Bovine Alphaherpesvirus 5
''Bovine alphaherpesvirus 5'' (BoHV-5) is a virus species of the genus ''Varicellovirus'' and subfamily ''Alphaherpesvirinae''. It causes meningoencephalitis and bovine respiratory disease, respiratory disease in cattle and sheep. As with all herpes viruses latent infection can occur, with recrudescence at times of stressed and/or immunosuppression. Sites of latency include the CNS and mucosae of the nose and trachea. The disease has been documented in South America, the United States, Australia, Germany and Hungary. Caused by: ''BHV-5 – Bovine Encephalitis Virus – Bovine Encephalitis Herpesvirus'' Disease is most common in calves up to ten months of age. Clinical signs and diagnosis Signs of respiratory disease include tachycardia and tachypnea with pyrexia, dyspnea, mucoid nasal discharge, hypersalivation and abnormal lung sounds. Systemic signs such as lethargy and Anorexia (symptom), anorexia are seen. Neurological signs are normally acute. These signs include opisth ...

Equid Alphaherpesvirus 9
''Equine alphaherpesvirus 9'' (EHV-9) is a species of virus in the genus ''Varicellovirus'', subfamily '' Alphaherpesvirinae'', family '' Herpesviridae'', and order '' Herpesvirales''. It was first isolated from a case of epizootic encephalitis in a herd of Thomson's gazelle (''Gazella thomsoni'') in 1993. Fatal encephalitis was reported from Thomson's gazelle, giraffe, and polar bear in natural infections. The virus was reported in an aborted Persian onager and a polar bear The polar bear (''Ursus maritimus'') is a hypercarnivorous bear whose native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is the largest extant bear specie .... References External links * Varicelloviruses Animal viral diseases {{Veterinary-med-stub ...

Caprine Alphaherpesvirus 1
''Caprine alphaherpesvirus 1'' (CpHV-1) is a species of virus known to infect goats worldwide. It has been shown to produce systemic and respiratory symptoms in kids and to cause abortions in adult goats. The virus is in the genus ''Varicellovirus ''Varicellovirus'' (var′i-sel′ō-vi′rŭs) is a genus of viruses belonging to subfamily ''Alphaherpesvirinae'', a member of family ''Herpesviridae''.

It is less studied than some of the other ruminant viruses in the genus ''Varicellovirus'' including '' Bovine alphaherpesvirus 1'' (BoHV-1), and research conflicts about its level of species specificity and its ability to cause bovine infection and illness. Like many other members of its genus, CpHV-1 has been shown to replicate in the respiratory tract and to cause latent infections. The ...

Cercopithecine Alphaherpesvirus 9
''Cercopithecine alphaherpesvirus 9'' (CeHV-9) is a species of virus in the genus ''Varicellovirus'', subfamily '' Alphaherpesvirinae'', family '' Herpesviridae'', and order '' Herpesvirales''. Pathology ''Cercopithecine alphaherpesvirus 9'' infects primates and shares clinical, pathological, immunological, and virological features with varicella-zoster virus infection of humans. Monkeys that had been inoculated intratracheally with the virus developed diffuse varicella 10 to 12 days later. Monkeys that were caged with each of the intratracheally infected monkeys developed a mild rash two weeks later, hence providing evidence of airborne transmission Airborne or aerosol transmission is transmission of an infectious disease through small particles suspended in the air. Infectious diseases capable of airborne transmission include many of considerable importance both in human and veterinary .... References External links * Varicelloviruses {{Virus-stub ...

Alphaherpesvirinae
''Alphaherpesvirinae'' is a subfamily of viruses in the family ''Herpesviridae'', primarily distinguished by reproducing more quickly than other subfamilies in the ''Herpesviridae''. In animal virology the most important herpesviruses belong to the Alphaherpesvirinae. Pseudorabies virus is the causative agent of Aujeszky's disease in pigs and ''Bovine herpesvirus 1'' is the causative agent of bovine infectious rhinotracheitis and pustular vulvovaginitis. Mammals serve as natural hosts. There are currently 45 species in this subfamily, divided among 5 genera with one species unassigned to a genus. Diseases associated with this subfamily include: HHV-1 and HHV-2: skin vesicles or mucosal ulcers, rarely encephalitis and meningitis, HHV-3: chickenpox (varicella) and shingles, GaHV-2: Marek's disease. Genera ''Alphaherpesvirinae'' consists of the following five genera: * ''Iltovirus'' * ''Mardivirus'' * ''Scutavirus'' * ''Simplexvirus'' * ''Varicellovirus'' The species ''Chelo ...

Equid Alphaherpesvirus 4
''Equid alphaherpesvirus 4'', formerly ''Equine herpesvirus 4'' (EHV-4) is a virus of the family '' Herpesviridae'' that cause rhinopneumonitis in horse The horse (''Equus ferus caballus'') is a domesticated, one-toed, hoofed mammal. It belongs to the taxonomic family Equidae and is one of two extant subspecies of ''Equus ferus''. The horse has evolved over the past 45 to 55 million y ...s. It is the most important viral cause of respiratory infection in foals. Like other herpes viruses, EHV-4 causes a lifelong latent infection in affected animals. These horses are usually the source for new infection for foals over two months old, weanlings, and yearlings. Symptoms include fever, loss of appetite, and discharge from the nose. Most infected animals recover in one to three weeks, but death can occur in environments with overcrowding and other stress factors. There are several vaccines available ( ATCvet codes: inactivated, live, plus various combinations). De ...

Equid Alphaherpesvirus 1
''Equid alphaherpesvirus 1'', formerly ''Equine herpesvirus 1'' (EHV-1), is a virus of the family '' Herpesviridae'' that causes abortion, respiratory disease and occasionally neonatal mortality in horses. Initial spread of EHV-1 by a newly introduced horse through direct and indirect contact can lead to abortion and perinatal infection in up to 70 percent of a previously unexposed herd. Abortion usually occurs in the last four months of gestation, two to four weeks after infection of the mare. Perinatal (around the time of birth) infection can lead to pneumonia and death. Encephalitis can occur in affected animals, leading to ataxia, paralysis, and death. There is a vaccine available (ATCvet code ), however its efficacy is questionable. The virus varies in severity from sub-clinical to very severe. Most horses have been infected with EHV-1, but the virus can become latent and persist without ever causing signs of infection. In 2006, an outbreak of EHV-1 among stables in Flori ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Varicella Zoster Virus
Varicella-zoster virus (VZV), also known as human herpesvirus 3 (HHV-3, HHV3) or ''Human alphaherpesvirus 3'' (taxonomically), is one of nine known herpes viruses that can infect humans. It causes chickenpox (varicella) commonly affecting children and young adults, and shingles (herpes zoster) in adults but rarely in children. VZV infections are species-specific to humans. The virus can survive in external environments for a few hours. VZV multiplies in the tonsils, and causes a wide variety of symptoms. Similar to the herpes simplex viruses, after primary infection with VZV (chickenpox), the virus lies dormant in neurons, including the cranial nerve ganglia, dorsal root ganglia, and autonomic ganglia. Many years after the person has recovered from initial chickenpox infection, VZV can ''reactivate'' to cause shingles. Epidemiology Chickenpox Primary varicella zoster virus infection results in chickenpox (varicella), which may result in complications including encephaliti ...
