Median relative abundance of phyla Firmicutes and Proteobacteria by quarter in week 1 sample. Line plots indicating shifts in the median relative abundance of selected taxa by quarter for hospital 1 and hospital 2 in week 1. Red lines indicate hospital 1 and blue lines indicate hospital 2. Quarters 1, 7, and 8 are excluded because fewer than three infants per hospital had samples during those quarters. (A) Median relative abundance of Firmicutes. In hospital 1, Firmicutes started high in 2010 and then fell in 2011. In hospital 2, Firmicutes started low in 2010 and then rose slightly in 2011. (B) Median relative abundance of Proteobacteria. At both sites, Proteobacteria followed a pattern opposite to that of Firmicutes. (C) Median relative abundance of Staphylococcaceae, the most commonly detected family of Firmicutes. Pattern in the relative abundance of Staphylococcaceae was similar to that of Firmicutes for most quarters. (D) Median relative abundance of Enterobacteriaceae, the most commonly detected family of Proteobacteria. Pattern in relative abundance of Enterobacteriaceae was similar to that of Proteobacteria for most quarters.
