Studies showing the association of Malassezia with psoriasis.

Psoriasis Patients (PP) and/or Controls	Samples	Methods	Malassezia	References
22 PP vs. 30 healthy subjects (HS)	lesional and non-lesional skin	Nested PCR	High detection (64–96%) in PP Species diversity (3.7 ± 1.6 in PP vs. 2.8 ± 0.8 in HS)	[15]
50 PP vs. 50 HS	lesional and non-lesional skin	Culture/ITS2 PCR-RFLP and D1/D2 sequencing	68% of PP cases vs. 60% of HS In PP, more colonies isolated in psoriatic lesions (53 colonies) than in non-lesional skin (19), especially on the scalp (p = 0.03). High species richness in PP than HS	[16]
34 PP vs. 25 HS	skin lesion and non-lesion	ITS1 metabarcoding	A significantly higher abundance of M. restricta and M. sympodialis in psoriatic lesions than HS	[18]
