This image was captured in 2005, by Centers for Disease Control and Prevention (CDC) Health Scientist, Ginger L. Chew, Sc.D., and depicts a culture plate, which contained malt extract agar (MEA) that had been inoculated with an air sample obtained on a filter membrane inside a home flooded by Hurricane Katrina, and which exhibited visible mold growth on its walls and furnishings. After incubation, the culture gave rise to these mold colonies, which varied in size, color, and texture. The black colonies were the fungal microorganism Aspergillus niger, the large green colony was a species of Trichoderma, and the white colony was an unidentified fungal species.
“Mold can cause fungal allergy and respiratory infections or worsen certain illnesses such as asthma. Molds are microorganisms that are found virtually everywhere, indoors and outdoors. The potential health effects of exposure to indoor mold are of increasing concern. Nevertheless, no conclusive evidence exists that inhalation of indoor mold is associated with a multitude of other health problems, such as pulmonary hemorrhage, memory loss, and lack of energy.”
