Amblyomma americanum, a vector for the allergy<unk> es develop after a person has been bitten by the lone star tick in the United States, the European castor bean tick, the paralysis tick or Ixodes (Endopalpiger) australiensis in Australia, Haemaphysalis longicornis in Japan, or a currently unknown tick in South Africa, possibly Amblyomma hebraeum.<unk> -gal is not naturally present in apes, Old World monkeys, or humans, but is in all other mammals. If a tick feeds on another mammal, the<unk> -gal remains in its alimentary tract. The tick then injects the<unk> -gal into a person's skin, which causes the immune system to release a flood of IgE antibodies to fight the foreign carbohydrate. Researchers still do not know which specific component of tick saliva causes the reaction. A 2012 preliminary study found unexpectedly high rates of<unk>  in the Western and North Central parts of the United States. This suggests that unknown tick species may spread the allergy. The study even found<unk>  cases in Hawaii, where no ticks identified with the allergies live. Human factors were suggested, but no specific examples were provided.<unk> -gal is present in the anticancer drug cetuximab, as well as the intravenous fluid replacements Gelofusine and Haemaccel. Blood thinners derived from porcine intestine and replacement heart valves derived from porcine tissue may also contain<unk> -gal. At least one instance of a man with an<unk>  going into anaphylaxis after receiving a heart valve transplant has been reported. Some researchers have suggested that the<unk> -gal in pig's tissue that surgeons use for xenografts might contribute to organ rejection.
