Oral microbiome of the inner surface of face masks and whole saliva during the COVID-19 pandemic.

Wearing a face mask was strongly recommended during the COVID-19 pandemic. The purpose of this study was to investigate the diversity of the oral microbiome, the abundance of each bacterium on the inner surface of the mask, and the effects of xerostomia on the microbiota.

Volatile sulfide compounds and oral microorganisms on the inner surface of masks in individuals with halitosis during COVID-19 pandemic.

Mask-wearing is still recommended owing to the continuing impact of the COVID-19 pandemic. Within the closed chamber created by the mask, people are increasingly self-aware of their oral malodor. In this prospective and cross-sectional study, we aimed to measure volatile sulfide compound (VSC) levels in patients with halitosis and investigate the oral microbiome profile on the inner surface of their KF94 masks.

Eucalyptus.

Using Eucalyptus camaldulensis as a model system, we describe here a basic Agrobacterium-mediated genetic transformation protocol through organogenesis for the production of transgenic plants. Hypocotyl segments or cotyledon pieces from in vitro seedlings are used as starting materials. The explants are inoculated and cocultivated with a disarmed, binary strain of A.
