| HIV wasting syndrome | <syndrome> Involuntary weight loss of greater than 10 percent associated with intermittent or constant fever and chronic diarrhoea or fatigue for more than 30 days in the absence of a defined cause other than HIV infection. A constant feature is major muscle wasting with scattered myofibre degeneration. A variety of aetiologies, which vary among patients, contributes to this syndrome. (12 Dec 1998) |
|---|---|
| agonal infection | An acute infection, commonly pneumonic or septic, occurring toward the end of any disease and often the cause of death. Synonym: agonal infection. (05 Mar 2000) |
| airborne infection | A mechanism of transmission of an infectious agent by particles, dust, or droplet nuclei suspended in the air. (05 Mar 2000) |
| apical infection | Implantation of microorganisms at the apex of a tooth, usually the result of the migration of microorganisms from the pulp canal through the apical foramen. (05 Mar 2000) |
| arbovirus infection | <virology> A type of viral infection that is transmitted by mosquitoes in late spring to early autumn. One manifestation is encephalitis (central nervous system infection). (27 Sep 1997) |
| ascariasis infection | <microbiology> Infection by the nematode Ascaris lumbricoides and is characterised by an early pulmonary phase related to larval migration and a later, prolonged intestinal phase. Adult worms are 15-40 cm in length and maintain themselves in the lumen of the small intestine. Infection occurs after ingesting eggs contained in contaminated food or more commonly, by transmission to the mouth by the hands after contact with contaminated soil. Treatment is with mebendazole or pyrantel pamoate. (27 Sep 1997) |
| atypical mycobacterial infection | <microbiology> Infection with organisms from the Mycobacterium genus other than tuberculosis. Risk factors include immunocompromised patients and those with AIDS. Mycobacterium avium intracellulare is an example which frequently infects AIDS patients. Atypical mycobacterial infections can cause abscesses, septic arthritis and osteomyelitis. Treatment can be difficult due to the emergence of resistance to standard antitubercular antibiotics. (27 Sep 1997) |
| bacterial infection | <microbiology> Bacteria are group of micro-organisms that are a single cell approximately 1 micron in transverse diameter. Some bacteria cause disease in man, requiring treatment with an antibiotic. (27 Sep 1997) |
| bladder infection | Some people are at more risk for bladder and other urinary tract infections (UTIs) than others. One woman in five develops a UTI during her lifetime. Not everyone with a UTI has symptoms. Common symptoms include a frequent urge to urinate and a painful, burning when urinating. Underlying conditions that impair the normal urinary flow can lead to more complicated UTIs. (12 Dec 1998) |
| breast infection | <microbiology> Inflammation of the breast tissue most often caused by a bacterial infection. Staphylococcus is the most common organism. This breast infection is seen most commonly in the immediate postpartum period (during breast-feeding). Treatment includes warm wet compresses to the site and oral antibiotics. (27 Sep 1997) |
| parasitic infection | <microbiology> A successful invasion of a host by an organism that uses the host for food and shelter. (27 Sep 1997) |
| germinal infection | Infection of a baby with a disease by way of a parent's gamete (sperm or ovum). (09 Oct 1997) |
| mass infection | Infection resulting from the entrance of a large number of pathogens into the circulation or tissues. (05 Mar 2000) |
| Vincent's infection | An acute or recurrent gingivitis of young and middle-aged adults characterised clinically by gingival erythema and pain, fetid odour, and necrosis and sloughing of interdental papillae and marginal gingiva which gives rise to a gray pseudomembrane; fever, regional lymphadenopathy, and other systemic manifestations also may be present. A fusiform bacillus and Treponema vincentii can be isolated from the gingival tissues in large numbers and are felt to play a significant but poorly defined role in the pathogenesis. Synonym: fusospirochetal gingivitis, trench mouth, ulceromembranous gingivitis, Vincent's disease, Vincent's infection. (05 Mar 2000) |
| viral infection | The successful invasion, establishment and growth of viruses in the tissues of the host. (27 Sep 1997) |
