Rhinosporidium
Abstract
Two dogs, 4 and 7 years of age, were presented for evaluation and treatment of excessive sneezing. Physical examinations in both cases were within acceptable limits except for the presence of a single mass in the left nasal passage in the first case and left-sided nasal discharge in the second case....

Abstract
One hundred forty-three cases of rhinosporidiosis, confirmed by smear or biopsy, treated in two major General Hospitals in Sri Lanka over a 14 year period (1995-2009) were analyzed in regard to their epidemiological, clinical, clinicopathological, immunological and microbiological features. Regional...

Abstract
Rhinosporidiosis in an Indian male with a tumorous skin lesion is reported. Histopathology from the skin lesion revealed gigantic foreign body giant cells bloated with multiple, engulfed sporangia of rhinosporidiosis, which has not been reported earlier. The term "dermosporidiosis", should be used t...

Abstract
We report a case of cutaneous rhinosporidiosis localized in the nasal philtrum. The patient's complaints started 3 months prior to being seen in our clinics. Ear, nose, and throat examination showed the presence of a polypoid lesion filling the right nostril. Complete surgical resection of the polyp...

Abstract
We report the case of a young Chhattisgarhi male with polymorphic dermosporidiosis (cutaneous rhinosporidiosis). He had multiple subcutaneous nodules and an ecthymatoid skin lesion along with nasal rhinosporidiosis. The diagnosis was confirmed by demonstration of sporangia with endospores in fine-ne...

Abstract
Rhinosporidiosis is endemic in the state of Chhattisgarh. 462 cases were encountered during the period of 12 years from January 1994 to December 2005. Maximum incidence was seen in men in the age group of 21-30 years. Nose and nasopharynx were the commonest site (81.1%), followed by ocular tissue (1...

Abstract
We noted Rhinosporidium seeberi organisms as the main causative agent. Males were affected three times more than females. Children less than 10 years of age comprised more than 50% of our series. In 91% of cases, the conjunctiva was the site of this infection. Total excision of fungal mass was carri...

CASE REPORT: In India and Southeast Asia, rhinosporidiosis is a common infectious disease, but it has rarely been reported in western countries. Infrequently, isolated ocular rhinosporidial infections have been reported, but to our knowledge, there are no reported cases in Canada. Two cases of rhino...

The effects of biocides (antiseptics and disinfectants) on the endospores of Rhinosporidium seeberi.
Abstract
No data exists on the activity of biocides (antiseptics and disinfectants) on Rhinosporidium seeberi that causes rhinosporidiosis in humans and animals. On account of the inability to culture R. seeberi, in vitro, dyes were used to assess the morphological integrity and viability of biocide-treated...

Abstract
We report, for the first time, (i) reactions of the endospores with the salt MTT (3-[4,5-dimethyl-2-thiazolyl]-2,5-diphenyl-2H-tetrazolium bromide) and (ii) ultrastructural appearances; and suggest that both views on the nature of spherical bodies are valid (i.e. the endospore contains both EDB, and...

Abstract
R. seeberi, the pathogen that causes rhinosporidiosis, has been definitively classified using molecular biological tools in a new clade - the Mesomycetozoea, along with 10 parasitic and saprobic microbes. The controversial spherical bodies of the endospores have been shown to comprise both lipid/pro...

Abstract
The taxonomic relationship of Rhinosporidium seeberi with other organisms remained controversial for over a century. Recently, molecular studies have shown R. seeberi to be a protistal microbe in the newly described class Mesomycetozoea at the animal-fungal boundary. Phylogenetic analyses of R. seeb...

Abstract
A young Hindu male presented with painful swelling of left lower thigh for 6 months. The provisional diagnosis both clinically and radiologically was osteosarcoma. FNAC and biopsy proved the lesion to be a case of rhinosporidiosis. The present case is reported due to rare incidence of skeletal rhino...

Abstract
We regard as the Electron Dense Bodies (EDBs), and the cytoplasm of freshly prepared endospores or ones that were stored at 4 degrees. Slow-freezing at -20 degrees C, exposure to 10% formalin, or 0.1% sodium azide of the endospores abolished MTT-staining in both sites. Evan's Blue stained the EDBs a...

Abstract
These results indicate that an anti-rhinosporidial antibody response occurs in rhinosporidial patients, as well as in asymptomatic persons who were exposed to R. seeberi in the environment. Anti-R. seeberi antibody does not appear to be protective in rhinosporidiosis since appreciable titres were pr...

Congenitally T and B cell-deficient SCID mice and T cell-deficient NUDE mice, with BALB/c mice as immunologically normal controls, were inoculated with Rhinosporidium seeberi. At 3 and 16 weeks after inoculation, no evidence of rhinosporidiosis was detected. The reasons for the failure to establish...

We have amplified and sequenced nearly a full-length 18S small-subunit (SSU) ribosomal DNA (rDNA) sequence from R. seeberi. Using phylogenetic analysis, by parsimony and distance methods, of R. seeberi's 18S SSU rDNA and that of other eukaryotes, we found that this enigmatic pathogen of humans and a...
