卡氏肺孢子虫肺炎(简称PCP)是由卡氏肺孢子虫(简称PC)感染人类引起的疾患。以前认为人类很少感染发病,故一般教科书均先记载。近年国外的研究证明,本病经呼吸道可使小儿或成人感染,表现为散发或流行。现将国外近年的研究状况简介如下。一、历史及病原学Chegas(1909)及Carini(1910)最先描述本病,Delanoe(1912)确定了它的分类学地位。至1938年Ammick和Benneke分别从死婴肺中检出此虫。1952年Vanek等发现PC是流行于当时孤儿收容机构中的间质性浆细胞性肺炎的病原体,直到最近发现本病呈全球性分布。PC属于原生动物,生活周期至今不明。但已知在实验动物肺脏里,必须经过孢囊
Pneumocystis carinii pneumonia (PCP) is a disease caused by infection of humans with Pneumocystis carinii (PC). In the past that humans rarely infected with the disease, it is generally recorded in textbooks. In recent years, foreign studies have shown that the disease can cause respiratory infections in children or adults, showing the distribution or epidemic. Now the research status of foreign countries in recent years are as follows. First, history and etiology Chegas (1909) and Carini (1910) first described the disease, Delanoe (1912) to determine its taxonomic status. By 1938 Ammick and Benneke were detected dead infants lungs in the worm. In 1952, Vanek et al. Found that PC was the causative agent of interstitial plasma cell pneumonia that prevailed in orphanage institutions until recently, and the disease was globally distributed. PC is a protozoan, life cycle so far unknown. However, it is known that in the lungs of experimental animals, cysts must pass
