Similarities and differences between the two major bovine lineages and related human lineages
| Bovine lineage | Human lineage | Similarities | Differences |
|---|---|---|---|
| III-1 |
III-1 |
Same infB allele (A)
No inserted sequences in AW-10, hylb or scpb-lmb sites
Sequence types (STs) the same or differ by <1 allele by multilocus sequence typing (MLST) |
Many bovine III-1 strains lack scpb-lmb |
| H allele | III-3 | GBSi1 inserted in AW-10 site No inserted sequence in hylb STs differ by only two alleles by MLST III-3 specific sequence tags in genome | Different infB allele (H vs C) BSi1 not found in scpb-lmb Additional inserted sequences or none in AW-10 site with GBSi1 Some bovine H allele strains lack scp-lmb |
