Abstract

Objective; Breast milk has an important function in the formation of the intestinal flora. Cesarean section bypasses the vertical transition of vaginal flora to the baby also usually causes the late start of lactation. The difference is in birth style and lactation period may affect the microbiota of breast milk. In this study, it was aimed to investigate how Lactobacillus species found in breast milk differ by the birth style and stages of milk.
Methods; Milk samples were taken from 72 mothers who had a vaginal birth (n:36) and cesarean (n:36) were divided into three groups as colostrum (n:12), early milk (n:12), and mature milk (n:12). Lactobacillus species were investigated from milk samples by real-time PCR.
Results: While Lactobacillus was detected in 70 (97.2%) of the samples, it was not detected in 2 (2.8%) of the samples taken from women with cesarean delivery. L. acidophilus and L. rhamnosus were detected simultaneously in all transitional milk samples of women who had a vaginal birth, and 82 Lactobacillus species were detected. The species identified were 33(39.3%) L. rhamnosus, 25(29.8%) Lactobacillus spp., and 24(28.6%) L. acidophilus. The rate of detection of L. acidophilus in milk samples taken from women who gave birth was found to be significantly higher than that found in milk samples taken from women who gave birth by cesarean section (p <0.05).
Conlusion: Breast milk is not only a nutritional source but an important source of probiotics. Lactobacilli were found to be concentrated in breast milk. Also, Lactobacillus species detected in breast milk may differ according to the mode of delivery.
