Currently, over 1200 species have been identified, infecting animals from nearly every phylum, including commercially important species such as honeybees and fish, as well as humans [ 1].
Its phylum includes movies as diverse in quality and mood as "Parenthood," "Hannah and Her Sisters" and "Once Around," and its closest Hollywood cousin is probably Jodie Foster's "Home for the Holidays".
The echinoderm phylum includes over 20,000 living species, including sea urchins, sea cucumbers and sea lilies.
The arthropod phylum includes all insects, spiders and millipedes, as well as crustaceans and sea spiders.
The Proteobacteria phylum includes many of the bacteria responsible for nitrogen fixation (Chen et al. 2003; Wang et al. 2015) and a wide variety of pathogens (Tsolis 2002).
Though most are small, this phylum includes the genus Ascaris, which can live in human intestines and grow over 30cm long.
The Actinobacteria phylum includes Corynebacterium and Propionibacterium; each genus was found in the ISS samples at a high level, which is "problematic," says Venkateswaran, because they both have species that are opportunistic pathogens.
There is no doubt that the phylum Nemertea is monophyletic (meaning that the phylum includes all and only descendants of one ancestor that was also a member of the phylum).
This phylum includes morels, a few mushrooms and truffles, unicellular yeasts (e.g., of the genera Saccharomyces, Kluyveromyces, Pichia, and Candida), and many filamentous fungi living as saprotrophs, parasites, and mutualistic symbionts.
The phylum includes pathogens (Mycobacterium spp., Nocardia spp., Corynebacterium spp., and Propionibacterium spp), nitrogen fixing symbionts (Frankia).
The phylum includes ∼100 000 described and living species.
