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.
Clinical signs and diagnosis
Calves normally suffer from a blood-flecked, thick, mucoid diarrhoea. They may be pyrexic, tachycardic, or 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 titers, culture on a selective medium, or histological examination. Specifically, C. fetus can be detected from cervicovaginal mucus using an agglutination test or ELISA.
