• Aspergillus forms fruiting bodies and septate filaments branching at acute angles
  • Candida grows as yeast forms, tandem arrays of elongated forms without hyphae (pseuhyphae) and true hyphae with septate
  • Actinomyces is a gram-positive filamentous or rod-shaped bacteria
  • Mucormycosis form non-septate, irregularly wide fungal hyphae with frequent right-angle branching. In addition mucormycosis frequently occur in diabetics and may spread from nasal sinuses to the orbit and brain giving rise to rhinocerebral mucormycosis.
