allergic fungal sinusitis complicated by fungal brain mass.a 36-year-old african american female with a 14-year history of allergic fungal sinusitis (afs) presented with progressive worsening headache, fevers, proptosis, and a large frontal lobe brain mass. after excisional biopsy, the non-invasive, dematiaceous mold, bipolaris australiensis, was identified. we review the epidemiology, etiology, pathophysiology, and clinical presentations of fungal sinusitis, as well as the complex management and multifaceted therapeutic modalities of afs.201020627788
molecular identification and antifungal susceptibility of curvularia australiensis, c. hawaiiensis and c. spicifera isolated from human eye infections.a reliable identification method was developed for three closely related curvularia species, which are frequently isolated from human keratomycoses. since the traditionally used morphological method and the increasingly used internal transcribed spacer (its)-based molecular method proved to be insufficient to discern c. australiensis, c. hawaiiensis and c. spicifera, other molecular targets, such as β-tubulin, translation elongation factor 1-α and the nuclear ribosomal intergenic spacer (igs), w ...201526345164
holadysenterine, a natural herbicidal constituent from drechslera australiensis for management of rumex dentatus.rumex dentatus l. is a problematic weed of wheat. bioassay-directed isolation of culture filtrates of a plant pathogenic fungus drechslera australiensis gave holadysenterine as the main herbicidal constituent against this weed of wheat. leaf disc bioassay showed that herbicidal activity of holadysenterine was comparable to that of synthetic herbicide 2,4-d. this is the first report of this herbicidal compound from the genus drechslera.201424364649
corneal ulcer due to a rare pleosporalean member of the genus bipolaris following cow tail injury to the eye: a case report and review of literature.aspergillus and fusarium are the most common fungi causing mycotic keratitis. injury to the eye with vegetable matter, cow tail injury, long-term use of topical steroids are some of the risk factors for mycotic keratitis. there are few case reports of keratitis caused by bipolaris. the human pathogenic species in the genus are bipolaris spicifera, bipolaris hawaiiensis, bipolaris papendorfii, and bipolaris australiensis. most commonly reported keratitis is caused by b. hawaiiensis, followed by b ...201728573998
diversity, molecular phylogeny, and bioactive potential of fungal endophytes associated with the himalayan blue pine (pinus wallichiana).in this study, we investigated the diversity of fungal endophytes associated with pinus wallichiana from the western himalayas, with emphasis on comparison of endophytic communities harbored by the stem and needle tissues of the host and their antimicrobial potential. a total number of 130 isolates, comprising of 38 different genera, were recovered from 210 fragments of the plant. among the isolated fungi, only a single isolate, tritirachium oryzae, belonged to the phylum basidiomycota whereas t ...201424563192
