Question

Sapienic acid inhibits microbial growth in this organ, where it’s produced by Propionibacteria-mediated degradation of triglycerides. Increased porphyrin production in this organ due to Vitamin B12 supplementation is associated with a condition sometimes treated with tetracyclines. KOH (“k-o-h”) dissolves cells from this organ to yield a “spaghetti and meatballs” appearance in a positive test for Malassezia. Filaggrin mutations make this organ more susceptible to colonization by reducing the integrity of (*) corneocytes. Comedones (10[2])(“kah-muh-DOH-neez”) form in this non-pancreatic organ, whose resident dendritic cells are Langerhans cells. (-5[1])Along with mucous membranes, (-5[1])Staph aureus naturally colonizes this organ, where it processes (-5[1])apocrine gland secretions and sebum. (-5[1])For 10 points, name this organ (10[1])where microbes and hyperkeratinization cause acne. (10[1])■END■ (10[3]0[1])

ANSWER: skin [prompt on dermis or epidermis by asking “can you be less specific?”] (Propionibacteria also cause the increased porphyrin production associated with acne.)
