Malassezia pachydermatis is a basidiomycetous yeast that causes infections in humans and animals. Here, we report the genome sequence of Malassezia pachydermatis strain CBS 1879, which will facilitate the study of mechanisms underlying pathogenicity of the only non-lipid-dependent Malasezzia species.
During a survey of the occurrence of Malassezia species in the external ear canals of dogs with chronic otitis externa, lipid-dependent Malassezia species were isolated in three dogs. These species were identified as Malassezia furfur and M. obtusa but showed atypical assimilation patterns. To our knowledge, this is the first report of the isolation of lipid-dependent species of the genus Malas...
Malassezia is a unique lipophilic genus in class Malasseziomycetes in Ustilaginomycotina, (Basidiomycota, fungi) that otherwise consists almost exclusively of plant pathogens. Malassezia are typically isolated from warm-blooded animals, are dominant members of the human skin mycobiome and are associated with common skin disorders. To characterize the genetic basis of the unique phenotypes of Ma...
Experience with a MicroSeq D2 large-subunit (LSU) ribosomal DNA (rDNA) sequencing kit for identification of yeast species commonly encountered in the mycology laboratory at Mayo Clinic is described here. A total of 131 isolates of yeasts recovered from clinical specimens were included in the study. Phenotypic methods used for initial identification included germ tube formation, urease productio...
There is cumulative resistance against antibiotics of many bacteria. Therefore, the development of new antiseptics and antimicrobial agents for the treatment of skin infections is of increasing interest. We have screened six plant extracts and isolated compounds for antimicrobial effects on bacteria and yeasts with dermatological relevance. The following plant extracts have been tested: Gentian...
The genus Malassezia includes yeasts that are commonly found on the skin or hair of animals and humans as commensals and are associated with a number of skin disorders. We have previously developed an Agrobacterium tumefaciens transformation system effective for both targeted gene deletion and insertional mutagenesis in Malassezia furfur and M. sympodialis In the present study, these molecular ...
As the dominant component of the mycobiota on human skin [1] —both healthy and diseased [2] —the genus Malassezia has received a fair amount of attention. Since the middle of the 19th century, researchers have linked these fungi with skin maladies such as dandruff and eczema [3], but their difficulty to culture axenically long hampered studies of their systematics and diversity [4]. Malassezia ...
The aim of the study was the isolation of genus Malassezia species in healthy dogs, and their identification since there are ten known species and their number increases every year. Dixon medium is considered to be the best for Malassezia isolation, and the results of the study proved to be so. Of all the 74 Malassezia strains isolated, 71 were M. pachydermatis, 2 M. furfur and one M. globosa. ...
Malassezia is a lipophilic fungus which has different species. Some of them can be found as a natural flora on skin and in an opportunistic condition may cause pityriasis versicolor. The present study was undertaken to identify, diagnose and determine the prevalence of different species of malassezia in patients referred to laboratory of medical mycology at the University of Shiraz during 1...
Malassezia spp. form part of the normal human cutaneous flora and are implicated in several mild, but recurrent cutaneous diseases, such as pityriasis versicolor, Malassezia folliculitis, seborrhoeic dermatitis, and, with lesser frequency, a range of other dermatological disorders. Malassezia spp. have also been associated with cutaneous and systemic diseases in immunocompromised patients inclu...
