Blastomyces dermatitidis is the causal agent of blastomycosis, a potentially very serious disease that typically begins with a characteristically subtle pneumonia-like infection that may progress, after 1–6 months, to a disseminated phase that causes lesions to form in capillary beds throughout the body, most notably the skin, internal organs, central nervous system and bone marrow.
The rice false smut pathogen, Ustilaginoidea virens, invades through a small gap at the apex of a rice spikelet before heading. [7] The primary source of infection is the presence of chlamydospores in the soil. [8]
Mycoplasma laboratorium or Synthia [b 1] refers to a synthetic strain of bacterium. The project to build the new bacterium has evolved since its inception. Initially the goal was to identify a minimal set of genes that are required to sustain life from the genome of Mycoplasma genitalium, and rebuild these genes synthetically to create a "new ...
The fruit bodies are semicircular to fan-shaped brackets that measure up to 8 cm (3 in) broad by 10 cm (4 in) wide, with a thickness of 0.5–2 cm (0.2–0.8 in). The upper surface is initially white before aging to yellowish or grayish, and has a texture ranging from smooth to tomentose.
A drawing on the lower side of the sporocarp of G. applanatum. A peculiarity of this fungus lies in its use as a drawing medium for artists. [14] When the fresh white pore surface is rubbed or scratched with a sharp implement, dark brown tissue under the pores is revealed, resulting in visible lines and shading that become permanent once the fungus is dried.
The albino laboratory rat with its red eyes and white fur is an iconic model organism for scientific research in a variety of fields. Laboratory rats or lab rats are strains of the rat subspecies Rattus norvegicus domestica (Domestic Norwegian rat) which are bred and kept for scientific research.
Trametes versicolor – also known as Coriolus versicolor and Polyporus versicolor – is a common polypore mushroom found throughout the world. Meaning 'of several colors', versicolor accurately describes this fungus that displays a unique blend of markings.
The mushroom has a broad, fan or oyster-shaped cap spanning 2–30 centimetres (3 ⁄ 4 – 11 + 3 ⁄ 4 inches); [3] natural specimens range from white to gray or tan to dark-brown; the margin is inrolled when young, and is smooth and often somewhat lobed or wavy.
