Methodological Issues in Antifungal Susceptibility Testing of Malassezia pachydermatis

Methodological Issues in Antifungal Susceptibility Testing of Malassezia pachydermatis

Reference methods for antifungal susceptibility testing of yeasts have been developed by the Clinical and Laboratory Standards Institute (CLSI) and the European Committee on Antibiotic Susceptibility Testing (EUCAST). These methods are intended to test the main pathogenic yeasts that cause invasive infections, namely Candida spp. and Cryptococcusneoformans, while testing other yeast species int...

Antifungal susceptibility of Malassezia pachydermatis biofilm.

Antifungal resistance has been associated with biofilm formation in many microorganisms, but not yet in Malassezia pachydermatis. This saprophytic yeast can cause otitis and dermatitis in dogs and has emerged as an important human pathogen, responsible for systemic infections in neonates in intensive care units. This study aims to evaluate the in vitro antifungal susceptibility of M. pachyderma...

Issues in antifungal susceptibility testing.

In line with the availability of an increasing array of systemic antifungal agents, there is a need for accurate, reproducible and predictive susceptibility testing of fungal isolates in order to help inform clinical choice. Much early attention on antifungal susceptibility testing focused on defining test parameters that produced reproducible and reliable intra- and inter-laboratory results an...

Susceptibility variation of Malassezia pachydermatis to antifungal agents according to isolate source

Malassezia pachydermatis is associated with dermatomycoses and otomycosis in dogs and cats. This study compared the susceptibility of M. pachydermatis isolates from sick (G1) and healthy (G2) animals to azole and polyene antifungals using the M27-A3 protocol. Isolates from G1 animals were less sensitive to amphotericin B, nystatin, fluconazole, clotrimazole and miconazole.
