Genetically distinct forms of Pneumocystis carinii infect several mammalian hosts. We report the amplification of P. carinii DNA from samples of two infected thoroughbred foal lungs by using primers designed from the sequence of a P. carinii mitochondrial rRNA gene; these primers also prime the amplification of P. carinii DNA from other hosts. The nucleotide sequence of part of the mitochondrial rRNA gene amplified from P. carinii infecting one of the foals was determined and found to be distinct from that of published rat-, rabbit-, ferret-, and human-derived P. carinii sequences.
卡氏肺孢子虫的基因不同形式感染几种哺乳动物宿主。我们报告了通过使用根据卡氏肺孢子虫线粒体rRNA基因序列设计的引物,从两匹受感染纯种马驹肺样本中扩增卡氏肺孢子虫DNA;这些引物也能引发从其他宿主中扩增卡氏肺孢子虫DNA。测定了从感染其中一匹马驹的卡氏肺孢子虫中扩增的线粒体rRNA基因部分的核苷酸序列,发现其与已发表的源自大鼠、兔子、雪貂和人类的卡氏肺孢子虫序列不同。
