Infectious Bovine Rhinotracheitis aetiology

Alphaherpesvirinae: BHV-1 and BHV-5 (bovine herpesvirus)

Infectious Bovine Rhinotracheitis Main symptoms? + importance

Abortion in cows, Encephalitis in calves under 5 months, Respiratory symptoms

NOTIFIABLE

Bovine Herpesmammilitis? the occurence (continents) and the aetiology!

mainly in Africa, Australia and USA, rare in Europe

Alphaherpesvirinae: BHV-2

Malignant Catarrhal Fever Aetiology and occurence

Gammaherpesvirinae: Ovine Herpesvirus-2 (OHV 2), Alcephaline Herpesvirus-1 (AIHV-1)
in Africa: Wilderbeest associated malignant catarrhal fever, outside of africa sheep associated malignant catarrhal fever

Aujezkys disease - Which animals does it effect and what is the causative agent? + Importance

Swine is the reservoir, but Mammal and bird species also susceptible: mainly lethal encephalitis; cattle, sheep, horse, carnivores
SuHV-1 Suid Herpesvirus-1 -> antigenic relationship with BHV-1

NOTIFIABLE DISEASE

Inclusion Body Rhinitis of Swine - aetiology and whats its importance?

Suid Herpesvirus - 2 : SHV 2 Betaherpesvirinae
it is very rare that it causes clinical signs, it has no economic significance however in piglets under 3 weeks it can reach up to 25% mortality

Equine Rhinopneumonitis - Aetiology and importance?

Virus: Alphaherpesvirinae, Varicellovirus,
Equid Herpesvirus 1: Respiratory disease, abortion, CNS
Equid Herpesvirus 4: respiratory adaptation, (abortion)

Notifiable Disease!!

List of Herpesvirus Families and their mechanism of action

Alphaherpesvirus: replicate and spead rapidly, destroying host cells and establishing latent infections
Betaherpesvirus: replicate and spread slowly, causing cells to enlarge (Cytomegalovirus) - latent in secretory glands and lymphoreticular cells
Gammaherpesvirus: infect T or B Lymphocytes, latent infection in these cells

What is typical for herpesvirus in microscopic exam?

Intranuclear Inclusion Bodies (they replicate in the nucleus)

Coital Exanthema of Horses - Aetiology

Equid Herpesvirus 3 - Alphaherpesvirinae

Causative Agents of Further Herpes viral diseases of Horses + signs

EHV-2 and EHV-5 infection of Horses -> Gammaherpesvirinae widespread, fever, mild resp signs keratoconjuctivity rh. equi colonisation on mucosa - pneumonia 2 -> keratoconjunctivitis + respiratory disease in young foals the symptoms are often unnoticed no symptoms in adult animals EHV 5 may play a role in the equine multinodular pulmonary fibrosis

Canine Herpesviral Disease? causative agent

Canid Herpesvirus 1 (CaHV 1) Alphaherpesvirinae

Key points of Herpesvirus

Key points Enveloped DNAviruses with icosahedral symmetry Replicate in the nucleus Labile in the environment Three subfamilies of veterinary importance: Alphaherpesvirinae, Betaherpesvirinae, Gammaherpesvirinae Cause diseases of the respiratory, reproductive and nervous systems; may cause cell transformation in some species Latency is a common outcome of infection with these viruses

Papillomavirus Key Points

Key points - Non-enveloped, double-stranded DNA viruses - Icosahedral symmetry Contains one genus, Papillomavirus: -Have not been cultured in vitro --Cause papillomas and fibropapillomas in domestic animals -Malignant transformation of alimentary and urinary tract papillomas may occur in cattle ingesting bracken fern -Bovine papillomas type 1 and 2 are aetiologically involved in equine sarcoids

Parvovirus Key points

Key points Small, non-enveloped, single-stranded DNA viruses - Icosahedral symmetry Replicate in the nucleus, form intranuclear inclusion bodies Require rapidly-dividing cells for replication Stable in the environment Resistant to heat, solvents, disinfectants and pH changes Genus Parvovirus: -Many have haemagglutinating activity -Shed in large numbers in faeces -Enteric and systemic diseases in dogs and cats -Reproductive failure, SMEDI syndrome, in pigs

Adenovirus Key Points

Key points Non-enveloped, double-stranded DNA viruses, Icosahedral symmetry Replicate in nuclei, forming intranuclear inclusion bodies Moderately stable in the environment Two genera: -Aviadenovirus, avian adenoviruses -Mastadenovirus, mammalian adenoviruses Systemic and Respiratory diseases in dogs Systemic diseases in Poultry

Circovirus Key Points

Small, non-enveloped single-stranded DNA viruses with icosahedral symmetry Replicate in the nucleus of dividing cells Stable in the environment Circoviruses cause infections in chickens, pigs and plants
