The primary identification based upon percent sequence identity as described in the materials and methods is indicated. The number of samples in which each bacteria was identified is provided along with the average percent (avg %) among the positive samples, the standard deviation (st dev) and the range of percentages among the positive samples. No. of samples = the no. of samples in which the genus were identified Mean % = the average percentage of that genus in each of the samples SD = standard deviation of these percentages Maximum % = the maximum percentage of the genus in each sample * + Gram-positive; - Gram-negative

† Anaerobes are unable to propogate in laboratory media in the presence of oxygen; facultative anaerobes can grow both in the presence and absence of oxygen; aerobes can grow in the presence of oxygen
