Molecular characterization of 18 species belonging to the genus Microsporum isolated from human and animal dermatophytosis was carried out by random amplification of polymorphic DNA (RAPD) and Southern hybridization analyses. All of these 18 Microsporum species showed different band patterns specific to each species in RAPD analysis. Southern hybridization analysis using C3 probe derived from a RAPD band from Arthroderma otae, teleomorph of M. canis, revealed distinct bands in 14 of the 18 Microsporum species but not in the other four species. The sizes of the hybridized bands of the 14 species were specific to each species, except three species (A. otae, M. equinum and M. ferrugineum) showing bands of the same size. These findings indicate that the RAPD and the Southern hybridization analyses could be effective to differentiate the species of Microsporum.

UI MeSH Term Description Entries
D008864 Microsporum A mitosporic Oxygenales fungal genus causing various diseases of the skin and hair. The species Microsporum canis produces TINEA CAPITIS and tinea corporis, which usually are acquired from domestic cats and dogs. Teleomorphs includes Arthroderma (Nannizzia). (Alexopoulos et al., Introductory Mycology, 4th edition, p305) Microsporon,Microsporons,Microsporums
D003881 Dermatomycoses Superficial infections of the skin or its appendages by any of various fungi. Skin Diseases, Fungal,Dermatomycosis,Dermatophyte Infection,Fungal Skin Diseases
D004271 DNA, Fungal Deoxyribonucleic acid that makes up the genetic material of fungi. Fungal DNA
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D001203 Ascomycota 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. Ascomycetes,Cochliobolus,Sclerotinia,Ascomycete,Ascomycotas,Sclerotinias
D015139 Blotting, Southern A method (first developed by E.M. Southern) for detection of DNA that has been electrophoretically separated and immobilized by blotting on nitrocellulose or other type of paper or nylon membrane followed by hybridization with labeled NUCLEIC ACID PROBES. Southern Blotting,Blot, Southern,Southern Blot
D019105 Random Amplified Polymorphic DNA Technique Technique that utilizes low-stringency polymerase chain reaction (PCR) amplification with single primers of arbitrary sequence to generate strain-specific arrays of anonymous DNA fragments. RAPD technique may be used to determine taxonomic identity, assess kinship relationships, analyze mixed genome samples, and create specific probes.
