Abstract

<h4>Purpose</h4>This study aims to explore and characterize healthy eye microbiota.<h4>Methods</h4>Healthy subjects older than 18 years were selected for this descriptive cross-sectional study. Samples were collected with an eSwab with 1 mL of Liquid Amies Medium (Copan Brescia, Italy). Following DNA extraction, libraries preparation, and amplification, PCR products were purified and end-repaired for barcode ligation. Libraries were pooled to a final concentration of 26 pM. Template preparation was performed with Ion Chef according to Ion 510, Ion 520, and Ion 530 Kit-Chef protocol. Sequencing of the amplicon libraries was carried out on a 520 or 530 chip using the Ion Torrent S5 system (Thermo Fisher; Waltham, MA, USA). Raw reads were analyzed with GAIA (v 2.02).<h4>Results</h4>Healthy eye microbiota is a low-diversity microbiome. The vast majority of the 137 analyzed samples were highly enriched with <i>Staphylococcus</i>, whereas only in a few of them, other genera such as <i>Bacillus, Pseudomonas,</i> and <i>Corynebacterium</i> predominate. We found an average of 88 genera with an average Shannon index of 0.65.<h4>Conclusion</h4>We identified nine different ECSTs. A better understanding of healthy eye microbiota has the potential to improve disease diagnosis and personalized regimens to promote health.
