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).

Abstract A description is provided for Arthroderma simii. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: The natural habitat of this species is uncertain. It was first isolated from the rhesus monkey but occurs more frequently on the fowl and it has been suggested that the fowl is the primary host, the monkey becoming infected when it raids the chicken yard for food. Also recorded from man (particularly poultry attendants), chimpanzee, dog and domestic rabbit. It has also been isolated from small mammals (gerbil, guineapig, mouse, shrew, squirrel, rat) without apparent lesions (RMVM 6, 1188; 8, 440; 11, 1889) and sporadically from soil (especially chicken yard soil). The fowl, guineapig, man, cynomolgus monkey, mouse and rabbit have been experimentally infected. DISEASE: Ringworm (dermatophytosis, tinea). In the fowl lesions are usually detected on the comb and wattles, occasionally at the base of the flank feathers. In man the body (tinea corporis) and less frequently the groin (tinea cruris), feet (tinea pedis), scalp (tinea capitis) and beard (tinea barbae) may be infected. Lesions in animals and man are scaling and very inflammatory and kerion formation is usual in scalp and beard infections of man (RMVM 7, 1241). Hair invasion is minimal except in experimental infections of guineapigs; in these the infected hairs show an ecto-endothrix type of invasion and usually a vivid green fluorescence under Wood's light. GEOGRAPHICAL DISTRIBUTION: India [see NOTES].

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.

The peritrich Epistylis unioi Gong, 1986 was collected from fry of Pelteobagrus fulvidraco during parasite surveys at Hon-ghu Lake Fish Hatchery, Hubei Province, central China in May 2010 and redescribed. Some revisions were done basedon live, silver-impregnated, and SEM specimens. The zooid is elongated and somewhat vase-like in shape, measuring56–88 × 22–38 µm in vivo. A single contractile vacuole is apically located slightly below the peristome disc. The macro-nucleus is horseshoe-shaped, always transversely situated at the foreside of the body. Haplokinety (H) and polykinety (Po)complete one and one-half circuits on the peristome before entering the infundibulum, with a distal kinetal fragment pres-ent at the distal end. Silverline system consists of 37–45 pellicular striations between peristome and aboral trochal band(TB), and of 26–33 between TB and scopula. Colony is asymmetrically and dichotomously branched, usually with onlytwo levels of branches. In addition, the telotrochs of E. unioi were also observed and its structures were described herein.Besides, obvious skin lesions caused by the ringlike base of E. unioi were detected and the relationship between these epizooites and their hosts was briefly discussed as well.

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.

Skin is an important and most visible organ of our body. Any disease related to skin can create physical as well as psychological problems in an individual. In recent years there has been increase in the incidence of skin problems in the tropical and developing countries like India due to various factors like pollution, un-hygienic condition etc. In Ayurveda all the skin disease considered in Kustha, which are further catego-rized into Mahakustha and Kshudrakustha. Dadru is one of the most common but miserable variety of Kustha affects the population of all age groups and it stands as a challenge to different medical systems inspite of many advances. Dadru is a Kapha Pitta Pradhan Vyadhi and the management of which includes Shodhana(elimination), Shamana (alleviation) and Bahirparimarjana (external application) Chikitsa. Da-dru can be correlated with Ringworm in modern terminology. Ringworm is a common fungal skin infection otherwise known as tinea. Ringworm most commonly affects the skin on the body (tinea corporis), the scalp (tinea capitis), the feet (tinea pedis), or the groin (tinea cruris). It is the commonest single fungus group infections found in an unhygienic environment. In modern various antifungal agents like Flucona-zole, Miconazole, Itraconazole etc. have been used for the treatment of these infections. In Ayurveda, so many herbs like Cakramarda, Bakuchi, Karanja, Rasona, Haridra etc. having antifungal activity which are experimentally proved to control and treat Dadru Kustha without any adverse effect.

Dermatophytoses are common fungal infections caused by dermatophytes but there are few data about this condition in the childhood. 137 children below the age of 12 and clinically diagnosed as tineas were investigated prospectively at Instituto de Puericultura e Pediatria, Rio de Janeiro, from 1994 to 1999. Hair, skin/nails scraping and pus swabs were collected from lesions and processed for fungus. Male children from 2 to 12 years were mostly affected; tinea capitis (78 cases) mainly caused by Microsporum canis (46 cases) was the most common clinical form. Tinea corporis (43 cases) mainly caused by Trichophyton rubrum (17 cases) accounted for the second most frequent clinical form. Tinea cruris (10 cases) with Trichophyton rubrum (5 cases) as the most common etiologic agent accounted for the third most frequent clinical form. Tinea pedis and tinea unguium were much less frequent (3 cases each). Trichophyton rubrum was the most common etiologic agent isolated in these cases (3 cases).
