T2 Rapid Test Kit is a rapid, one step test for the qualitative (or quantitative) detection of T2 in animal feed and grains
(wheat, wheat bran, corns, coconut, millet, flour). The total assay time takes 8 min.
What is T2 toxin?
T-2 toxin is one of the trichothecenes (TS) compounds produced by a variety of fungi, mainly Fusarium trichocarpa. It is widely distributed in nature. It is a common toxin that pollutes field crops and stockpiled grains, harmful to humans and livestock.
In a joint meeting of the United Nations Food and Agriculture Organization (FAQ) and the World Health Organization (WHO) in Geneva in 973, this type of toxin, like aflatoxin
, was regarded as the most dangerous source of food contamination in nature. After Vietnam used the "yellow rain" toxin (which contains T-2 toxin) in Southeast Asia, the harm of T-2 toxin to human health has aroused great concern of scientists from all over the world. More research has been carried out on the toxicology of toxins.
2. T2 Characteristics
The molecular weight of T-2 toxin
is 466.51, and the chemical name of the poison is 4,15-diacetoxy-8-(isovaleryloxy)-12,13-epoxytrichothecene-9-ene-3 -Alcohol, in which the oxygen ring and double bond are its active sites, and the opening of the oxygen ring or double bond reduction can reduce its toxicity. T-2 toxin is a white needle-like crystal, which is quite stable at room temperature. The toxicity is not reduced after being placed for 6-7 years or heated to 100-120℃ for 1 hour. T-2 toxin has an ester group, which is hydrolyzed to the corresponding alcohol after being treated with alkali.
There are few reports of T-2 toxin poisoning by inhalation through the respiratory tract. The main reason for poisoning is that oral poisoning T-2 toxin has a high absorption rate through the mucosa, and can directly destroy the capillaries of the mucosa and increase its permeability. The toxicity of T-2 toxin to different animals has certain species differences. Newborn or juvenile animals are more sensitive to toxins than adult animals.
3. T2 Toxicological effects
T-2 toxin mainly acts on tissues and organs with vigorous cell division, such as thymus, bone marrow, liver, spleen, lymph nodes, gonads and gastrointestinal mucosa, and inhibits the synthesis of protein and DNA in these organs. In addition, it was also found that the toxin can cause DNA single strand breaks in lymphocytes. T-2 toxin can also act on multiple sites of oxidative phosphorylation and cause mitochondrial respiratory depression.
T2 toxin hazards
Trichothecenes, a highly toxic mycotoxin
produced by Trichothecium spp or Fusarium spp. It can cause various symptoms of poisoning in humans or livestock, mainly vomiting, refusal to eat, gastrointestinal mucosal ulcers, inflammation, hemorrhagic lesions, and neurological symptoms. T-2 toxin is teratogenic and weakly carcinogenic. It mainly damages the animal's hematopoietic organs (inhibits the regenerative hematopoietic function of bone marrow and spleen), immune organs (reduces immune function), digestive system (causes hemorrhage and necrosis of the digestive tract), and nerves system and reproductive system, etc.
It is an epithelial necrosis factor that can cause necrosis and ulceration of the epithelium of the skin, oral cavity and upper digestive tract. It has an immunosuppressive effect on pigs, causing lymphopenia, decreased serum total protein levels, gastrointestinal bleeding, and degenerative changes in liver and kidneys. In addition, it can cause cell mutation and distortion.
1. T2 toxin in swine
The clinical symptoms of porcine T-2 toxin poisoning are mainly indigestion, loss of appetite, slow growth, lesions in the mouth and skin, vomiting, and immunosuppression.
2. T2 toxin in poultry
Poultry T-2 toxin poisoning showed decreased egg production rate, thin-shelled eggs, uneven feather production, oral ulcers, decreased appetite or even annihilation, dyskinesia, and decreased immunity. Studies have found that gavage of 10-20μg/chicks for a long period of time can show significant atrophy of immune organs such as spleen, thymus and bursa of Fabricius. Broilers after T-2 toxin poisoning are more susceptible to infection by Salmonella
and Newcastle disease
Studies have shown that when the T-2 toxin content in the feed reaches 8 mg/kg, the egg production of laying hens is significantly reduced. When the T-2 toxin content reaches 20 mg/kg and fed for 2 weeks, the egg production rate decreases by 20%, and thin-shelled eggs have increased significantly.
