Matrix of pairwise interpopulation FST values for Escherichia coli from humans, livestock, and nonhuman primates in Kibale National Park, western Uganda, and 3 nearby forest fragments

| Livestock | 0.030 (0.007)1 | ||
| Nonhuman primates in forest fragments | 0.102 (0.024)2 | 0.090 (0.021)2 | |

*FST values (which can vary between 0 and 1) represent short-term genetic distances between bacterial populations and were calculated from Rep-PCR data by using optimal analytical parameters (30). Standard errors were estimated from bootstrap analyses with 1,000 replicates. Each of the 6 FST values shown is statistically significantly different from the null expectation of no genetic difference between populations, based on the bootstrap analysis (all p<0.01). Different superscript numbers indicate significantly different FST values (exact probabilities <0.05).
