| [opportunistic fungi as producers of gray colonies and mycetomata]. | madurella grisea mackinnon, ferrada and montemayor, 1949, is not the unique species that produces gray colonies and black-grained mycetomata. perhaps, it is not one species, because its grains and colonies may be confounded with those of several species that can be distinguished through their fertile structures. i take this opportunity to compare some characters of pyrenochaeta romeroi, phoma-phillosticta sp., chaetosphaeronema larense, pyrenochaeta mackinnonii, plendomus avramii and of another ... | 1979 | 385381 |
| studies on antigens from agents causing black grain eumycetoma. | culture filtrate and cellular antigens prepared from 14 agents which cause black grain eumycetoma were compared by double diffusion and immunoelectrophoresis. the fungal agents studied included five isolates of madurella grisea, two of madurella mycetomatis and a single isolate each of pyrenochaeta mackinnonii, pyrenochaeta romeroi, chaetosphaeronema (pseudochaetosphaeronema) larense, plenodomus avramii, phoma/phyllosticta, aureobasidium (exophiala) mansonii and leptosphaeria senegalensis. cross ... | 1989 | 2513382 |
| molecular identification of melanised non-sporulating moulds: a useful tool for studying the epidemiology of phaeohyphomycosis. | subcutaneous infections caused by melanised fungi have been increasingly reported among transplant patients, and these infections have the potential for blood and visceral dissemination. some moulds, such as mycelia sterilia, cannot grow and sporulate on different media, making their identification impossible by conventional methods. the fast and accurate identification of melanised fungi at the species level is important because species may have tropism to different organs and different suscept ... | 2013 | 23288581 |
| revision of agents of black-grain eumycetoma in the order pleosporales. | eumycetoma is a chronic fungal infection characterised by large subcutaneous masses and the presence of sinuses discharging coloured grains. the causative agents of black-grain eumycetoma mostly belong to the orders sordariales and pleosporales. the aim of the present study was to clarify the phylogeny and taxonomy of pleosporalean agents, viz. madurella grisea, medicopsis romeroi (syn.: pyrenochaeta romeroi), nigrograna mackinnonii (syn. pyrenochaeta mackinnonii), leptosphaeria senegalensis, l. ... | 2014 | 25737597 |
| redisposition of phoma-like anamorphs in pleosporales. | the anamorphic genus phoma was subdivided into nine sections based on morphological characters, and included teleomorphs in didymella, leptosphaeria, pleospora and mycosphaerella, suggesting the polyphyly of the genus. recent molecular, phylogenetic studies led to the conclusion that phoma should be restricted to didymellaceae. the present study focuses on the taxonomy of excluded phoma species, currently classified in phoma sections plenodomus, heterospora and pilosa. species of leptosphaeria a ... | 2013 | 24014897 |
