Table 1 Effects of Progesterone on S. schenckii yeast and mycelium growth from conidia

From: Characterization and ligand identification of a membrane progesterone receptor in fungi: existence of a novel PAQR in Sporothrix schenckii

Progesterone concentration (mM) Average diameter of colonies incubated at 25°C (cm)a,b,c Average diameter of colonies incubated at 35°C (cm)a,b,c
0 2.40 ± 0.18 1.47 ± 0.13
0.010 2.35 ± 0.10 1.33 ± 0.11
0.050 2.10 ± 0.11* no growth
0.125 1.78 ± 0.07* no growth
0.250 1.47 ± 0.16* no growth
0.500 1.22 ± 0.11* no growth
  1. This table shows the colony diameter attained after conidia were inoculated at 25°C and 35°C in a modification of medium M agar plates with different concentrations of added progesterone. No growth was observed at concentrations of progesterone of 0.05 mM or above, at 35°C while conidia incubated at 25°C germinated and showed growth at all concentrations of progesterone tested. The data represents the average diameter ± one std deviation of 6 independent experiments.
  2. a The cultures were incubated at the desired temperature for 20 days.
  3. b All cultures were inoculated with 5μl of a suspension containing 106/μl conidia.
  4. c The values given are the average of 6 independent determinations.
  5. * The values marked with an asterisk are significantly different from the values where no progesterone was added to the medium.
