TABLE 3.
Travel destinations of travelers who were negative for ESBL-producing strains before the trip and rate of fecal colonization with ESBL-producing E. coli strains upon returna
| Continent or region | No. of travelers | No. (%) of travelers positive for ESBL-producing isolates |
|---|---|---|
| Africa | 25 | 1 (4) |
| Asia (India excluded) | 31 | 10 (32) |
| Central America | 6 | 0 (0) |
| India | 8 | 7 (88) |
| Middle East | 14 | 4 (29) |
| North America | 2 | 0 (0) |
| South America | 1 | 0 (0) |
| Southern Europe | 16 | 2 (13) |

The rate of acquisition of ESBL-producing strains was highest for travelers visiting India (P < 0.001). Three participants visited more than one continent, and therefore, the sum of travelers in this table exceeds the actual number of 100.
