mycotoxicosis Flashcards
(46 cards)
secondary fungal metabolites
Mycotoxin
Manifests as acute or chronic
disease, usually tumor formation;
carcinogenic
Mycotoxin
PRESENTING SYMPTOMS AND SEVERITY DEPEND ON:
- mycotoxin
- Amount and duration of exposure
- Route of exposure
- Age, sex and health of the exposed individual
- malnutrition, alcohol
abuse, infectious disease status, and other toxin
exposures may act synergistically to compound
is there treatment for mycotoxin?
Supportive therapy, there are almost no treatments for
mycotoxin exposure
It is communicable person to person?
No
red mold disease
Akakabi-byo
MYCETISM also known as
mycetismus
Mushroom poisoning
MYCETISM
This accounts for the majority of fatal
mushroom poisonings worldwide.
Amanita phalloides
Angel of death
Amanita phalloides
Result from ingestion of food or feed that contains
mycotoxins.
MYCOTOXICOSIS
Variety of mycotoxins are produced by mushrooms
(e.g., Amanita species), and their ingestion results in a
dose-related disease called
mycetismus
Most potent, which is peptide elaborated by produced
primarily by Aspergillus flavus and Aspergillus
parasiticus- other species of aspergillus produce
aflatoxins as well
aflatoxin
Acute aflatoxicosis has been manifested in humans as
an
acute hepatitis
frequent contaminant of peanuts, corn, grains
and other foods
aflatoxin
most potent natural carcinogen
known and is the major aflatoxin produced by toxigenic
strains
Aflatoxin B1
toxic alkaloids produced by
the fungus Claviceps purpurea - growing on the fruiting
heads of rye.
Ergotoxicosis
structure common to all ergot alkaloids
Lysergic acid
What fungus caused Ergotoxicosis
Claviceps purpurea
Hardened masses of fungal tissue (sclerotia) that are
formed when the fungus invades the floret and replaces
the grain of wheat, barley, or rye
ERGOT ALKALOIDS
(scabby grain intoxication
Akakabibye
Toxic metabolites produced by fungi have been used by
primitive tribes for religious, magical and social
purposes.
PSYCHOTROPIC AGENTS
produced by the Psilocybe species
and other fungi.
hallucinogenic agents
2 types of Mycotic poisoning
- Mycetism
- Mycotoxicosis
