Gastrointestinal campylobacteriosis is caused by ''Campylobacter jejuni'' or ''Campylobacter coli''. Although it is a commensal in the gastrointestinal tract of many species, it can cause diarrhea - mainly in young animals. It is most commonly seen in cattle, but may also infect many other species, including humans. ''Campylobacter'' is spread horizontally via the fecal-oral route.〔Campylobacteriosis - Cattle, reviewed and published by Wikivet at http://en.wikivet.net/Campylobacteriosis_-_Cattle, accessed 24/08/2011. 〕 ''Campylobacter fetus'' can also cause venereal disease and abortion in cattle.〔http://www.oie.int/fileadmin/Home/eng/Health_standards/tahm/2.04.05_BGC.pdf〕 ==Clinical signs and diagnosis== Calves normally suffer from a blood-flecked, thick, mucoid diarrhoea. They may be pyrexic, tachycardic, tachypneic and suffer weight loss. Adult cattle may show reproductive signs such as anoestrus, irregular oestrus patterns, agalactia, abortion and infertility. Campylobacter infection can be confirmed by rising antibody titres, culture on a selective medium or histological examination. Specifically, ''C. fetus'' can be detected from cervicovaginal mucus using an agglutination test or ELISA. 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「Bovine Campylobacteriosis」の詳細全文を読む スポンサード リンク
