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 (std dev) and the range of percentages among the positive samples. No. of samples = the no. of samples in which the species were identified Mean % = the average percentage of that species in each of the samples SD = standard deviation of these percentages Maximum % = the maximum percentage of the species in each sample * + Gram-positive; - Gram-negative

† Anaerobes are unable to propagate 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
