S309 Maedi-Visna Resistance


Maedi-Visna Virus (also known as Visna-Maedi Virus, Ovine lentivirus and Ovine Progressive Pneumonia) is an infectious disease that can cause both chronic pneumonia and encephalitis in sheep and goats. The virus has a long incubation time and high mortality rate, and no effective vaccine or treatment against it currently exists. However, some sheep have been found to have genetic resistance against the disease, which can dramatically improve survival rates. The test offered here is for a variant of the gene TMEM154. Sheep homozygous for this variant, which can found among all breeds, have been demonstrated to be less susceptible to infection.

Turn Around Time

The turn-around-time of a test depends to a large extent on the logistics of sample transportation to the laboratory. After receiving the sample at the test location, you can normally expect the result within 10 working days. A longer delivery time applies to tests carried out by a Partner Lab.
