TABLE 2.
Number of PFGE patterns from different sources indistinguishable from patterns of human isolatesa
| Source | Total no. of patterns | Overall % patterns indistinguishable | No. of common patterns indistinguishableb |
|---|---|---|---|
| Beef cattle | 129 | 56.6 | 23/23 |
| Dairy cattle | 157 | 65.0 | 34/34 |
| Pigs | 283 | 9.5 | 5/14 |
| Poultry animals and retail meat | 196 | 49.5 | 19/19 |
a
Patterns indistinguishable are indistinguishable from those of human isolates in the CDC PulseNet database.
b
Common patterns encompass three or more isolates from a particular source; this total is the denominator in each cell.
