Influenza A virus (IAV) plays an important role in the porcine respiratory disease complex (PRDC). However, besides the co-infecting agents, the severity of infection and the course of disease is also influenced by the pig’s age, its health/immune status and the influenza strains involved. Since 2009, pandemic strains (H1N1pdm) have been detected in swine herds and have subsequently changed the dynamics on many farms.
For more than a decade Ceva has been supporting the diagnosis of influenza in Europe.
For detecting the virus, nasal swabs, oral fluids, bronchoalveolar lavage or lung tissue samples were taken either in herds with acute clinical signs linked to influenza or from those with unclear and persistent respiratory or reproductive symptoms. Each lab analysed the samples for IAV by PCR. Following subtyping of samples with a Ct-value <30* was performed by multiplex Real-Time PCR.
If you need support with influenza diagnosis, please contact your local Ceva Veterinary Service Team.

"The data represent the results on farm level"
*The Ct or threshold cycle value is the cycle number at which the fluorescence generated within a reaction crosses the fluorescence threshold, a fluorescent signal significantly above the background fluorescence. At the threshold cycle, a detectable amount of amplicon product has been generated during the early exponential phase of the reaction. The threshold cycle is inversely proportional to the original relative expression level of the gene of interest. Source: https://www.qiagen.com/
