Because mycotoxins weaken the receiving host, they may improve the environment for further fungal proliferation. The production of toxins depends on the surrounding intrinsic and extrinsic environments and these substances vary greatly in their toxicity, depending on the organism infected and its susceptibility, metabolism, and defense mechanisms.
Mycotoxicology is the branch of mycology that focuses on analyzing and studying the toxins produced by fungi, known as mycotoxins. [1] In the food industry it is important to adopt measures that keep mycotoxin levels as low as practicable, especially those that are heat-stable.
T-2 mycotoxin is a trichothecene mycotoxin. It is a naturally occurring mold byproduct of Fusarium spp. fungus which is toxic to humans and other animals. The clinical condition it causes is alimentary toxic aleukia and a host of symptoms related to organs as diverse as the skin, airway, and stomach.
Citrinin is a mycotoxin which is often found in food. It is a secondary metabolite produced by fungi that contaminates long-stored food and it can cause a variety of toxic effects, including kidney, liver and cell damage. Citrinin is mainly found in stored grains, but sometimes also in fruits and other plant products.
The trichothecene mycotoxins are toxic to humans, other mammals, birds, fish, a variety of invertebrates, plants, and eukaryotic cells. [21] The specific toxicity varies depending on the particular toxin and animal species, however the route of administration plays a significantly higher role in determining lethality.
Alimentary toxic aleukia is a mycotoxin-induced condition characterized by nausea, vomiting, diarrhea, leukopenia (aleukia), hemorrhaging, skin inflammation, and sometimes death. [1] Alimentary toxic aleukia almost always refers to the human condition associated with presence of T-2 Toxin. [1]
The toxins, named mycotoxins, deter other organisms from consuming the food the fungi colonise. As with bacterial toxins, there is a wide array of fungal toxins. Arguably one of the more dangerous mycotoxins is aflatoxin produced by certain species of the genus Aspergillus (notably A. flavus). If ingested repeatedly, this toxin can cause ...
The toxins used as defense in species among the poison dart frog can also be used for medicinal purposes; Some of the more well known types of biotoxins include: Cyanotoxins, produced by cyanobacteria; Dinotoxins, produced by dinoflagellates; Necrotoxins cause necrosis (i.e., death) in the cells they encounter.
