Comparison of results for intradermal testing between clinically normal horses and horses affected with recurrent airway obstruction.

Objective: To evaluate differences in response to ID injection of histamine, phytohemagglutinin (PHA), and Aspergillus organisms between clinically normal horses and horses with recurrent airway obstruction (RAO).

Animals: 5 healthy adult horses and 5 adult horses with RAO.

Procedure: Intradermal testing (IDT) was performed on the neck with 2 positive control substances (histamine and PHA) and a mixture comprising 5 Aspergillus species.

Evaluation of the precision of intradermal injection of control substances for intradermal testing in clinically normal horses.

Objective: To evaluate the precision of intradermal testing (IDT) in horses.

Animals: 12 healthy adult horses.

Procedure: IDT was performed on the neck of each horse by use of 2 positive control substances (histamine and phytohemagglutinin [PHA]) and a negative control substance.
