viral arthritis

viral

pertaining to or caused by a virus.

---

viral abortion

see equine viral abortion (below). See also equine viral rhinopneumonitis, equine viral arteritis, infectious bovine rhinotracheitis.

viral arteritis

see equine viral arteritis.

viral arthritis

a contagious disease of chickens and turkeys caused by a reovirus and characterized by a high incidence of inapparent infection and some cases of joint swelling and lameness.

viral assembly

final steps in the replication of viruses in which virions are assembled from their separately synthesized components. The final steps of viral maturation prior to release from the cell.

viral cultivation

viruses grow only in living cells which in the laboratory are provided by embryonated hen eggs, cell culture, or laboratory animals (rabbits, mice, etc.).

viral diarrhea

occurs in most species, especially in the newborn. In cattle, rotavirus and coronavirus are the common agents but bovine herpesvirus 1 and others may also be the cause in this age group. In older cattle bovine virus diarrhea (mucosal disease) is the major cause. Some other diseases may have diarrhea as an incidental sign, e.g. rinderpest, bovine malignant catarrhal fever.

equine viral abortion

caused by equine herpesvirus 1, sometimes equine herpesvirus 4. Abortion occurs in the last trimester and often involves a majority of mares in a group (abortion storm). See also equine viral rhinopneumonitis, equine viral arteritis.

viral hemorrhagic septicemia

important rhabdoviral infection of rainbow trout. Also causes infection, and sometimes disease, in other salmonids, pike, turbot, Pacific cod and Pacific herring. Acute infection is characterized by hemorrhages and a high mortality. Chronic infection may be inapparent.

viral hepatitis

see duck hepatitis.

viral interstitial pneumonia

bovine syncytial virus, a common cause of interstitial pneumonia in all age cattle, especially calves.

viral ligand

a receptor binding molecule on the surface of a virus. See also ligand.

viral papular dermatitis

see equine papular dermatitis.

viral pneumonia

see enzootic pneumonia.

viral pneumonia calf

caused by parainfluenza-3 virus, bovine respiratory syncytial virus; infection with Mycoplasma, Ureaplasma, Pasteurella spp. may also accompany the viral infection.

viral recombination

see recombination.

viral replication

see replication.

viral teratogen

see akabane virus disease, aino virus disease, bovine virus diarrhea, rift valley fever, wesselsbron disease, bluetongue, border disease, classical swine fever (hog cholera), feline panleukopenia.

viral transcription

see transcription.

viral arthritis

Rheumatology A transient and nonspecific inflammatory response of one or more joints to a viral infection–eg, mumps, rubella, human parvovirus, and HBV, which may also follow rubella vaccination. See Arthritis.
