Fig. 8From: Genomic analysis of qnr-harbouring IncX plasmids and their transferability within different hosts under induced stressInfluence of induced stress on IncX1 A and IncX2 B plasmid conjugative transfer. Frequency of transfer was calculated as the number of transconjugants per the number of donors (T/D). LB stands for Luria–Bertani agar. CIP represents the concentration (µg/mL) of supplemented ciprofloxacin into the media. Due to high differences in transfer frequencies the lower values are not clearly depicted. Exact values are specified in Table 2Back to article page
