Group B streptococcus colonization of breast milk of group B streptococcus positive mothers.

BACKGROUND: Breast milk is occasionally considered as a potential source of neonatal infection. Only a few cases of transmission of Streptococcus agalactiae (GBS) through breast milk have been published. The incidence of GBS in breast milk varies among studies. The incidence of GBS in breast milk in mothers with positive prenatal vaginal swabs for GBS is not known. OBJECTIVE: The objective of this study was to compare the incidence of GBS in the breast milk of women colonized with GBS before delivery (GBS vaginal swabs positive) and women non-colonized with GBS (GBS negative) during the first week after term delivery. METHODS: Breast milk from our sample of women was checked for the presence of GBS. A sample of 5 ml of breast milk was collected from each woman between days 3 and 7 after term delivery. Statistical analysis was carried out to test the relationship between bacterial content and GBS status of the women. RESULTS: We identified only 2 of 243 (0.82%) GBS positive breast milk cultures during the study, both in the GBS negative group. There was found to be no GBS positive breast milk in women with positive prenatal vaginal swabs for GBS. CONCLUSION: The incidence of GBS positive cultures in breast milk in the study was low. When comparing the incidence of GBS positive breast milk cultures between women colonized with GBS before delivery and women non-colonized with GBS, we identified only 2 GBS positive breast milk cultures, both in GBS non-colonized women.

Impact of breast-feeding promotion on infant feeding in the Czech Republic.

OBJECTIVES: To assess infant feeding practices, identify factors that influence the duration of exclusive breast-feeding, and evaluate the impact of the National Breastfeeding Promotion Programme in the Czech Republic. HYPOTHESIS: We predicted the positive effect of the program in terms of increased prevalence of breast-feeding at discharge from the hospital and 6 months later. DESIGN: Multicenter cross-sectional survey. Mothers were randomly selected and interviewed in maternity hospitals in 1998 and were reinterviewed 6 months later. SETTINGS: Nine maternity hospitals in 6 cities across the country and households. PARTICIPANTS: 1104 mothers who gave birth within the 38th to the 42nd week of pregnancy to a healthy child with a minimum birthweight 2500 g; 1019 mothers were reinterviewed 6 months later. INTERVENTION: The National Breastfeeding Promotion Programme implemented since 1991. VARIABLES MEASURED: Breast-feeding rates at discharge from the hospital and 6 months later, participation in prenatal classes, strategies related to breast-feeding promotion in the hospital, and support following discharge. ANALYSIS: Epi Info 6, SPSS (analysis of variance, F test), chi2. RESULTS: On leaving the hospital, 93.5% of newborns were exclusively breast-fed. Six months later, 23.1% of infants were breast-fed exclusively and 29.9% of infants were breast-fed while receiving complementary food. Participation in prenatal classes, first suckling within 2 hours of birth, breast-feeding on demand in the hospital, exclusive breast-feeding on leaving the hospital, and the duration of breast-feeding recommended by a pediatrician were positively related to the duration of exclusive breast-feeding (P <.001). CONCLUSIONS AND IMPLICATIONS: Compared with national data from the last 2 decades, the data from this study proved the increasing rates of breast-feeding at discharge from the hospital and 6 months later. The findings indicate the effectiveness of the National Breastfeeding Promotion Programme. However, further implementation of breast-feeding promotion strategies in health facilities coordinated by the Ministry of Health is needed.
