BAL specimen showing hyaline, septate hyphae consistent with Aspergillus, stained with Blankophor
-
Mucous plug examined by light microscopy with KOH, showing a network of hyaline branching hyphae typical of Aspergillus, from a patient with ABPA.
-
Corneal scraping stained with lactophenol cotton blue showing beaded septate hyphae not typical of either Fusarium spp or Aspergillus spp, being more consistent with a dematiceous (ie brown coloured) fungus
-
Corneal scrape with lactophenol cotton blue shows separate hyphae with Fusarium spp or Aspergillus spp.
-
A filamentous fungus in the CSF of a patient with meningitis that grew Candida albicans in culture subsequently.
-
Transmission electron micrograph of a C. neoformans cell seen in CSF in an AIDS patients with remarkably little capsule present. These cells may be mistaken for lymphocytes.
-
India ink preparation of CSF showing multiple yeasts with large capsules, and narrow buds to smaller daughter cells, typical of C. neoformans
