Table 1 Comparison of the major genomic features of L. ruminis ATCC 27782, L. ruminis ATCC 25644, and L. salivarius UCC118. Figures for ATCC 25644 are estimates based on the draft assembly and automated annotation, and pseudogenes were not predicted due to low quality regions and sequence gaps. Numbers in parentheses for L. salivarius UCC118 refer to contributions from the megaplasmid pMP118.
