Microascus manginii

Ciri dan struktur

Microascus manginii is a filamentous fungal species in the genus Microascus. It produces both sexual (teleomorph) and asexual (anamorph) reproductive stages known as M. manginii and Scopulariopsis candida, respectively. Several synonyms appear in the literature because of taxonomic revisions and re-isolation of the species by different researchers. M. manginii is saprotrophic and commonly inhabits soil, indoor environments and decaying plant material. It is distinguishable from closely related species by its light colored and heart-shaped ascospores used for sexual reproduction. Scopulariopsis candida has been identified as the cause of some invasive infections, often in immunocompromised hosts, but is not considered a common human pathogen. There is concern about amphotericin B resistance in S. candida. Colonies of M. manginii are pale, white and rapid growing. Growth is tolerant of cycloheximide and restricted at 37 °C. The vegetative hyphae are septate and appear glassy (hyaline). Ascomata are the sexual structures within which ascospores are produced in sacs called asci. The ascomata of M. manginii are spherical, smooth-walled, dark-brown to black and 100–175 μm in size. These fruiting bodies are also called perithecia because of their flask-like shape wherein asci grow at the base and an opening allows for the release of mature ascospores. They are also papillate with short cone-shaped projections at the opening, sessile, and rich in carbon. Perithecia manifest as small black dots organized in concentric rings. An incubation period of over two weeks may be necessary for the production of perithecia.

Habitat dan peran ekologis

M. manginii is a saprobic fungus. It has a worldwide distribution. It is often isolated from decaying plant material, soil and indoor environments, but also human skin and nails, dust, chicken litter, atmosphere, book paper and cheese, among other locations. Contaminated dust, soil and air samples are often found in North America and Europe. In Portugal, S. candida was identified as the most prevalent fungal species contaminating the air of three poultry slaughterhouses in 2016. Contamination with fungal pathogens was found on equipment used in physiotherapy clinics in Brazil, specifically electrodes and ultrasound transducers, S. candida was found on several contact electrodes.
