IBR and IPV in cattle

IBR and IPV are different manifestations of infection with bovine herpesvirus 1, also called BoHV-1 or BHV-1. IBR primarily concerns the respiratory tract, while IPV affects the female genital tract. (MSD Veterinary Manual)

No signs does not necessarily mean no infection

The virus can remain latent, and infected animals may transmit infection without visible lesions. Transmission can occur through animal contact and infected semen. (MSD Veterinary Manual)

Herd status therefore cannot be judged simply by whether cows are coughing today. Control programmes can combine surveillance, biosecurity and appropriate vaccination. (MSD Veterinary Manual)

Signs that may prompt investigation

Respiratory disease can include fever, coughing, nasal and ocular discharge and reduced appetite. Severity varies, and secondary bacterial pneumonia can worsen the course. (MSD Veterinary Manual)

Genital infection can cause inflammatory lesions and erosions, and infection in pregnant cattle can result in abortion. This does not mean every respiratory illness or abortion is caused by BoHV-1. (MSD Veterinary Manual)

Testing and control

Diagnostic approaches include serology and detection of the virus, selected according to the clinical problem and herd history. Sample timing also matters. (MSD Veterinary Manual)

Vaccination planning must consider pregnancy and previous immunity because products differ in their properties and restrictions. Discuss the specific programme with the herd veterinarian rather than choosing by disease name alone. (MSD Veterinary Manual)

Prepare information on purchases, movements, reproductive events, vaccinations and tests. Record the affected groups and when the problem began.
