Dermatophytes constitute an infection source for both animals and humans, representing zoonosis. The objective of this work was carry out an updated review on dermatophytes general characteristics, the clinical aspects of each infected animal species and their zoonotic potential. For this, all the published information available in PudMed database was compiled. This review describes the worldwide distribution of disease caused by dermatophytes, the zoonotic behavior of the disease, the physiopathogenic characteristics, linked to the host's immune response and oxidative stress behavior in bovine trichophytosis. On the other hand, the dermatophytes classification, different diagnostic methods, the macro and micro characteristics of the colonies of dermatophytes and their differentiation are exposed. It also addresses the form transmission of the disease and clinical aspects of disease in some animal species, including humans. Concluding that dermatophytes constitute a zoonosis, of great importance at present, therefore, they should be object of epidemiological surveillance considering the term of a single health. On the other hand, it is important to consider the economic losses caused by the infestation in cattle specifically. [ABSTRACT FROM AUTHOR]

BACKGROUND: Ringworm is one of the most frequent superficial mycosis, representing 5 to 10% of these. OBJECTIVES: To evaluate the prevalence level of dermatophyte infection and to establish the epidemiology in the metropolitan area of Monterrey, Nuevo Leon, Mexico, correlating this infection with risk factors such as age, gender, diabetes, AIDS, hyper and hypotension. MATERIALS AND METHODS: An analytical and transversal epidemiological study carried out from November 2017 to July 2018, including patients with signs and symptoms compatible with infection due to dermatophytes in nails and feet. Patients were submitted to a clinical evaluation in a standard format including a combination of epidemiological variables. RESULTS: There were included 168 patients, from which 83.3% had a positive direct microscopic examination proofing infection, while the prevalence of dermatophytosis (positive culture) was of 22%. T. rubrum (45%) was one of the most frequent species, followed by T. mentagrophytes sensu lato (23%), Epidermophyton floccosum (9%), T. tonsurans (7%) and Trichophyton spp (17%). CONCLUSIONS: T. rubrum and T. mentagrophytes sensu lato (23%) were the most frequent etiological agents and its certain diagnosis is one of the main tools for the proper and efficient treatment, so avoiding therapeutical failures and the development of resistant fungal strains.

Tinea capitis is a frequent dermatophytosis of childhood. Clinically, it can be divided into its dry or inflammatory presentation, the former accounts for up to 90% of all cases. Diagnosis is made by microscopic examination of tonsured hair with potassium hydroxide (KOH), in which parasitation of the hair can be observed, or by isolation of the dermatophyte in Sabouraud agar. The dermoscopic examination of the hair and scalp is known as trichoscopy. It has proven to be very useful in the diagnosis and screening of some hair disorders, among them, infectious diseases such as tinea capitis. The presence of certain trichoscopic features allows identifying and differentiating between these entities. The most commonly reported trichoscopic features in tinea capitis patients have been coma hairs and corkscrew hairs, which have been described as markers of this particular disease.

Tinea nigra is a superficial mycosis caused by a yeast-like fungus Hortaea werneckii, is melanized, halophilic, and grows warm regions, especially in beach areas. We present five cases of clinical and mycological proven tinea nigra, four were male adults and one of 2 years-old girl. Three cases were localized on palm and interdigitale folds, one on sole and one more with two locations on hand and foot, all were associated with varying degrees of hyperhidrosis. All five patients responded well to therapy based on keratolytic, skin drying and topical antifungal. [ABSTRACT FROM AUTHOR]

Background: Extraungual dermatophytomas are masses of hyphae observed under direct examination that at the physical examination correspond to typical tinea. Objective: To determine the frequency of extraungual dermatophytomas and risk factors at the Instituto de Dermatología y Cirugía de Piel Prof. Dr. Fernando A Cordero C of Guatemala. Patients and method: A retrospective and cross study in 15 patients diagnosed with tinea corporis, and presence of dermatophytoma under microscopic examination, at the Instituto de Dermatología y Cirugía de Piel Prof. Dr. Fernando A Cordero C in Guatemala, from June 2008 to September 2009. Results: Presence of extraungual dermatophytomas was evaluated in 15 cases (0.5%) of the total of fungal cases and account for 1.6% of the caused by dermatophytes. Conclusions: 73.3% of patients with extraunguals dermatophytomas presented tinea corporis and previous treatment with topical steroids. [ABSTRACT FROM AUTHOR]

Reticulated and confluent papillomatosis is a chronic and recurrent disease that occurs predominantly in young adults and teenagers. Its main characteristics are verrucose papillomatous injuries as brown plaques spreading to thorax, neck and face. Patients go to consultation due to its dermatosis aesthetic effect. It is hard to establish its diagnose (often late), even to dermatologists, due to its low incidence. Clinically, the eruption is often confused with tinea versicolor or acanthosis nigricans. Potassium hydroxide fungus staining is negative in most cases, and minocycline is the gold standard therapy. We report a case of a 17 year-old patient with typical clinical and histological features of this illness; we too review literature and diagnose criteria to this rare disease. [ABSTRACT FROM AUTHOR]

We review a case of a patient who presented with a dark stain on the right palm. The microbiological examination found that the infection was caused by a pigmented fungus, Hortaea werneckii, etiological agent of tinea nigra. This is a benign infection with an effective treatment when appropriate diagnosis is made. Through a non-invasive technique it is possible to establish its diagnosis and to rule out easily other more severe diseases in the clinical examination. [ABSTRACT FROM AUTHOR]
