“…Out of the 348 positive cases, 24 (6.9%) were incompletely identified because of a negative culture growth and positive direct examination. The probable reason for negative culture growth from microscopically positive samples could be that highly contaminated samples were grown over by fast‐growing saprophytic species, which prohibited the growth of dermatophytes even on a medium with cycloheximide 11 . Furthermore, this finding of 62 (17.8%) positive cases with negative results from direct examination is in accordance with certain other researches showing a similar percentage of negative results in direct microscopy 12–14…”

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.

“…Non‐inflammatory ‘gray patch’ variety was the most common clinical type of TC seen in 163 (50.2%) children, followed by black‐dot variant in 100 (30.2%) patients. In an earlier report from Kuwait in 1993 (4), this variety was found in 87.3% of patients, followed by kerion in 8 (5.1%), seborrheic‐like pattern in 6 (3.8%), and black‐dot variety in 4 (2.5%) patients (Table 3). The overall percentage of the non‐inflammatory ‘gray‐patch' and the black‐dot varieties of TC (80.9%) has declined over these years, as compared to 97.6% (3) and 87.3% (4) reported earlier (Table 3).…”

“…Moreover, the endemic species in any country may change with time. The last reported studies on the epidemiology of TC from Kuwait were conducted in the late eighties and early nineties (2–4). Therefore, this study was planned to determine the currently prevalent clinical patterns of TC, and their etiological dermatophytic species in the Farwaniya region, which is located in the central part of the State of Kuwait.…”

Analysis of 325 patients (182 males, 143 females) of mycologically proven tinea capitis (TC) seen over a period of two years from January 2001--December 2002 in the Farwaniya region of Kuwait is presented in this study. The age range was 8 months to 17 years. Peak incidence was observed in the 3-14 year age group (79.6%). Positive family history and contact with pets were noted in 22% and 36.7% of the cases, respectively. The non-inflammatory 'gray patch' variety was the most common clinical type, seen in 163 (50.2%) children, followed by the black-dot variant in 100 (30.2%) patients. A significant proportion of the cases (16.6%) had the uncommonly reported seborrheic dermatitis or dandruff like pattern. Highly inflammatory kerion was encountered infrequently (2.5%). Seven species of dermatophytes were isolated; Trichophyton violaceum in 135 (41.5%), followed by Microsporum canis in 89 (27.4%), Microsporum audouinii in 48 (14.8%), Trichophyton mentagrophytes var. mentagrophytes in 31 (9.5%), Trichophyton verrucosum in 15 (4.6%), Trichophyton tonsurans in 6 (1.9%) and Microsporum gypseum in 1 (0.3%) patient. T. violaceum was the most common fungus responsible for the black-dot variety (89/100) and kerion (4/8) patients. Three cases of kerion (33.3%) grew T. verrucosum. M. canis was the most common species isolated from the 'gray patch' cases (79/163; 48.5%) followed by almost equal prevalences of T. violaceum (16.6%), M. audouinii (15.3%), and T. mentagrophytes var. mentagrophytes (12.3%). Among the seborrheic type of cases, M. audouinii was the most common fungus isolated in 20/54 (37%) followed by T. violaceum in 15 (27.8%), T. mentagrophytes var. mentagrophytes in 9 (16.7%), M. canis in 8 (14.8%) and T. verrucosum and T. tonsurans in one (0.3%) patient each. The results are significantly different from those in earlier studies in Kuwait.

“…[18] It is also not known whether there are substances produced by NDM in culture that would inhibit the growth of dermatophytes in coinfected samples (6.7%, i.e., in 4/60 positive cases, coinfection of NDM with dermatophytes was seen), or whether fast growing, NDM molds have overgrown dermatophytes that require more stringent conditions for their isolation compared with NDM. [19] Also, use of traditional remedies whose mechanism of action are unknown, by some of the respondents to treat their lesions, may perhaps have altered the in vitro isolation of dermatophytes. Earlier, they were considered as contaminants, but now they are important etiological agents of dermatophytosis.…”

Background:Because of the widespread prevalence of the various cutaneous mycoses in a tropical country like India, it is important to know their patterns of etiology and clinical presentations.Aim:The present study was conducted in order to identify the clinical pattern of various cutaneous mycoses and the common etiological agents affecting the study populations admitted in SMS Hospital, Jaipur, in North India.Materials and Methods:Skin scrapings and hair and nail samples of 160 patients with clinical suspicion of dermatophytosis were collected and subjected to direct microscopy and were cultured in Sabouraud's dextrose agar. Fungal species were identified by macroscopic and microscopic examination. Data were presented as simple descriptive statistics (SPSS, Version 17.0 (Chicago Il, USA). Epi Info Version 3.5.1 (CDC, Atlanta, Georgia, USA).Results:Among the 160 clinically suspected patients of cutaneous mycoses, 60 (37.5%) were confirmed by culture. Dermatophytes and non-dermatophytes (NDM) were isolated from 66.6% (40/60) and 33.3% (20/60) of the positive cultures, respectively. Tinea capitis (50%) 30/60 was the most frequent clinical pattern and genus Trichophyton violaceum 32.5% (13/40) was the most common isolate in dermatophytosis-positive samples. Among the patients positive for NDM by culture, Tinea unguium 35% (7/20) was the most common clinical presentation and Aspergillus species 40% (8/20) were the most common etiological agents isolated.Conclusion:Although dermatophtes have been isolated from the cases of cutaneous mycoses all over the world with various frequencies, the role of NDM in the different cutaneous infections other than those of nail infections need to be evaluated.
