Fig. 9From: Vitamin D and allergic airway disease shape the murine lung microbiome in a sex-specific mannerNumber of operational taxonomic units in lungs inversely correlated with serum 25(OH)D. Female BALB/c mice (dams) were fed vitamin D-containing (+) or vitamin D-null (−) diets from 3 weeks of age and used to produce offspring. A subgroup of the vitamin D-deficient male and female offspring was fed a vitamin D-supplemented diet for 4 weeks from 8 weeks of age (−/+). A significant inverse correlation was observed between the number of operational taxonomic units (OTUs) in the lungs and circulating 25(OH)D levels (for n = 18 mice for whom both measures were obtained)Back to article page
