Summer eczema, insect bite hypersensitivity in horses


Insect bite hypersensitivity: Insect bite hypersensitivity (IBH) or summer eczema (SE) is a dermatitis of horses, caused by IgE mediated hypersensitivity reaction, to Culicoides spp. (biting midges) not indigenous to Iceland (Schaffartzik et al., 2012). All breeds of horses can be affected, but Icelandic horses born in Iceland and exported to the continent are more strongly affected than most other breeds (Bjornsdottir et al., 2006, Torsteinsdóttir 2018). Since the year 2000 there has been an ongoing collaborative Summer Eczema project between Keldur and the University of Berne, Switzerland.

The aim of the project is to find and characterize the allergens causing IBH and analyse the immune response that leads to the disease and the final aim is development of immunotherapy against insect bite hypersensitivity.
