Abstract A description is provided for Trichophyton violaceum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Primarily a pathogen of man (causing mycoses). Also recorded from buffalo, cat, cattle, dog and mouse (RMVM 6, 3187; 10, 505). The cat, dog, guineapig, monkey and mouse have been infected experimentally. The horse, fowl and pigeon have been implicated as hosts of T. violaceum. DISEASE: Ringworm (dermatophytosis, tinea). The scalp (tinea capitis), beard (tinea barbae), body (tinea corporis) and nails (tinea unguium, onychomycosis) may be infected. Infected hairs show an endothrix type of invasion and do not fluoresce under Wood's light. The hairs may break and curl producing 'black dots' on the scalp (also sometimes produced by other endothrix Trichophyton species). Inflammatory lesions (occasionally with the development of kerion), scarring and alopecia and, occasionally, favus-like lesions may occur. Infections of the subcutaneous tissues, lymph nodes, brain, bones and other internal tissues have been reported (RMVM 3, 1441; 4, 716; 9, 677; 11, 708; 12, 1847; 13, 961, 1572). GEOGRAPHICAL DISTRIBUTION: Worldwide. A dominant cause of scalp ringworm in S. and E. Europe, the Middle East, N. Africa, parts of Central and E. Africa, S. Africa and Asia (RMVM 10, 602; 13, 1558).

Abstract: Dermatophytosis is a disorder of tissues with keratinized ephithelia e. g. stratum corneum of epidermis, hair, and nails, caused by dermatophyte fungi from arthrodermataceae family. This family has more than 40 species divided into three genera: Epidermophyton, Microsporum, and Trichophyton. The distribution of dermatophytosis is based on its location: tinea capitis, tinea barbae, tinea cruris, tinea pedis et manum, tinea unguium, and tinea corporis. This study aimed to obtain the profile of dermatophytosis classified by location, age, gender, job and therapy at the Dermatovenerology Clinic of Prof. Dr. R. D. Kandou Hospital Manado during the period of January-December 2013. The results showed that of 4,099 skin disease cases in 2013, there were 153 (3.7%) cases of dermatophytosis with the most frequent found was tinea cruris (35.3%), the age group was 45-64 years old (32.7%), most patients were female (60.8%), commonly housewife (22.9%), and the most treatmen tused was topical therapy (68.6%).Keywords: dermatophyte, dermatophytosis, tinea Abstrak: Dermatofitosis merupakan penyakit pada jaringan yang mengandung zat tanduk, seperti stratum korneum pada epidermis, rambut dan kuku, yang disebabkan oleh jamur dermatofita dari famili arthrodermataceae.

Abstract A description is provided for Nannizzia incurvata. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Recorded only from man and dog (but see NOTES). Guinea-pigs have been experimentally infected. DISEASE: Ringworm (dermatophytosis, tinea). Nannizzia incurvata is present in soil and apparently only rarely a cause of disease. In man the scalp (tinea capitis) and glabrous skin (tinea corporis) may be infected. Skin lesions are inflammatory but details of known scalp infections are not available. In experimental inoculations of guineapigs (Rdzanek, pers. comm.) N. incurvata was intermediate between N. gypsea and N. fulva in virulence, the reaction varying from negative to strongly inflammatory. Ectothrix hyphae breaking up into large arthrospores were seen on some hairs, and infected hairs did not fluoresce under Wood's light. GEOGRAPHICAL DISTRIBUTION: Asia (India), Europe (Czechoslovakia, Great Britain and Ireland, Germany, Netherlands, Poland); U.S.A. (Tenn.); N. incurvata is probably of world-wide distribution in the soil.

Nannizzia Persicolor

Abstract A description is provided for Nannizzia persicolor. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: The primary hosts of N. persicolor are various species of voles (particularly the bank vole, Clethrionomys glareolus), on which it usually occurs without visible signs of infection (RMVM 6, 927), males being somewhat more frequently infected than females (RMVM 12, 157; 14, 1479). It is also sometimes carried on the fur of other rodents (recorded from pipistrelle bat (RMVM 5, 2201), hamster (RMVM 12, 157), deer mouse (RMVM 14, 134), wood mouse (RMVM 6, 926), common shrew (RMVM 6, 926) and weasel (RMVM 7, 63)) without apparent infection, and has been isolated from a healthy pony (RMVM 8, 446). Ringworm caused by this species has also been recorded in the dog (RMVM 2, 1650; 6, 1920; 12, 1854), horse (RMVM 6, 3213) and man. The epidemic in guineapigs in Tunisia (RMVM 5, 498) was probably not due to N. persicolor (RMVM 5, 2201). The guineapig, monkey, mouse and rabbit have been infected experimentally (RMVM 1, 1739; 10, 595). It has also been isolated on a few occasions from soil (RMVM 11, 95). DISEASE: Ringworm (dermatophytosis, tinea). In the vole the most constantly infected site is the tail, which may show varying degrees of scaling and hair loss, symptoms also sometimes found on fungus-free tails (6, 927); lesions have been found only rarely on other sites. In man infection occurs mainly on exposed parts of the glabrous skin, i.e. on the face, hands (tinea manuum) and forearms and lower legs (tinea corporis). Infections of the beard area (tinea barbae), nails (tinea unguium), scalp (tinea capitis) and feet (tinea pedis) have also been recorded [see NOTES]. Lesions are scaling and usually mildly to moderately erythematous. More inflammatory lesions may occur and kerion formation has been reported in a few instances. Hair is not invaded in vivo. GEOGRAPHICAL DISTRIBUTION: Possibly worldwide; N. persicolor has been recorded widely in Europe and rarely from N. America (Canada, USA), S. America (Brazil, Uruguay), Africa (Tunisia, S. Africa) and Asia (India, Israel) [see NOTES].

Abstract A description is provided for Epidermophyton floccosum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Primarily a pathogen of man (causing mycoses). Also recorded from dog (RMVM 6, 1920) and mouse (RMVM 6, 639). Animal inoculation is rarely successful; the guineapig (RMVM 14, 804), monkey (RMVM 1, 182) and the chorio-allantoic membrane of the hen's egg (RMVM 2, 1676; 4, 82) have been infected experimentally. DISEASE: Ringworm (dermatophytosis, tinea). The groin (tinea cruris, eczema marginatum, dobie itch) and feet (tinea pedis) are most frequently infected. The body (tinea corporis), hands (tinea manuum) and nails (onychomycosis, tinea unguium) may also be infected. Infections of the scalp (tinea capitis) are rare and the hair is never invaded in vivo. Skin lesions are scaling and erythematous, well-marginated with minute vesicopapules in the border. GEOGRAPHICAL DISTRIBUTION: Worldwide.

Abstract A description is provided for Microsporum canis. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Primarily a pathogen of the cat and dog, frequently transmitted to man. Also recorded from the chimpanzee, chinchilla, fox, lion, monkey, pig, rabbit, sheep and tiger. Experimental animals are susceptible to infection. DISEASE: Ringworm (dermatophytosis, tinea). Infected hairs and animal claws usually fluoresce bright green under Wood's light and hairs are surrounded by ectothrix sheaths of small spores in a mosaic arrangement. In cats the lesions are usually inconspicuous. They may occur on any part of the body, but particularly the face and paws, and the whiskers and claws may be involved. In dogs infection is more noticeable, and is characterized by small circular areas of scaling and alopecia, sometimes with oedema and crust formation, on any part of the body. The claws may also be infected. Infections in dogs have a well defined seasonal incidence with a peak in Oct. -Feb., but the incidence in cats is poorly defined (Kaplan & Ivens, Sabouraudia 1: 91-102, 1961). In man the scalp (tinea capitis), glabrous skin (tinea corporis), and rarely the beard (tinea barbae), foot (tinea pedis) and nails (tinea unguium, onychomycosis) may be infected (mycoses). Children are most susceptible, particularly to scalp infection which is very rare in adults. Scalp lesions are scaling, inflammatory areas containing broken hairs or with total hair loss. Pustulation and kerion formation are not uncommon. Skin lesions are circinate, with a scaling centre and vesicular border. Kligman (RMVM 1, 2510; 2, 2484) studied the pathogenesis of tinea capitis caused by M. canis. GEOGRAPHICAL DISTRIBUTION: Africa (Algeria, Angola, Cape Verde Islands, Egypt, French W. Africa, Sahara, Tunisia, Union of S. Africa); Asia (Ceylon, India, Philippines, Turkey); Australasia & Oceania (Australia (N.S.W.), New Zealand); Europe, North America, Central America and West Indies (Costa Rica, Cuba, Guatemala, Mexico, Panama, Puerto Rico); South America (Argentina, Brazil (south of Pernambuco), Chile, Colombia, Ecuador, Peru, Uruguay, Venezuela).

Objectivos: Avaliar a prevalência das micoses superficiais, agentes etiológicos envolvidos e características epidemiológicas da população da consulta de Dermatologia do Hospital de Braga, observada por dermatofitia, nos últimos 11 anos; analisar a distribuição de espécies em relação ao grupo etário e área cutânea envolvida; comparar os resultados com estudos anteriores referentes à mesma área geográfica.Material e Métodos: Exame micológico directo e cultura de 5825 amostras colhidas em doentes observados na consulta do Serviço de Dermatologia do Hospital de Braga, entre Janeiro de 1999 e Dezembro de 2009, com suspeita clínica de dermatofitia.Resultados: Durante o período em estudo, das 5825 colheitas realizadas em doentes com suspeita clínica de infecção fúngica, foi identificada a presença de dermatófito em 1143 (19,6%). A apresentação clínica da infecção por dermatófito mais frequente foi a tinea corporis (44,8%). Globalmente, o agente etiológico mais frequentemente isolado foi o Trichophyton rubrum (43%), tendo sido também o principal agente na tinea cruris (73,5%), tinea ungueum (74,8%), tinea pedis (72,7%) e tinea manuun (57,7%). O T. mentagrophytes var. granulare foi o segundo agente mais frequentemente isolado, e a principal causa de tinea corporis (38%) e tinea barbae (76,9%). O Mycrosporum canis foi o agente mais frequente na tinea capitis (67,1%).Discussão: As infecções por dermatófitos são frequentemente observadas na prática clínica. Vários trabalhos têm constatado diferenças etiológicas em diferentes regiões e ao longo dos anos, provavelmente relacionadas com hábitos de vida distintos. Os nossos resultados são globalmente concordantes com os resultados relatados noutros trabalhos efectuados em Portugal.

Abstract A description is provided for Microsporum equinum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Primarily a pathogen of the horse, sometimes transmitted to man. Cats, dogs, guineapigs and rabbits have been experimentally infected. DISEASE: Ringworm (dermatophytosis, tinea). Infected hairs usually fluoresce bright green under Wood's light and show a small-spored ectothrix type of invasion. In horses the lesions cannot be distinguished clinically from those caused by other species. Usually they are dry, raised and scaling and lead to circumscribed, bare patches. They may occur on any part of the animal, but particularly on the saddle and girth regions. In man, infections of the glabrous skin (tinea corporis), particularly of the arms, and of the beard area (tinea barbae) have been reported, the lesions usually being small and erythematous. GEOGRAPHICAL DISTRIBUTION: Africa (Algeria, Congo (from cases of 'Kenya Mange' of horses), Madagascar, Morocco, Sudan), Asia (Iran, Java, U.S.S.R.); Australasia and Oceania (Fiji); Europe (Belgium, Bulgaria, Denmark, France, Germany, Great Britain, (?) Greece, Italy, Netherlands, Norway, Romania, U.S.S.R.); North America (N.J., N.Y.); South America (Uruguay).

Molecular analysis of dermatophytes (based on PCR fingerprinting) revealed high clonal differentiation between the genus and species. Microsporum canis (zoophilic dermatophyte, belonging to genus Microsporum), responsible for most cases of tinea capitis in children, tinea corporis in adults and dermatophytoses in cats, is very unique in comparison with other dermatophytes. Results of most molecular studies show that there is no clonal differentiation within M. canis as distinct from other species. The aim of this study was application of (GACA)4 repetitive primer and (ACA)5 primer for typing of M. canis strains isolated from human and animals in Central Poland. Fungal strains: 32 clinical isolates of M. canis, originated from patients from Central Poland; 11 strains isolated from infected cats (6) and dogs (7), reference strains of M. canis (CBS 113480), T rubrum (CBS 120358), T mentagrophytes (CBS 120357) and E. floccosum (CBS 970.95). The genomic DNAs of the strains were used as a template in RAPD reaction. No differentiation was observed for the analyzed M. canis strains using (GACA)4 and (ACA)5 typing.
