鸟—胞内复合分支杆菌(Mycobacterium aviumComplex,Ma—c)感染是艾滋病患者最常见的机会致病菌感染,而且与艾滋病(AIDS)患者的高病死率显著相关.AIDS流行之前Ma—c很少引起人类感染,播散性(disseminated)鸟一胞内复合分支杆菌(dMa—c)感染更为罕见.但随着AIDS的传播流行,患者中dMa—c 感染日益增多.调查表明,AIDS患者生前15%～40%,死后尸检50%以上的病例发现dMa—c感染.为此国外医学界进行了许多研究.本文综述了其病原学、流行病学和临床等方面研究进展.
Bird-Mycobacterium avium complex (Ma-c) infection is the most common opportunistic pathogen infection in AIDS patients and is significantly associated with a high case-fatality rate in AIDS patients. Ma-c was rare before the AIDS epidemic Causing infection in humans, disseminated avian mycobacterium intracellulare (dMa-c) infection is more rare, but with the spread of AIDS, dMa-c infection in patients is increasing.Research shows that AIDS patients before 15% ~ 40%, and post mortem autopsy more than 50% of the cases found dMa-c infection.Therefore, many studies have been carried out in the field of foreign medical science.This paper reviews the progress of its etiology, epidemiology and clinical aspects.
