“…This is in contrast to observation in Colombia, where T. rubrum was the dominant species 21 . The most frequently isolated dermatophyte in tinea ungium in Peru and Lebanon were T. mentagrophytes and T. rubrum 26,27 and in India, Italy, Poland T. rubrum 3,19,28 . The predominant Candida species identified in Singapore, 25 Colombia, 21 Malaysia, 20 and Italy 19 was Candida albicans , the same as our study.…”

A mycological study was undertaken in 488 patients suspected of onychomycosis in Isfahan, a large province of Iran, to gain more insight into the prevalence and aetiology of this infection. Direct microscopy of the nail clips was positive in 194 (39.8%) and fingernail onychomycosis was recognised in 141 (72.7%) and toenail onychomycosis in 53 (27.3%) cases. As agents of onychomycosis, yeast were detected in 112 (57.7%), dermatophytes in 27 (13.9%) and non-dermatophyte fungi in 55 (28.4%) patients. Of the samples cultured, Candida albicans was the most prevalent (84%) yeast. Among dermatophytes, Trichophyton mentagrophytes var. interdigitale was found to be the commonest aetiological agent (8.6%) followed by Epidermophyton floccosum and T. rubrum. Among the non-dermatophyte moulds, Aspergillus flavus was the most prevalent species (13%). Moreover, nine samples with positive direct microscopy yielded no growth. Females were affected more frequently with fingernail candidal infections than males, and children under 7 years of age were predominantly involved with candidal paronychia. The majority of fungal nail infections were characterised clinically by distal and proximal subungual onychomycosis. The growing trend towards the frequency of fingernail onychomycosis in housewives was noticeable in the last decade in Iran.

Dermatophytosis is still being considered as one of the major public health problems in many parts of the world. To identify the prevalence and etiological agents of dermatophytoses, a study was carried out between 2004 and 2006. Out of 1023 subjects suspected to have cutaneous mycoses, 348 (34%) patients were affected with dermatophytoses. The causative agents were identified macroscopically and microscopically after the clinical samples were subjected to potassium hydroxide examination and culture isolation. Epidermophyton floccosum was the most frequently isolated species representing 32.8% of isolates, followed by T. rubrum (18.1%), T. verrucosum (17.2%), T. mentagrophytes var. interdigitale (15.8%), T. mentagrophytes var. mentagrophytes (6.6%) and T. violaceum, T. schoenleinii and Microsporum canis (0.9%). The most common type of infection was tinea cruris (31.9%) affecting in particular male patients. Some other most prevalent tinea types were tinea corporis (20.7%), tinea pedis (19%), and tinea unguium (11.2%). To the best of our knowledge, this is the first report on dermatophytoses in Qazvin and the first study that shows tinea cruris as a major type of superficial fungal infection in Iran. The frequency of tinea was higher in males and tinea cruris showed a remarkably increasing tendency and was an important public health issue in Qazvin.

a b s t r a c tBackground/Objective: Trichophyton verrucosum is a serious zoophilic dermatophyte causing dermatophytic infections and skin lesions in humans and animals. Raising small ruminants beside cattle is a common practice in rural areas of Egypt. Therefore, the current study emphasizes the risk of T. verrucosum spreading through backyard farming, recognizing the interconnectedness of ruminants and humans. Methods: A total of 478 cattle, 215 sheep, 186 goats, and 250 human contacts were investigated for the presence of skin lesions, and then the lesions were sampled. All samples were examined by fungal cultures using Sabouraud dextrose agar. Results: The highest rate of T. verrucosum isolates was recorded in cattle that grew up along with sheep and goats (14.5%), whereas the lowest rate was observed in cattle reared as a single species (6.6%), with a significant difference of p ¼ 0.04, odds ratio ¼ 2.42 at a 95% confidence interval: 1.03e5.65. In addition, there was a borderline significant difference of p ¼ 0.05 between the presence of T. verrucosum pathogens in humans in contact with combined species of cattle, sheep, and goats (13.8%) and those in humans in contact with cattle only (3.3%); the odds ratio was 4.66 at a 95% confidence interval: 1.00e22.53. Moreover, the highest rate of T. verrucosum isolates in cattle was recorded in young cattle (calves). Tinea barbae was found in 11 human cases, while tinea corporis was determined in seven cases. Conclusion: Rearing different species of small ruminants with cattle supports the spread of T. verrucosum pathogens. Tinea barbae caused by T. verrucosum was predominant in the examined humans.
