The subgingival microbial flora during pregnancy

The subgingival microbial flora during pregnancy.

The subgingival bacterial flora from 2 gingival sites was cultured and characterized monthly in twenty periodontitis-free women during pregnancy and again post-partum. Monthly plaque samples were also cultured in eleven age and disease matched non-pregnant women. Plaque was processed anaerobically on selective and nonselective media and the predominant colony types were characterized. A portion...

Microbial flora of the lower genital tract during pregnancy: relationship to morbidity.

Nineteen genera and groups of micro-organisms were isolated from the lower genital tract of 280 women at their first antenatal visit. Chlamydia, viruses, and T-strain mycoplasmas were not sought, and only routine methods of anaerobic culture were used. Growth was recorded as scanty, moderate or heavy. The population studied was grouped according to age, parity, gestational stage at booking, pre...

Microbial complexes in subgingival plaque.

It has been recognized for some time that bacterial species exist in complexes in subgingival plaque. The purpose of the present investigation was to attempt to define such communities using data from large numbers of plaque samples and different clustering and ordination techniques. Subgingival plaque samples were taken from the mesial aspect of each tooth in 185 subjects (mean age 51 +/- 16 y...

Smoking, pregnancy and the subgingival microbiome

The periodontal microbiome is known to be altered during pregnancy as well as by smoking. However, despite the fact that 2.1 million women in the United States smoke during their pregnancy, the potentially synergistic effects of smoking and pregnancy on the subgingival microbiome have never been studied. Subgingival plaque was collected from 44 systemically and periodontally healthy non-pregnan...
