Cryptococcus neoformans: Negative Staining




India ink preparation of CSF, showing Cryptococcus neoformans (low-power view). The capsule can be seen as a clear halo around the organism.

The patient was an immunodeficient 54-year-old female.

This technique, while specific, is not very sensitive. Fungal culture is more sensitive.

The picture below shows the high-power view.
