Abstract A description is provided for Microsporum ferrugineum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Recorded only from man. Experimental animals are not susceptible to infection. DISEASE: Ringworm (dermatophytosis, tinea). Primarily affecting the scalp (tinea capitis) and less frequently the glabrous skin, particularly of the face (tinea corporis) of children. Scalp lesions are usually non-inflammatory, scaling patches of alopecia. Infected hairs are surrounded by sheaths of small spores in a mosaic arrangement, and usually fluoresce under Wood's light, but Germeraad & Klokke (E. Afr. med. J. 39: 515-519, 1962) saw no distinct fluorescence in 22 cases in Uganda. Skin lesions are usually scaly, with little or no inflammation. GEOGRAPHICAL DISTRIBUTION: Africa (Angola, Cameroons, Cape Verde Islands, Congo, French West Africa, Mozambique, Nigeria, Ruanda-Burundi, Uganda); Asia (China, Formosa, Hawaii, India, Indo-China, Israel, Japan, U.S.S.R.); Europe (Bulgaria, Czechoslovakia, Hungary, France, Italy, Poland, Romania, U.S.S.R., Yugoslavia (Macedonia)); North America (? Texas); South America (? Brazil,? Uruguay).

Abstract A description is provided for Microsporum audouinii. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Primarily a pathogen of man. Also recorded on the dog, gibbon, guineapig and monkey. Most strains are not pathogenic for experimental animals. DISEASE: Ringworm (dermatophytosis, tinea). Infected hairs usually fluoresce bright green under Wood's light and are surrounded by an ectothrix sheath of small spores in a mosaic arrangement. In man, the scalp (tinea capitis) and less frequently the glabrous skin (tinea corporis) may be infected. Children are most susceptible, and in adults infection is usually confined to the glabrous skin, although a few scalp infections have been reported. Rothman et al. (RMVM 1, 614) noted that fatty acids from adult hair fat inhibited M. audouinii in vitro and suggested that this was the reason for lower incidence of infection in adults, but Kligman & Grinsberg (RMVM 1, 1800) found that adult sebum was not more fungistatic than that of children. Scalp lesions are usually circular, scaling areas of alopecia and, in contrast to M. cants infections, there is generally very little inflammatory reaction. Skin lesions are usually circulate scaling areas with clearing centres. Kligman (RMVM 1, 2510; 2, 2484) studied the pathogenesis of tinea capitis due to M. audouinii. GEOGRAPHICAL DISTRIBUTION: Africa (Algeria, Chad Republic, Cameroons, Congo, Egypt, French West Africa, Guinea Republic, Madagascar, Morocco, Mozambique, Nigeria, South Africa, Tunisia); Asia (India, Java, Palestine, Persia, Turkey), Australasia & Oceania (Australia (New South Wales, Western Australia), New Zealand), Europe (Austria, Belgium, Czechoslovakia, Denmark, France, Germany, Great Britain and Ireland, Hungary, Italy, Netherlands, Poland, Portugal, Romania, Spain, Sweden, Switzerland, U.S.S.R., Yugoslavia), North America (Canada, U.S.A.), Central America and West Indies (Cuba, Jamaica, Puerto Rico); South America (Argentina, Brazil, Chile, Ecuador, Venezuela).

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).

Abstract A description is provided for Nannizzia obtusa. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Primarily a pathogen of the pig, occasionally transmitted to man. Guinea-pigs have been experimentally infected. DISEASE: Ringworm (dermatophytosis, tinea). In pigs lesions are circular and circumscribed to irregular in outline, sometimes involving almost the whole body. They are reddish in colour and are frequently covered with brownish crusts. Alopecia and pruritis do not occur (RMVM 5, 226, 491-492). In man the scalp (tinea capitis) and glabrous skin (tinea corporis) may be infected. Scalp lesions reported have shown a kerion type of reaction with endothrix hair invasion; in some cases infected hairs have fluoresced light green under Wood's light. GEOGRAPHICAL DISTRIBUTION: Reported from Africa (Kenya), Australasia (Australia, New Zealand); North America (Canada, U.S.A. (Ind., Kans., Ky, Miss., N.J., Pa)), Central America and West Indies (Mexico, Cuba). Possibly world-wide in distribution.

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.

Abstract A description is provided for Nannizzia fulva. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Recorded only from man (but see NOTES). Guinea-pigs have been experimentally infected. DISEASE: Ringworm (dermatophytosis, tinea). Nannizzia fulva is present in the soil and apparently only rarely pathogenic. The scalp (tinea capitis) and glabrous skin (tinea corporis) may be infected. Skin lesions are inflammatory. The only proved case of scalp infection is that recorded by Uriburu (1909); according to Sabouraud (Les Teignes, 1910, p. 241) in this case there was a light inflammatory reaction and infected hairs were indistinguishable from those in M. audouinii infections. In experimental inoculations of guineapigs (Rdzanek, pers. comm.) N. fulva was slightly less virulent than N. gypsea and N. incurvata, the reaction varying from negative to strongly inflammatory. A few ectothrix hyphae breaking up into arthrospores were seen on some hairs, and infected hairs did not fluoresce under Wood's light. GEOGRAPHICAL DISTRIBUTION: Africa (Tanzania), Europe (Great Britain, Hungary, Yugoslavia), South America (Argentina). Probably world-wide in distribution in the soil, but there may be local limiting factors (e.g., in Great Britain it has been recorded only for Bristol, Somerset, and Wiltshire).

Abstract A description is provided for Nannizzia gypsea. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Recorded only from man (but see NOTES). Guinea-pigs have been experimentally infected. DISEASE: Ringworm (dermatophytosis, tinea). Nannizzia gypsea is apparently widespread in soil and only rarely pathogenic. The scalp (tinea capitis) and glabrous skin (tinea corporis) may be infected. Skin lesions are inflammatory, but details of only two scalp infections are known. In both the lesions were inflammatory; in one favus-like crusts were also found and in the other hair invasion was of the large-spored ectothrix type. In experimental inoculations of guineapigs (Rdzanek, pers. comm.) N. gypsea was slightly more virulent than N. incurvata and N. fulva, the reaction varying from negative to strongly inflammatory, a few ectothrix hyphae breaking up into arthrospores were seen on some hairs, and infected hairs did not fluoresce under Wood's light. GEOGRAPHICAL DISTRIBUTION: Asia (Japan), Australasia and Oceania (Australia (New South Wales), New Zealand, Raratonga, Cook Island), Europe (France, Great Britain, Italy); North America (Tenn.). Probably of world-wide distribution in the soil.

Abstract A description is provided for Microsporum distortum. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Recorded on man, monkey, dog and horse. Some human infections have been in children with a history of contact with cats with skin lesions but these animals were not examined by culture. Rats, guineapigs, rabbits and cats have been experimentally infected. DISEASE: Ringworm (dermatophytosis tinea). Similar to M. canis infections. Infected hairs fluoresce pale to bright green under Wood's light and are encrusted with ectothrix sheaths of small spores in a mosaic arrangement. In man, the scalp (tinea capitis) and glabrous skin (tinea corporis) may be infected. Most reported infections have been in children under 7 years old. Scalp lesions have been reported only in children, and usually consist of scaling patches of alopecia, with some erythema at the margin. Skin lesions are usually small, circular, with erythematous borders and dry, scaling centres. In animals scaling patches of alopecia are the usual symptom. GEOGRAPHICAL DISTRIBUTION: Australia (New South Wales), New Zealand (apparently restricted to Otago), U.S.A. (Iowa, Ga). All cases reported from U.S.A. have been in pet monkeys probably recently imported from Central America, and in humans and dogs which had been in contact with the monkeys.

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.

Background. The use of mobile applications in dermatology to support remote diagnosis is gaining acceptance, particularly in rural areas, where dermatology services are commonly managed by healthcare personnel with no specialty training. Moreover, ontologies—sets of concepts that represent knowledge in a given domain—are increasingly being used to support medical diagnosis. A specific case is ONTODerm: an ontology to aid dermatological diagnosis. However, there is little information on the combined use of mobile applications and ontologies as support solutions in dermatology. Objective. Assessing the reliability of ONTODerm as a tool to support remote dermatological diagnosis when used together with a mobile dermatological application in underprivileged areas. Methods. A mobile application that allows characterization of skin lesions was developed, and the information about the lesions was sent to ONTODerm. An exploratory study was conducted in a remote area without access to a dermatologist. A total of 64 dermatological queries were recorded in the application and consulted with ONTODerm. Later, an experienced dermatologist evaluated the characterization and diagnosis of each query to determine the accuracy of the system. Results. The results showed that the probability of obtaining a correct diagnosis was between 64.4% and 85.6% with a confidence interval of 95%. A higher accuracy rate was obtained when the skin lesion occurred on the face or when its border was categorized as poorly demarcated. Conclusions. This study demonstrates the implementation of a teledermatology strategy based on mobile applications and domain ontology-driven knowledge base to provide timely assistance to healthcare professionals. This approach was found to be pertinent in the Colombian rural context, particularly in forest regions, where dermatology specialists are not available. The results of this article do not represent a final validation of the proposed approach; they suggest how the ontology can be improved to effectively support medical staff in marginalized regions.
