My objective is to explore and appreciate the beauty of living organisms, and to share these insights with a broader audience. My expertise lies in medical mycology, occupational health, space environmental medicine, and archaeological medical science.
Digital microscope image at 500x magnification of a Trichosporon asahii colony. Unlike hyphae in agar, aerial hyphae form spines.
The spines result from individual aerial hyphae aggregating and being enveloped by an extracellular matrix, ultimately forming transparent conical structures.

Digital microscope image of Scedosporium aurantiacum at 500x magnification. Conidia clustered together or lateral to hyphae, along with water droplets. It still closely resembles S. apiospermum.

Microscopic image (1000x magnification) of mature conidial masses of Trichoderma sp. obtained through cultivation from birch bark. The image showcases the characteristic jade-green conidial heads.

Culture of Fusarium solani isolated from a specimen of keratomycosis. Mucilage balls can be seen at the tips of conidiophores that extend vertically from droplets formed on potato dextrose agar medium. Microconidia, which are the source of infection, are visible within these mucilage balls.

Growth of Aspergillus clavatus observed at a 20x magnification after culturing for 11 days at 24°C from a respiratory specimen. The conidial heads are large. This fungus is known as a causative agent of allergic bronchopulmonary aspergillosis, but it is also known to cause other fungal infections.

I directly observed Aspergillus proliferans, which had grown on a piece of raw chocolate that my wife was about to eat, with a digital microscope. This fungus is isolated from environments with high viscosity. However, it might be underrecognized because it does not grow well on commonly used media.
