Description: | This 1971 photograph depicts the reverse (bottom) view of a Petri dish in which was growing a Penicillium marneffei fungal colony. Note the darkened interior pigment that lightens to a red-orange, then to a cream coloration, as the colony radiates outward from the center. Known to cause disease in the immunocompromised, or chemotherapy patient, the fungus P. marneffei, is endemic to Southeast Asia, where it is one of the more common HIV-related opportunistic infections. |
