Abstract

 

Identity of causative agent of rhinosporidiosis (Rhinosporidium seeberi ) has been controversial since the disease was described in 1900. Extensive sequence alignments and phylogenetic analyses of 16S rRNA gene detected recently by us in R. seeberi , revealed 99% similarity with 16S rDNA in chloroplasts of flowering plants. Study demonstrates R. seeberi is a pigmented prokaryote displaying some characteristics of cyanobacteria, and contains 16S rDNA present in chloroplasts of all groups of land plants. This study and our recent publication of 2006 are the first molecular studies using purified organismal DNA extracted from R. seeberi free of infected tissue.
