WebHere, we present a gut phage isolate collection (GPIC) containing 209 phages for 42 commensal human gut bacterial species. Genome analysis of the phages identified 34 undescribed genera. We discovered 22 phages from the Salasmaviridae family that have small genomes (∼10–20 kbp) and infect Gram-positive bacteria. WebThe viral count would be 200/20 x 5 x 10 10 /ml = 5 x 10 11 /ml. The concentration of viruses in a sample is also known as its titre. Among the other methods for assay of viral titres in a sample, the plaque method is a very important one. It makes use of the infectivity of the viruses and their capacity to destroy the infected cells.
