The frequencies of isolation and population sizes of Malassezia spp. on skin and at mucosal sites in 16 cats with diabetes mellitus, 20 cats with hyperthyroidism and 8 cats with neoplasia did not vary significantly from those of healthy cats when measured with the use of contact plates and a swab technique. M. pachydermatis was isolated from nine sites in one cat with feline paraneoplastic alop...

Pityriasis versicolor (PV) is a common clinical problem associated with Malassezia species (Malassezia spp.). Controversies remain regarding the specific species involved in the development of PV. This study analyzed the difference in Malassezia spp. distribution in lesional and nonlesional skin in Chinese PV patients. A paired design was applied. Lesional and nonlesional scales from 24 cases w...

the present study is designed to evaluate the application of a simple method for rapid identification of malassezia furfur among other malassezia spp. based on production of a brownish-red pigment and its diffusion into the medium containing l-tryptophan as a sigle source of nitrogen.  91 strains of malassezia (20% m. furfur , 2% m. sympodialis , 5% m. obtosa and 73% m. globosa ) isolated from ...

The objective of this study was to characterize genotypically Malassezia spp. isolated from the external ear canal of healthy horses. Fifty-five horses, 39 (70.9%) males and 16 (29.1%) females, from different breeds and adults were studied. External ear canals were cleaned and a sterile cotton swab was introduced to collect cerumen. A total of 110 samples were cultured into Dixon medium and wer...

It is a multifactorial disease that requires several predisposing factors for its progress. Presence of these factors leads to reproduction of opportunistic yeast Malassezia spp [2]. The fungus uses lipids from the skin surface to produce unsaturated and saturated fatty acids which, when left in the individual’s skin milieu, induce an inflammatory response. The sebum in the skin aids the growth...

Although the lipophilic yeasts of the genus Malassezia are part of the cutaneous microbiota in healthy individuals, they are also associated with several skin diseases, such as seborrheic dermatitis. However, the effects of age and gender on the Malassezia microbiota have not been completely elucidated. We analyzed the cutaneous Malassezia microbiota of 770 healthy Japanese using the highly acc...

the lipophilic yeasts of malassezia species are members of the normal skin microbial that are cause of pityriasis versicolor. pityriasis versicolor is a common superficial fungal infection with world-wide distribution. the phenotypic methods for identification of malassezia species usually are time consuming and unreliable to differentiate newly identified species. but dna-based techniques rapi...
