Description:Magnified 475X, this India ink mounted photomicrograph revealed some of the ultrastructural details displayed by numerous Cryptococcus neoformans fungal organisms. Of importance in the implementation of this staining technique, is the enhancement it provides, enabling better observation of the organism’s outer capsular protective coating, which is revealed as a luminous ring surrounding each round-shaped fungal cell.
Cryptococcosis is an infection caused by fungi that belong to the genus Cryptococcus. There are over 30 different species of Cryptococcus, but two species – Cryptococcus neoformans and Cryptococcus gattii – cause nearly all cryptococcal infections in humans and animals. Although many people who develop cryptococcosis have weakened immune systems, some are previously healthy.
