Conditions inducing white cell filamentation do not induce opaque cell filamentation.

<p>Environmental cues that induce efficient filamentation in <i>C. albicans</i> white cells (RBY717) include serum (A), high temperature (B), Spider medium (C and F), neutral pH medium (D), and Lee's medium (E). None of these environmental cues induce filamentous growth in opaque cells. Cell photographs were taken after 5 hours incubation at 37°C except for YPD supplemented with serum (2 hour incubation). Colonies grown on Spider medium were incubated at 30°C for 4 days.
