Note: Levels of vitamin D represent samples from 21 subjects. Four of the subjects presented amounts of TNF-α were below the detection level. In these subjects, TNF-α levels were recorded as zero. Due to the number of bacterial species evaluated, only those that presented differences with associated p values<0.05 were included in the table.
