Microbiology: Fungi Mycotoxicosis, Mycetismus And Allergies

Front 1

cause of mycotoxicosis?

Back 1

ingestion of mycotoxins produced by fungi on food

Front 2

mycotoxins are formed only in

Back 2

particular environments or substrates and only by particular fungi

Front 3

aflatoxicosis

Back 3

(mycotoxicosis)

aspergillus flavus

grows on peanuts maize or wheat

produces aflatoxin B that induces acute aflatoxicosis

Front 4

characteristics of aflatoxicosis

Back 4

vomitting, abdominal pain, pulmonary edema, fatty infiltration, necrosis of liver

Front 5

erythematous skin

Back 5

(mycotoxicosis)

cladosporium cladosporoides (monomorphic mold)

grows on fescue grass and produces toxin causing erythema of skin

Front 6

ergotism

Back 6

(mycotoxicosis)

claviceps purpurea

grows on rye, ergot alkaloids cause swollen inflamed muscles with pain and prikly sensation in limbs (gangrenous ergotism)

Front 7

convulsive ergotism sx

Back 7

itching, numbness, convulsions, death

Front 8

alimentary toxic aleukia

Back 8

(mycotoxicosis)

fusarium nygamai

grows on prosomillet and wheat

Front 9

alimentary toxic aleukia is caused by and characterized by

Back 9

fusarium nygamai

hematopoietic system malfunctions (atrophy of bone marrow)

Front 10

red mold and black spot disease

Back 10

(mycotoxicosis)

fusarium chlamydosporum

-ingested on contaminated wheat or barley

-sx include anorexia

Front 11

cardiac beri beri

Back 11

(mycotoxicosis)

penicillium citreoviridaeis (monomorphic)

Front 12

where is cardiac beriberi fungi ingested?

Back 12

rice that produces citrinin

sx: include ascending paralysis and respiratory arrest known as cardiac beriberi

Front 13

mycophagy

Back 13

consumption of fleshy fungi (shrooms) that can result in different types of myetismus (fungal induced systemic poisonings)

Front 14

mycestismus cerebralis

Back 14

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

Front 15

mycestismus choleriformis

Back 15

ingestion of Amanita and Galerina that produce vomiting and diarrhea within 6 to 24 hours after ingestion

Front 16

mycestismus gastrointestinalis

Back 16

caused by boletus, entoloma lactarius, lepiota and russula

V and D within 1 to 6 hours

Front 17

mycestismus nervosa

Back 17

after ingestion of amanita and inocybe

sx 1 to 2 hours after ingestion
including respiratory failure, death, convulsions salivation, coma

Front 18

mycetismus sanguinarius

Back 18

Helvella that resembles morchella

hemoglobinuria, hemolysis and jaundice 6 to 8 hours after ingestion

Front 19

respiratory allergies to fungi are...

Back 19

hypersensitivities to fungal spores or fungal products

Front 20

air-conditioning lung caused by

Back 20

inhalation of air conditioner water aerosols containing Aspergillus clavatus producing chronic cough and pneumonia

Front 21

Asthma is caused by

Back 21

Alternaria, Aspergillus, Curvularia, or Penicillium

IgE is produced to inhaled fungal spores resulting in antigen-antibody binding that activates mast cells causing bronchospasms

Front 22

Basidiomycosis

Back 22

allergy caused by mushrooms, Coprinus and Schizophyllum resulting from inhalation of spores

chronic lung lesions, meningitis and endocarditis

Front 23

Cheese-washer's disease

Back 23

result of allergic rxn to cheese casings containing Penicillium casei that produces skin rashes

Front 24

Farmer's lung

Back 24

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

Front 25

Lycoperdonosis

Back 25

allergic rxn to inhalation of spores of Lycoperdon or Calvatia species producing cough and pneumonitis

Front 26

malt-workers disease

Back 26

allergic rxn to molds barley containing Aspergillus species

Front 27

maple bark stripper's disease

Back 27

inhalation of cryptostroma corticale, which grows on bark of maple trees

Front 28

mushroom-grower's lung

Back 28

inhalation of spores of Pleurotus Ostreatus

Front 29

Stachybotryotoxicosis

Back 29

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
