Cell concentrations associated with genomics sampling to characterize bacterial responses to parasite-host metabolites from bottle incubation experiments in June of 2024

Bottle-based incubation experiments were conducted with coastal seawater that was filtered to include only the bacterial fraction. Fresh filtrate from Scrippsiella acuminata cultures infected by Amoebophrya sp. were collected and added into coastal seawater to expose heterotrophic bacterial communities to parasite-host metabolites and explore changes in bacterial community composition and gene expression over time. Data reported here are cell concentrations of bulk heterotrophic bacteria measured via flow cytometry that accompanied samples collected for DNA metabarcoding and metatranscriptomics from the incubation bottles over time.
