25. Allergic bronchopulmonary disease caused by Curvularia lunata and Drechslera hawaiiensis.
Three patients who developed bronchoceles caused by fungi other than Aspergillus sp are described. The first patient presented for investigation of a lesion at the right hilum on chest radiograph and a raised blood eosinophil count. A bronchogram showed complete block of the apical segmental bronchus which at operation was shown to be caused by inspissated m

26. Specific Oligonucleotide Primers for Identification of Cladophialophora carrionii, a Causative Agent of Chromoblastomycosis
Cladophialophora carrionii is one of the relatively common causative agents of chromoblastomycosis. We have developed the specific oligonucleotide primer set based on the internal transcribed spacer regions of ribosomal DNA for the rapid identification of this pathogen. PCR with this primer set amplified a 362-bp amplicon from C. carrionii strains. From othe

27. First report of involvement of Nodulisporium species in human disease.
Allergic fungal sinusitis is a common disease that results from a hypersensitivity reaction mounted by the host against fungi living in the paranasal sinuses. We have recently treated a patient with allergic fungal sinusitis due to a Nodulisporium species. This is the first description of a Nodulisporium species involved in human disease. The genus Nodulispo

28. In Vitro Fungicidal Activities of Voriconazole, Itraconazole, and Amphotericin B against Opportunistic Moniliaceous and Dematiaceous Fungi
The NCCLS proposed standard M38-P describes standard parameters for testing the fungistatic antifungal activities (MICs) of established agents against filamentous fungi (molds); however, standard conditions are not available for testing their fungicidal activities (minimum fungicidal or lethal concentrations [MFCs]). This study evaluated the in vitro fungist

29. Rapid Identification of the Genus Fonsecaea by PCR with Specific Oligonucleotide Primers
An oligonucleotide primer set based on internal transcribed spacer regions of ribosomal DNA for PCR which gives the amplicon for only the DNA from Fonsecaea species was designed. This set yielded an amplicon with 333 bp for all strains of Fonsecaea pedrosoi and Fonsecaea compacta examined but no amplicons for related dematiaceous fungi and pathogenic yeasts.

30. In Vitro Studies with Ambruticin, a New Antifungal Antibiotic
The in vitro antifungal inhibitory activities of ambruticin and of various antifungal drugs of choice against 190 fungal pathogens representative of the major human mycoses were compared using a modification of the ICS agar dilution technique. Ambruticin compared favorably with amphotericin B and miconazole when tested against the dimorphic pathogens Coccidi

31. Isolation of a Nodulisporium Species from a Case of Cerebral Phaeohyphomycosis
A fungal infection of the brain of a 55-year-old male patient is reported. The lesion and involved fungus were located exclusively in the right medial temporo-parietal region. The patient was successfully treated with surgical resection of the lesion and antifungal chemotherapy. Few pathogenic dematiaceous fungi exhibit neurotropism and can cause primary inf

32. Experience with the MicroSeq D2 Large-Subunit Ribosomal DNA Sequencing Kit for Identification of Filamentous Fungi Encountered in the Clinical Laboratory
Described herein is our experience with the MicroSeq D2 large-subunit rDNA sequencing kit for the identification of filamentous fungi encountered in the mycology laboratory at the Mayo Clinic. A total of 234 filamentous fungi recovered from clinical specimens were used in the evaluation. All were identified by using phenotypic characteristics as observed mac

33. Evaluation of proteolytic activity to differentiate some dematiaceous fungi.
A total of 123 isolates of Cladosporium spp., Exophiala spp., Fonsecaea spp., Lecythophora hoffmannii, Phaeoannellomyces werneckii, Phialophora spp., Wangiella dermatitidis, and Xylohypha bantiana were tested for proteolytic activity by using 26 different formulations of gelatin, milk, casein, and Loeffler media. Other physiological properties examined inclu

34. Morphologic and physiologic studies of three dematiaceous pathogens.
Uncertainty in identifying a dematiaceous mold from a human bronchial washing precipitated a study of Dactylaria gallopava (Cooke) Bhatt et Kendrick and its relationship to Scolecobasidium constrictum Abbott. Morphologic and physiologic studies were conducted with representative isolates and subcultures derived from the isolates used to prepare the type spec

35. Ribosomal DNA internal transcribed spacer analysis supports synonomy of Scedosporium inflatum and Lomentospora prolificans.
Scedosporium inflatum is a dematiaceous opportunistic pathogen originally described by D. Malloch and I.F. Salkin (Mycotaxon 21:247-255, 1984). However, E. Gueho and G. S. De Hoog (J. Mycol. Med. 118:3-9, 1991) recently suggested reducing this mold to synonomy with Lomentospora prolificans on the basis of their similar morphological and molecular characteris

36. In vitro studies with R 51,211 (itraconazole).
The in vitro activity of R 51,211 (itraconazole, accepted generic name; Janssen Pharmaceutica, Beerse, Belgium), a new orally active triazole, was compared with those of two existing orally active azoles, ketoconazole and BAY n 7133, and a topical agent, Ro 14-4767/002. An agar dilution procedure (Kimmig agar) was performed with 148 isolates of pathogenic fu
