Pseudocowpox is a disease caused by Pseudocowpox virus (also known as "paravaccinia"), a virus of the family Poxviridae and the genus Parapoxvirus . [2] :393 Pseudocowpox is a worldwide disease of cattle. Symptoms include ring or horseshoe shaped scabs on the teats, which usually heal within six weeks. [3] Lesions may also develop on the muzzles and in the mouths of nursing calves. Spread is by fomites, including hands, calves' mouths, and milking machines.

Paravaccinia virus is a viral infection of the Parapoxvirus genus of viruses. Human can contract the virus from contact with livestock infected with Bovine papular stomatitis and is common with ranchers, milkers, and veterinarians. Infection will present with fever, fatigue, and lesion on the skin.

Virus Type of non-cellular infectious agent

A virus is a small infectious agent that replicates only inside the living cells of an organism. Viruses can infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea.

<i>Poxviridae</i> pox virus

Poxviridae is a family of viruses. Humans, vertebrates, and arthropods serve as natural hosts. There are currently 69 species in this family, divided among 28 genera, which are divided into two subfamilies. Diseases associated with this family include smallpox.

Lesions may also appear on the hands of milkers, a clinical presentation known as milker's nodule. This disease in humans is nearly identical to orf. [4]

Orf (disease) Human disease

Orf is an exanthemous disease caused by a parapox virus and occurring primarily in sheep and goats. It is also known as contagious pustular dermatitis, infectious labial dermatitis, ecthyma contagiosum, thistle disease and scabby mouth. Orf virus is zoonotic—it can also infect humans.

Feline panleukopenia

Feline panleukopenia virus (FPLV) is a species of parvovirus that can infect all wild and domestic members of the felid (cat) family worldwide. It is a highly contagious, severe infection that causes gastrointestinal, immune system, and nervous system disease.

Infectious canine hepatitis (ICH) is an acute liver infection in dogs caused by Canine mastadenovirus A, formerly called Canine adenovirus 1 (CAV-1). CAV-1 also causes disease in wolves, coyotes, and bears, and encephalitis in foxes. The virus is spread in the feces, urine, blood, saliva, and nasal discharge of infected dogs. It is contracted through the mouth or nose, where it replicates in the tonsils. The virus then infects the liver and kidneys. The incubation period is 4 to 7 days.

Bovine alphaherpesvirus 2 (BoHV2) is a virus of the family Herpesviridae that causes two diseases in cattle, bovine mammillitis and pseudo-lumpy skin disease. BoHV2 is similar in structure to human herpes simplex virus.

Equid alphaherpesvirus 3, formerly Equine herpesvirus 3 (EHV-3), is a virus of the family Herpesviridae that affects horses. It causes a disease known as equine coital exanthema. The disease is spread through direct and sexual contact 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 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 in stallions. The lesions heal within two weeks. As with other herpes viruses, the virus remains latent in the host for life. Carrier animals can sometimes be identified by spots of pigment loss on black skin in the genital region. EHV-3 is best prevented by taking note of present clinical signs and keeping infected horses isolated and breeding stock from sexual contact with other horses. Antibiotic ointments should be used on the lesions to prevent secondary bacterial infections and hasten the healing process. It is also important to use disposable gloves and instruments in veterinary exams as the virus can be spread by using contaminated equipment.

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.

Duck plague Disease caused by Anatid alphaherpesvirus 1 of the family Herpesviridae that causes acute disease with high mortality rates in flocks of ducks, geese, and swans

Duck plague is a worldwide disease caused by Anatid alphaherpesvirus 1 of the family Herpesviridae that causes acute disease with high mortality rates in flocks of ducks, geese, and swans. It is spread both vertically and horizontally—through contaminated water and direct contact. Migratory waterfowl are a major factor in the spread of this disease as they are often asymptomatic carriers of disease. The incubation period is three to seven days. Birds as young as one week old can be infected. DVE is not zoonotic.

Bovine malignant catarrhal fever cattle disease

Bovine malignant catarrhal fever (BMCF) is a fatal lymphoproliferative disease caused by a group of ruminant gamma herpes viruses including Alcelaphine gammaherpesvirus 1 (AlHV-1) and Ovine gammaherpesvirus 2 (OvHV-2) These viruses cause unapparent infection in their reservoir hosts, but are usually fatal in cattle and other ungulates such as deer, antelope, and buffalo. In Southern Africa the disease is known as snotsiekte, from the Afrikaans.

Buffalopox

Buffalopox is caused by buffalopox virus (BPXV); it is a Poxviridae for which the natural host is buffalo. It mainly infects buffalo but has been known to infect cows and humans. It is classified in the Orthopoxvirus (OPV) genus and the subfamily Chordopoxvirinae. The appearance of buffalopox follows a pattern and is described as emerging and re-emerging, it commonly occurs in sporadic and epidemic forms in domestic and commercial farm settings.

Camelpox is a disease of camels caused by a virus of the family Poxviridae, subfamily Chordopoxvirinae, and the genus Orthopoxvirus. It causes skin lesions and a generalized infection. Approximately 25% of young camels that become infected will die from the disease, while infection in older camels is generally more mild. Although rare, the infection may spread to the hands of those that work closely with camels.

Ectromelia virus (ECTV) is a virus of the family Poxviridae and the genus Orthopoxvirus that causes mousepox, a disease of mice. It has only been seen in mouse colonies kept for research purposes. Mousepox causes skin lesions and generalized disease, which can be fatal. It is the only poxvirus to cause disease naturally in mice.

Bovine papular stomatitis is a disease caused by Bovine papular stomatitis virus, of the family Poxviridae and the genus Parapoxvirus. It occurs worldwide in cattle. Symptoms include reddish, raised, sometimes ulcerative lesions on the lips, muzzle, and in the mouth. It usually occurs before the age of two years. Reinfection is possible because of the short duration of immunity. Clinically, the disease is mild, but its importance lies in the need to differentiate it from foot-and-mouth disease. There have been reports of both lesions on the hands of milkers and similar infections in sheep and goats, as well as humans.

Sheeppox species of virus

Sheeppox is a highly contagious disease of sheep caused by a poxvirus different from the benign orf. This virus is in the family Poxviridae and genus Capripoxvirus. Sheeppox virus (SPV) is the most severe of all the animal pox diseases and can result in some of the most significant economic consequences due to poor wool and leather quality.

Lumpy skin disease (LSD) is an infectious disease in cattle caused by a virus of the family Poxviridae, also known as Neethling virus. The disease is characterized by fever, enlarged superficial lymph nodes and multiple nodules on the skin and mucous membranes. Infected cattle also may develop edematous swelling in their limbs and exhibit lameness. The virus has important economic implications since affected animals tend to have permanent damage to their skin, lowering the commercial value of their hide. Additionally, the disease often results in chronic debility, reduced milk production, poor growth, infertility, abortion, and sometimes death.

Fowlpox is the worldwide disease of poultry caused by viruses of the family Poxviridae and the genus Avipoxvirus. The viruses causing fowlpox are distinct from one another but antigenically similar, possible hosts including chickens, turkeys, quail, canaries, pigeons, and many other species of birds. There are two forms of the disease. The first is spread by biting insects and wound contamination and causes lesions on the comb, wattles, and beak. Birds affected by this form usually recover within a few weeks. The second form is spread by inhalation of the virus and causes a diphtheritic membrane to form in the mouth, pharynx, larynx, and sometimes the trachea. The prognosis for this form is poor.

Rabbitpox is a disease of rabbits caused by a virus of the genus Orthopoxvirus and the family Poxviridae. Rabbitpox was first isolated at the Rockefeller Institute in New York in 1933, following a series of epidemics in the laboratory rabbits. It is an acute disease only known to infect laboratory rabbits as no cases have been reported in wild rabbits; it also cannot infect humans.
