cause of mycotoxicosis?
ingestion of mycotoxins produced by fungi on food
mycotoxins are formed only in
particular environments or substrates and only by particular fungi

aspergillus flavus

grows on peanuts maize or wheat

produces aflatoxin B that induces acute aflatoxicosis
characteristics of aflatoxicosis
vomitting, abdominal pain, pulmonary edema, fatty infiltration, necrosis of liver
erythematous skin

cladosporium cladosporoides (monomorphic mold)

grows on fescue grass and produces toxin causing erythema of skin

claviceps purpurea

grows on rye, ergot alkaloids cause swollen inflamed muscles with pain and prikly sensation in limbs (gangrenous ergotism)
convulsive ergotism sx
itching, numbness, convulsions, death
alimentary toxic aleukia

fusarium nygamai

grows on prosomillet and wheat
alimentary toxic aleukia is caused by and characterized by
fusarium nygamai

hematopoietic system malfunctions (atrophy of bone marrow)
red mold and black spot disease

fusarium chlamydosporum

-ingested on contaminated wheat or barley

-sx include anorexia
cardiac beri beri

penicillium citreoviridaeis (monomorphic)
where is cardiac beriberi fungi ingested?
rice that produces citrinin

sx: include ascending paralysis and respiratory arrest known as cardiac beriberi
consumption of fleshy fungi (shrooms) that can result in different types of myetismus (fungal induced systemic poisonings)
mycestismus cerebralis
Paneolus Psilocybe and Stropharia

-symptoms begin 30 to 60 min after ingestion- changes in sensory perception, causes you to tripp

-only one that doesnt possibly cause death
mycestismus choleriformis
ingestion of Amanita and Galerina that produce vomiting and diarrhea within 6 to 24 hours after ingestion
mycestismus gastrointestinalis
caused by boletus, entoloma lactarius, lepiota and russula

V and D within 1 to 6 hours
mycestismus nervosa
after ingestion of amanita and inocybe

sx 1 to 2 hours after ingestion
including respiratory failure, death, convulsions salivation, coma
mycetismus sanguinarius
Helvella that resembles morchella

hemoglobinuria, hemolysis and jaundice 6 to 8 hours after ingestion
respiratory allergies to fungi are...
hypersensitivities to fungal spores or fungal products
air-conditioning lung caused by
inhalation of air conditioner water aerosols containing Aspergillus clavatus producing chronic cough and pneumonia
Asthma is caused by
Alternaria, Aspergillus, Curvularia, or Penicillium

IgE is produced to inhaled fungal spores resulting in antigen-antibody binding that activates mast cells causing bronchospasms
allergy caused by mushrooms, Coprinus and Schizophyllum resulting from inhalation of spores

chronic lung lesions, meningitis and endocarditis
Cheese-washer's disease
result of allergic rxn to cheese casings containing Penicillium casei that produces skin rashes
Farmer's lung
increased levels of IgG followed by repeated inhalation of hay containg Aspergillus or Penicillium spores resulting in acute symptoms of airway obstruction that includes cough with fibrotic deposits
allergic rxn to inhalation of spores of Lycoperdon or Calvatia species producing cough and pneumonitis
malt-workers disease
allergic rxn to molds barley containing Aspergillus species
maple bark stripper's disease
inhalation of cryptostroma corticale, which grows on bark of maple trees
mushroom-grower's lung
inhalation of spores of Pleurotus Ostreatus
occurs when humans inhale hay contaminated with Stachybotrys atra resulting in necrotic ulceration of mucosa due to production of trichothecene by fungus resulting in conjunctivitis, rhinitis, leukopenia
