After this reaction, the future intake of mammal meat with the same alpha-gal causes an allergic reaction. Symptoms of the allergy reaction are caused by too many IgE antibodies attacking the allergen, in this case the alpha-gal. A traditional skin-prick allergy test for allergy to meat may give a false-negative answer. Blood tests for IgE response indicating alpha-gal allergy have not been approved by the U.S. Food and Drug Administration, and must usually be

This concept laid the foundation for the elaboration of a number of preventive measures and promoted the development of the environmental trend in parasitology (together with the works of parasitologist Valentin Dogel).

"Ehrlichia canis" is the pathogen of animals. Humans can become infected by "E. canis" and other species after tick exposure. German Shepherd Dogs are thought to be susceptible to a particularly severe form of the disease, other breeds generally have milder clinical signs. Cats can also be infected.

Ticks can transmit "B. burgdorferi" to humans, but humans are dead-end hosts, unlikely to continue the life cycle of the spirochete. Nymphs molt into adult ticks, which usually feed on larger mammals that are not able to support the survival of "B. burgdorferi".

While it is rare, it is possible for HGA to be transmitted human-to-human via a blood transfusion, in which case it is called Transfusion-Transmitted Anaplasmosis (TTA).

neg: Effects of global warming on human health More specifically, maximum temperature has been found to play the most influential variable in sustaining tick populations. Higher temperatures augment both hatching and developmental rates while hindering overall survival. Temperature is so important to overall survival that an average monthly minimum temperature of below -7 °C in the winter can prevent an area from maintaining established populations. The effect of climate on the tick life cycle is one of the more difficult projections to make in relation to climate and vector-borne disease. Unlike other vectors, tick life cycles span multiple seasons as they mature from larva to nymph to adult.

Coinfections complicate Lyme symptoms, especially diagnosis and treatment.

Larvae and nymphs, as well as adults are capable of causing very dramatic allergic reactions. Dramatic local redness ("erythema") and fluid swelling ("oedema") may develop within 2–3 hours of attachment of even one larva.
