“…There can also be a relationship between the AD-affected body part and the prevalent yeast genera: if Malassezia mostly colonize lipid-rich areas; Candida usually appear on hands and legs. The data obtained in the present study are similar to those from previous studies [10,14,40]. In the child group, the yeast colonization rate was significantly lower than in the adult group.…”

“…With regard to non-Malassezia fungi, this finding is not surprising, given that healthy skin forms a physical barrier with many defensive strategies, and that transient or commensal yeasts from the environment are incapable of surviving on an intact skin for long periods of time. Malassezia yeasts are members of the normal human cutaneous flora and are found on the skin of healthy adults [9,40]. In the present study, we observed no Malassezia growth in the control group and, in general, colonization with these yeasts was very low as compared with other studies.…”

AbstractThe skin of persons with atopic dermatitis (AD) is very susceptible to cutaneous infection, and some yeast species may also aggravate AD. The total yeast population of an AD patient’s skin and its relation with individual age and body part remains poorly characterized. The aim of this study was to clarify the differences in cutaneous yeast flora by age and body parts of AD patients.By swabbing affected body parts (hands, legs, face, neck or trunk), 241 samples were collected from patients with AD (132 children and 109 adults), and as controls, 40 samples were taken from healthy individuals (20 children, 20 adults).In all, 89 (36.9%) of samples were positive; the yeast isolated belonged to three genera: Candida (27.4%), Malassezia (6.6%), and Rhodotorula (2.9%). Cutaneous colonization with yeasts was two-fold higher in the adults than in children (P<0.0001). The distribution of the yeast species was dependent on the body part sampled: Malassezia predominated in the face, neck, and trunk regions (P=0.0047); Candida more frequently colonized hands and legs (P=0.0029).Our study showed that cutaneous yeast flora and distribution of yeast species depends significantly on the age of the AD patient and the body part affected by atopic dermatitis.

Objectives: We investigated the facial skin microbiota of Japanese acne patients. Methods: Skin swab samples were obtained from 100 acne patients and 28 healthy controls to evaluate Propionibacterium and Staphylococcus spp. using a culture method. Malassezia spp. were evaluated using a nonculture method. Antibiotic resistance of Propionibacterium spp. was also examined. Results: Acne patients and controls did not show significant differences in Propionibacterium and Staphylococcus spp. populations. However, the number of Malassezia globosa from patients was greater than that from controls. Moreover, the number of Propionibacterium spp. from patients carrying antibiotic-resistant strains was significantly greater than that from patients not carrying them. Conclusions: The present study characterized the facial skin microbiota of Japanese acne patients, suggesting a correlation between acne and quantitative differences in Malassezia microbiota. It was also found that the antibiotic resistance of Propionibacterium spp. may affect its abundance in the skin.

“…In all, no significant differences were observed between the bacterial communities of males and females regardless of age group. Moreover, a study comparing the levels of Propionibacterium and coagulase negative Staphylococcus in middle-aged men and women found no significant differences at the forehead, cheek, upper chest, or back [33]. However, it was found that males harbored greater total amounts of the fungi Malassezia .…”

The skin is colonized by an assemblage of microorganisms which, for the most part, peacefully coexist with their hosts. In some cases, these communities also provide vital functions to cutaneous health through the modulation of host factors. Recent studies have illuminated the role of anatomical skin site, gender, age, and the immune system in shaping the cutaneous ecosystem. Alterations to microbial communities have also been associated with, and likely contribute to, a number of cutaneous disorders. This review focuses on the host factors that shape and maintain skin microbial communities, and the reciprocal role of microbes in modulating skin immunity. A greater understanding of these interactions is critical to elucidating the forces that shape cutaneous populations and their contributions to skin homeostasis. This knowledge can also inform the tendency of perturbations to predispose and/or bring about certain skin disorders.
