  • Title: DNA of bovine herpesvirus type 1 in the trigeminal ganglia of latently infected calves.
    Author: Ackermann M, Peterhans E, Wyler R.
    Journal: Am J Vet Res; 1982 Jan; 43(1):36-40. PubMed ID: 6283952.
    Abstract:
    Twelve calves infected with bovine herpesvirus type 1 (BHV-1) were killed when in a latent state of infection. Latency was verified 30 days after virus inoculation of the calves by seroconversion, absence of virus shedding, and in 2 calves, by recrudescence of the infection after they were treated with dexamethasone. By in situ hybridization techniques and autoradiography, DNA of BHV-1 was detected in 13 of 23 trigeminal ganglia of latently infected calves. Viral DNA was restricted to the nucleus of nerve cells. Single neurons harboring BHV-1 DNA were observed in 4.9% of the sections (n = 325) of the trigeminal ganglia. The results obtained correspond to those known from herpes simplex virus infections in mice. The implications for the virus-host relationship are discussed.
