TABLE 4.
Population differentiation estimates (PhiPT) to determine the extent to which colicin Ia nucleotide sequence variation depended on the host group from which the strains were isolated or whether the strains also encoded microcin V
| Comparisona | PhiPT | Probabilityb |
|---|---|---|
| Ia animal vs Ia human | 0.101 | 0.040 |
| Ia animal vs IaV animal | 0.480 | 0.001 |
| Ia human vs IaV animal | 0.386 | 0.002 |
| Ia animal vs IaV human | 0.292 | 0.001 |
| Ia human vs IaV human | 0.127 | 0.014 |
| IaV animal vs IaV human | 0.129 | 0.081 |
a
Ia, colicin Ia; V, microcin V; IaV, colicin Ia plus microcin V.
b
The probability that a greater PhiPT value could have arisen by chance.
