Metagenomic studies have predominantly focused on characterising the bacterial constituents of the human gut microbiome, but in recent years there has been a growing focus on its bacteriophage components. Using next generation sequencing, we have examined the faecal viromes of two human cohorts at the extremes of life. Infant (n=20; 1 y.o.) and elderly (n=20, 67-93 y.o.) faecal samples were selected to incorporate individuals delivered by natural or caesarean birth, and residing in the community or long-stay residential care, respectively. An average of approx. 1.0 M Illumina MiSeq 2x300 bp reads were obtained per sample. Taxonomic classification of viral reads was performed against an in-house viral database constructed from public databases and relevant publications to determine if differences exists between the two cohorts. Principle coordinate analysis (PCoA) of viral taxa supported the clustering of the samples based on biological factors, including age and birth mode. Differential abundance analysis of viruses identified prevalent taxa and variations between the two cohorts, such as the human gut-associated virus crAssphage. Finally, the accessory functional genetic repertoire associated with the viromes was characterised, including virulence factors and antibiotic resistance genes. Studies investigating phages and viruses associated with the human gastrointestinal tract are important to improve our understanding of this important ecosystem that is so closely associated with human health.
