SARS-CoV-2 Titers in Wastewater Are Higher than Expected from Clinically Confirmed Cases.

abstract：:As the most ancient metazoan, sponges have established close relationships with particular microbial symbionts. However, the characteristics and physiology of thioautotrophic symbionts in deep-sea sponges are largely unknown. Using a tailored "differential coverage binning" method on 22-Gb metagenomic sequences, we re...
