Summary Introduction
To describe:
A scenario in which having long generation time would be advantageous to a pathogen.
Concept introduction:
Germination time also known as doubling time is the time taken by the bacteria to increase the population by a factor of "2" in number during a specified time period. The generation time is different for different organisms. For example the germination time is 20 minutes for E,coli and 30 minutes for S.aurieus.
