We will perform ultra-deep sequencing of your microbiome sample aimed at generating as many individual
bacterial genomes as possible (we can't tell you how because the details of the technique are still under wraps prior to publication).

Overlapping «cassettes» of 5 to 7 kilobases (kb), assembled from chemically synthesized oligonucleotides, were joined by in vitro recombination to produce intermediate assemblies of approximately 24 kb, 72 kb («1/8

bacterial genomes, and the yeast
genome project, known
as Sc2.0, aims to have all 16 chromosomes — roughly 10 million base pairs — assembled by the end of next year.
The
bacterial genomes come from species that challenge the technical performance of sequencing methods and have been determined by the Food and Drug Administration (link is external)(FDA) to have significant relevance to the research of public health issues such
as food contamination, antibiotic resistance and hospital - acquired infections.
Sequencing the
genome allowed researchers to identify the gene for lysin, an enzyme that the virus uses to kill
bacterial cells, that has potential use
as an antibiotic or disinfecting agent.
During their coexistence, the bacterium was further and further integrated
as a power plant into the cell, which was evident in the fact that the construction plans of the power plant were increasingly transferred into the host cell from the
bacterial genome.
The study results were very surprising: For most of these clinical measures, the association with
bacterial genomes was at least
as strong, and in some cases stronger, than the association with the host's human
genome.
I will review recent advances in the use of nanopore sequencing for clinical microbiology and human genetics, including our collaborations on viral and
bacterial diagnostic sequencing, real - time surveillance, direct RNA and human whole -
genome sequencing, and discuss the opportunities and barriers around moving to sequencing
as a routine test in the clinic.
