The accumulation of sphinganine and sphingosine is a primary cause of the toxicity of fumonisin B 1 [13] Sphinganine and sphingosine are cytotoxic, and have growth inhibitory effects. Also, these sphingoid bases induce apoptosis. Increased apoptosis seems to play an important role in the toxic effects including tumor induction. [8]
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]
