Geotrichum klebahnii is a plant pathogen fungus.
Arabidopsis thaliana, the thale cress, mouse-ear cress or arabidopsis, is a small flowering plant native to Eurasia and Africa. A. thaliana is considered a weed; it is found by roadsides and in disturbed land.
Plant pathology is the scientific study of diseases in plants caused by pathogens and environmental conditions. Organisms that cause infectious disease include fungi, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants. Not included are ectoparasites like insects, mites, vertebrate, or other pests that affect plant health by eating of plant tissues. Plant pathology also involves the study of pathogen identification, disease etiology, disease cycles, economic impact, plant disease epidemiology, plant disease resistance, how plant diseases affect humans and animals, pathosystem genetics, and management of plant diseases.
Viili (Finnish) is a mesophilic fermented milk product found in Finland. This cultured milk snack resembles yoghurt and is the result of microbial action of lactic acid bacteria (LAB) and a surface-growing yeast-like fungus Geotrichum candidum present in milk, which forms a velvet-like surface on viili. In addition, most traditional viili cultures also contain yeast strains such as Kluveromyces marxianus and Pichia fermentans. The lactic acid bacteria identified in viili include the acid‐producing Lactococcus lactis subsp. lactis and L. l. cremoris as well as the aroma producers L. lactis subsp. lactis biovar diacetylactis and Leuconostoc mesenteroides. Among those mesophilic LAB strains, the slime-forming Lc. lactis subsp. cremoris produce a phosphate-containing heteropolysaccharide, named viilian. Viilian is similar to kefiran produced by kefir grains. The production of exopolysaccharides (EPS) by the strain forms the consistency character of viili and it has been claimed to have various functional benefits toward the rheological properties of milk products and the health improving potential.
The innate immune system is one of the two main immunity strategies found in vertebrates. The innate immune system is an older evolutionary defense strategy, relatively speaking, and is the dominant immune system response found in plants, fungi, insects, and primitive multicellular organisms.
Candida krusei is a budding yeast involved in chocolate production. Candida krusei is an emerging fungal nosocomial pathogen primarily found in the immunocompromised and those with hematological malignancies. It has natural resistance to fluconazole, a standard antifungal agent. It is most often found in patients who have had prior fluconazole exposure, sparking debate and conflicting evidence as to whether fluconazole should be used prophylactically. Mortality due to C. krusei fungemia is much higher than the more common C. albicans. Other Candida species that also fit this profile are C. parapsilosis, C. glabrata, C. tropicalis, C. guillermondii and C. rugosa.
Oidium is a genus of Deuteromycetes, where traditionally most anamorphs of the order Erysiphales are included. Most of them are plant pathogens causing different forms of powdery mildew, for example:
Verticillium dahliae is a fungal plant pathogen. It causes verticillium wilt in many plant species, causing leaves to curl and discolor. It may cause death in some plants. Over 400 plant species are affected by Verticillium complex.
Geotrichum is a genus of fungi found worldwide in soil, water, air, and sewage, as well as in plants, cereals, and dairy products; it is also commonly found in normal human flora and is isolated from sputum and feces. It was first described in 1809 by Johann Heinrich Friedrich Link.
Galactomyces candidum is a plant pathogen.
Geotrichum candidum is a fungus which is a member of the human microbiome, notably associated with skin, sputum and feces where it occurs in 25–30% of specimens. It is common in soil and has been isolated from soil collected around the world, in all continents.
Geotrichum candidum var. citri-aurantii is a plant pathogen. It is a common post harvest fungus disease of citrus known as "sour rot".
Phragmidium mucronatum is a plant pathogen that causes rose rust.
Dimorphic fungi are fungi that can exist in the form of both mold and yeast. This is usually brought about by change in temperature and the fungi are also described as thermally dimorphic fungi. An example is Talaromyces marneffei, a human pathogen that grows as a mold at room temperature, and as a yeast at human body temperature.
Geotrichosis is a mycosis caused by Geotrichum candidum.
Lida Holmes Mattman Ph.D. (1912–2008) was an immunologist. She graduated with a M.S. in Virology from the University of Kansas and a Ph.D. in Immunology from Yale University. Mattman taught in the fields of immunology, microbiology, bacteriology, virology and pathology for over 30 years. She worked at various schools and institutions including Harvard University, Howard Hughes Institute, Oakland University and Wayne State University. She was a Professor Emeritus in the Department of Biological Sciences at Wayne State University in Detroit where she was engaged in research and lecturing. She has served as President of the Michigan Branch of the American Society for Microbiology, as Chairman of the Medical Division of the Michigan Academy of Sciences, and held various offices in the local chapter of Sigma Xi.
In biology, a pathogen in the oldest and broadest sense, is any organism that can produce disease. A pathogen may also be referred to as an infectious agent, or simply a germ.
Fusarium langsethiae is a species of fungus in the family Nectriaceae. It is a suspected plant pathogen. This species was isolated from oats, wheat and barley kernels in several European countries. It resembles Fusarium poae, from which it differs by slower growth, less aerial mycelium and absence of odour. Its turnip-shaped or spherical conidia are borne in the aerial mycelium, whereas those of F. poae are produced on straight monophialides mostly in the aerial mycelium. It does not produce sporodochial conidia.
Heinrich Klebahn was a German mycologist and phytopathologist.
Verticillium klebahnii is a fungus often pathogenically inhabiting lettuce. It causes verticillium wilt in some plant species. It produces yellow-pigmented hyphae and microsclerotia, while producing abundant chlamydospores and resting mycelium. It is most closely related to V. tricorpus and V. isaacii.
Verticillium isaacii is a fungus inhabiting artichoke, spinach and lettuce, without necessarily being pathogenic. It causes verticillium wilt in some plant species. It produces yellow-pigmented hyphae and microsclerotia, while producing abundant chlamydospores and resting mycelium. It is most closely related to V. tricorpus and V. klebahnii.
