13. Isolation of dematiaceous pathogenic fungi from a feed and seed warehouse.
In an epidemiological study, nine isolates of dematiaceous fungi were recovered from the interior of a local feed and seed warehouse. Sample sites include brick walls and floors. Air samples also were included. Samples were collected in saline and plated on Mycobiotic and Sabouraud agar. The nine dematiaceous fungi recovered from these samples were identifie

14. Dematiaceous fungal keratitis. Clinical isolates and management.
Clinical and laboratory features of 16 cases of keratitis that were caused by dematiaceous pigmented fungi are reported. Management, including the treatment of nine cases with Natamycin (Pimaricin), resulted in corneal healing in 14 cases, and therapeutic surgery in two cases.

15. Exoantigen test for differentiation of Exophiala jeanselmei and Wangiella dermatitidis isolates from other dematiaceous fungi.
Concentrated (25X) exoantigens of 105 isolates of pathogenic and saprophytic dematiaceous fungi and 3 isolates of Sporothrix schenckii were analyzed by the microimmunodiffusion method. The reagents used were nonadsorbed and adsorbed sera produced in New Zealand rabbits. One set of rabbits was immunized with soluble antigens of a 1-month-old culture of Exophi

16. APPLICATION OF FLUORESCENT–ANTIBODY PROCEDURES TO THE STUDY OF PATHOGENIC DEMATIACEOUS FUNGI I. : Differentiation of Cladosporium carrionii and Cladosporium Bantianum
Al-Doory, Yousef (Division of Laboratories and Research, New York State Department of Health, Albany) and Morris A. Gordon. Application of fluorescent-antibody procedures to the study of pathogenic dematiaceous fungi. I. Differentiation of Cladosporium carrionii and Cladosporium bantianum. J.

17. Evaluation of the API 20C yeast identification system for the differentiation of some dematiaceous fungi.
Ninety-seven isolates of Cladosporium spp., Exophiala spp., Fonsecaea spp., Lecythophora hoffmannii, Phaeoannellomyces werneckii, Phialophora spp., Wangiella dermatitidis, and Xylohypha bantiana were used to evaluate the API 20C Yeast Identification System for the differentiation of dematiaceous fungi. Using the API 20C system, we were able to distinguish mo

18. Selective medium for isolation of Fusarium species and dematiaceous hyphomycetes from cereals.
A selective medium containing 2 micrograms of dichloran per ml, 200 micrograms of chloramphenicol per ml, and 1.5% bacteriological peptone was developed for the isolation of Fusarium species and dematiaceous hyphomycetes from cereals. The medium, designated DCPA, was shown to select against species of Aspergillus, Penicillium, Cladosporium, and mucoraceous f

19. Application of Fluorescent-Antibody Procedures to the Study of Pathogenic Dematiaceous Fungi II. Serological Relationships of the Genus Fonsecaea
Gordon, Morris A. (New York State Department of Health, Albany), and Yousef Al-Doory. Application of fluorescent-antibody procedures to the study of pathogenic dematiaceous fungi. II. Serological relationships of the genus Fonsecaea. J. Bacteriol. 89:551–556. 1965.—The staining spectra of fluorescein-labeled antiglobulins to Fonsecaea compactum, F. derma

20. Resistance of some common fungi to gamma irradiation.
Ten species of fungi representing the genera Alternaria, Aspergillus, Caldosporium, Curvularia, Fusarium, and Penicillium were examined for their relative resistance to gamma irradiation from a 137Cs source. Inactivation doses for dematiaceous fungi in agar medium ranged from 0.6 to greater than 1.7 megarads, whereas those for moniliaceous fungi were less th

21. First report of subcutaneous phaeohyphomycosis of the foot caused by Phoma minutella.
Phoma minutella, a dematiaceous hyphomycete, was isolated to the exclusion of all other fungi from a subcutaneous inflammatory process on the foot of a farmer undergoing corticosteroid therapy for myasthenia gravis. Isolation was achieved on several nutrient media. Examination of stained smears and sections revealed dematiaceous fungal elements consistent wi

22. Exoantigen test for Cladosporium bantianum, Fonsecaea pedrosoi, and Phialophora verrucosa.
Exoantigens from 10-day-old cultures of 100 isolates of pathogenic and saprophytic dematiaceous fungi were analyzed by the exoantigen test. Antisera to Cladosporium bantianum ATCC 10958, Fonsecaea pedrosoi CDC AMO-B06, and Phialophora verrucosa CDC AMO-C12 were prepared in New Zealand rabbits immunized with soluble antigens from 1-month-old cultures. Absorbe

23. Fatal Endocarditis in a Neonate Caused by the Dematiaceous Fungus Phialemonium obovatum: Case Report and Review of the Literature
Phialemonium species are grouped by most authorities among the dematiaceous fungi. Like several other darkly pigmented fungi, they appear to be an emerging cause of human disease, especially in the immunocompromised host. As numbers of immunocompromised patients increase, the trend of unusual fungi emerging as new pathogens is set to continue. Previous exper

24. Analysis of genes coding for small-subunit rRNA sequences in studying phylogenetics of dematiaceous fungal pathogens.
Because of their ability to display yeast-like growth forms in various environmental conditions, dematiaceous (melanized) hyphomycetes of the form-genera Exophiala, Rhinocladiella, and Wangiella have been informally termed "black yeasts." Cladistic analysis of 1,050 bp of the genes coding for small-subunit rRNA (SSU rDNA) supported a close relationship among
