spirochaetosis

Balfour's most notable work during this period was on spirochaetosis.

It causes intestinal spirochaetosis in pigs, but its has also been isolated from dogs, birds and mice.

B. pilosicoli is the cause of porcine intestinal spirochaetosis.

This method is easily misdiagnosed, because pulmonary infections look like tuberculosis, pneumonia, or spirochaetosis.

With Salimbeni, he conducted a detailed study of avian spirochaetosis, providing a description on its mode of transmission.

With Marchoux, he identified Argas persicus as the vector of avian spirochaetosis.

Porcine intestinal spirochaetosis is a notifiable pig disease caused by the bacterium Brachyspira pilosicoli.

The disease is widespread in pig-rearing countries and may be referred to as PIS, spirochaetal diarrhoea and porcine colonic spirochaetosis.

B. pilosicoli can infect humans leading to human intestinal spirochaetosis, however most cases of HIS are caused by B. aalborgi, so its clinical relevance remains unclear.

The mites can also affect the health of the birds indirectly, as they may serve as vectors for diseases such as Salmonellosis, avian spirochaetosis and Erysipelothrix rhusiopathiae.

B. hyodysenteriae and B. pilosicoli are the classic Brachyspira gastrointestinal pathogens leading to diarrheal disease in growing pigs worldwide, causing the so-called swine dysentery, typhlocolitis or porcine intestinal spirochaetosis, which contributes to major "production losses" in agrobusiness.
