TABLE 1.
Hybridization of E. coli 83972 with probes for adhesin genes associated with E. coli causing extraintestinal infections
| Adhesin gene | Pilus | Hybridization | HAa | Infection associated with adhesin |
|---|---|---|---|---|
| pil | Type 1 | +b | −/weak | UTI (43) |
| pap | P | +b | −/− | Pyelonephritis (38) |
| uca | G | + | −/− | UTI (6, 39) |
| foc | Type 1C | + | NT | UTI (37) |
| dra | DR | − | − | Cystitis (34) |
| sfa | S | − | − | Meningitis (36) |
a
Results are shown for bacteria passaged in broth and urine (broth/urine); HA was observed only after 10 passes. NT, not tested (this adhesin does not mediate HA).
b
DNA sequences homologous with pap and pil were present as single copies on the E. coli 83972 chromosome.
