Some recent studies suggest that the use of intranasal modified live virus vaccines against respiratory viruses may alter the microbial community and balance of opportunistic pathogens in the respiratory tract of cattle (1, 2). However, the implications of these changes in disease susceptibility are still unclear.

IBR is an acute, contagious respiratory disease of cattle caused by bovine herpesvirus type 1 (BHV-1), commonly affecting the respiratory tract and the reproductive system. It is highly contagious, resulting in rapid spread of respiratory disease among cattle in close confinement, particularly in feedlots and when groups of cattle are transported.

Infectious bovine rhinotracheitis (IBR) is a disease characterized by acute inflammation of the upper respiratory tract. BoHV-1 infection can also sporadically cause abortion in cattle. BoHV-1 infection affects animal health and productivity causing significant economic losses to …

What Is Infectious Bovine Rhinotracheitis? IBR is a highly contagious respiratory disease characterized by severe inflammation got the upper respiratory tract. If untreated, this virus can also cause abortions, conjunctivitis (watery eyes), …

2020年9月3日 · Infectious bovine rhinotracheitis (IBR) is a disease of cattle caused by infection with bovine herpesvirus 1 (BoHV-1). Clinical signs after infection with BoHV-1 can be observed in the respiratory, ocular, reproductive and nervous systems. Eight distinct herpesviruses are known to infect cattle, with BoHV-1 being the most common.

Infectious bovine rhinotracheitis (IBR) is a condition that can lead to a number of disorders affecting cattle’s respiratory systems (Wang et al., 2023). The disease is caused by bovine alphaherpesvirus type 1 (BoAHV-1) which belongs to the Herpesviridae family, subfamily Alphaherpesvirinae, and genus Varicellovirus (Kaddour et al., 2019).

2022年9月29日 · Infectious Bovine Rhinotracheitis (IBR) is a highly contagious, infectious respiratory disease that is caused by Bovine Herpesvirus-1 (BHV-1). It can affect young and older cattle. In addition to causing respiratory disease, this virus can cause conjunctivitis, abortions, encephalitis, and generalised systemic infections.

Infectious bovine rhinotracheitis (also known as IBR, BHV1, or “red nose”) is an infection of the upper airway and trachea caused by BHV1.

The infectious bovine rhinotracheitis (IBR) virus belongs to the group of herpes viruses. It causes in cattle a severe disease predominantly in the upper respiratory tract. Morbidity rate is 100 percent, mortality - depending on hygienic and other factors - ranges from 0-15 percent.
