Malassezia, Sarcoptes and Staphylococcus Phage Lysate (SPL®)


IgE positive results already being treated topically may benefit from immunotherapy treatment as well. IgG positive results are not applicable for immunotherapy.


A borderline or positive result will most likely require anti parasitic treatment to eliminate Sarcoptic mange.

Staphylococcus Phage Lysate (SPL®) therapy

Administration of SPL® therapy may be helpfuspl-quotel where there are high levels of anti-staphylococcal IgE and a diagnosis of atopic dermatitis has been made. It may also be useful in cases of recurrent pyoderma, whether or not this is accompanied by high levels of antibody. It is not indicated where IgG antibodies are only identified, unless this is accompanied by recurrent infection for which no cause is identified (i.e. in idiopathic recurrent pyoderma).
