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
