Disease syndromes

Swine

In swine, infection with Brahcyspira pilosicoli causes a disease known porcine intestinal spirochaetosis [1]. Clinical signs associated with the disease include reduced productivity, hemorrhagic colitis and bloody mucoid diarrhea[1]. Stressors such as weaning and mixing predispose pigs to the disease and are the times when the disease occurs most frequently.

Poultry

In poultry, infection with Brachyspira pilosicoli causes a characteristic disease called avian intestinal spirochaetosis (AIS)[2]. Disease is associated with severe watery diarrhea and loss of productivity. The disease occurs most frequently in laying hens and breeding flocks[2]. It is unlikely to see AIS in broiler barns because the birds are typically slaughtered before they come in contact with the bacteria. In laying hens, AIS can result in decreased egg production, delayed onset of egg production and reduced egg quality, all causing economic impacts to the producer (reference).

Humans

Evidence of human intestinal spirochaetosis is limited. Risk of infection is higher for those who are immunocompromised.
