate the number of isolates in the group summarized directly below. The horizontal bars indicate the total number of isolates positive for resistance genes of blaOXA family, blaCTXM family, blaTEM or for ESBL positivity. An isolate was classified as blaOXA positive if any gene of blaOXA family was detected. The same is true for blaCTXM genes. Only the isolates that were tested for ESBL positivity, at least one member of blaOXA family, at least one member of blaCTXM family and blaTEM were included
