In recent weeks, several cases of swine dysentery associated with B. hyodysenteriae or “B. hampsonii” have been reported in Quebec.
Many species of Brachsyspira have been identified in pigs: B. hyodysenteriae, B. innocens, B. pilosicoli, B. murdochii, B. intermedia, B. suanatina and “B. hampsonii’’
To date, however, only 4 species of Brachyspira have been formally recognized as pathogens in this species:
- B. hyodysenteriae, B. suanatina and “B. hampsonii’’ (clades I and II), responsible for mucohemorrhagic colitis. Note that B. suanatina has been reported only in Scandinavian countries.
- B. pilosicoli, responsible for “swine intestinal spirochetosis’’
The role of B. murdochii is not clear at the present time.
At Biovet, we are now able to detect B. hyodysenteriae and “B. hampsonii” by real-time PCR (RT-qPCR) directly from feces, the large intestine or its contents.
The availability of a PCR test for “B. hampsonii” avoids the need to proceed with sequencing of positive cases for Brachyspira spp, thereby reducing costs and response time.
Samples should be kept cool (4-8°C).
The price for both tests is $50.00 per sample.
The results are available 24 to 48 hours after receiving the samples.
