| tick-borne encephalitis | 1. (Central European subtype) tick-borne meningoencephalitis caused by a flavivirus closely related to the virus causing the Far Eastern type; it is transmitted by Ixodes ricinus, also by infected raw milk, especially that of goats. Synonym: biundulant meningoencephalitis, Central European tick-borne fever, diphasic milk fever, Russian spring-summer encephalitis (Western subtype). 2. (Eastern subtype) tick-borne encephalitis, a severe form of encephalitis caused by a flavivirus, a virus belonging to the Flaviviridae family, and transmitted by ticks (Ixodes pertulcatus and I. Ricinus). Synonym: Russian tick-borne encephalitis. (05 Mar 2000) |

| tick-borne encephalitis virus | An arbovirus of the genus Flavivirus that occurs in Central Europe and the USSR in two subtypes, causing two forms of encephalitis in humans: tick-borne encephalitis (Central European subtype) and tick-borne encephalitis (Eastern subtype); the vectors are ticks of the genus Ixodes. Synonym: Russian spring-summer encephalitis virus, tick-borne virus. (05 Mar 2000) |
| tick-borne fever | A rickettsial disease of ruminants transmitted by the tick Ixodes ricinus in Europe and Rhipicephalus haemaphysaloides supina in India and characterised by pyrexia, depression, and anorexia. (05 Mar 2000) |
| tick-borne rickettsioses of the eastern hemisphere | Thare are 3 known diseases caused by infection with rickettsial agents. They are north asian tick-borne rickettsiosis, queensland tick typhus, and african tick typhus (fi |
| tick-borne rickettsiosis, north asian | One of the tick-borne rickettsial diseases of the eastern hemisphere, similar to rocky mountain spotted fever, but less severe, with fever, a small ulcer (eschar) at the site of the tick bite, swollen glands nearby (satellite lymphadenopathy), and a red raised (maculopapular) rash.

| tick-borne virus | An arbovirus of the genus Flavivirus that occurs in Central Europe and the USSR in two subtypes, causing two forms of encephalitis in humans: tick-borne encephalitis (Central European subtype) and tick-borne encephalitis (Eastern subtype); the vectors are ticks of the genus Ixodes. Synonym: Russian spring-summer encephalitis virus, tick-borne virus. (05 Mar 2000) |
| tooth-borne | A term used to describe a prosthesis or part of a prosthesis which depends entirely upon the abutment teeth for support. (05 Mar 2000) |
| tooth-borne base | The denture base restoring an edentulous area which has abutment teeth at each end for support; the tissue which it covers is not used for support. (05 Mar 2000) |
| encephalitis, tick-borne | A disease caused by tick-borne encephalitis virus, a species of flavivirus, and a member of the subgroup encephalitis viruses, tick-borne. Tick-borne encephalitis appears to be a spectrum of disease caused by two related viruses: the european subtype - central european encephalitis virus and the eastern subtype - russian spring-summer encephalitis virus. (12 Dec 1998) |
| encephalitis viruses, tick-borne | A subgroup of the genus flavivirus that causes encephalitis and haemorrhagic fevers and is found in eastern and western europe and the former soviet union. It is transmitted by tick vectors and there is an associated milk-borne transmission from viraemic cattle, goats, and sheep. (12 Dec 1998) |
| typhus, endemic flea-borne | An infectious disease clinically similar to epidemic louse-borne typhus (typhus, epidemic louse-borne), but caused by rickettsia typhi, which is transmitted from rat to man by the rat flea, xenopsylla cheopis. (12 Dec 1998) |
| typhus, epidemic louse-borne | The classic form of typhus, caused by rickettsia prowazekii, which is transmitted from man to man by the louse pediculus humanus corporis. This disease is characterised by the sudden onset of intense headache, malaise, and generalised myalgia followed by the formation of a macular skin eruption and vascular and neurologic disturbances.

| typhus, mite-borne | See Typhus, scrub. (12 Dec 1998) |
| flea-borne typhus | An acute infectious disease with fever, headache, and rash, all quite similar to, but milder than, epidemic typhus, caused by a related microoganism, rickettsia typhi (mooseri), transmitted to humans by rat fleas (xenopsylla cheopis). The animal reservoir includes rats, mice and other rodents. Murine typhus occurs sporadically worldwide but is more prevalent in congested rat-infested urban areas. Also known as endemic typhus, rat-flea typhus; urban typhus of malaya). (12 Dec 1998) |
