Abstract

This case series describes the diagnosis of allergic dermatitis and management with allergen-specific immunotherapy (ASIT) based on intradermal allergy testing (IDAT) and adjunctive medical therapy in six pteropid bats; five large flying foxes (Pteropus vampyrus); and one variable flying fox (Pteropus hypomelanus). The cases ranged from 2 to 15 yr of age at the time of presentation. Clinical signs varied between individuals and included moist ulcerative cutaneous lesions in nonhaired skin, blepharoconjunctivitis, alopecia, and pruritus. All bats underwent IDAT under general anesthesia, and reactive allergens included a mixture of grasses, trees, weeds, and biting insects. Three of the six cases (50%) had reformulation of the ASIT before control of clinical signs was seen, and two bats were treated with the addition of oclacitinib (Apoquel). Severe adverse effects were not identified; however, one bat had self-limiting swelling at the immunotherapy injection site. All six cases showed improvement of clinical signs and perceived comfort level, including in subsequent allergy seasons.
