[Anaerobic bacteria of periodontal pockets in course of periodontitis and premature labor]. 
The aim of the study is was to evaluate anaerobic periodontal mikrobes in 120 postpartum mothers.  Group I consisted of mothers with a birth weight of less than 2,500g and gestational age < 37 weeks.  Group II included mothers with normal birth weight infants.  All women in both of groups were subjected to a full-mouth periodontal examination to determine a periodontal status.  The microbial investigation for anaerobic bacteria of deepest periodontal pockets was performed in 35 cases of periodontits.  A significantly higher incidence of preterm low birth weight cases in patiens with periodontitis was documented.  In addition higher variety of anaerobic bacteria of periodontal pockets in mothers with preterm low birth weight infants comparison to control group was observed.
