Complement fixation, immunodiffusion.
Pseudallescheria spp, fusariosis.
• Allergic bronchopulmonary aspergillosis—Hypersensitivity reaction to the fungus and most common in asthmatics.
• Saprophytic aspergillosis (Aspergilloma)—Most common form; noninvasive; colonisation of pre-existing cavities.
• Chronic necrotising aspergillosis—Airway-invasive aspergillosis; semi-invasive aspergillosis; chronic cavitary pneumonic disease (often affects patients with preexisting chronic lung disease).
• Angioinvasive aspergillosis—Affects immunocompromised patients and is often fatal.

Widely spread in the environment, a fungal species found in the soil or decaying vegetation; most common cause of aspergillosis in humans, particularly in the immunocompromised patient. Associated with pulmonary, bone, ocular, nasal, and deep organ disease; extremely angioinvasive.
a genus of fungi (molds), several species of which are parasitic and opportunistic pathogens. Others produce toxins and when they contaminate animal feeds they can cause heavy losses. Includes A. amstelodami, A. chevalieri, A. clavatus, A. flavus oryzae, A. fumigatus, A. maydis, A. niger, A. ochraceus, A. parasiticus, A. taumanii, A. wentii.
