Sampling

Virus detection requires the taking of nasal and throat swabs from several animals in an affected pen. Virus detection is possible only within the first few days post infection (p.i.). Antibody detection can be performed following the development of clinical symptoms, i.e. from around day 8 p.i. (see figure below).

Here too, samples from several animals should be tested in order to obtain a picture of the herd's infection status. Samples should be submitted to an appropriate laboratory.

IDT Biologika Animal Health provides support for serological and virological testing:

The following pictures illustrate the procedure for taking nasal swabs. For more information about IDT´s support of virological and serological testing, please contact either your area sales manager or your local technical service.
