Intradermal immunotherapy with actinomycetales preparations as treatment for feline atopic syndrome: a randomized, placebo-controlled, double-blinded study.

The use of multiple intradermal injections of heat-killed GB shows promise as effective and well-tolerated treatment for FAS. Because of the low cost and the lack of adverse effects, GB could be a beneficial treatment option for FAS. A larger study is needed to confirm these data and to evaluate the immunological changes occurring in the treated cats.
