Skin fungal community and its correlation with bacterial community of urban Chinese individuals

Skin constantly encounters external elements, including microbes. Culture-based studies have identified fungi present on human skin and have linked some species with certain skin diseases. Moreover, modern medical treatments, especially immunosuppressants, have increased the population at risk for cutaneous and invasive fungal infections, emphasizing the need to understand skin fungal communities in health and disease. A major hurdle for studying fungal flora at a community level has been the heterogeneous culture conditions required by skin fungi. Recent advances in DNA sequencing technologies have dramatically expanded our knowledge of the skin microbiome through culture-free methods.

Understanding the skin mycobiome fungal communities is important because both commensal and pathogenic fungi can drive cutaneous disease depending on host status and body sites, including the scalp, feet, and groin. Interestingly, age may also affect skin fungal infections as certain dermatophytoses i. We previously described the skin mycobiomes in healthy adults, showing lipophilic fungi Malassezia predominate in most skin sites. Since children have less sebaceous skin before puberty, we compared the fungal communities of primary clinical samples from healthy children and adults, based on sequencing of a fungal phylogenetic marker. Species-level classification showed M.

Skin protects humans from invasion by pathogenic microorganisms and provides a home for diverse commensal microbiota 1. Bacterial genomic sequence data have generated novel hypotheses about species and community structures underlying human disorders 2 , 3 , 4. However, microbial diversity is not limited to bacteria; microorganisms such as fungi also have major roles in microbial community stability, human health and disease 5.

Metrics details. High-throughput sequencing has led to increased insights into the human skin microbiome. Currently, the majority of skin microbiome investigations are limited to characterizing prokaryotic communities, and our understanding of the skin fungal community mycobiome is limited, more so for cohorts outside of the western hemisphere. Here, the skin mycobiome across healthy Chinese individuals in Hong Kong are characterized. Based on a curated fungal reference database designed for skin mycobiome analyses, previously documented common skin colonizers are also abundant and prevalent in this cohort. However, genera associated with local terrains, food, and medicine are also detected.

Traditional culture-based methods have incompletely defined the microbial landscape of common recalcitrant human fungal skin diseases, including athlete's foot and toenail infections. Skin protects humans from invasion by pathogenic microorganisms and provides a home for diverse commensal microbiota. Bacterial genomic sequence data have generated novel hypotheses about species and community structures underlying human disorders. However, microbial diversity is not limited to bacteria; microorganisms such as fungi also have major roles in microbial community stability, human health and disease.

Ему вдруг страшно захотелось увидеть ее - сейчас. Прохладный ветерок кондиционера напомнил ему о жаре на улице. Он представил себе, как бредет, обливаясь потом, по душным, пропитанным запахом наркотиков улицам Трианы, пытаясь разыскать девчонку-панка в майке с британским флагом на груди, и снова подумал о Сьюзан. - Zumo de arandano, - с удивлением услышал он собственный голос.

Беккер еще раз обвел глазами кучу вещей и нахмурился. Зачем АНБ вся эта рухлядь. Вернулся лейтенант с маленькой коробкой в руке, и Беккер начал складывать в нее вещи. Лейтенант дотронулся до ноги покойного. - Quien es. Кто он .

 Так записано в его медицинской карточке. Он не очень-то об этом распространялся. Сьюзан трудно было поверить в такое удачное совпадение. - Его погубило слабое сердце - вот так. Слишком уж удобная версия. Стратмор пожал плечами. - Слабое сердце… да к тому же еще испанская жара.

 - Танкадо утверждал, что это составная часть кода.  - И он безжизненно откинулся на спинку стула. Сьюзан была понятна боль, которую испытывал шеф. Его так просто обвели вокруг пальца.

 Но, Сьюзан… я думал… - Он взял ее за дрожащие плечи и повернул к. И тогда он увидел, что Сьюзан вовсе не плакала. - Я не выйду за тебя замуж! - Она расхохоталась и стукнула его подушкой.  - До тех пор, пока ты не объяснишь, что такое без воска. Ты сводишь меня с ума.

Очевидно, директор что-то скрывает, но Бринкерхоффу платили за то, чтобы он помогал, а не задавал вопросы. Фонтейн давно всем доказал, что близко к сердцу принимает интересы сотрудников. Если, помогая ему, нужно закрыть на что-то глаза, то так тому и .
