Cell-wall-deficient bacteria: a major etiological factor for psoriasis?

Background: Psoriasis is a common inflammatory skin disease, yet knowledge of the factors that may induce, trigger, or exacerbate psoriasis is not fully delineated.

In the present study we assessed the prevalence of CWDB infection in patients with psoriasis.
