“…M. audouinii is commonly regarded as an anthropophilic dermatophyte since isolation from animals and soil is rare [ 19 , 20 ]. Transmission is thought to be human-to-human through habitual contact [ 21 ].…”

We report here two cases of tinea capitis caused by Microsporum (M.) audouinii in Côte d’Ivoire, West Africa. The patients were a three-year-old boy and a six-year-old girl who presented with scaly patches on the scalp. The causative fungus was isolated using an adhesive tape-sampling method and cultured on Sabouraud dextrose agar plates. It was identified as M. audouinii both by its macroscopic and microscopic features, confirmed by DNA sequencing. These are the first documented cases of M. audouinii infections confirmed with DNA sequencing to be reported from Côte d’Ivoire. The practicality of the tape-sampling method makes it possible to carry out epidemiological surveys evaluating the distribution of these dermatophytic infections in remote, resource-limited settings.

“…Epidermophyton (Chah et al, 2012;Habeb et al, 2016). The dermatophytes are both keratinophilic and keratinolytic, which means they are able to digest keratin in vitro in their saprophytic state as well as in vivo in their parasitic state to produce ringworm (Weitzman and Summerbell, 1995) The disease is transmitted either directly by contact with an infected host or indirectly by contact with formites contaminated with arthrospores (asexual spores formed in the hyphae of the parasitic stage) or conidia (asexual spores formed in the free living environmental stage) Ringworm in cattle is characterized by circumscribed, scaly, alopecic, thickly crusted, grayish-white lesions raised above the skin, mostly occurring on the head and neck (Haggag et al, 2017).…”

Dermatophytosis is a contagious, zoonotic skin disease affecting a variety of domestic and wild animals including man. It is caused by a group of morphologically and physiologically related fungi in the Genera Trichophyton, Microsporum and Epidermophyton.Trichophyton mentagrophytes was responsible for dermatophytosis on an 8-month-old Friesian-Bunaji cross bred calf in Jos, Nigeria. The diagnosis was based on clinical signs, direct microscopy and isolation of aetiologic agent on Sabouraud’s dextrose agar supplemented with chloramphenicol and cycloheximide. The lesions involving the face, muzzle and jaw were circular, alopecic, thickly crusted, and grayish-white raised above the skin. Direct microscopic examination of skin scrapings and hair pullouts in 10%KOH revealed chains of arthroconidia on the surface of infected hairs. Colonies were flat, white, and granular to fluffy with yellow reverse side. The isolate was urease test positive when inoculated on to Christensen’s urea agar. Microscopically, many spherical microconidia arranged in dense grape-like clusters with few multiseptate, thin and smooth walled macroconidia, typical of Trichophyton mentagrophytes were observed. Bovine dermatophytosis is economically important both in the livestock and leather industries as well as in public health. The need for prompt diagnosis and treatment of infected animals as preventive and control measures was emphasized

“…In Nigeria, reports on the prevalence of dermatophytosis in domestic animals and cattle, in particular, are scanty [7]. Earlier studies on dermatophytoses of domesticated animals in different parts of the country in Ibadan, Oyo State [8], in Zaria, Kaduna State [9], in Oyo State [10] and a more recent report from Nsuka, Enugu State [11], did not cover cattle. In the study conducted in Enugu, Anambra, Ebonyi, Abia, Imo, Kogi and Delta States of Nigeria [12], only 55 out of a total of 538 animals in that study were cattle.…”

Background and Aim:Dermatophytosis is an infection of the superficial, keratinized structures of the skin, nails, and hair of man and animals caused by a group of fungi called dermatophytes in the genera Trichophyton, Microsporum, and Epidermophyton. The prevalence of dermatophytosis among cattle in Nigeria and Plateau State, in particular, is yet to be fully determined. This study aimed to determine the prevalence and the distribution of dermatophytosis lesions on cattle in Plateau State, Nigeria.Materials and Methods:Four hundred and thirty-seven cattle showing visible skin lesions suggestive of dermatophytosis were drawn from nine local government areas (three each) from the three senatorial districts of Plateau State, Nigeria. Skin scrapings were aseptically collected using a cross-sectional study, in which sampling units were selected using purposive sampling method. Samples were processed for both direct microscopic examination and isolation of dermatophytes in culture. The isolates were stained with lactophenol cotton blue and identified microscopically based on the size, shape, and arrangement of macro- and micro-conidia. The dermatophytes were further identified by determining the sequences of the internal transcribed spacer regions of their ribosomal DNA. Data were analyzed and presented as percentages, bar graph, and Chi-square test of association. p≤0.05 was considered statistically significant.Results:The overall prevalence rate of bovine dermatophytosis in Plateau State was found to be 11.0%. Trichophyton verrucosum was more frequently isolated (54.2%) than Trichophyton mentagrophytes (45.8%). Age, breed, management practice, and season were significantly associated with the occurrence of the disease (p<0.05).Conclusion:Dermatophytosis among cattle may be of public health significance in Plateau State, Nigeria. This is the first report on the prevalence and distribution of dermatophytosis lesions on cattle from Plateau State, Nigeria.

Dermatophytes from skin lesions of domestic animals in Nsukka, Enugu State, Nigeria

Abstract: Anthropophilic dermatophytes are among the fungal agents associated with dermatophytosis in animals in Nsukka Agricultural Zone. These dermatophytes could constitute health risks to humans in contact with the animals.
