Originally thought to arise solely from Aspergillus infection, AFRS has been shown to involve dematiaceous fungi
, including Bipolaris, Curvularia, Exserohilum, and Alternaria spp, in 67% of cases.
Nevertheless, fungal infection of the eye is increasing, most notably by the species of Fusarium, Aspergillus, Candida, and dematiaceous fungi
in 20, dematiaceous fungi
in 3 and mixed infection (Aspergillus sp.
1989, "Physiological characteristics of environmental isolates of pathogenic dematiaceous fungi
," Mycoses, 32, pp.
The images can be searched in the following categories: algae, dematiaceous fungi
, dermatophytes, dimorphic fungi, filamentous bacteria, hyaline fungi, pnemnocystis, yeast and yeast-like organisms, and the zygomycetes.
One of the clinical syndromes associated with various species of dematiaceous fungi
increasingly being seen is phaeohyphomycosis.
In vitro fungicidal activities of voriconazole, itraconazole, and amphotericin B against opportunistic moniliaceous and dematiaceous fungi
melanigenum is considered among this group of dematiaceous fungi
(Bolignano and Criseo 2003).
In 1989, Robson et al (6) proposed the term allergic fungal sinusitis, because they identified dematiaceous fungi
instead of Aspergillus species in their patient.
His primary area of research deals with the pathogenesis of indoor mould related disease and the biosystematics and morphogenesis of pleomorphic dematiaceous fungi
that cause opportunistic mycotic infections.
It is caused by Aspergillus and dematiaceous fungi
Fungal organisms in the surgical specimens can be identified using Gomori methenamine-silver stain, but this does not aid in distinguishing the dematiaceous fungi
from Aspergillus or Zygomycetes species.
