Primary Outcome Measures:
  • incidence of mastitis [ Time Frame: up to 16 weeks ]
    mastitis was defined as at least two out of the three breast symptoms (pain, redness, lump) and at least one of fever or flu-like symptoms (shivering, hot sweats or aches)

Secondary Outcome Measures:
  • evaluation of breast pain [ Time Frame: at times 0, 4, 8, 12 and 16 weeks ]
    For pain evaluation a score from 1 (no pain) to 10 (extremely pain)

Other Outcome Measures:
  • microbiota breast milk [ Time Frame: at time 0 and 16 weeks ]
    DNA will be extracted from breast milk samples. Staphylococcus genus, Streptococcus and Lactobacillus will be evaluated by qPCR with specific probes designed to quantify these bacterial genus.

  • fecal microbiota of infants [ Time Frame: at 0 and 16 weeks ]
    DNA will be extracted from infant´s feces samples. Lactobacillus, bifidobacterium, clostridium, bacteroides will be evaluated by qPCR with specific probes designed to quantify these bacterial genus.

  • growth of infants [ Time Frame: at 0 and 16 weeeks ]
    Weight, length and head circumference will be measured in infants at the beginning and at 16 weeks

Arms Assigned Interventions
Placebo Comparator: Maltodextrin
1 capsule/day for 16 weeks
Dietary Supplement: Maltodextrin
Intervention with a daily capsule containing maltodextrin as placebo
Experimental: Lactobacillus fermentum CECT5716
L.fermentum 3,00E+09cfu/day. 1 capsule/day for 16 weeks
Dietary Supplement: Lactobacillus fermentum CECT5716
Intervention with a probiotic strain in form of a daily capsule containing 3x109cfu/capsule.

Detailed Description:
Previous studies have demonstrated that L. fermentum CECT5716, a probiotic strain previously isolated from breast milk, can be used as an effective treatment of mastitis and painful breastfeeding by reducing pathogen counts in breast milk. This is a randomized double blinded controlled study to evaluate the effect of L.fermentum CECT5716 on mastitis incidence and Staphylococcus load in breast milk. Women will be recruited 1-6 days after child birth and distributed into two groups: Probiotic group receiving 1 capsule/day containing L.fermentum 3x109cfu; Control group receiving 1 placebo capsule/day containing maltodextrin. The intervention period is 16 weeks.

Ages Eligible for Study:   18 Years to 40 Years   (Adult)

Childbirth took place 1-7 days prior to recruitment.. With firm intention to breast-feed their children for at least 16 weeks..

Exclusion Criteria:

  • - Mammary pathologies that hinder or preclude breastfeeding.
