I would like to sequence genomes from 2 different organisms using Illumina Miseq. one is Staph. aureus of about 2.8Mbp and the other is a virus of about 13Kb. Is it okay to pool this samples after library preparation and run them in one flow cell? What are the pros and cons?

Sure. You will need to index (tag) the samples so the reads can be separate after the run. -
Yes, I will index the samples, but I was wondering if there is any effect of having different sizes of genomes pooled together. Will the larger be 'sequenced more' than the smaller or will they get equal representation in the final output? Is there a cut-off of or guideline of what kinds of genomes you can pool together?
I am new at this so it may seem like a silly question...Comment

The number of reads for each library is dependent on loading not the genome size. Pooling libraries with same fragment length distribution should output reads in proportion to loading. If the library (not genome) sizes are different, then with equal loading more of shorter libraries will be sequenced.
You can pool many types of libraries in one run if the sequencing configuration is similar.Comment

NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification, detection...Yesterday, 06:46 AM -
Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?
Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating...10-14-2026, 09:55 AM
