Ｒｈｉｎｏｐｏｒｉｄｉｕｍｓｅｅｂｅｒｉ,一种能够感染人和动物粘膜上皮的微生物 ,根据其形态学和组织学特征被分类为一种真菌。利用共享序列多聚酶链反应(ＰＣＲ)直接从感染的组织中扩增Ｒ .ｓｅｅｂｅｒｉ 18ＳｒＲＮＡ的基因片段。基因序列分析和种系发生关系的推论表明 Rhinoporidium seberberi, a microorganism that infects human and animal mucosal epithelium, is classified as a fungus according to its morphological and histological features. Gene fragments of R.seeberi 18S rRNA were amplified directly from infected tissues using shared sequence polymerase chain reaction (PCR). Inference of gene sequence analysis and phylogenetic relationships suggests
