Malassezia pachydermatis: a review
1Unité de Parasitologie-Mycologie, UMR Biologie Moléculaire et Immunologie Parasitaires et Fongiques, Ecole Nationale Vétérinaire d'Alfort, Maisons-Alfort, France. j.guillot@vet-alfort.fr
Abstract:
Malassezia pachydermatis is of importance in both veterinary and human medicine. Its taxonomic status and physiological characteristics are now better understood. Skin disease associated with this lipophilic yeast is now commonly recognized, especially in dogs. However, further studies are required to elucidate the mechanisms which allow this yeast to proliferate and induce disease. Skin colonization is common in pet carnivores which consequently constitute a source of M. pachydermatis for susceptible humans. In the future, the development of efficient typing systems should allow better understanding of the transmission mechanisms.
Insights
Malassezia pachydermatis yeast causes skin disease in dogs and humans. Further research is needed to understand how this yeast spreads and causes infections.
Area of Science:
- Veterinary Dermatology
- Medical Mycology
- Microbiology
Background:
- Malassezia pachydermatis is a lipophilic yeast significant in veterinary and human medicine.
- The yeast's taxonomy and physiology are increasingly understood.
- Skin conditions linked to Malassezia pachydermatis are frequently diagnosed, particularly in canines.
Purpose of the Study:
- To review the current understanding of Malassezia pachydermatis.
- To highlight the need for further research into the yeast's proliferation and pathogenicity mechanisms.
- To emphasize the role of pet carnivores as reservoirs for human infections.
Main Methods:
- Literature review and synthesis of existing research on Malassezia pachydermatis.
- Analysis of current knowledge regarding yeast characteristics and associated diseases.
- Discussion of epidemiological links between animal and human infections.
Main Results:
- Malassezia pachydermatis is a recognized cause of skin disease, especially in dogs.
- Pet carnivores frequently harbor the yeast, posing a transmission risk to humans.
- Understanding transmission mechanisms requires further investigation.
Conclusions:
- Malassezia pachydermatis is an important yeast with implications for both animal and human health.
- Elucidating the mechanisms of yeast proliferation and disease induction is crucial.
- Development of robust typing systems is essential for understanding transmission dynamics.
