A Bayesian approach to differential prevalence analysis with applications in microbiome studies
Recent evidence suggests that analyzing the presence/absence of taxonomic features can offer a compelling alternative to differential abundance analysis in microbiome studies. However, standard approa...

1/ 🚨 New preprint alert! 🚨 We’re thrilled to share our latest work exploring microbiome & genomic #Bifidobacterium co-evolutionary & functional signatures across diverse animal hosts. This has been a long time coming, & huge credit to Magda for her incredible hard work as first author! 🐾✨👇
Host-specific microbiome and genomic signatures in Bifidobacterium reveal co-evolutionary and functional adaptations across diverse animal hosts
Animal hosts harbour divergent microbiota, including various Bifidobacterium species and strains, yet their evolutionary relationships, and functional adaptions remain understudied. By integrating tax...

Fascinating Insights here 👇 50% of all bacteriology papers focus on just 10 species, a disproportionate emphasis on pathogens. Narrow focus hinders the development of novel health promoting microbes. #microbiome www.biorxiv.org/content/10.1...
Ten species comprise half of the bacteriology literature, leaving most species unstudied
Microbiology research has historically focused on a few species of model organisms. Our bibliographic analysis finds extreme bias in the distribution of bacteriology research across species, with half...
