Aspergillus oryzae, Penicillium citrinum and Rhizopus stolonifer isolated from Taif soil, Saudi Arabia could survive in a liquid medium containing up to 500 !lglml Zn. Aspergillus oryzae and Penicillium citrinum were more tolerant to zinc toxicity than Rhizopus stolonifer. The resistance and accumulation of zinc in the tested fungi were discussed according to tolerance index and zinc uptake in ...

A 46-year-old man with diabetes mellitus and cadaveric kidney transplant, maintained on a regimen of prednisone and azathioprine, developed a necrotizing pneumonia. The abscess cavity became secondarily infected with Rhizopus and was cured by surgical resection. Secondary invasion of an abscess cavity by Rhizopus and the successful surgical treatment of pulmonary phycomycosis in an immunosuppre...

We present a case of rhino-orbitary mucormycosis which progressed despite liposomal amphotericin and early surgical debridement. Combined echinocandin and high dose liposomal amphotericin, repeated debridement, prolonged therapy with hyperbaric oxygen and continued therapy with posaconazole, along with strict diabetic control, allowed cure without disfigurement.

The filamentous fungus Rhizopus delemar naturally accumulates relatively high amounts of fumarate. Although the culture conditions that increase fumarate yields are well established, the network underlying the accumulation of fumarate is not yet fully understood. We set out to increase the knowledge about fumarate accumulation in R. delemar. To this end, we combined a transcriptomics and proteo...

Soft rot in apple caused by Rhizopus oryzae was found for the first time in Korea. A detailed description of the specimen is given along with its internal transcribed spacer rDNA sequence. The fungus was identified as Rhizopus oryzae based on the mycological characteristics, molecular data, and pathogenicity testing.

Occupational asthma in coal miners is hardly recognised. A report is presented of a coal miner whose clinical picture suggested a respiratory allergy which occurred only in the mine where he worked. Serum specific IgE levels, skin tests, and bronchial provocation tests with different commercial extracts showed sensitisation to Rhizopus nigricans. Rhizopus spp were found inside the mine, as demo...

The microbial conversion of zearalenone by various species of fungi was studied. Among them, Rhizopus sp. was the sole fungus which produced a new metabolite from zearalenone in addition to alpha- and beta-zearalenol. The structure of the new metabolite was determined to be zearalenone 4-beta-D-glucopyranoside on the basis of mass, infrared, and nuclear magnetic resonance spectroscopies. The re...

mucormycosis is an invasive fungal infection caused by filamentous fungi of the mucoraceae family. the genera most commonly responsible are mucor or rhizopus. the disease occurs mostly in association with diabetic ketoacidosis. mucormycosis has an extremely high death rate even when aggressive surgery is done. death rates range from 25-85% depending on the body area involved.a case of rhinocere...
