Culture of Aspergillus nidulans fungus
Aspergillus nidulans. Laboratory petri-dish culture of the fungus Aspergillus nidulans, cause of aspergillosis and mycetoma. Here the fungus is growing on agar in concentric circles from the centre outwards. The dark growth at the edges is the mycelium which forms the body of the fungus. The brown regions at the centre are spores, the reproductive bodies. A.nidulans produces the toxin sterigmatocysin which can cause food contamination. Inhalation of the spores causes the allergic lung reaction aspergillosis in asthmatics and those with lowered resistance. Mycetoma (madura foot) may result when the fungus infects tissue, bone and skin

EDITORS COMMENTS
This print showcases the intricate culture of Aspergillus nidulans fungus, a notorious cause of aspergillosis and mycetoma. The laboratory petri-dish culture reveals the fungus growing in concentric circles, emanating from the center outwards. At the edges, one can observe the dark growth known as mycelium, which forms the body of this fascinating organism. Intriguingly, at the center of this fungal masterpiece lie brown regions that represent spores – reproductive bodies crucial for its propagation. It is important to note that A. nidulans produces sterigmatocysin toxin, capable of contaminating food and posing health risks to consumers. The repercussions of encountering this fungus can be severe. Inhalation of its spores triggers an allergic lung reaction called aspergillosis among individuals with asthma or weakened immune systems. Furthermore, when A. nidulans infects tissue, bone, and skin, it may lead to mycetoma or "madura foot". This visually striking image not only highlights nature's extraordinary diversity but also serves as a reminder of how seemingly innocuous organisms can have profound effects on human health. By capturing both scientific intrigue and aesthetic beauty within a single frame, Science Photo Library provides us with yet another glimpse into our complex relationship with fungi – their potential dangers and their awe-inspiring existence in our world.
