How many people have been diagnosed with alpha-gal?

In 2009, there were 24 reported cases of alpha-gal syndrome; however, most recent estimates exceeded 5,000 cases and AGS was identified as the leading cause of anaphylaxis in a southeastern registry of patients (Pattanaik et al., 2018).

What is the most commonly reported tick borne disease in the United States?

Lyme disease, caused by Borrelia burgdorferi, is a potentially serious bacterial infection affecting both humans and animals. It is the most common tickborne disease reported in Minnesota and in the United States.

How long after tick bite does meat allergy start?

Symptoms commonly appear 2-6 hours after eating meat or dairy products, or after exposure to products containing alpha-gal (for example, gelatin-coated medications). AGS reactions can be different from person-to-person. They can range from mild to severe or even life-threatening.

Do all Lone Star ticks transmit alpha-gal?

Here’s what you need to know: Humans do not produce alpha-gal. Individuals bitten by the Lone Star tick can develop an allergy (IgE) antibody to alpha-gal (but not everyone does) Red meat (beef, pork, lamb, venison) contains alpha-gal.

Can you get lymes disease from a wood tick?

Ticks not known to transmit Lyme disease include Lone star ticks (Amblyomma americanum), the American dog tick (Dermacentor variabilis), the Rocky Mountain wood tick (Dermacentor andersoni), and the brown dog tick (Rhipicephalus sanguineus).

How long does a lone star tick have to be attached to transmit disease?

Even if a tick is attached, it must have taken a blood meal to transmit Lyme disease. At least 36 to 48 hours of feeding is typically required for a tick to have fed and then transmit the bacterium that causes Lyme disease. After this amount of time, the tick will be engorged (full of blood).

Is alpha-gal found in black-legged ticks?

† Alpha-gal has been found in the saliva of the Black-legged Tick (Ixodes scapularis) ( 10) and Amblyomma sculptum ( 14 ). As of yet, Black-legged Tick (Ixodes scapularis) have not been associated with AGS.

Can ticks induce alpha-gal syndrome (AGS)?

Alpha-gal -modified proteins have been found in the salivary glands of Hyalomma marginatum, Rhipicephalus bursa and cells of Rhipicephalus microplus ( 3), but we do not yet know if these species can induce AGS. It is likely that other species of ticks can also induce alpha-gal syndrome ( 10 ), but research is needed to demonstrate this.

What is alpha-gal syndrome (AGS)?

There is evidence that the alpha-gal molecule is found in the saliva of certain types of ticks. What is alpha-gal syndrome (AGS)? Alpha-gal syndrome (AGS) (also called alpha-gal allergy, red meat allergy, or tick bite meat allergy) is a serious, potentially life-threatening allergic reaction.

What is an alpha-gal allergy?

An alpha-gal allergy is an allergy to the alpha-gal sugar molecule. Allergic reactions typically occur after people eat meat from mammals that have alpha-gal or are exposed to products made from mammals.
