Tinea capitis gladiatorum and tinea corporis gladiatorum caused by the anthropophilic dermatophyte Trichophyton tonsurans are well-known clinical entities in individuals involved in combat sports, e.g., wrestlers and judo practitioners. We present an outbreak of Trichophyton tonsurans tinea capitis gladiatorum among wrestlers at a boarding school in Adana, Turkey. Fourteen of the 29 wrestlers examined (48.3%) harbored the pathogen, including eight asymptomatic scalp carriers, five with tinea capitis superficialis, and one asymptomatic trunk carrier. Dermatophytes were isolated from samples of the neck (1), nape (1), trunk (3) and inguinal area (2) in four of the five tinea capitis cases. A total of five inanimate objects, i.e., two wrestling mats, two pillowcases, and one sheet were also found to be positive for T. tonsurans. Mixed-marker strain typing examining 24 sequence variations in 12 gene loci confirmed that the outbreak was caused by a single strain of T. tonsurans.

Chromogenic Candida agar (OCCA) is a novel medium facilitating isolation and identification of Candida albicans, C. tropicalis, and C. krusei, as well as indicating polyfungal population in clinical samples. We compare the performance of OCCA, to CHROMagar Candida (CAC) and Sabouraud chloramphenicol agar (SCA). Vaginal swab samples from 392 women were simultaneously inoculated onto three study media. A total of 161 (41.1%) were found to be positive for fungi of which 140 (87%) were monofungal, and 21 (13%) polyfungal. One-hundred and fifty-seven samples (97.5%) were positive on CAC, 156 (96.9%) on OCCA, 148 (91.9%) on SCA and 144 (89.4%) samples were positive on all three media. The yeasts were identified by conventional methods including germ tube test, microscopic morphology on cornmeal-Tween 80 agar, and the commercial API 20C AUX. The 182 isolates were C. albicans (n = 104), C. glabrata (n = 51), C. krusei (n = 7), C. tropicalis (n = 5), C. famata (n = 3), C. kefyr (n = 3), C. zeylanoides (n = 3), C. colliculosa (n = 2), and other species of Candida (n = 4). Among the 21 polyfungal populations, 20 (95.2%) were detected in OCCA, 14 (66.7%) in CAC, and 13 (61.9%) in CAC and OCCA (P <0.05). Most polyfungal populations (47.6%) yielded C. albicans + C. glabrata. The efficiency of both chromogenic media for C. albicans was >or=92.9% at 72 h. OCCA is more efficient and reliable for rapidly identifying C. albicans and polyfungal populations than CAC. However, CAC is more efficient for identifying C. krusei and C. tropicalis. A chromogenic agar with a higher isolation rate of yeasts and better detection of polyfungal populations than SCA, is suggested as a medium of first choice when available.

Pityriasis versicolor is a common superficial mycoses of the skin. It is now recognized that the causative organisms of this infection are different species of Malassezia. The aim of this study was to determine the distribution of Malassezia species in patients with pityriasis versicolor in Adana, Turkey. In total, 97 patients positive for Malassezia elements, namely, yeast cells and short hyphae in microscopic examination, were included in the study. All samples were inoculated in plates containing modified Dixon's medium. However, only 44 of the patients (45.4%) showed Malassezia spp. in culture. Malassezia globosa (47.7%) was the most commonly isolated species followed by Malassezia furfur (36.4%) and Malassezia slooffiae (15.9%). Mixed Malassezia species were not isolated. In conclusion, M. globosa was found to be the predominant PV isolate in Adana, Turkey.

This study aimed to determine the prevalence of yeast fungi in samples from the glans penis and prepuce of circumcised and uncircumcised children. Impression preparations were made on modified Dixon and Leeming-Notman agar without cycloheximide. The isolates were identified by morphological and physiological characteristics. The yeasts were detected in 32 (28.6%) of 112 children, 12 (18.2%) being among 66 circumcised and 20 (43.5%) among 46 uncircumcised children. The most common species was Malassezia globosa (40.6%) followed by, Malassezia furfur (31.3%), Malassezia slooffiae (15.6%), Candida albicans (6.3%), Candida tropicalis (3.1%) and Candida parapsilosis (3.1%). The colonization with yeasts, and especially lipophilic species was more frequently observed among uncircumcised versus circumcised children. While age was not found to be a factor (P > 0.05), circumcision was responsible for increasing the colonization rate by 4.8 times (95% CI: 1.6-14.5) (P < 0.01). The circumcision status was not found to effect the distribution of Malassezia spp.

The aim of this study was to determine the prevalence of asymptomatic dermatophyte scalp carriage and symptomatic tinea capitis in Adana Province, Cukurova region, Turkey. For this purpose, a screening study was performed in five schools, between January 2004 and May 2005, covering a total of 5143 children with 2740 (53.3%) boys and 2403 (46.7%) girls, aged 7-14 years (9.6 +/- 2.0). The diagnosis was made using the cotton swab method with inoculation onto Sabouraud glucose agar amended with cycloheximide, chloramphenicol and gentamicin. Among 10 (0.2%) cases, six asymptomatic carriers (mean age 10.7 +/- 2.3) and four symptomatic cases (mean age 8.3 +/- 0.5) were detected, all of whom were boys and had immigrated from the south-eastern and eastern region of Anatolia, Turkey. The mean age differences were found to be statistically significant (Mann-Whitney U=3.000, P=0.046). Boys were found to be more prone to asymptomatic carriage (P=0.033), but not tinea capitis (P>0.05). Zoophilic dermatophytes, namely Microsporum canis (40%) and Trichophyton mentagrophytes var. mentagrophytes (40%) were the most commonly isolated species, followed by anthropophilic Trichophyton tonsurans (10%), while no causative agent was detected in a case (10%) with tinea capitis superficialis. Scalp cultures were found to be dermatophyte-negative after 3- to 8-month follow-up in cases with asymptomatic carriage. As a conclusion, the prevalence of asymptomatic carrier state was similar with the prevalence of symptomatic cases, and we found a predominance of zoophilic species.
