Biochemical properties of Streptococcus sobrinus reisolates from the gastrointestinal tract of a gnotobiotic rat.

Streptococcus sobrinus strain 6715-13-201 was inoculated into the oral cavity of a gnotobiotic rat and then reisolated from different portions of the gastrointestinal tract. Fourteen isolates, selected on the basis of their colonial morphology, were then screened for their ability to adhere to saliva-coated hydroxyapatite (SHA) in vitro, and their ability to produce extracellular polysaccharide from sucrose, and...
