Spa types found over time in rooms that were positive at more than one sampling moment. Spa types observed at different moments or in different rooms are colored, spa types observed at only one moment in one room are grey. Darker grey was used to indicate that two spa types were identified at one moment, but in the same room. Node sizes are relative to the number of MSSA strains found.
