Alpha-gal Syndrome

PATHOGENS

  • While not a pathogen, alpha-gal syndrome represents the development of a food allergy to a sugar moiety (alpha-gal, technically galactose-α-1,3-galactose ) present in mammalian meat, usually red meats (e.g., pork, beef, lamb, goat, venison).
    • Associated with tick bites.
      • Amblyomma americanum (the Lone Star Tick) is most common in the U.S.
      • Other ticks may also be implicated, including Ixodes ricinus in Sweden.
