| ARV | acquired immunodeficiency syndrome-related virus; anterior right ventricle; avian reovirus |
| ASV | anodic stripping voltammetry; antisiphon valve; antisnake venom; avian sarcoma virus |
| ECAO | enteric cytopathogenic avian orphan [virus] |
| Vir | virus, viral |
| tuberculosis, avian | A variety of tuberculosis affecting various birds, including chickens and ducks. It is caused by mycobacterium avium and characterised by tubercles consisting principally of epithelioid cells. It may be transmitted to other animals including man. (12 Dec 1998) |
|---|---|
| bovine virus diarrhoea virus | A virus of the genus Pestivirus, in the family Togaviridae, causing bovine virus diarrhoea; New York, Oregon, and Indiana strains of the virus are recognised. Synonym: mucosal disease virus. (05 Mar 2000) |
| acute rheumatic arthritis | Arthritis due to rheumatic fever. (05 Mar 2000) |
| arthritis | <rheumatology> An inflammatory condition that affects joints. Can be infective, autoimmune, traumatic in origin. Origin: Gr. Arthron = joint (18 Nov 1997) |
| arthritis, adjuvant | An arthritis experimentally induced in animals with freund's adjuvant. (12 Dec 1998) |
| arthritis deformans | A systemic disease, seen more commonly in women which affects connective tissue, particularly the synovial tissue within joints. Arthritis is the main clinical feature and involves many joints in the body, especially those of the hand and feet. In this disease, there is thickening of the soft tissues around the joints and extension of the synovial tissue over articular cartilage (which becomes eroded). A chronic and progressive course is common with joint deformities and disability. Juvenile rheumatoid arthritis is a variant which affects children. (27 Sep 1997) |
| arthritis, degenerative | A type of arthritis caused by inflammation, breakdown, and eventual loss of the cartilage of the joints. Also called osteoarthritis. (12 Dec 1998) |
| arthritis, gout | Joint inflammation caused by uric acid crystal deposits in the joint space An attack is usually extremely painful.The uric acid crystals are deposited in the joint fluid (synovial fluid) and joint lining (synovial lining). Intense joint inflammation occurs as white blood cells engulf the uric acid crystals, causing pain, heat, and redness of the joint tissues. The term gout commonly is used to refer to these painful arthritis attacks but gouty arthritis is only one manifeatation of gout. (12 Dec 1998) |
| arthritis, gouty | Arthritis, especially of the great toe, as a result of gout. Acute gouty arthritis often is precipitated by trauma, infection, surgery, etc. The initial attacks are usually monoarticular but later attacks are often polyarticular. (12 Dec 1998) |
| arthritis in children | Arthritis is not just a problem for the retired. It can and does affect children in the form of juvenile/paediatric arthritis. (12 Dec 1998) |
| arthritis, infectious | Arthritis caused by bacteria, rickettsiae, mycoplasmas, viruses, fungi, or parasites. Bacterial arthritis is frequently caused by staphylococcus aureus, streptococcus pneumoniae, haemophilus influenzae, and neisseria gonorrhoeae. Viral arthritis is less common than bacterial arthritis and may be a manifestation of such viral diseases as mumps, rubella, hepatitis, etc. (12 Dec 1998) |
| arthritis, juvenile rheumatoid | Rheumatoid arthritis of children occurring in three major subtypes defined by the symptoms present during the first six months following onset: systemic-onset (still's disease, juvenile-onset) polyarticular-onset, and pauciarticular-onset. Adult-onset cases of still's disease (still's disease, adult-onset) are also known. Only one subtype of juvenile rheumatoid arthritis (polyarticular-onset, rheumatoid factor-positive) clinically resembles adult rheumatoid arthritis and is considered its childhood equivalent. (12 Dec 1998) |
| arthritis, lyme | Inflammation of the joints associated with Lyme disease, a bacterial disease spread by ticks. (12 Dec 1998) |
| arthritis mutilans | A form of chronic rheumatoid arthritis in which osteolysis occurs with extensive destruction of the joint cartilages and bony surfaces with pronounced deformities, chiefly of the hands and feet; similar changes can occur in some cases of psoriatic arthritis. (05 Mar 2000) |
| arthritis nodosa | <disease> A systemic disease, seen more commonly in women which affects connective tissue, particularly the synovial tissue within joints. Arthritis is the main clinical feature and involves many joints in the body, especially those of the hand and feet. In this disease, there is thickening of the soft tissues around the joints and extension of the synovial tissue over articular cartilage (which becomes eroded). A chronic and progressive course is common with joint deformities and disability. Juvenile rheumatoid arthritis is a variant which affects children. (11 Nov 1997) |
