A few weeks ago I received a culture of C. albicans to be used in
sensitivity testing for antibiotics. I have noticed that after incubation at
30 degrees C for a week, the colonies on the plate start to change colour
from creamy/white to dark olive green/black. I made a smear of some colonies
that remained white and compared them with the darker ones. The cells of the
darker colonies are very similar in shape and size to the cream-coloured
ones, but their walls are much thicker and dark olive green in colour. I
know that C. albicans has a tendency to switch colony morphologies but i
have not heard of it changing colour in this way. Do you think it might be
related to sporulation? Any suggestions would be greatly appreciated.
Thanks in advance.
