The causative agent of rhinosporidiosis is a microscopic round body in polypoidal masses that is believed to be the sporangium of a fungus Rhinosporidium seeberi. But fungal aetiology can not be proved with certainty. Attempts to culture the fungus on various media have also been unsuccessful. In a recent study pond water samples, from water in which(More)

Fungal etiology is widely quoted for the disease rhinosporidiosis. Identity of the fungal sporangium and its relationship with the disease have baffled medical scientists and mycologists for several decades. This study provides unequivocal evidence against involvement of fungus in rhinosporidiosis. The so-called sporangium is found to be a unique body(More)
We have been able to isolate the cyanobacterium Microcystis aeruginosa from water samples of ponds and river where patients of rhinosporidiosis were bathing. It is likely that this cyanobacterium is the causative agents of this disease. The bluish-green cells of M. aeruginosa also have a colorless small cell stage called nanocyte which has been detected in(More)
Polyps of rhinosporidiosis contain microscopic round bodies, believed to be causative agents of the disease. The source and identity of these round bodies has been debated ever since the first case was described in the year 1900. Most patients have a history of exposure to pond water. Collection and microscopic analysis of pond water samples where patients(More)
A technique for the study of the cytoskeleton by transmission electron microscopy is described. It preserves cytoplasmic and nuclear ultrastructural details as well as cytoskeletal elements enabling a correlated study. There are no significant differences in organization and distribution of intermediate filaments between cancerous and normal breast cells.(More)
UNLABELLED 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.(More)
The peritumoural region of a squamous cell carcinoma of the tongue when examined with light and electron microscope showed nodular bodies in the submucosa with all the distinctive features of 'sporangium and 'spores' of rhinosporidiosis. The occurrence of rhinosporidiosis in the tongue along with malignancy has not been reported hitherto. Some interesting(More)
