| tropical sore | Infection with promastigotes (leptomonads) of Leishmania tropica and of leishmaniasis major inoculated into the skin by the bite of an infected sandfly, Phlebotomus (commonly P. Papatasi); it is endemic in parts of Asia Minor, northern Africa, and India, and is known by innumerable names, each indicating its locality (e.g., Aleppo, Baghdad, Delhi, or Jericho boil; Aden ulcer; Biskra button); the ulcer begins as a papule that enlarges to a nodule and then breaks down into an ulcer. Two distinctive clinical and epidemiological diseases are recognised, the more common and widespread zoonotic rural disease with a moist acute form, caused by L. Major, with reservoir rodent hosts; and an urban, anthroponotic, dry, chronic form of leishmaniasis caused by leishmaniasis tropica, without a reservoir host, and now largely controlled. See: zoonotic cutaneous leishmaniasis, anthroponotic cutaneous leishmaniasis. Synonym: juccuya, Old World leishmaniasis, tropical sore. (05 Mar 2000) |
| tropical splenomegaly | A chronic disease, occurring in India, Assam, China, the area formerly known as the Mediterranean littoral areas, the Middle East, India, Pakistan, China, South and Central America, Asia, Africa caused by Leishmania donovani and transmitted by the bite of an appropriate species of sandfly of the genus Phlebotomus or Lutzomyia; the organisms grow and multiply in macrophages, eventually causing them to burst and liberate amastigote parasites which then invade other macrophages; proliferation of macrophages in the bone marrow causes crowding out of erythroid and myeloid elements, resulting in leukopenia, and anaemia, splenomegaly, and hepatomegaly which are characteristic, along with enlargement of lymph nodes; fever, fatigue, malaise, and secondary infections also occur; different strains of leishmaniasis donovani occur; leishmaniasis infantum in Eurasia, leishmaniasis chagasi in Latin America.
