Table 3. Zones of inhibition (mm) by antifungals for reference strains
Note: the reference ranges are provided in accordance with the instructions of the disk manufacturer (HiMedia; India) and confirmed during the method validation in laboratory settings; * ― sensitive dose-dependent.
Table 4. Sensitivity of Candida spp. clinical isolates to antifungal drugs, % (abs.) [95% CI]
Note: n — number of strains tested; the percentage of sensitive strains is specified in the cells, absolute numbers are specified in parenthesis, 95% confidence intervals are specified in square brackets; p (A vs. G) — comparison of C. albicans and C. glabrata; p (K vs. G) — comparison of C. krusei and C. glabrata; * — non-significant differences (p > 0.05).
