Mean viral load in fetal thymus, endometrium and fetal serum by fetal preservation category.

<p>Mean viral load (log₁₀ copies/µL of serum or mg of tissue) in fetal thymus, endometrium and fetal serum is presented for different fetal preservation categories from inoculated gilts. Superscript letters indicate significant differences in mean viral load for each preservation category within particular sample type obtained by the linear-mixed models. Values indicate total number of samples tested within each category and sample type. Error bars represent standard deviation. Fetal thymus: a:b, a:c, a:d, c:d, a:d <i>P</i><0.001; b:c <i>P</i> = 0.0046. Endometrium: a:b, a:c, b:c <i>P</i><0.001. Fetal serum: a:b <i>P</i><0.001.
