Insect sting allergy is the term commonly given to the allergic response of an animal in response to the bite or sting of an insect. [1] Typically, insects which generate allergic responses are either stinging insects ( wasps , bees , hornets and ants [ 2 ] ) or biting insects ( mosquitoes , ticks ).
It is generally safe and effective for allergic rhinitis, allergic conjunctivitis, allergic forms of asthma, and stinging insects. [6] The evidence also supports the use of sublingual immunotherapy against rhinitis and asthma, but it is less strong. [5] In this form the allergen is given under the tongue and people often prefer it to injections ...
Venom from stinging or biting insects such as Hymenoptera (ants, bees, and wasps) or Triatominae (kissing bugs) may cause anaphylaxis in susceptible people. [ 9 ] [ 33 ] [ 34 ] Previous reactions that are anything more than a local reaction around the site of the sting, are a risk factor for future anaphylaxis; [ 35 ] [ 36 ] however, half of ...
It is generally safe and effective for allergic rhinitis and conjunctivitis, allergic forms of asthma, and stinging insects. [138] To a lesser extent, the evidence also supports the use of sublingual immunotherapy for rhinitis and asthma. [137] For seasonal allergies the benefit is small. [139]
Another laboratory test is the blood test for IgE (immunoglobulin production), such as the radioallergosorbent test (RAST) or the more recent enzyme allergosorbent tests (EAST), implemented to detect high levels of allergen-specific IgE in response to particular allergens. Although blood tests are less accurate than the skin tests, they can be ...
Mosquito saliva contains >30 potentially allergenic proteins. More than 11 of these have been identified in the saliva of the Aedes egypti mosquito. Four such proteins, termed Aed a 1 (an apyrase), Aed 2 (Female-specific protein, D7), Aed 3 (an as yet undefined protein), and Aed a 4 (an α-glucosidase) have been purified as recombinant proteins.
The saliva of the arthropod may contain anticoagulants, as in insects and arachnids which feed from blood. Feeding bites may also contain anaesthetic , to prevent the bite from being felt. Feeding bites may also contain digestive enzymes , as in spiders ; spider bites have primarily evolved to paralyse and then digest prey.
A stinger (or sting) is a sharp organ found in various animals (typically insects and other arthropods) capable of injecting venom, usually by piercing the epidermis of another animal. An insect sting is complicated by its introduction of venom , although not all stings are venomous.
