Rickettsial Genesis to Sarcoidosis in Denmark

One study has suggested a connection between an infection with Rickettsia species and sarcoidosis finding molecular evidence of rickettsial deoxyribonucleic acid (DNA) in two patients. Another study found no antibodies in twenty Swedish patients with sarcoidosis. This study will further enhance the subject by three different approaches in Danish patients. The purpose of this study is to find serological and molecular evidence of an infection with Rickettsia species in Danish patients with sarcoidosis.
