No swine dysentery? Challenges that mild strains of Brachyspira hyodysenteriae pose to the industry

What happens if the agent that causes swine dysentery is detected, but there is no disease? This is how can it be diagnosed and the consequences to the herd.

Figure 1. Scatter plot showing the associations between the microbiome composition of pigs during early life (0-7 days), immediately pre-weaning (21 days), and after weaning (100 days). The largest shift is observed between pre-weaning and post-weaning samples. Alpha diversity is at its peak after weaning (shown as “microbiome diversity”).

Figure 1 – Hypothetical diagram depicting the microbiota response to an insult. 1) Healthy individuals have a normal degree of microbiota variation, which does not lead to disease (this is termed eubiosis, 2) A perturbation (e.g. heat stress) may lead to microbiota instability, causing disease. 3) Resilient microbiota will return to a state similar to that pre-perturbation, where there is no disease. 4) Microbiotas that are not resilient will not “bounce back”, thus suffering dysbiosis and a prolonged state of disease.

Figure 1. Estimated relative proportion of different microorganisms in the swine gut microbiome. While bacteria correspond to the vast majority of the microbes in the swine gut, other microorganisms play an important role in the complex network that is the gut-microbiota crosstalk.

31-May-2022L.VadopalasHello everyone,
here is our reasearch about it:
https://doi.org/10.3389/fvets.2020.528990
We think that it is very useful tool to get a better pig health and production status at the farm. There is possible modulate microbiota.
