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...

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...

this study represents an unusual case of mucormycosis localized in nasal cavity of a german shepherd dog. the patient was a 1-year-old male guard dog with unilateral nasal epistaxis, mucopurulent nasal discharge, sneezing and nose pawing. the dog had a history of head trauma about 2 months before admission, which was associated with mild self-limited epistaxis. initial nasal rhinoscopy showed s...

The performance of the Etest for itraconazole susceptibility testing of 50 isolates of filamentous fungi was assessed in comparison with the National Committee for Clinical Laboratory Standards (NCCLS) proposed standard microdilution broth method. The NCCLS method employed RPMI 1640 broth medium, and MICs were read after incubation for 48 h at 35 degrees C. Etest MICs were determined with RPMI ...

A 16-year-old diabetic patient developed Rhizopus pneumonia and was initially treated with amphotericin B for 7 days. Because of clinical deterioration of the patient, rifampin was added empirically. The patient improved clinically, and lung tissue removed surgically 8 weeks later showed no fungal elements by histopathological studies or by culture. An in vitro study of amphotericin B alone and...
