Malassezia pachydermatis is the most common cause of yeast dermatitis and otitis in dogs and cats.

Normally present in low numbers, Malassezia can overpopulate and become pathogenic under certain conditions and cause external otitis and severe itchy dermatitis.  Accurate diagnosis is important as excessive numbers is always linked to an underlying condition.  Atopic dermatitis is the most common predisposing factor for M. pachydermatis infection.  Approximately one third of dogs with atopic dermatitis are reported to have concurrent Malassezia dermatitis.

Along with clinical examination, cytology and fungal culture are methods of diagnosis.  Cytology is reported to be highly specific, but with low sensitivity leading to false negative results.  Traditional culture testing is complex and lengthy.  In both, interpretation of results is complicated as the minimum number of colonies indicating infection is not standardized.

RapidVet®-M is a ready-to-use culture test specific for detection of Malassezia.  It looks like conventional culture media, but it is different! 

RapidVet®-M is the only test that enables identification of Malassezia spp. without the use of a microscope.

        •Specific chromogenic substrate in the media reacts with specific yeast enzymes causing rounded pink, dark pink or violet colonies           to form generally within 48 hours of inoculation.
        •High sensitivity and specificity for accurate identification of the pathogenic species enabling prompt and targeted therapy.

        •In-office test requires only a small incubator.
