Project description

Masticatory muscle myositis (MMM) refers to immune-mediated (autoantibody) inflammation of the masticatory muscles. The myofibers of the masticatory muscles are unique compared to other muscles in the body and therefore only the masticatory muscles are affected in MMM. Diagnosis is confirmed by measuring specific IgG-antibodies from the dog's blood sample.
