| Species and strain(s) | Sourceb | Gene location | Transferability test result | No. of differencesa |
|---|---|---|---|---|
| Butyrivibrio fibrisolvens | ||||

| JK51 and JK214 | Sheep rumen, UNE (1996) | Chromosome | NDc | 0 |
| Selenomonas ruminantium | ||||
| FB322 | Bovine rumen, RRI (1989) | Chromosome | Nod | 1 |
| FB32 | Bovine rumen, RRI (1989) | Plasmid | Nod | 0 |
| FB34 | Bovine rumen, RRI (1989) | Plasmid | Nod | 0 |
| Mitsuokella multiacidus | ||||
| 46/5(2) | Sheep rumen, RRI (1987) | Chromosome | Nod | 0 |

a
Number of nucleotide differences from 1.230 tet(W) found over a 1.25-kb internal fragment. PCR-amplified template DNA was sequenced; hence, Taq polymerase errors cannot be ruled out as possibly contributing to nucleotide differences.
b
Data in parentheses indicate year of isolation of bacterial strain. RRI, Rowett Research Institute, Aberdeen, United Kingdom; UNE, University of New England, Armidale, Australia.
c
ND, not yet determined.
d
Transfer was tested using Selenomonas ruminantium HD4 as a potential recipient.
