Table 3. Estimated numbers (posterior means) of different patterns A-E of consecutive samples and the estimated acquisition and clearance rates (mean, 95% CI in parenthesis).

event	expected number
A: STA, strX → STA, strX	250
B: STA, strX → STA, strY	24
C: STA → STB	45
D: STA, strX → ∅	100
E: ∅ → STA, strX	17
rate parameter	post. estimate	threshold-based estimate
acquisition rate racq	0.16(0.15, 0.16)	0.15
clearance rate rclear	0.24(0.24, 0.24)	0.23

Above, ST denotes sequence type as before, str denotes the strain and symbol ∅ denotes a negative sample i.e. no bacteria detected.
