利什曼蟲(chóng)檢測(cè)試劑盒

利什曼蟲(chóng)leishmanioses的病原體。利什曼蟲(chóng)屬的許多物種對(duì)人類致病性沒(méi)有顯示形態(tài)學(xué)差異。它們可以分化的基礎(chǔ)上生物標(biāo)準(zhǔn),實(shí)驗(yàn)分析了不同臨床圖片和流行病學(xué)的事實(shí)(見(jiàn)標(biāo)簽。)。
利什曼蟲(chóng)屬Phlebotomus雌蚊的傳播和Lutzomyia(白蛉?),發(fā)生在溫暖地區(qū)的國(guó)家在亞洲、非洲、歐洲地中海國(guó)家和拉丁美洲。無(wú)鞭毛體階段的寄生蟲(chóng)攝取的昆蟲(chóng)腸道的血被轉(zhuǎn)換成纖細(xì),鞭打promastigote形式,繁殖和遷移回吻。當(dāng)感染白蛉再bloodmeal promastigote形式被接種到一個(gè)新主機(jī)(人類或其它脊椎動(dòng)物)。
在宿主promastigotes迅速轉(zhuǎn)變成無(wú)鞭毛體階段(12 - 14小時(shí)內(nèi)),然后釋放過(guò)程類似胞外分泌和可以感染新的細(xì)胞。在皮膚和黏膜與皮膚的leishmanioses寄生蟲(chóng)一般仍局限于皮膚或皮膚和粘膜。皮膚leishmanioses病變可能持續(xù)很長(zhǎng)一段時(shí)間,但往往自發(fā)愈合,而更傾向于破壞性變化在黏膜與皮膚的leishmanioses感染。相比之下在內(nèi)臟leishmanioses有機(jī)體可以入侵整個(gè)單核吞噬系統(tǒng)各器官(脾、肝、淋巴結(jié)、節(jié)點(diǎn)、骨髓、血液?jiǎn)魏思?xì)胞等),導(dǎo)致感染,沒(méi)有治療通常是致命的。

Leishmania infantum

Leishmania is the causative agent of leishmanioses. The many species of the genus Leishmania pathogenic to humans do not show morphological differences. They can be differentiated on the basis of biological criteria, laboratory analyzes the different clinical pictures and epidemiological facts (see tab.). 
Leishmania are transmitted by female mosquitoes of the genera Phlebotomus and Lutzomyia (?sandflies?), that occur in warmer regions of countries in Asia, Africa, Europe (Mediterranean countries) and Latin America. The amastigote stages of the parasite ingested by the insect with a blood meal are transformed in its intestine into slender, flagellate promastigote forms, which multiply and migrate back into the proboscis. When infected sandflies take another bloodmeal the promastigote forms are inoculated into a new host (humans or other vertebrates). 
In the host the promastigotes quickly (within 12-14 hours) transform into amastigote stages, which then released in a process resembling exocytosis and can infect new cells. In cutaneous and mucocutaneous leishmanioses the parasites generally remain restricted to the skin or skin and mucosa. Cutaneous leishmanioses lesions may persist for long periods, but tend to heal spontaneously, whereas a greater tendency to destructive changes is seen in mucocutaneous leishmanioses infections. By contrast in visceral leishmanioses the organism can invade the entire mononuclear phagocytic system in various organs (spleen, liver, lymph, nodes, bone marrow, blood monocytes etc.), causing infections that are normally lethal without treatment.  

Infections may be diagnosed by:

Microscopy:      
determination of the pathogen in coloured Giemsa-stained smears

Serology:          
determination of specific antibodies based on the ELISA-technique
