Introduction Otitis is a frequent problem in dogs – in many cases we deal with a recurrent problem. Looking at the etiology we have to take into account bacterial infections, yeasts (Malassezia spp.), parasites (Otodectes cynotis as well as Demodex species) and foreign bodies. Less often we deal with neoplasia, allergies (especially food intolerance), autoimmune diseases or endocrinopathies tha...

The objective of this study was to use nanohybrid Curcumin Cur-ZnO and Cur-MgO as well free curcumin detect, isolate, characterize, inhibit the development certain yeasts locally isolated from some spoilage foods. Yeasts responsible for spoiling were recovered in 21 different colonies cheese, cooked pickles, fig jam, apple dates, rice, canned chickpeas, dried figs. Nine yeast isolates chosen fu...

BACKGROUND AND PURPOSE Seborrheic dermatitis is a chronic and recurrent superficial dermatitis in which Malassezia species play an important role. There are different Malassezia species, which have been recently reported to be resistant to common antifungals. Natural sources can be useful alternatives to reduce the emergence of this resistance. Kombucha tea is believed to have potential antimic...

Melanin-like pigment produced in vitro and in vivo by Malassezia yeasts has not been described before. Masson-Fontana staining confirmed accumulation of black pigment on the cell walls of L-dihydroxyphenylalaline (L-DOPA)-cultured Malassezia species. Black pigment was also observed in cells and hyphae from hyperpigmented patient lesions with culture-confirmed pityriasis versicolor and seborrhei...

We experienced an atypical case of pityriasis versicolor with a unique clinical appearance and undescribed mycological features. Although Malassezia sp. was cultured from the keratotic material, the fungal elements observed in the material were not readily identified as Malassezia. The diagnosis was established with the aid of immunohistochemical and ultrastructural studies with the aetiologica...

The authors report a case of pityriasis versicolor circinata whose isolated etiologic agent was Malassezia sympodialis in a 34-year-old woman. The isolation and identification of Malassezia sympodialis were accomplished with modified Dixon's agar, and the molecular method used to confirm the species was polymerase chain reaction and restriction fragment length polymorphism analysis (PCR-RFLP).

conclusions patients who regularly use the local saunas had poor personal hygiene and greasy skin, and were more suspected to tinea versicolor infection. results the disease was more prevalent in 21-40 years old age group in both genders. the most infected anatomical regions were posterior surface, the body trunk (shoulder, supra scapula and lumbar region), anterior thorax and abdomen, respecti...
