description: Zip File "Data_sets_Phage_titers"

Raw phage and bacteria countings (i.e. plaque-forming units [PFU] for phages, colony-forming units [CFU] for bacteria) and plaque morphology data for data analysis and visualisation in the code found in https://github.com/OReyesMatte/Reuter_2025/tree/main/Data_analysis.

 

The folder contains eight csv files of a total of seven experiments, which are described in detail below. Information about the data columns of each file is mentioned below, as well as in the code file. 

 

In the following, the individual experiment files are described in detail:

 

Experiment 1:
