No animal species is known to be immune to the acute toxic effects of aflatoxins. Adult humans have a high tolerance for aflatoxin exposure and rarely succumb to acute aflatoxicosis, [31] but children are particularly affected, and their exposure can lead to stunted growth and delayed development, in addition to all the symptoms mentioned below ...
Treatment of human liver cells with aflatoxin B 1 at doses that ranged from 3–5 μmol/L resulted in the formation of aflatoxin B 1-DNA adducts, 8-hydroxyguanine lesions and DNA damage. [41] Carcinogenicity The carcinogenicity of aflatoxin B 1, which is characterized by the development of liver cell carcinoma, has been reported in rat studies ...
A. parasiticus produces aflatoxins B1, B2, G1, and G2, named for the colours emitted under UV light on thin-layer chromatography plates—either blue and green. The numbers refer to the type of compound with 1 being major and 2 being minor. [3] These aflatoxins are carcinogenic mycotoxins which have detrimental effects to humans and livestock. [4]
Aflatoxin B 1, the most toxic, is a potent carcinogen and has been directly correlated to adverse health effects, such as liver cancer, in many animal species. [11] Aflatoxins are largely associated with commodities produced in the tropics and subtropics, such as cotton, peanuts, spices, pistachios, and maize.
The effect of aflatoxin M 1 was much weaker than aflatoxin B 1 in producing liver cancer. The limited animal studies carried out to determine toxicity of aflatoxin M 1. Aflatoxin M 1 has toxic and carcinogenic properties. The toxicity of aflatoxin M 1 in ducklings and rats seems to be slightly less than that of aflatoxin B 1.
Sterigmatocystin is a polyketide mycotoxin produced by certain species of Aspergillus.The toxin is naturally found in some cheeses.. Sterigmatocystin is a toxic metabolite structurally closely related to the aflatoxins as it is the penultimate precursor of aflatoxins B1 and G1. [1]
Bird flu is a scary illness with a high mortality rate. But so far, infections in the U.S. have been relatively mild—until now. A patient in Louisiana has been hospitalized with a severe case of ...
Adverse respiratory health effects are associated with occupancy in buildings with moisture and mold damage. [9] Infants in homes with mold have a much greater risk of developing asthma and allergic rhinitis. [10] [11] Infants may develop respiratory symptoms due to exposure to a specific type of fungal mold, called Penicillium. Signs that an ...
