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 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 کاملA new antibiotic CJ-17,665 from Aspergillus ochraceus.
A new antibiotic, CJ-17,665 (I) was isolated from the fermentation broth of Aspergillus ochraceus, CL41582. It inhibits growth of multi-drug resistant Staphylococcus aureus, Streptococcus pyogenes, and Enterococcus faecalis, with MICs of 12.5, 12.5 and 25 microg/ml, respectively. The structure contains a diketopiperazine and an indole N-oxide moiety that is unusual in natural products.
متن کاملRapid method for preparing cell-free extracts of Aspergillus ochraceus.
A rapid method for preparing cell-free extracts of Aspergillus ochraceus was developed. Mycelial mats were prefrozen in liquid nitrogen, ground to a fine powder in a cold mortar, and homogenized in an all-glass mechanical homogenizer. This method provided preparations averaging 43.0 mg of protein per g of mycelium (wet weight). The method was fast, efficient, and did not subject the extract ...
متن کاملAislamiento y caracterización de vcp1, un nuevo fago filamentoso de vibrio cholerae O139
We found a novel filamentous phage, designated VCP1, in strain SG25-1 of Vibrio cholerae O139. The 7543 bases nucleotide sequence of the phage genome was determined. The analysis of the nucleotide sequence revealed that VCP1 had a distinctive region of 775 nucleotides with an unknown origin and function which did not show homology with any entry in the databases, and a conserved region with sim...
