| focal infection | An old term which distinguishes local infection's (focal) from generalised infection's (sepsis). (05 Mar 2000) |
|---|---|
| focal infection, dental | Secondary or systemic infections due to dissemination throughout the body of microorganisms whose primary focus of infection lies in the periodontal tissues. (12 Dec 1998) |
| food infection | Microbial infection resulting from ingestion of contaminated food. (09 Oct 1997) |
| force of infection | <epidemiology> The per capita rate at which susceptibles are infected. (05 Dec 1998) |
| latent infection | An asymptomatic infection capable of manifesting symptoms under particular circumstances or if activated. (05 Mar 2000) |
| fungal infection | 1. (groin) Tinea cruris is a fungal infection of the perineum, better known as jock itch. This condition is often treated with clotrimazole or miconazole cream. Good general hygiene is vital in the prevention of tinea cruris. Keep the groin area clean and dry and avoid chafing. Launder athletic supporters frequently. Use an antifungal or drying powder after showering. 2. (nail) A fungal infection that involves the fingernails. Nails generally split, flake and grow too thick. 3. (scalp): A fungal scalp infection also known as tinea capitis. A crusting and scaly lesion of the scalp that can also be associated with localised hair loss. Treatment requires oral (systemic) antifungal medications. (05 Jan 1998) |
| fungal nail infection | The most common fungus infection of the nail is onychomycosis. Onychomycosis makes the nails look white and opaque, thickened, and brittle. Older women (perhaps because oestrogen deficiency may increase the risk of infection) and men and women with diabetes or disease of the small blood vessels (peripheral vacscular disease) are at increased risk. Artificial nails (acrylic or wraps ) increase the risk because when an artificial nail is applied, the nail surface is usually abraded with an emery board damaging it, emery boards can carry infection, and water can collect under the nail creating a moist, warm environment for fungal growth. Alternative names include tinea unguium and ringworm of the nails. (12 Dec 1998) |
| lysogenic infection | An infective process characterised by the incorporation of the DNA of the infecting phage into the host cell chromosome. Once incorporated, the phage DNA replicates along with the host DNA. The incorporated phage DNA is relatively inactive, thus permitting the host cell to continue fairly normal life processes. (14 Nov 1997) |
| lytic infection | The normal cycle of infection of a cell by a virus or bacteriophage, in which mature virus or phage particles are produced and the cell is then lysed. (18 Nov 1997) |
| alimentary tract | The passage leading from the mouth to the anus through the pharynx, oesophagus, stomach, and intestine. Synonym: alimentary canal, alimentary tract, digestive tube, tubus digestorius. (05 Mar 2000) |
| alimentary tract smear | A group of cytologic specimens containing material from the mouth (oral smear), oesophagus and stomach (gastric smear), duodenum (paraduodenal smear), and colon, obtained by specialised lavage techniques; used principally for the diagnosis of cancer of those areas. (05 Mar 2000) |
| anterior corticospinal tract | Uncrossed fibres forming a small bundle in the pyramidal tract. See: pyramidal tract. Synonym: tractus corticospinalis anterior, tractus pyramidalis anterior, anterior corticospinal tract, anterior pyramidal fasciculus, direct pyramidal tract, fasciculus corticospinalis anterior, fasciculus pyramidalis anterior, Turck's bundle, Turck's column, Turck's tract. (05 Mar 2000) |
| anterior pyramidal tract | Uncrossed fibres forming a small bundle in the pyramidal tract. See: pyramidal tract. Synonym: tractus corticospinalis anterior, tractus pyramidalis anterior, anterior corticospinal tract, anterior pyramidal fasciculus, direct pyramidal tract, fasciculus corticospinalis anterior, fasciculus pyramidalis anterior, Turck's bundle, Turck's column, Turck's tract. (05 Mar 2000) |
| anterior spinocerebellar tract | A bundle of fibres originating in the base of the posterior horn and zona intermedia throughout lumbosacral segments of the spinal cord, crossing to the opposite side and ascending in a peripheral position in the ventral half of the lateral funiculus. In its ascent through the rhombencephalon, the tract curves sharply dorsalward along the rostral border of the trigeminal motor nucleus, entering the cerebellum in a caudal direction over the dorsal surface of the superior cerebellar peduncle, and terminating as mossy fibres in the granular layer of the cortex of the cerebellar vermis. The bundle conveys proprioceptive and exteroceptive information largely from the opposite lower extremity. Synonym: tractus spinocerebellaris anterior, Gowers' column, Gowers' tract, ventral spinocerebellar tract. (05 Mar 2000) |
| anterior spinothalamic tract | The more anterior or ventral part of the spinothalamic tract that is involved in tactile sensation. See: spinothalamic tract. Synonym: tractus spinothalamicus anterior, ventral spinothalamic tract. (05 Mar 2000) |
