“…Frequent hosing of floors of public baths, swimming pools, etc., and discouraging antifungal foot dips (which may harbor dermatophytes) near swimming pools may be helpful as preventive measures. However, some dermatologists, citing experience, observation, and experimentation, have concluded that exogenous measures to avoid contact with pathogenic fungi or to disinfect the environment are useless (24,237). According to these investigators, individuals carry pathogenic fungi in quiescent foci on their nails, feet, and groin and the infection exacerbates when trigger factors lower resistance.…”

The etiologic agents of the dermatophytoses (ringworm) are classified in three anamorphic (asexual or imperfect) genera, Epidermophyton, Microsporum, and Trichophyton. Species capable of reproducing sexually belong in the teleomorphic genus, Arthroderma, of the Ascomycota. On the basis of primary habitat association, they may be grouped as geophilic (soil associated), zoophilic, and anthropophilic. Adaptation to growth on humans by most geophilic species resulted in diminished loss of sporulation, sexuality, and other soil-associated characteristics. The dermatophytes have the ability to invade keratinized tissue (skin, hair, and nails) but are usually restricted to the nonliving cornified layer of the epidermis because of their inability to penetrate viable tissue of an immunocompetent host. However, invasion does elicit a host response ranging from mild to severe. Acid proteinases, elastase, keratinases, and other proteinases reportedly act as virulence factors. The development of cell-mediated immunity correlated with delayed hypersensitivity and an inflammatory response is associated with clinical cure, whereas the lack of or a defective cell-mediated immunity predisposes the host to chronic or recurrent dermatophyte infection. Chronic dermatophytosis is mostly caused by Trichophyton rubrum, and there is some evidence that mannan produced by this fungus suppresses or diminishes the inflammatory response. Since dermatophytes cause a communicable disease, modes of transmission and control are discussed as well as a survey of recent trends in therapy. Collection of specimens, culture media, and tests for identification are also presented. Genetic studies have led to an understanding of incompatibility mechanisms, pleomorphism and variation, resistance to griseofulvin, and virulence. Molecular biology has contributed to our knowledge of the taxonomy and phylogenetic relationships of dermatophytes.

“…Dermatophytosis is a common disease in tropical countries like India, due to factors such as heat and humidity which provides a fertile ground for the abundant growth of dermatophytes. 7 In the present study maximum cases of dermatophytosis were reported from June to August revealing the fact that hot and humid weather during the monsoons has a great impact on the occurrence of dermatophytosis (Table 6).…”

“…Singh et al reported Tinea corporis in 58.84% of cases, Patel et al from South Gujarat in 64% of cases, Venkatesan et al from Chennai in 64.8% of cases, Sen et al from Assam in 48% of cases. [6][7][8]1 However, few other Indian studies have reported Tinea cruris as the commonest clinical variety. Complete numeration due to tight clothing, maceration and high rate of sweating in groin and waist regions makes these sites more vulnerable to dermatophytosis.…”

Background: Superficial fungal infections are the most common skin diseases, affecting millions of people throughout the world. Aim of the study was carried out to find, the effect of seasonal variation and socio-economic status on the prevalence of dermatophytes.Methods: A total of fifty clinically suspected cases of dermatophytosis were subjected to mycological studies.Results: Out of which 32 (64%) were culture positive Tinea corporis was the most common clinical type followed by Tinea cruris. Tricophoton rubrum 17/32 (53.12%) was the most common isolate followed by T. mentagrophytes 9/32(28.12%), T. tonsurans 3/32(9.37%), T. verrrucosum 2/32(6.25%) and T. schoenleinii 1/32(3.12%). Most of the patients belonged to the middle socio-economic group (28/50) followed by lower socio-economic group (19/50) maximum cases of dermatophytosis were reported from June to August revealing the fact that hot and humid weather during the monsoons has a great impact on the occurrence of dermatophytosis.Conclusions: It may therefore be concluded that dermatophytosis is now a days a serious public health problem in view of its high occurrence in the world wide population.
