Preliminary skin tests of tilapia, a teleost, sensitized with heat-killed, freeze-dried Mycobacterium tuberculosis failed to demonstrate an obvious and measurable mammalian or avian type of delayed hypersensitivity
A diagnosis of a type IV delayed hypersensitivity
reaction was made.
In addition, Pincus and Flick demonstrated the initial development of delayed hypersensitivity
, an index of cell-mediated immunity, as early as 2 days after smallpox vaccination (15).
3) Type IV latex allergies represent a delayed hypersensitivity
to one or more of the 300-plus chemicals used to manufacture latex and cause allergic contact dermatitis within 48 to 96 hours of exposure.
Summer Seasonal Recurrent Dermatitis (commonly known as "Sweet Itch") is a delayed hypersensitivity
to insect bites that results in an over-vigorous response by the horse's immune system.
After extravasation of the intravenous hirudin site, the patient developed a delayed hypersensitivity
reaction that histologically showed an epithelioid granulomatous infiltrate.
- type four: This sensitisation is caused by an allergy to the accelerating agents used in manufacturing latex.
Since tuber-culosis triggers a reaction called delayed hypersensitivity
in the immune system, the pair suggests that a vaccine designed to elicit this response might prove effective in fighting allergy and asthma in children.
