What should I do to make my PRRSV control program successful?
The end goal of any control program should always be to stop the virus from circulating in the sows in order to create a flow of negative growing pigs.

How can I efficiently monitor PRRSV circulation on the farm?
Thinking about successful monitoring, one should keep in mind the objectives, the production phase, and the type of animal to be tested.

15-Mar-2021Carles VilaltaHi Tamara,
you raise a great point. We have had some experience using oral swabs from piglets and comparing them with serum, sensitivity was pretty good specially for those piglets that ahave higher viremia. They are quicker to take than serum samples and any user in a farm can do it as it does not require training. We thought a lot about what you were saying and we still have that research pending. But if we can find the right amount of pooling without compromising the sensitivity it would be a very interesting way of sampling to have in the tool box.
Cheers!

PRRS - Why can't I achieve long-term stability on my farm?
Its high survivability in the environment, a long infective period, limited cross-protection, strains with different pathogenicity, and lateral infections make stabilization difficult.
