Bovine herpesvirus 5 (BHV-5) Us9 is essential for BHV-5 neuropathogenesis.

Bovine herpesvirus 5 (BHV-5) is a neurovirulent alphaherpesvirus that causes fatal encephalitis in calves. In a rabbit model, the virus invades the central nervous system (CNS) anterogradely from the olfactory mucosa following intranasal infection. In addition to glycoproteins E and I (gE and gI, respectively), Us9 and its homologue in alphaherpesviruses are necessary for the viral anterograde ...

Neurovirulence of glycoprotein C(gC)-deleted bovine herpesvirus type-5 (BHV-5) and BHV-5 expressing BHV-1 gC in a rabbit seizure model.

Herpesvirus glycoprotein C (gC) is one of the major virus attachment proteins. Bovine herpesvirus type 1 (BHV-1) causes respiratory and genital diseases in cattle, whereas BHV-5 causes acute meningoencephalitis in calves. The gC gene sequence of these two viruses are substantially different. To determine the contribution of the BHV-5 glycoprotein gC (gC5) to the neuropathogenesis of BHV-5, we h...

The Us9 gene of bovine herpesvirus 1 (BHV-1) effectively complements a Us9-null strain of BHV-5 for anterograde transport, neurovirulence, and neuroinvasiveness in a rabbit model.

The alphaherpesvirus envelope protein Us9 is a type II viral membrane protein that is required for anterograde spread of bovine herpesvirus 5 (BHV-5) infection from the olfactory receptor neurons to the brain. In a rabbit seizure model, Us9-deleted BHV-5 failed to invade the central nervous system (CNS) following intranasal infection. However, when injected directly into the olfactory bulb, ret...

Spread of bovine herpesvirus type 5 (BHV-5) in the rabbit brain after intranasal inoculation.

Following intranasal inoculation of wild-type BHV-5 in rabbits, we studied the sequential transneuronal passage of the virus in the CNS by immunocytochemistry, histopathology, and virus isolation. At 4 and 6 days postinfection (d.p.i.), rabbits had no or mild neurological signs, and virus was isolated only from the olfactory bulbs. At 8 and 9 d.p.i., infected rabbits had severe neurological sig...
