Figure 9. Fitness assays between azole-resistant and azole-susceptible isolates.

Figure 9

(A) In vitro fitness assays. Strains SFY114 (DSY562 pdr1Δ-PDR1) and SFY115 (DSY562 pdr1Δ-L280F) were inoculated in YEPD in single or mixed (1∶1) cultures. Aliquots were taken from each culture in triplicate and population ratios were calculated from the proportion of azole-susceptible and azole-resistant colonies plated onto YEPD agar as described in Material and Methods. (B) In vivo fitness assays. SFY114 (DSY562 pdr1Δ-PDR1) and SFY115 (DSY562 pdr1Δ-L280F) were inoculated intravenously as single or mixed (1∶1) cultures to three groups of mice as described in Material and Methods. Kidneys were taken at given time points from sacrificed mice and population ratios were measured as described above.
