| EF0501 | 18.4 | 5.8 | 0 |
| EF0518 | 15.8 | 5.8 | 20 |
| EF0573 | 13.1 | 0 | 0 |

| EF1896 | 31.6 | 21.2 | 10 |
| EF2144 | 15.8 | 0 | 10 |
| EF2170 | 26.3 | 1.9 | 0 |

| PAIEF0050 | 13.1 | 0 | 0 |
a
Distribution of individual genes was determined by PCR and analyzed by a Fisher exact test. Values in boldface indicate significant results between dairy food and clinical isolates with a P value of <0.05.
b
Genes cylA and EF2168 were not probed as they are putatively cotranscribed with cylB and EF2170, respectively.
