Parainfluenza virus type 3 (PIV3) is a RNA virus belonging to the Paramyxoviridae family which is extremely common in livestock throughout the world. PIV3 has been detected in both respiratory and digestive conditions, and it causes respiratory problems in young bovines. PIV3 is also considered as a cofactor in conditions associated with infection with certain bacteria (Mycoplasma bovis and Pasteurella hemolytica), and other viruses (including those that cause BVD and IBR). The symptoms of the disease are hyperthermia, coughing, ocular and nasal discharge, anorexia, dyspnoea and diarrhoea. PIV3 is also immunosuppressive and infected animals are predisposed to secondary infection. PIV3 is usually transmitted in nasal secretions and its transmission is favoured by animal transport (direct contact, poor ventilation and a stagnant atmosphere). To confirm PIV3 infection, serological testing is strongly recommended.
