The anamorphs of the species of Pichia are various Candida species. The connection of specific Candida species with their corresponding Pichia teleomorphs is based on observation of the ascospores produced by the Candida isolate or more specifically, on the 28S gene sequence data. Pichia ohmeri has initially been isolated from cucumber brine and is commonly used in food industry for fermentation in pickles, rinds, and fruits. Clinically, Pichia has generally been considered to […]

Read MoreSynonyms Cerebral chromomycosis, chromoblastomycosis (in part), chromomycosis (in part), cladosporiosis, phaeomycotic cyst, phaeosporotrichosis, subcutaneous mycotic cyst. Definition Phaeohyphomycosis consists of a group of mycotic infections characterized by the presence of dematiaceous (dark-walled) septate hyphae and sometimes yeast or a combination of both in tissue. The hyphae may be short to elongate, distorted or swollen (toruloid hyphae), regularly shaped, or any combination of the above. The yeast when present will be variable in size and most of the time will show budding.

Read More(described by de Hoog in 1979) Taxonomic classification [1496] Kingdom: Fungi Division: Fungi Imperfecti Class: Blastomycetes Family: Phaeococcomycetaceae Genus: Phaeococcomyces Description and Natural Habitats Phaeococcomyces is a dematiaceous yeast that inhabits the soil and the plant material. The taxonomic position and the nomenclature for the Phaeococcomyces species appear variable in the literature. Due to a problem of nomenclature, the genus Phaeococcomyces has been established as a replacement for Phaeococcus. On the other hand, nutritional physiological data suggest that Phaeococcomyces exophialae is a yeast-like synanamorph of Exophiala spinifera [530, 531, 961]. Species The two widely accepted species of Phaeococcomyces are Phaeococcomyces […]

Read MoreOverview In spite of technical improvements in peritoneal dialysis, peritonitis continues to be the most common complication. Rates as high as one episode of peritonitis per year in every two dialysis patients have been reported [652]. Fungal peritonitis is relatively rare in comparison with bacterial peritonitis. However, it is a serious complication associated with not only important morbidity, but a high index of drop-out from chronic ambulatory peritoneal programs [319, 862, 2489]. Candida spp. are the most common fungal pathogens isolated in cases of fungal peritonitis. The frequency of Candida spp. in different series looking at this entity varies between […]
