Campylobacteriosis is an infection by the ''Campylobacter'' bacterium,〔(cdc.gov ) Centers for disease Control and Prevention〕 most commonly ''C. jejuni''. It is among the most common bacterial infections of humans, often a foodborne illness. It produces an inflammatory, sometimes bloody, diarrhea or dysentery syndrome, mostly including cramps, fever and pain. ==Cause== (詳細はGram-negative rods). The disease is usually caused by ''C. jejuni'', a spiral and comma shaped bacterium normally found in cattle, swine, and birds, where it is nonpathogenic, but the illness can also be caused by ''C. coli'' (also found in cattle, swine, and birds), ''C. upsaliensis'' (found in cats and dogs) and ''C. lari'' (present in seabirds in particular). One effect of campylobacteriosis is tissue injury in the gut. The sites of tissue injury include the jejunum, the ileum, and the colon. ''C jejuni'' appears to achieve this by invading and destroying epithelial cells. ''C. jejuni'' can also cause a latent autoimmune effect on the nerves of the legs, which is usually seen several weeks after a surgical procedure of the abdomen. The effect is known as an acute idiopathic demyelinating polyneuropathy (AIDP), i.e. Guillain–Barré syndrome, in which one sees symptoms of ascending paralysis, dysaesthesias usually below the waist, and, in the later stages, respiratory failure. Some strains of ''C jejuni'' produce a cholera-like enterotoxin, which is important in the watery diarrhea observed in infections. The organism produces diffuse, bloody, edematous, and exudative enteritis. In a small number of cases, the infection may be associated with hemolytic uremic syndrome and thrombotic thrombocytopenic purpura through a poorly understood mechanism. 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「Campylobacteriosis」の詳細全文を読む スポンサード リンク
