“…These results contribute to reinforce the widely accepted opinion that ringworm is less frequent in small ruminants [3,4] perhaps due to a stronger inherited immune response against the fungus compared with that of cattle, or to other factors linked to the breeding systems. It is, however, important to note that some publications have documented, in the sheep in other countries (such as the United Kingdom, the United States, and Morocco), an increasing prevalence of the disease and the existence of extensive outbreaks [19,[38][39][40]. Moreover, it cannot be excluded that dermatophytosis in sheep and goats is an underdiagnosed disease and/or that many infection episodes are simply not reported in the official literature.…”

Introduction: Trichophyton verrucosum belongs to the dermatophyte fungi, closely related organisms that cause skin infections in animals and humans. T. verrucosum infection has been reported in livestock and people in different countries from all continents. Human cases have been reported in different areas of Pakistan, but there is little information about the animal source of the fungus. Methodology: Dermatological specimens collected in the Chitral district of Pakistan for a study on mange in livestock were retrospectively analyzed for the presence of T. verrucosum. In total, 5,873 animals (1,087 cows, 2,033 goats, and 2,753 sheep) were screened for evidence of dermatological lesions during two surveys performed in the summer and winter seasons. Skin scrapings collected from animals with lesions were analyzed by direct microscopic examination after digestion in sodium hydroxide and a real-time polymerase chain reaction (PCR) targeting pathogenic Trichophyton species. Results: At microscopy, samples from 18 cows (1.6%), 3 sheep (0.1%), and 4 goats (0.2%) were positive for fungal elements consistent with T. verrucosum. PCR confirmed the microscopy results. The prevalence was lower than that reported in other countries in intensive breeding farms. Results agree with the literature regarding factors affecting T. verrucosum diffusion, i.e., infection was more prevalent in cattle, especially in younger animals during the winter season. Conclusions: This study reports, for the first time, the presence of T. verrucosum in livestock in Pakistan. A better knowledge of the animal role in the spread of this fungus may allow the adoption of more efficient control measures and prophylaxis.

“…In Ireland, an excellent response was obtained with griseofulvin at a dose of 7.5 mg ⁄ kg for 7 days, in two infected flocks of sheep, after an outbreak of ringworm (Power & Malone, 1987).…”

“…Outbreaks of sheep ringworm have also been reported from France [4] Germany [5] and South Africa [6]. Outbreaks of ringworm infection in sheep in Ireland and Russia were studied by [7,8] respectively, and observed that weight gain of the animal was less due to Trichophyton. verrucosum.…”

Dermatophytosis is a superficial fungal infection of hair and keratinized layers of the epidermis and is caused by keratinophilic and keratinolytic genera such as Microsporum, Trichophyton and Epidermophyton. The animal age and trauma are important predisposing factors of disease. Show lambs are more susceptible to ringworm. T. verrucosum has been cited as a major agent encountered in cases of ovine and caprine ringworm. Lesions in lambs are most often noticed on the head while in goats lesions can occur beside head in pinnae, neck, and legs. The disease can be diagnosed by direct examination, fungal culture, skin biopsy and molecular diagnostic methods. This review will forecast more light on the different aspects of this disease.
