December 17, 2009 - Mycotoxin intestinal absorption - specifically at the

effects of DON on the gastrointestinal tract - is the subject of one of the

latest videos on BIOMIN's Mycotoxin Channel on YouTube.

In this concise one-minute-plus clip, Dr. Isabelle Oswald of the French National

Institute of Agricultural Research (INRA) explains what happens in the

intestines of animals as a result of the mycotoxin DON. Also known as

deoxynivalenol or vomitoxin, DON is among the most commonly occurring of

Fusarium mycotoxins often associated illness in farm animals or humans.

The gastrointestinal tract is the first barrier that the mycotoxin DON

encounters in the animal's body. Once ingested, DON weakens the intestine

significantly, altering its protective barrier function and allowing more

contaminants to enter the lumen of the gastrointestinal tract. This produces a

deleterious effect on the animal.

From a weakened gastrointestinal tract, Dr. Oswald explains that bacteria are

then able to translocate themselves to the rest of the animal.

Dr. Oswald is the head of immuno-mycotoxicology at INRA, specializing in

research on the impact of mycotoxins on the immune system, particularly in pigs.

Besides the effects of DON, Dr. Oswald Oswald has also touched on the long-term

effects of mycotoxins on pigs, and ways to analyse the mycotoxin effect in the

gastrointestinal tract, on the Mycotoxin Channel.

The Mycotoxin Channel consists of webinars that address specific questions on

mycotoxin problems and mycotoxin management issues around the world. Topical

sections include analysis, mycotoxin risk management, mycotoxins in general and

symptoms.
