Does streptococcus gordonii 's sequenced strain CH1 glucosyltransferase determine persistent but not initial colonization of teeth of rats?
Initial S. gordonii colonization does not depend on Gtf-G synthesis; rather, Gtf-G production determines S. gordonii's ability to persist on the teeth of sucrose-fed rats. S. gordonii appears weakly cariogenic by comparison with S. mutans reference strains.
Roux-en-Y gastric bypass is a promising option for lifelong treatment of type 2 diabetes. It has the potential to improve or cure a selected spectrum of type 1 diabetes when performed early in the disease. Further animal model studies or randomized controlled trials are needed to support our conclusion.
