TABLE 1.
Wk of gestation | Avg. C-R length (cm) | No. of offspring | No. stillborn (%) | Spleen (avg. log10/g) | Liver (avg. log10/g) | Lung (avg. log10/g) | Stomach contents (no. [%]) |
---|---|---|---|---|---|---|---|
Wk 5 | 40.8 | 24 | 0/24 (0) | 0 | 0 | 0 | 0/24 (0) |
Wk 6 | 46.8 | 21 | 0/21 (0) | 0.02 | 0.14 | 0.13 | 0/21 (0) |
Wk 7 | 59.9 | 17 | 3/17 (17.6) | 0.93 | 1.13 | 0.93 | 6/17 (35.3) |
Wk 8 | 50.8 | 20 | 6/20 (30) | 0.57 | 0.86 | 0.40 | 2/20 (10) |
C-R length was measured from the base of the skull to the point of the hip and is reported as the average (avg.) length in centimeters (cm). Fetal viability is reported as the number (no.) and percentage born stillborn. Fetal spleen, liver, lung, and stomach contents were cultured on Farrell’s medium and results are reported as the avg. log10/g. Maternal infection variably resulted in vertical transmission to the fetus. Results of culture of stomach contents are reported as number and percentage with growth.
