“…Hairs were plucked by pulling them with thumb forceps (Quinn et al, 1994). On the other hand, hair and scale specimens were collected from apparently healthy animals using Mackenzie's hairbrush technique (Mackenzie, 1963). All collected animal samples were accompanied by data involving location, sex, and anatomical sites of collection of samples from the animals, in addition to date of sample collection.…”

The study investigated the prevalence and distribution of dermatophytes among domestic horses in Kwara state, Nigeria. A total of 91 samples were collected which comprised of skin scrapings and hair from both infected and asymptomatic animals. The highest dermatophyte isolation rate per total samples collected from each of the 7 different Local Government Area (LGAs) was 25% for Ilorin-East. Statistically significant differences (p < 0.05) were observed in the number of dermatophyte isolates obtained from the seven different LGAs. Dermatophytic lesions were observed on four anatomical sites of the body of horses that were sampled. These sites were the limbs, tail, head and abdominal region with dermatophyte isolation rate per total samples collected being 18.7%, 16%, 15% and 10%, respectively. Out of 85 male horses sampled, 12 were positive, and out of the six female horses sampled, two were positive. However, there was no statistically significant difference (p ˃ 0.05) between the total dermatophytes isolated from male (14.1%) or female (33.3%) horses from the seven LGAs in Kwara state. Dermatophytes isolated include Trichophyton tonsurans, Trichophyton verrucosum, Trichophyton soudanense, M. gypseum, Microsporum persicolor, Microsporum equinum and Microsporum fulvum with Trichophyton tonsurans and Trichophyton soudanense being anthropophilic.

“…O método da escova de unha para obtenção de material para diagnóstico micológico foi utilizado anteriormente em crianças (MACKENZIE 1963) KIELSTEIN (1971) não conseguiu detectar esporos nos pêlos 4 semanas após a queda das crostas e crescimento de pêlos novos de animais anteriormente enfermos. O isolamento de T. verrucosum do pêlo dos bovinos somente é possível de animais doentes ou que estejam em período de incubação.…”

“…O presente trabalho visou diagnosticar precocemente a tricofitose bovina em animais sadios provenientes de rebanhos bovinos, verificando-se a possibilidade do uso da escova de unha (MACKENZIE 1963, BRUMM 1985, como método de colheita de material capaz de identificar animais infectados de maneira inaparente, bem como determinar clinicamente o tempo de latência sob condições naturais de infecção.…”

RESUMO -Com o objetivo de se determinar o período de latência da tricofitose bovina sob condições naturais de infecção, bem como testar a utilidade da escova de unha de uso humano, foram examinados 80 bovinos sadios, com menos de 3 meses de idade, que estavam em contato com animais doentes. O dermatófito Trichophyton verrucosum (Bodin 1902) foi isolado em cultivos micológicos de 32 animais (40 %), dentre os quais 25 foram acompanhados clinicamente durante 16 semanas; destes 22 adoeceram com sintomatologia característica entre duas e oito semanas após o primeiro exame. Três animais não adoeceram apesar de serem positivos. Os resultados denotam a importância da patogenia da infecção e dos animais infectados de maneira latente para os surtos de tricofitose bovina. Concluiu-se que 88 % dos bezerros adoeceram em até 8 semanas após a instalação da infecção. O uso da escova de unha constituiu-se em método válido de colheita de material para a detecção precoce da tricofitose bovina.Palavras chave: tricofitose, bovino, diagnóstico, latência.ABSTRACT -In order to establish the period of latency of bovine ringworm in natural infection and the applicability of a human nailbrush for its detection, 80 apparently healthy calves under 3 months of age and in contact with infected animals were examined. Trichophyton verrucosum (Bodin 1902) was isolated in mycological cultures from 32 animals (40%), of which 25 continued to be clinically examined during the following 16 weeks. It was observed that 22 of these animals developed ringworm lesions from 2 to 8 weeks after the first examination. Despite being positives in mycological culture, three animals did not develop any clinical sign of infection. The results have shown the importance of the infection pathogeny and latent infection for the epidemiology of bovine ringworm. In conclusion, 88 % of the calves developed clinical signs until up to 8 weeks after infection, and the hairbrush method was found useful for the early detection of bovine ringworm.

“…Spread of Tinea capitis by fomites (Contaminated barbershop instruments, hairbrush and shared hats) is common. (2) Those species of dermatophyte fungi most likely to cause tinea capitis vary from country to country and from region to region. Additionally, the species prevalent in a given location can change with time.…”

BACKGROUND AND OBJECTIVETinea capitis is a superficial fungal infection of the hair follicle of scalp. The causative dermatophytes vary with social status and geographical distribution. The incidence is high in developing countries due to factors like poverty compounded by overcrowding, improper hygiene and illiteracy. Tinea capitis is the most common dermatophytes infection of childhood, especially in school going children. It is self-limiting disease of childhood and seldom extends beyond puberty. India being a tropical developing country with high temperature and humidity favours superficial cutaneous mycotic infections. The objective of this study was to isolate and identify the dermatophytes causing tinea capitis.
