Dispersion characteristics of oral microbial communities in a built environment

Advances in next-generation sequencing (NGS) technologies since 2005 have revolutionized biological science. One particular application of NGS is to elucidate microbiomes built environments. We are currently conducting a series studies on the elucidation and control mass infection mechanisms based dynamic measurement environment microbiomes. The objective this study clarify dispersion characteristics oral bacteria environment. Bacterial communities from occupants’ hands cavities, doorknobs, desk keyboard surfaces, air laboratories were investigated seven Japanese universities. median relative abundances Firmicutes, Proteobacteria, Actinobacteria, Bacteroidetes, Fusobacteria 41%, 31%, 12%, 7%, 3%, respectively. Moreover, main genera detected Streptococcus (27.6%), Haemophilus (7.0%), Staphylococcus (5.6%), Neisseria Corynebacterium (4.7%), Rothia (3.2%), Prevotella (3.0%), Fusobacterium (2.6%), Veillonella (1.7%), Leptotrichia Enhydrobacter Lactobacillus (1.3%), Acinetobacter Actinomyces (1.1%). Actinomyces, Corynebacterium, Fusobacterium, Haemophilus, Leptotrichia, Neisseria, Prevotella, Rothia, observed indoor surfaces as well cavities. Furthermore, melaninogenica mucilaginosa all samples, including those PC laboratories,
