New observations on the epidemiology and pathogenesis of sporotrichosis

Abstract

Five uncommon cases of skin sporotrichosis are presented, including a small family outbreak with interesting epidemiological findings and two patients treated with corticosteroids; we attributed the severity of the lesions to the steroids. Mice were used to confirm our hypothesis on the pathogenesis. The pathological findings in case of sporotrichosis in a dog are presented. A group of 359 pulmonary patients was tested with two different antigens of Sporotrichum schenkii.
