Suggestions as to quantitative measurements of plasmid loss.
Suggestions are made for the estimation of plasmid loss rates in bacterial populations that multiply by binary fission. The plasmid loss rate is defined as the probability of a division of a plasmid-carrying individual giving birth to one plasmid-free and one plasmid-carrying daughter cell. The unit of time is consequently the interdivision time for plasmid-carrying individuals. The cautions that have to be taken when the population is cultivated in serial transfer (the usual stability experiment) are discussed.
