Is Malassezia a commensal?

Malassezia normally exist as a skin commensal without inflicting disease, suggestive of contextual pathogenesis. One possible mechanism of Malassezia mediated skin disease is host genetic susceptibility (Deangelis et al., 2005).

What causes Psoroptes Cuniculi in rabbits?

Psoroptes cuniculi mites are just visible to the naked eye (see Figure 14.1). The mite is transmitted by direct contact between rabbits. Crusts dislodge into the environment and contain many mites that can survive for up to 21 days off the host.

Is Malassezia a dermatophyte?

Less frequently, superficial skin infections are caused by nondermatophyte fungi (e.g., Malassezia furfur in tinea [pityriasis] versicolor) and Candida species. This article reviews the diagnosis and treatment of common dermatophyte infections.

Can rabbit ear mites bite humans?

But dust mites don’t bite humans. They also don’t live on humans, though they can sometimes get onto your clothing. Dust mites can, however, cause allergic reactions.

What triggers Malassezia yeast?

The Malassezia (antigen) proteins are found in sweat and the disease is therefore triggered by sweating (sometimes referred to as sweat allergy) (Hiragun et al., 2013; Maarouf et al., 2018).

Is Malassezia a pathogen?

Over the last decade, new tools for Malassezia culture, detection, and genetic manipulation have revealed not only the ubiquity of Malassezia on skin but new pathogenic roles in seborrheic dermatitis, psoriasis, Crohn’s disease, and pancreatic ductal carcinoma.

Can humans get Psoroptes cuniculi?

cuniculi). Psoroptic mites from horses have not been reported to cause disease in humans.

How do you treat Psoroptes cuniculi in rabbits?

This mite is treated by cleaning the external ear canal, removing any debris or discharge, followed by instillation of an otic preparation with activity against this ear mite.

Are dermatophytes yeast or mold?

Dermatophytes belong to the mold group of fungi and cause cutaneous infections. Although specific organisms usually cause dermatophyte infections in particular parts of the body, dermatophyte diseases are usually classified according to site of infection, and are often referred to as tinea.
