“…They also found a relationship between the spread of dermatophytosis and livestock infected with dermatophytes. The same results have been reported by several authors in different provinces in Iran (Dehghan et al, 2009;Khosravi et al, 1994;Sepahvand et al, 2009;Bassiri-Jahromi et al, 2009;Falahati et al, 2003;Pakshir et al, 2006). Finally, this study showed the importance of cattle ringworm in Sarab city and revealed the dominant role of T. verrucosum in cattle dermatophytosis.…”

Ringworm is a fungal and zoonotic infectious disease, caused by different species of dermatophytes. Lesions of ringworm are usually found on the head, muzzle, ears, neck, and particularly, around the eyes of the infected animals. This study was conducted to determine the prevalence of cattle ringworm in native farms of Sarab city in Iran. A total number of 1150 cattle in native dairy farms of Sarab city were examined in this study from July 2007 till June 2008. The animals were classified into two age groups of less than 2 years and more than 2 years. Each animal was thoroughly examined for skin ringworm lesions, then, microscopic and culture examinations were carried out on samples obtained from ringworm lesions of infected animals. According to the results of this study among 1150 cattle, 188 of them (16.34%) were clinically positive for skin ringworm lesions. After microscopic and culture examinations, 150 animals (13.04%) were confirmed for dermatophyte infections. Trichophyton verrucosum was isolated in 100% of positive samples. The prevalence of ringworm among cattle less than 2 years and more than 2 years were 15 and 9% respectively, which showed significant difference between them. This study is the first research on the prevalence of cattle ringworm in Sarab city which indicated the relatively high prevalence of the disease and revealed the dominant role of T. verrucosom in cattle ringworm.

“…Despite the variability of fungal species by geographic regions in 1990s, zoophilic fungi such as T. verrucosum overwhelmed the anthropophilic across some regions of the country, including certain endemic areas [14][15][16]. However, today anthropophilic T. mentagrophytes (T. interdigitale), Epidermophyton floccosum, and T. rubrum are the main pathogens in Iran [17][18][19][20][21][22][23][24][25][26][27].…”

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.

Background: Candida species are known as the most common fungal pathogens isolated from clinical specimens that can develop complications ranging from cutaneous to systemic diseases. Objectives: The present study was conducted to evaluate the diversity and distribution of Candida species in various kinds of cutaneous candidiasis in Tehran, Iran. In addition, the critical effects of several predisposing factors on the induction and progression of the disease were considered. Methods: A total of 3000 samples were taken from March 2014 to 2015. The samples were examined using direct microscopy and culturing method. The polymorphism analysis was performed by using polymerase chain reaction -restriction fragment length polymorphism (PCR-RFLP) technique. The internal spacer region (ITS) of the fungal rRNA genes was recruited for PCR amplification of target sequences and Msp1 enzyme was employed to digest PCR amplicons. Results: Out of 3000 samples, yeast was recovered in 290 (9.67%) cases. Onychomycosis was observed predominantly in 164 nail samples (56.5%). The majority of patients were within the age range of 51 -60 years (22.14%). Women working at home (housewives) showed the highest percentage of people at risk (n = 135, 46.5%). Among patients with underlying diseases, diabetic patients with 46 cases (14.2 %) had the highest susceptibility to candidiasis. Genotypic identification showed that Candida albicans is the most common species (n = 132, 45.5 %) recovered from clinical samples, followed by C. parapsilosis (n = 77, 26.5%), C. glabrata (n = 22, 7.5 %), C. krusei (n = 16, 5.5 %), C. tropicalis (n = 37, 12.7 %), and C. guilliermondii (n = 6, 2%). Conclusions:The results of the present study, compared to the previous studies, showed a significantly lower prevalence of cutaneous candidiasis. Among Candida species, C. albicans was still the most common infectious agent isolated from clinical samples. Shifting toward non-albicans Candida species was not confirmed in this study. In addition, our study revealed that there is a direct correlation between some predisposing factors including age of patients, and existence of some non-infectious diseases (e.g. metabolic disorder) and occurrence of Candida infection.
