| typhus | <disease, microbiology> An acute infectious disease characterised by high fever, a skin eruption and severe headache. In the past, typhus has been a disease of war, famine or catastrophe, being spread by lice, ticks or fleas. The infecting organism is Rickettsia prowazekii, sensitive to sulpha drugs or tetracycline.

| typhus mitior | A mild or abortive typhus. Murine typhus, a milder form of epidemic typhus caused by Rickettsia typhi and transmitted to humans by rat or mouse fleas. Synonym: Congolian red fever, endemic typhus, flea-borne typhus, red fever, red fever of the Congo. North Queensland tick typhus, typhus caused by Rickettsia australis. (05 Mar 2000) |
| typhus vaccine | A formaldehyde-inactivated suspension of Rickettsia prowazekii grown in embryonated eggs; effective against louse-borne (epidemic) typhus; primary immunization consists of two subcutaneous injections 4 or more weeks apart; booster doses are required every 6 to 12 months, as long as the possibility of exposure exists. A vaccine containing living rickettsiae of an attenuated strain of R. Prowazekii has also been used. (05 Mar 2000) |
| typhus, african tick | 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 (tache noire) at the site of the tick bite, swollen glands nearby (satellite lymphadenopathy), and a red raised (maculopapular) rash. Also called fi |

| 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 | A severe acute disease with prolonged high fever up to 40 |
| 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, murine | 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, and urban typhus of malaya. (12 Dec 1998) |
| typhus, queensland tick | 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.

| canine typhus | The uraemic form of canine leptospirosis. Synonym: canine typhus. (05 Mar 2000) |
| Manchurian typhus | Tick transmitted infection with Rickettsia sibirica. See: Korean haemorrhagic fever. Mexican typhus, infection with Rickettsia typhi (mooseri) causing a syndrome similar to epidemic typhus, but spread from rats to man by the rat flea (Xenopsylla (polyplax) cheopis). Spread from rat to rat by the rat louse (Polyplax spinulosa). Most common form of typhus in the United State. It has various geographical names based on region in which it was observed. (05 Mar 2000) |
| rat-flea typhus | Murine 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 and urban typhus of malaya. (12 Dec 1998) |
| recrudescent typhus | Recrudescence of epidemic typhus years after the initial attack. The agent that causes epidemic typhus (Rickettsia prowazekii) remains viable for many years and then when host defenses are down, it is reactivated causing recurrent typhus. The disease is named for the physician Nathan Brill and the great bacteriologist Hans Zinsser. (12 Dec 1998) |

| mite-borne typhus | Scrub: typhus, a mite-borne infectious disease caused by a microorganism, rickettsia tsutsugamushi, characteristically with fever, headache, a raised (macular) rash, swollen glands (lymphadenopathy) and a dark crusted ulcer (called an eschar or tache noire) at the site of the chigger (mite larva) bite. This disease occurs in the area bounded by japan, india, and Australia. Known also as tsutsugamushi disease and tropical typhus. (12 Dec 1998) |
| mite-born typhus | A mild infectious disease first observed in new york city caused by rickettsia akari, transmitted from its mouse host by chigger or adult mite bites. There is fever, a dark spot that becomes a small ulcer at the site of the bite, swollen glands (lymphadenopathy) in that region, and a raised blistery (vesicular) rash. Also known as vesicular rickettsiosis. (12 Dec 1998) |
