A kingdom of eukaryotic, heterotrophic organisms that live parasitically as saprobes, including MUSHROOMS; YEASTS; smuts, molds, etc. They reproduce either sexually or asexually, and have life cycles that range from simple to complex. Filamentous fungi, commonly known as molds, refer to those that grow as multicellular colonies.
A genus of mitosporic fungi containing about 100 species and eleven different teleomorphs in the family Trichocomaceae.
Reproductive bodies produced by fungi.
The presence of bacteria, viruses, and fungi in the air. This term is not restricted to pathogenic organisms.
A large and heterogenous group of fungi whose common characteristic is the absence of a sexual state. Many of the pathogenic fungi in humans belong to this group.
A group of antibiotics that contain 6-aminopenicillanic acid with a side chain attached to the 6-amino group. The penicillin nucleus is the chief structural requirement for biological activity. The side-chain structure determines many of the antibacterial and pharmacological characteristics. (Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed, p1065)
A class of organic compounds containing four or more ring structures, one of which is made up of more than one kind of atom, usually carbon plus another atom. The heterocycle may be either aromatic or nonaromatic.
The body of a fungus which is made up of HYPHAE.
Anaerobic degradation of GLUCOSE or other organic nutrients to gain energy in the form of ATP. End products vary depending on organisms, substrates, and enzymatic pathways. Common fermentation products include ETHANOL and LACTIC ACID.
Deoxyribonucleic acid that makes up the genetic material of fungi.
A mycotoxin with antibiotic and carcinogenic activity produced by various strains of PENICILLIUM and ASPERGILLUS. It has been found in tobacco, sausages, and corn.
The presence of bacteria, viruses, and fungi in food and food products. This term is not restricted to pathogenic organisms: the presence of various non-pathogenic bacteria and fungi in cheeses and wines, for example, is included in this concept.
Compounds that differ from COUMARINS in having the positions of the ring and ketone oxygens reversed so the keto oxygen is at the 1-position of the molecule.
An antifungal agent used in the treatment of TINEA infections.
An enzyme that catalyzes the activation of sulfate ions by ATP to form adenosine-5'-phosphosulfate and pyrophosphate. This reaction constitutes the first enzymatic step in sulfate utilization following the uptake of sulfate. EC 2.7.7.4.
A metabolite in the principal biochemical pathway of lysine. It antagonizes neuroexcitatory activity modulated by the glutamate receptor, N-METHYL-D-ASPARTATE; (NMDA).
An order of fungi in the phylum ASCOMYCOTA characterized by the presence of well defined peridia and cleistothecial asci. Notable anamorphs (mitosporic forms) of Eurotiales include PENICILLIUM and ASPERGILLUS.
A two-person sport in which the fists are skillfully used to attack and defend.
Software used to locate data or information stored in machine-readable form locally or at a distance such as an INTERNET site.
Those physicians who have completed the education requirements specified by the American Academy of Family Physicians.
Organized activities related to the storage, location, search, and retrieval of information.
A measure of the amount of WATER VAPOR in the air.
Works containing information articles on subjects in every field of knowledge, usually arranged in alphabetical order, or a similar work limited to a special field or subject. (From The ALA Glossary of Library and Information Science, 1983)
A plant genus of the family RUTACEAE. They bear the familiar citrus fruits including oranges, grapefruit, lemons, and limes. There are many hybrids which makes the nomenclature confusing.
Echinoderms having bodies of usually five radially disposed arms coalescing at the center.
A genus of STARFISH in the family Asteriidae. One species, Asterias rubens, is the most common in the north-east Atlantic region.
CHOLESTANES substituted with any number of keto groups.
Steroids with methyl groups at C-10 and C-13 and a branched 8-carbon chain at C-17. Members include compounds with any degree of unsaturation; however, CHOLESTADIENES is available for derivatives containing two double bonds.
A nutritious food consisting primarily of the curd or the semisolid substance formed when milk coagulates.
A plant family of the order Orchidales, subclass Liliidae, class Liliopsida (monocotyledons). All orchids have the same bilaterally symmetrical flower structure, with three sepals, but the flowers vary greatly in color and shape.
A plant genus of the family FABACEAE. The common name of indigo also refers to Baptisia or Amorpha genera (FABACEAE).
An endocellulase with specificity for the hydrolysis of 1,3-beta-D-glucosidic linkages in 1,3-beta-D-glucans including laminarin, paramylon, and pachyman.
A plant genus of the family ASTERACEAE. Members contain CHALCONE, helichrysetin, arenarin, and flamin.
Provision of physical and biological barriers to the dissemination of potentially hazardous biologically active agents (bacteria, viruses, recombinant DNA, etc.). Physical containment involves the use of special equipment, facilities, and procedures to prevent the escape of the agent. Biological containment includes use of immune personnel and the selection of agents and hosts that will minimize the risk should the agent escape the containment facility.
A plant genus of the family ARACEAE. The name derived from ar (fire in Arabic) due to the irritating sap. Flower is a spathe.
A phylum of fungi which have cross-walls or septa in the mycelium. The perfect state is characterized by the formation of a saclike cell (ascus) containing ascospores. Most pathogenic fungi with a known perfect state belong to this phylum.

The longterm manifestations of WEATHER. (McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)
A complex sulfated polymer of galactose units, extracted from Gelidium cartilagineum, Gracilaria confervoides, and related red algae. It is used as a gel in the preparation of solid culture media for microorganisms, as a bulk laxative, in making emulsions, and as a supporting medium for immunodiffusion and immunoelectrophoresis.
