Table 1.
Nicotine did not impact the percentage of maternal sites colonized by M. pulmonis.
| Site | MP only | Nic + MP | P value |
|---|---|---|---|
| Uterus | 5/5 (100%) | 7/7 (100%) | NA |
| Placenta | 53/61 (87%) | 74/79 (94%) | 0.28 |
| Amniotic fluid | 43/57 (75%) | 73/80 (91%) | 0.02 |
| Fetus | 22/28 (79%) | 36/36 (100%) | 0.01 |
| Spleen | 4/5 (80%) | 7/7 (100%) | 0.86 |
| Vagina | 3/5 (60%) | 7/7 (100%) | 0.29 |
Statistically significant differences (Chi Square with Yates correction factor) are shown in bold. All fetal units had placental and amniotic fluid cultures performed; however, fetal cultures were available only for a subset of the total fetal units. Mycoplasma pulmonis was never isolated from any control or Nic only rats.
