9EHV 1 is prevalent in horses [blank_start]worldwide[blank_end] and being a typical [blank_start]alphaherpesvirus[blank_end] it produces a latency in neurones. Recurrence and recrudescence commonly occur throughout life with the potential to infect other animals. [blank_start]Neurological[blank_end] disease appears to be related to the [blank_start]ability[blank_end] to produce a high titre viraemia in circulating cells.

10EAND pathogenesis is as follows:
A febrile illness followed by macrophage associated transport to the [blank_start]CNS[blank_end]. Vascular infection is central to [blank_start]lesions[blank_end] in the brain and spinal cord. There is [blank_start]vasculitis[blank_end] and [blank_start]thrombosis[blank_end] with resultant ischaemia, [blank_start]myelomalacia[blank_end] and in most cases [blank_start]haemorrhage[blank_end].- ACNS
- Blesions
- Cvasculitis
- Dthrombosis
- Emyelomalacia
- Fhaemorrhage
11only a live attenuated vaccine can be used for EHV 1 and EHV 4
- ATrue
- BFalse
12EHV 2 and EHV 5 are...
- Aalphaherpesviruses
- Bbetaherpesviruses
- Cgammaherpesviruses
13EHV 2 has been associated with keratitis and keratoconjunctivitis in infected horses.
- ATrue
- BFalse
14EHV 5 alone, or in associated with EHV 2 or AHV 5 can be linked with characteristic interstitial lung fibrosis now identified as equine multinodular pulmonary fibrosis.
- ATrue
- BFalse
15the usual mode of transmission for equine herpesvirus 3 is [blank_start]venereal[blank_end].
- Avenereal
16In canine herpesvirus the pups can be infected in utero or as they are being born.
- ATrue
- BFalse
17signs of canine herpesvirus include...
- Avocalisation
- Banorexia
- Cdyspnoea

- Icoughing
- Jerythema
18Feline viral rhinotracheitis arises from [blank_start]felid herpesvirus 1[blank_end] which is a type of [blank_start]alphaherpesvirus[blank_end] and [blank_start]causes upper respiratory tract[blank_end] disease, conjunctivitis, ulcerative keratitis, pneumonia and abortion.
- Afelid herpesvirus 1
- Bcanine herpesvirus 1
- Cfelid herpesvirus 2
- Dalphaherpesvirus
- Ebetaherpesvirus

19Infectious laryngoracheitis virus is a type of [blank_start]alphaherpesvirus[blank_end] and known as [blank_start]gallid herpesvirus 1[blank_end].
- Aalphaherpesvirus
- Bbetaherpesvirus
- Cgammaherpesvirus
- Dgallid herpesvirus 1
- Egallid herpesvirus 2
20Transmission of Infectious Laryngotracheitis occurs via the [blank_start]respiratory tract[blank_end]. Following the acute infection the virus produces a latent infection in [blank_start]neurones[blank_end]. Transmission can occur throughout life and between flocks can occur via [blank_start]aerosols[blank_end] and [blank_start]fomites[blank_end]. Live [blank_start]viral[blank_end] vaccines are used they are [blank_start]attenuated[blank_end] viruses and are applied by [blank_start]spray[blank_end] or [blank_start]eyedrop[blank_end].
- Arespiratory tract
- Bneurones
- Caerosols
- Dfomites
- Eviral
- Fattenuated
- Gspray
- Heyedrop
21Marek's disease is a lymphoproliferative disease with infiltration of nerves and visceral organs, the acute infection is responsible for the lysis of both B cells and T cells.
