Abstract

During the COVID-19 pandemic, facemasks played a pivotal role in preventing person-person droplet transmission of viral particles. However, prolonged facemask wearing causes skin irritations colloquially referred to as 'maskne' (mask + acne), which manifests as acne and contact dermatitis and is mostly caused by pathogenic skin microbes. Previous studies revealed that the putative causal microbes were anaerobic bacteria, but the pathogenesis of facemask-associated skin conditions remains poorly defined. We therefore characterized the role of the facemask-associated skin microbiota in the development of maskne using culture-dependent and -independent methodologies. Metagenomic analysis revealed that the majority of the facemask microbiota were anaerobic bacteria that originated from the skin rather than saliva. Previous work demonstrated direct interaction between pathogenic bacteria and antagonistic strains in the microbiome. We expanded this analysis to include indirect interaction between pathogenic bacteria and other indigenous bacteria classified as either 'pathogen helper (PH)' or 'pathogen inhibitor (PIn)' strains. In vitro screening of bacteria isolated from facemasks identified both strains that antagonized and promoted pathogen growth. These data were validated using a mouse skin infection model, where we observed attenuation of symptoms following pathogen infection. Moreover, the inhibitor of pathogen helper (IPH) strain, which did not directly attenuate pathogen growth in vitro and in vivo, functioned to suppress symptom development and pathogen growth indirectly through PH inhibitory antibacterial products such as phenyl lactic acid. Taken together, our study is the first to define a mechanism by which indirect microbiota interactions under facemasks can control symptoms of maskne by suppressing a skin pathogen.

通过调节微生物组的间接相互作用来减少面罩粉刺。
在 COVID-19 大流行期间,口罩在防止病毒颗粒的人际飞沫传播方面发挥了关键作用。然而,长时间佩戴口罩会导致皮肤过敏,俗称 "口罩+痤疮",表现为痤疮和接触性皮炎,主要由致病性皮肤微生物引起。以前的研究显示,可能的致病微生物是厌氧菌,但面膜相关皮肤病的发病机理仍未明确。因此,我们采用依赖培养和不依赖培养的方法,研究了面膜相关皮肤微生物群在面膜痤疮发病过程中的作用。元基因组分析表明,大部分面罩微生物群是厌氧菌,它们来自皮肤而非唾液。以前的研究表明,致病菌与微生物群中的拮抗菌株之间存在直接相互作用。我们扩大了这一分析范围,将致病菌与被归类为 "病原体辅助菌株(PH)"或 "病原体抑制菌株(PIn)"的其他本地细菌之间的间接相互作用也包括在内。对从面膜中分离出来的细菌进行体外筛选,发现了拮抗和促进病原体生长的菌株。我们利用小鼠皮肤感染模型对这些数据进行了验证,观察到病原体感染后症状减轻。此外,病原体辅助菌株抑制剂(IPH)在体外和体内都不能直接抑制病原体的生长,但它能通过 PH 抑制抗菌产物(如苯乳酸)间接抑制症状的发展和病原体的生长。综上所述,我们的研究首次明确了面罩下间接微生物群相互作用可通过抑制皮肤病原体来控制面罩症状的机制。

期刊介绍: npj Biofilms and Microbiomes is a comprehensive platform that promotes research on biofilms and microbiomes across various scientific disciplines. The journal facilitates cross-disciplinary discussions to enhance our understanding of the biology, ecology, and communal functions of biofilms, populations, and communities. It also focuses on applications in the medical, environmental, and engineering domains. The scope of the journal encompasses all aspects of the field, ranging from cell-cell communication and single cell interactions to the microbiomes of humans, animals, plants, and natural and built environments. The journal also welcomes research on the virome, phageome, mycome, and fungome. It publishes both applied science and theoretical work. As an open access and interdisciplinary journal, its primary goal is to publish significant scientific advancements in microbial biofilms and microbiomes. The journal enables discussions that span multiple disciplines and contributes to our understanding of the social behavior of microbial biofilm populations and communities, and their impact on life, human health, and the environment.
