FIG 5.

(A) Quantification of total bacteria, total S. suis, and S. suis serotypes 2 and 1/2 by qPCR in SCB1, combining different rooms for different age groups. Shown are analyses of rooms that housed four steps, corresponding to different age groups (Table 1). Each symbol on the graph represents one air sample. The dashed line represents the detection threshold. The horizontal lines represent medians. (B) Ratios of S. suis serotype 2 to total S. suis were calculated to compare the change in airborne concentrations between different age groups in the same SCB. The top of the box plot represents the 75th quartile and the bottom the 25th quartile, the median is the horizontal line, and the lower whisker represents the minimum with the upper representing the maximum.
