| mycetoma | 1. A chronic infection involving the feet and characterised by the formation of localised lesions with tumefactions and multiple draining sinuses. The exudate contains granules that may be yellow, white, red, brown, or black, depending upon the causative agent. Mycetoma is caused by two principal groups of microorganisms: A. Actinomycotic mycetoma is caused by actinomycetes, including species of Streptomyces, Actinomadurae, and Nocardia. B. Eumycotic mycetoma is caused by true fungi, including species of Madurella, Exophiala, Pseudallescheria, Curvularia, Neotestudina, Pyrenochaeta, Aspergillus, Leptosphaeria, Plemodomus, Polycytella, Fusarium, Phialophora, Corynespora, Cylindrocarpon, Pseudochaetosphaeronema, Bipolaris, and Acremonium. Synonym: fungous foot, Madura boil, Madura foot, maduromycosis. 2. Any tumour with draining sinuses produced by filamentous fungi. (05 Mar 2000) |
| mycid | An allergic reaction to a remote focus of mycotic infection. Origin: G. Mykes, fungus, + -id (05 Mar 2000) |
| mycinamicin III O-methyltransferase | <enzyme> Catalyses the incorporation of the methyl group of s-adenosyl-l-methionine at the 3'' position of mycinamicin III; from micromonospora griseorubida; genbank d16097 Registry number: EC 2.1.1.- Synonym: mycf gene product, miii o-mtase (26 Jun 1999) |

| mycobacillin | <chemical> A cyclic polypeptide antibiotic isolated from culture filtrates of bacillus subtilis that acts as an antifungal agent. Pharmacological action: antibiotics, antifungal, antibiotics, peptide. Chemical name: Mycobacillin (12 Dec 1998) |
| mycobacillin synthetase | <enzyme> Requires ATP and mg; is inhibited by sulfhydryl reagents Registry number: EC 6.3.2.- (26 Jun 1999) |
| mycobacteria | <microbiology> Bacteria with unusual cell walls that are resistant to digestion, being waxy, very hydrophobic and rich in lipid, especially esterified mycolic acids. Staining properties differ from those of gram-negative and gram-positive organisms, being acid-fast. Many are intracellular parasites, causing serious diseases such as leprosy and tuberculosis. Cell wall has strong immunostimulating (adjuvant) properties due to muramyl dipeptide (MDP). Mycobacterium bovis causes tuberculosis in cattle, attenuated strain is Bacille Calmette-Guerin (BCG), used for immunisation. Mycobacterium leprae is the causative agent of leprosy. Mycobacterium microti is a mycobacterium that causes tuberculosis like disease in small rodents (Microtus microtus is the vole), will infect mice but not humans and is therefore much used as a laboratory model. Releases large amounts of cAMP which may inhibit lysosome phagosome fusion. Mycobacterium tuberculosis Is an obligate anaerobic nonmotile bacterium, causative agent of tuberculosis in humans. Lives intracellularly in macrophages. (18 Nov 1997) |
