Aim: The role of intestinal fungi in human health and disease is becoming more evident. mycobiota composition diversity preterm infants affected by interactions with bacteria clinical variables. In this study, we aimed to characterize the infant effect variables on it first six postnatal weeks. Methods: Preterm (n = 50) full-term 6) admitted Isala Women Children’s hospital (Zwolle, Netherlands)...

background malassezia species as skin microflora of humans and other warm-blooded vertebrates are the lipophilic yeasts associated with various human diseases, especially pityriasis versicolor (pv). objectives the objective of this study was to identify the malassezia species of scraped skin of pv patients in yazd, iran, using morphological, biochemical and physiological methods. we also compar...

BACKGROUND Skin pigmentary changes of pityriasis versicolor may occur as either hyperpigmented or hypopigmented lesions, depending on the outcome of interactions between Malassezia yeasts and the skin, such as lipoperoxidation process, stimulus of inflammatory cell to melanocytes, and increased thickness of keratin layer. OBJECTIVE To investigate skin characteristic factors that enhance the s...

The implication of the yeast genus Malassezia in skin diseases has been characterized by controversy, since the first description of the fungal nature of pityriasis versicolor in 1846 by Eichstedt. This is underscored by the existence of Malassezia yeasts as commensal but also by their implication in diseases with distinct absence of inflammation despite the heavy fungal load (pityriasis versic...

The role of the fungal community, mycobiota, in health vagina is currently an important area research. emergence new sequencing technologies and advances bioinformatics made possible discovery novel fungi inhabiting this niche. Candida spp. constitutes most group opportunistic pathogenic fungi, being prevalent species vulvovaginal infections. However, such as Rhodotorula spp., Naganishia Malass...

A wide variety of bacteria and fungi are found on the human skin. Although some skin microorganisms produce antibacterial peptides that inhibit invasion by pathogens or promote the integrity of cutaneous defenses by eliciting host immune responses, the normal microbiome can also cause several skin diseases. Atopic dermatitis (AD) is a chronic disease that causes pruritus and involves cycles of ...

Dandruff, a skin disorder affecting 50% of the world population, is linked with proliferation of lipophilic yeasts of the genus Malassezia (particularly Malassezia globosa and M. restricta). Most Malassezia species show a unique lipid dependency and require external lipids for growth. Genome mining of the incomplete M. restricta genome led to the identification of eight lipase sequences. Sequen...

A comparison of several media, i.e., potato dextrose agar with olive oil (Oil-PDA), modified Dixon agar (mDIX) and variations of Leeming and Notman agar (LNA) for the isolation and growth of Malassezia and Candida species was examined. Since LNA supported the highest growth of Malassezia species its key components, i.e., ox bile, glycerol monostearate, glycerol and Tween 60, were added to CHROM...

The skin surface varies topographically owing to regional differences in skin anatomy and, according to culture-based studies, these regions are known to support distinct sets of microorganisms [1]. Regions with higher temperature and humidity encourage growth of Gram-negative bacilli, coryneforms and Staphylococcus aureus, whereas areas with high density of sebaceous glands encourage growth of...

BACKGROUND The pathogenesis of androgenic alopecia is not fully understood. A microbial-driven inflammatory reaction abutting on the hair follicles might participate in the hair status anomaly. OBJECTIVE The aim of our study was to determine if ketoconazole (KCZ) which is active against the scalp microflora and shows some intrinsic anti-inflammatory activity might improve alopecia. METHOD T...
