Aspergillus nodules in chronic granulomatous disease attributable to Aspergillus ochraceus
Aspergillus ochraceus is a rare pulmonary pathogen. A 39 year old male with COPD and chronic granulomatous disease presented with severe breathlessness and recurrent infections. CT scan demonstrated multiple pulmonary nodules diagnosed as chronic pulmonary aspergillosis. The patient's sputum grew Aspergillus ochraceus thrice over 6 months, alongside positive Aspergillus IgG and serum galactoman...
متن کاملXylanase production by a newly isolated Aspergillus niger SS7 in submerged culture.
Xylanase production by a newly isolated Aspergillus niger SS7 was studied in submerged culture. The optimum initial pH for xylanase production was found to be 7.0. Different agricultural and industrial wastes were evaluated for their ability to induce xylanase production by this isolate. The best xylanase production (293.82 IU/ml) was recorded at 3% (w/v) corn cob hulls after 120 h of incubatio...
متن کاملOchratoxin production by the Aspergillus ochraceus group and Aspergillus alliaceus.
Ochratoxin A is a toxic and carcinogenic fungal secondary metabolite; its presence in foods is increasingly regulated. Various fungi are known to produce ochratoxins, but it is not known which species produce ochratoxins consistently and which species cause ochratoxin contamination of various crops. We isolated fungi in the Aspergillus ochraceus group (section Circumdati) and Aspergillus alliac...

متن کاملOccurrence of fungi and cytotoxicity of the species: Aspergillus ochraceus, Aspergillus niger and Aspergillus flavus isolated from the air of hospital wards.
OBJECTIVES The basic care requirement for patients with weakened immune systems is to create the environment where the risk of mycosis is reduced to a minimum. MATERIAL AND METHODS Between 2007 and 2013 air samples were collected from various wards of a number of hospitals in Kraków, Poland, by means of the collision method using MAS-100 Iso MH Microbial Air Sampler (Merck Millipore, Germany)...
