Motility in Urinary and Non-Urinary Bacterial Strains

A recent study from the Putonti lab concluded that there are two genetically distinct lineages of the bacterium Streptococcus anginosus: group 1, found throughout the body; and group 2, found in the urogenital tract. A 1995 study asserted that urinary strains of S. anginosus exhibited motility, but this was observed before current taxonomic classifications were established. Here I test for motility in both groups of S. anginosus. I expect to find evidence of motility in S. anginosus group 2, but not in group 1. This will add to the classification criteria of group 2 as S. anginosus subsp. urinae.
