Tick ​​that can cause lifelong allergy to red meat rears its head in America | Abroad

They don’t like low temperatures, but as soon as it gets warmer, they’re there: ticks. The small, spider-like parasites feed on blood. And that can be dangerous. Because when they bite a person and carry a bacterium, they can cause diseases. In our regions it is the Borrelia bacterium that, if the tick is not removed quickly enough, can cause Lyme disease.

There is another tick in the United States: the Amblyomma americanum, or the LoneStar tick. That is a tick that can transmit the alpha-bile syndrome, which the tick contracted from a mammal. It is a type of allergy to red meat, The Washington Post reports.


Humans do not have the carbohydrate alpha-gal in the body, but it is present in red meat. When someone is bitten by an infected tick, alpha-gal can enter the bloodstream. The body responds to this by making antibodies against alpha-gal. As a result, every time red meat is eaten, the body will consider it an attack and will react again.

The allergy is difficult to diagnose at first, because the body only reacts to the alpha-gal a few hours after eating red meat. The symptoms of the allergic reaction can then add up quickly: headache, itching, swelling, diarrhea and vomiting. Over time, these reactions can become increasingly fierce, to the extent that eating red meat becomes virtually impossible.

The Amblyomma americanum can be recognized by the white spot at the top of the shield, but the tick is not found in our country. Although the allergy can still be transmitted by the sheep tick, which occurs in Europe, which can also cause Lyme disease.
