Quantifying temporal changes in O. formigenes colonization induced by changes in diet. Detection of O. formigenes in fecal samples obtained from a subject on a normal diet who was then placed on a diet low in oxalate-containing foods followed by a diet high in oxalate-containing foods. Amplifications were carried out with 1 μl of sample DNA alone (lanes 6) and in the presence of 42 (lanes 1), 83 (lanes 2), 415 (lanes 3), 830 (lanes 4), or 8,300 (lanes 5) copies of the competitive template.
