The term dimorphic is commonly used for fungi that can grow both as yeast and filamentous cells, however many of these dimorphic fungi actually can grow in more than these two forms. Dimorphic is thus often used as a general reference for fungi being able to switch between yeast and filamentous cells, but not necessary limiting more shapes. [4] [a]
For most of the 20th century, the classification of R. seeberi was unclear (being considered either a fungus or a protist), but it was shown to be part of a group called the Mesomycetozoea [8] [9] (or "DRIP clade"), [10] which includes a number of well-known fish pathogens such as Dermocystidium and Sphaerothecum destruens.
Aspergillus dimorphicus is a species of fungus in the genus Aspergillus. It is from the Cremei section. [2] The species was first described in 1969. [1] It has been reported to produce wentilactones. [3]
Mucor indicus is among the most important members of zygomycetes fungi. This dimorphic fungus is capable of production of several valuable products. Some strains of the fungus have been isolated from the traditional Indonesian food tempeh. M. indicus is nowadays used for production of several homemade food and beverages especially in Asia.
Viewing the fungi under a microscope, Micheli was reminded of the shape of an aspergillum (holy water sprinkler), from Latin spargere (to sprinkle), and named the genus accordingly. [ 2 ] [ 3 ] Aspergillum is an asexual spore-forming structure common to all Aspergillus species; around one-third of species are also known to have a sexual stage ...
The dimorphic Basidiomycota with yeast stages and the pleiomorphic rusts are examples of fungi with anamorphs, which are the asexual stages. Some Basidiomycota are only known as anamorphs. Many are called basidiomycetous yeasts, which differentiates them from ascomycetous yeasts in the Ascomycota. Aside from yeast anamorphs and uredinia, aecia ...
Like humans and other animals, fish suffer from diseases and parasites. Fish defences against disease are specific and non-specific. Fish defences against disease are specific and non-specific. Non-specific defences include skin and scales, as well as the mucus layer secreted by the epidermis that traps microorganisms and inhibits their growth.
Fungi are hypothesized to contribute to phytoplankton population cycles and the biological carbon pump and are active in the chemistry of marine sediments. Many fungi have been identified as commensals or pathogens of marine animals (e.g., corals and sponges), plants, and algae. Despite their varied roles, remarkably little is known about the ...
