INDUSTRIAL APPLICABILITY
 [0236] As described above, the purple non-sulfur bacteria of the present invention has various effects of suppressing ulcer formation, suppressing inflammatory cell invasion, suppressing swelling of a mucosal epithelium, regenerating an epithelium, suppressing hepatic necrosis, accelerating swelling of liver cell, reducing amounts of IgE and histamine in a serum, suppressing Th2 cytokine secretion, ameliorating a Th1/Th2 imbalance, suppressing an allergic reaction, suppressing an autoimmune disease, enhancing stamina, anti-fatigue, and the like. The purple non-sulfur bacteria of the present invention can prevent and/or ameliorate at least one disease selected from the group consisting of inflammatory diseases, allergic diseases, and autoimmune diseases, can enhance stamina, and can suppress fatigue. The purple non-sulfur bacteria of the present invention has high safety, so that it can be administered for the purpose of preventing diseases, and also, it can be administered for a long term. Thus, according to the present invention, a preventive and/or ameliorative agent, a stamina enhancement agent, an anti-fatigue agent, a pharmaceutical, and food and drink, being useful in preventing and/or ameliorating at least one disease selected from the group consisting of inflammatory diseases, allergic diseases, and autoimmune diseases, enhancing stamina, and anti-fatigue and having high safety, can be provided, and application ranges thereof are not limited and wide.
