Virus
A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. Since Dmitri Ivanovsky's 1892 article describing a non-bacterial pathogen infecting tobacco plants and the discovery of the tobacco mosaic virus by Martinus Beijerinck in 1898,Dimmock p. 4 more than 9,000 virus species have been described in detail of the millions of types of viruses in the environment. Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity. The study of viruses is known as virology, a subspeciality of microbiology. When infected, a host cell is often forced to rapidly produce thousands of copies of the original virus. When not inside an infected cell or in the process of infecting a cell, viruses exist in the form of independent particles, or ''virions'', consisting of (i) the genetic mate ...

Herpesviridae
''Herpesviridae'' is a large family of DNA viruses that cause infections and certain diseases in animals, including humans. The members of this family are also known as herpesviruses. The family name is derived from the Greek word ''ἕρπειν'' ( 'to creep'), referring to spreading cutaneous lesions, usually involving blisters, seen in flares of herpes simplex 1, herpes simplex 2 and herpes zoster (shingles). In 1971, the International Committee on the Taxonomy of Viruses (ICTV) established ''Herpesvirus'' as a genus with 23 viruses among four groups. As of 2020, 115 species are recognized, all but one of which are in one of the three subfamilies. Herpesviruses can cause both latent and lytic infections. Nine herpesvirus types are known to primarily infect humans, at least five of which – herpes simplex viruses 1 and 2 (HSV-1 and HSV-2, also known as HHV-1 and HHV-2; both of which can cause orolabial herpes and genital herpes), varicella zoster virus (or HHV-3; the cau ...

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 years from a small multi-toed creature, '' Eohippus'', into the large, single-toed animal of today. Humans began domesticating horses around 4000 BCE, and their domestication is believed to have been widespread by 3000 BCE. Horses in the subspecies ''caballus'' are domesticated, although some domesticated populations live in the wild as feral horses. These feral populations are not true wild horses, as this term is used to describe horses that have never been domesticated. There is an extensive, specialized vocabulary used to describe equine-related concepts, covering everything from anatomy to life stages, size, colors, markings, breeds, locomotion, and behavior. Horses are adapted to run, allowing them to quickly escape predators, and po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Equine Herpesvirus 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 Flo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Varicellovirus
''Varicellovirus'' (var′i-sel′ō-vi′rŭs) is a genus of viruses belonging to subfamily ''Alphaherpesvirinae'', a member of family ''Herpesviridae''. Humans and other mammals serve as natural hosts. There are 19 species in this genus. Diseases associated with this genus include: HHV-3—chickenpox (varicella) and shingles; BoHV-1—infectious bovine rhinotracheitis/infectious pustular vulvovaginitis (IPV); SuHV-1 (also known as pseudorabies virus)— Aujesky's disease characterized by central nervous system signs (hindleg paralysis, meningoencephalitis), high mortality rates in young animals, and respiratory illness in older pigs. Species The genus consists of the following 19 species: * ''Bovine alphaherpesvirus 1'' * '' Bovine alphaherpesvirus 5'' * '' Bubaline alphaherpesvirus 1'' * '' Canid alphaherpesvirus 1'' * '' Caprine alphaherpesvirus 1'' * '' Cercopithecine alphaherpesvirus 9'' * '' Cervid alphaherpesvirus 1'' * '' Cervid alphaherpesvirus 2'' * '' Cervid alphah ...

Equine Herpesvirus 2
''Equid gammaherpesvirus 2'', formerly ''Equine herpesvirus 2'' (EHV-2), is a virus of the family ''Herpesviridae'', originally known as ''equine cytomegalovirus'' due to its slow replication in tissue culture. However, complete sequencing of the EHV-2 genome has demonstrated that it is a member of the subfamily ''Gammaherpesvirinae'', in the genus ''Percavirus''. It has an uncertain role in respiratory disease in horses, but EHV-2 has been isolated from cases exhibiting symptoms such as coughing, conjunctivitis, and swollen submaxillary and parotid The parotid gland is a major salivary gland in many animals. In humans, the two parotid glands are present on either side of the mouth and in front of both ears. They are the largest of the salivary glands.

Rhadinovirus
''Rhadinovirus'' (synonyms: ''Rhadinoviridae'' and gamma-2 herpesviruses) is a genus of viruses in the order ''Herpesvirales'', in the family ''Herpesviridae'', in the subfamily ''Gammaherpesvirinae''. Humans and other mammals serve as natural hosts. There are 12 species in this genus. Diseases associated with this genus include: Kaposi's sarcoma, primary effusion lymphoma and multicentric Castleman's disease, caused by '' Human gammaherpesvirus 8'' (HHV-8), also known as Kaposi's sarcoma-associated herpesvirus (KSHV). The term rhadino comes from the Latin fragile, referring to the tendency of the viral genome to break apart when it is isolated. Species The genus consists of the following 12 species: * '' Ateline gammaherpesvirus 2'' * '' Ateline gammaherpesvirus 3'' * '' Bovine gammaherpesvirus 4'' * '' Cricetid gammaherpesvirus 2'' * '' Human gammaherpesvirus 8'' * '' Macacine gammaherpesvirus 5'' * '' Macacine gammaherpesvirus 8'' * '' Macacine gammaherpesvirus 11'' * '' Ma ...

Equine Herpesvirus 3
''Equid alphaherpesvirus 3'', formerly ''Equine herpesvirus 3'' (EHV-3), is a virus of the family ''Herpesviridae'' that affects horses. Pathology It causes a disease known as equine coital exanthema. The disease is spread through direct and sexual contact, contaminated handlers and equipment, and possibly through flies carrying infected vaginal discharge. EHV-3 has an incubation period of as little as two days. Signs of the disease include often painful pustules and ulcerations of the vagina, penis, prepuce, and perineum. Lesions may also be seen on the lips and teats. Usually the only symptom seen is a decreased libido Libido (; colloquial: sex drive) is a person's overall sexual drive or desire for sexual activity. Libido is influenced by biological, psychological, and social factors. Biologically, the sex hormones and associated neurotransmitters that act u ... in stallions. The lesions heal within two weeks.

Equine Herpesvirus 4
''Equid alphaherpesvirus 4'', formerly ''Equine herpesvirus 4'' (EHV-4) is a virus of the family ''Herpesviridae'' that cause rhinopneumonitis in horses. 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 The Anatomical Therapeutic Chemical (ATC) Classification System is a drug classification system that classifies the active ingredients of drugs according to the organ or system on which they act and their therapeutic, pharmacological and chemical ... codes: inactivated, live, plus various combinations).
