D433 - Bovine Parainfluenza virus

Parainfluenza-3 virus (PI-3) is an RNA virus classified in the paramyxovirus family. Infections caused by PI-3 are common in cattle. Although Parainfluenza-3 is capable of causing disease, it is usually associated with mild to subclinical infections. The most important role of PI-3 is to serve as an initiator that can lead to the development of secondary bacterial pneumonia. Clinical signs include pyrexia, cough, serous nasal and lacrimal discharge, increased respiratory rate, and increased breath sounds. The severity of signs worsen with the onset of bacterial pneumonia.

PCR-based diagnostic tests enable accurate and timely detection of Parainfluenza-3 virus. DNA based tests specifically target the genetic material of Parainfluenza-3 virus ensuring sensitive and specific diagnosis. Positive DNA test result confirms actual infection.
