Sporotrichosis (also known as "Rose gardener's disease") is a disease caused by the infection of the fungus ''Sporothrix schenckii''. This fungal disease usually affects the skin, although other rare forms can affect the lungs, joints, bones, and even the brain. Because roses can spread the disease, it is one of a few diseases referred to as ''rose-thorn'' or ''rose-gardeners' disease''. Because ''S. schenckii'' is naturally found in soil, hay, sphagnum moss, and plants, it usually affects farmers, gardeners, and agricultural workers.〔 It enters through small cuts and abrasions in the skin to cause the infection. In case of sporotrichosis affecting the lungs, the fungal spores enter through the respiratory pathways. Sporotrichosis can also be acquired from handling cats with the disease; it is an occupational hazard for veterinarians. Sporotrichosis progresses slowly - the first symptoms may appear 1 to 12 weeks (average 3 weeks) after the initial exposure to the fungus. Serious complications can also develop in patients who have a compromised immune system. ==Forms and symptoms== * ''Cutaneous or skin sporotrichosis'' :This is the most common form of this disease. Symptoms of this form include nodular lesions or bumps in the skin, at the point of entry and also along lymph nodes and vessels. The lesion starts off small and painless, and ranges in color from pink to purple. Left untreated, the lesion becomes larger and look similar to a boil and more lesions will appear, until a chronic ulcer develops. :Usually, cutaneous sporotrichosis lesions occur in the finger, hand, and arm. *''Pulmonary sporotrichosis'' :This rare form of the disease occur when ''S. schenckii'' spores are inhaled. Symptoms of pulmonary sporotrichosis include productive coughing, nodules and cavitations of the lungs, fibrosis, and swollen hilar lymph nodes. Patients with this form of sporotrichosis are susceptible to developing tuberculosis and pneumonia *''Disseminated sporotrichosis'' :When the infection spreads from the primary site to secondary sites in the body, the disease develops into a rare and critical form called disseminated sporotrichosis. The infection can spread to joints and bones (called ''osteoarticular sporotrichosis'') as well as the central nervous system and the brain (called ''sporotrichosis meningitis''). :The symptoms of disseminated sporotrichosis include weight loss, anorexia, and appearance of bony lesions. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「sporotrichosis」の詳細全文を読む スポンサード リンク
