Stochastic colonization and host-to-host transmission shape gut bacterial variability

Carol Yunxiao Lu, Stanimir Asenov Tashev, Pedro Pessoa, Rory Kruithoff, Douglas P. Shepherd, Steve Pressé

This study shows that stochastic colonization and host-to-host transmission significantly influence gut bacterial variability in C. elegans using E. coli under different diets.

GPU-accelerated, self-optimizing processing for 3D multiplexed iterative RNA-FISH experiments

Rory Kruithoff, Mauri Dobbs Spendlove, Steven J. Sheppard, Max Schweiger, Pedro Pessoa, Mohammad Ali Abbasi, Steve Pressé, Benjamin B. Bartelle, Douglas P. Shepherd

This paper introduces a GPU-accelerated framework for processing 3D multiplexed RNA-FISH data, quantifies information loss from axial sampling, and improves post-mortem sample quality.

REPOP: bacterial population quantification from platecounts

Pedro Pessoa, Carol Lu, Stanimir Asenov Tashev, Rory Kruithoff, Douglas P. Shepherd, Steve Pressé

REPOP reconstructs bacterial populations from platecounts by accounting for dilution and plating uncertainties, revealing hidden multimodality that standard methods obscure.
