Does Real-Time RT-PCR for CSF Mark the Beginning of a Paradigm Shift in the Control of CSF?

摘要

When "one conceptual world view is replaced by another" we are talking about a paradigm shift. Based on new scientific data, Kuhn's concept of paradigm shifting will be used in this presentation to propagate the necessity of changes in the policy to control and eradicate Classical Swine Fever (CSF). The present CSF control strategy is more than 20 years old. Two fundamental changes have occurred which justify a new policy. In the first place there is no longer a rationale for the strict non-vaccination strategy. Culling of healthy pigs has become an ethical and animal welfare issue and is no longer tolerated. Secondly, significant advances in diagnosis and modern vaccines have been made (real-time RT-PCR, DIVA strategy). The foundations for new concepts to control CSF based on novel diagnostic tools and vaccines have been laid.
