|---|---|---|---|---|
| Sheep | Human | Guinea pig | ||
| HU1958 | pap | + | + | − |
| HU1886 | pil | − | − | + |
| HU1903 | uca | − | − | − |
| P678-54 | None | − | − | − |
a
Strains designated HU are recombinant plasmid containing derivatives of the laboratory E. coli strain P678-54. Our previous studies have shown that strain P678-54 does not contain its own genes for pap, pil, or uca (G) pili.
