“…Furthermore, living conditions, large family size and close contact with other infected children at school may facilitate fungal transmission. In this study, anthropophilic species were the main isolated dermatophytes (68.1%), in particular T. violaceum , in agreement with other studies 9,10 . In addition, zoophilic agents are in clear recrudescence and are isolated from almost one‐third of the samples.…”

Mycoses are frequent affections in childhood. Fungal type varies according to the age and the affected organ. The aim of this study was to determine the aetiological agents of childhood dermatomycoses and to draw attention to the diversity of their clinical manifestations. Retrospective study dealing with children's cases with age <16-year old and having dermatomycosis diagnosed between 1991 and 2005 at the Parasitology and Mycology Laboratory of Sfax University Hospital. A total of 4559 children suspected to have superficial mycoses were examined. Dermatomycosis diagnosis was confirmed in 49.3% of cases. Dermatophytes were the most prevalent fungal agents and accounted for 1865 cases (80.6%) dominated by Trichophyton violaceum (54.1%) and Microsporum canis (24.5%). Tinea capitis (69.4%) was the most common type of infection, followed by tinea corporis (20%). Superficial yeast infections (442 cases) were dominated by Malassezia infections (71%). Candida infections were mainly due to Candida albicans (58%). The clinical features of paediatric dermatomycoses vary with the age of the children: tinea capitis and tinea corporis were more frequent before 13 years of age. After this age, tinea versicolor and onychomycoses became more common.

“…However, tinea capitis was the common clinical presentation in children aged 0-10 years. Our results confirm those of previous studies in Iran [13,24] and other regions of the world [32,33]. However, our finding is in contrast to others who reported tinea pedis [17,18], tinea capitis [15,32], and tinea cruris [19,20] as the predominant clinical observations in north and center of Iran.…”

Dermatophytosis is a common mycotic infection of the skin, nail, and hair, associated with major public health concern worldwide. Various species of dermatophytes show significant differences in susceptibility to antifungals. Here, we present the antifungal susceptibility of a large collection of molecularly identified dermatophyte isolates obtained from tropical region of south of Iran. A total of 9485 patients clinically suspected to have cutaneous fungal infections were examined. Dermatophytosis was confirmed in 1502 cases by direct microscopy and culture. Three hundred and sixteen isolates recovered in culture were identified to species level using PCR sequencing of ITS region and RFLP. Tinea corporis was the most prevalent type of clinical manifestation (35.2 %), followed by tinea cruris (17 %), tinea capitis (12.8 %), tinea pedis (11.3 %), tinea manuum (11 %), tinea unguium (6.9 %), and tinea barbae (5.8 %). Trichophyton interdigitale was the most common isolate (49.36 %), followed by Trichophyton rubrum (18.98 %), Epidermophyton floccosum (13.29 %), Microsporum canis (9.17 %), Arthroderma benhamiae (T. anamorph of A. benhamiae; 5.38 %), and Trichophyton tonsurans (3.79 %). Overall, irrespective of the geographical region, terbinafine was the most potent antifungal against all isolates, with an MIC range of 0.002-0.25 μg/mL, followed by itraconazole (0.004-0.5 μg/mL), griseofulvin (0.125-8 μg/mL), and fluconazole (4-128 μg/mL). Analysis of our data revealed a significant increase in the frequency of A.benhamiae, which definitely warrants further investigation to explore source of this infection in south of Iran. Moreover, terbinafine was the most effective antifungal against all isolates, in vitro.

Most of the studies published thus far now show that Malassezia globosa is the predominant species found in the lesions of pityriasis versicolor, at least in temperate climates. The authors' recent findings confirm these results. The etiologic role of M. globosa in pityriasis versicolor is based, even more than on its isolation in a high percentage of cultures, on its identification by direct microscopy as typical globose yeast cells producing pseudohyphae in almost 100% of cases. The confirmation of the pathogenic role of this species in pityriasis versicolor could help in understanding these conditions, which are still unclear, which promote its transformation from the saprophytic stage present in healthy skin to the parasitic one, and could also help in selecting the best therapeutic measures.
