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 ...
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 .
Several studies have been undertaken of the toxic effects of aflatoxin M 1 in laboratory animals. However, in comparison to aflatoxin B 1, relatively little is known about the toxicity of aflatoxin M 1, primarily because of the difficulty in obtaining sufficient quantities of the pure compound necessary for extensive toxicity testing.

In humans, however, ivermectin has been found to be effective when used with a melanoma chemotherapy drug called dabrafenib. Ivermectin was also found to significantly reduce lung metastasis from ...
Aflatoxin B 1 is an aflatoxin produced by Aspergillus flavus and A. parasiticus.It is a very potent carcinogen with a TD 50 3.2 μg/kg/day in rats. [4] This carcinogenic potency varies across species with some, such as rats and monkeys, seemingly much more susceptible than others.
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]
