screening of middle ear effusion for the common sinus pathogen bipolaris.recently, a third of middle ear effusions have been shown to harbor fungal dna by polymerase chain reaction (pcr). this suggests that fungi, in addition to being an important sinus pathogen, may also play an important role in acute and serous otitis media. bipolaris is an important sinus pathogen whose role in infections of the ear is unknown. in this study, we assessed if bipolaris dna was present in 19 middle ear effusions that were pcr positive for the presence of fungi. primer pair specific ...200312582783
virulence of curvularia in a murine model.we have evaluated the virulence of two clinically relevant species of curvularia; curvularia spicifera and c. hawaiiensis, using an experimental model of disseminated infection in immunocompromised mice. several inocula were tested over a range 1 × 10(3) -1 × 10(6) colony-forming units/animal. both species had a similar behaviour, producing a high mortality. tissue burden and histopathology studies demonstrated that lung was the organ most affected.201323437873
disseminated phaeohyphomycosis in a dog.phaeohyphomycosis is a rare but emerging disease caused by dematiaceous fungi. here we describe the case of an immunosuppressed dog with disseminated phaeohyphomycosis secondary to bipolaris spicifera infection. regionally extensive infiltration of the paw pads, skin, myocardium, liver, renal interstitium and diaphragm was identified on histopathology. candida glabrata and fusarium oxysporum were also cultured from multiple sites post-mortem. the dog was treated with fluconazole, itraconazole, t ...201728275534
in vitro activities of isavuconazole against opportunistic filamentous and dimorphic fungi.the in vitro activity of isavuconazole was compared to those of amphotericin b, fluconazole, itraconazole, voriconazole, posaconazole, and ravuconazole against 300 clinical isolates of pseudallescheria boydii, paecilomyces lilacinus, fusarium spp., bipolaris spicifera, curvularia lunata, alternaria alternata, exophiala spp., rhizopus arrhizus, mucor circillenoides, absidia corymbifera, blastomyces dermatitidis, histoplasma capsulatum and coccidioides posadasii. mics were determined by a broth ma ...200919101837
cerebral phaeohyphomycosis caused by bipolaris spicifera after heart transplantation.phaeohyphomycosis is an increasingly recognized cause of brain abscess in both immunocompetent and immunocompromised hosts. we report a case of cerebral phaeohyphomycosis in a 55-year-old male heart transplant recipient caused by bipolaris spicifera. we review the literature regarding the pathogenesis, epidemiology, diagnosis, and management of infections with dematiaceous fungi.201121323827
nonpathogenic, environmental fungi induce activation and degranulation of human eosinophils.eosinophils and their products are probably important in the pathophysiology of allergic diseases, such as bronchial asthma, and in host immunity to certain organisms. an association between environmental fungal exposure and asthma has been long recognized clinically. although products of microorganisms (e.g., lipopolysaccharides) directly activate certain inflammatory cells (e.g., macrophages), the mechanism(s) that triggers eosinophil degranulation is unknown. in this study we investigated whe ...200516210651
allergic fungal sinusitis caused by bipolaris spicifera and schizophyllum commune.there have been very few reports in japan of patients with allergic fungal sinusitis (afs). we describe two cases caused by bipolaris spicifera and schizophyllum commune. the patients were a 70-year-old male (case 1) and a 55-year-old female (case 2). both presented with nasal obstruction and purulent nasal discharge. ct scans revealed each to have a soft tissue mass extending from the ethmoid sinus to the sphenoid sinus. in addition, pathological studies on the contents of the paranasal sinuses ...200717710626
disseminated infection by bipolaris spicifera in an immunocompetent subject.we report a case of disseminated infection due to bipolaris spicifera in an immunocompetent male. histopathological studies of lymph node, lung, and liver biopsy specimens showed a dark pigmented, granular fungal structure inside the granuloma. the disease was accompanied by the unusual feature of positive lupus anticoagulant in serum and low-density areas expanding along the portal vein in the liver. the disease responded to combination therapy with intravenous amphotericin b and voriconazole, ...200818415844
isolation and molecular identification of keratinophilic fungi from public parks soil in shiraz, iran.keratinophilic fungi are an important group of fungi that live in soil. the aim of this study was to isolate and identify keratinophilic fungi from the soil of different parks in shiraz.201323956993
fungitoxicity of organic extracts of ocimum basilicum on growth and morphogenesis of bipolaris species (teleomorph cochliobolus).this study aimed at evaluating the inhibitory effects of various organic extracts of ocimum basilicum against some species of bipolaris and cochliobolus with gc-ms and hplc analysis.201728718990
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
exploring the potentials of lysinibacillus sphaericus za9 for plant growth promotion and biocontrol activities against phytopathogenic fungi.there is an ongoing hunt for biologically active compounds that can combat phytopathogenic fungi and improve plant growth without causing any hazards to the environment. consequently the present study aims at deciphering the plant growth promotion and antifungal capability of lysinibacillus sphaericus za9. the bacterium was previously isolated and identified in our laboratory from maize rhizosphere using 16s rrna gene sequencing. the test bacterium l. sphaericus za9 was found to produce high qua ...201728861045
development of a multilocus sequence typing system for medically relevant bipolaris species.multilocus sequence typing (mlst) is the gold standard genotyping technique for many microorganisms. this classification approach satisfies the requirements for a high-resolution, standardized, and archivable taxonomic system. here, we describe the development of a novel mlst system to assist with the investigation of an unusual cluster of surgical site infections caused by bipolaris spp. in postoperative cardiothoracic surgery (pocs) patients during january 2008 to december 2013 in the southeas ...201526202112
unilateral renal phaeohyphomycosis due to bipolaris spicifera in an immunocompetent child - rare case presentation and review of literature.phaeohyphomycosis refers to infections caused by phaeoid fungi that can have an aggressive course in normal hosts. we report a case of left-sided renal phaeohyphomycosis due to bipolaris spicifera in a 7-year-old immunocompetent male child. he presented with fever, dysuria, nausea, vomiting and flank pain. examination revealed tenderness at the left costovertebral angle. histological examination and culture of biopsy from left kidney and blood yielded the fungal pathogen bipolaris spicifera. his ...201526058420
