Brief Summary
The goal of this clinical trial is to study if a oral maternal fecal transplant given to a premature infant born by cesarean section (CS) is safe. The investigators will also compare the gut microbiome of the infants to those born by CS and not received the transplant and to premature infants born vaginally.

Outcome Measures
Primary Outcomes (1)
Safety; Incidence of Treatment- Adverse Events eg. infections and increased need for respiratory support
The primary outcome of the study is safety of the transplantation process. The patients are followed with measurements of markers of inflammation (C-reactive protein (CRP) and blood leucocytes) on the day of transplant and three consecutive days. Clinical symptoms of infection are monitored (such as apnea, tachycardia, fever) as well as symptoms of the gastrointestinal tract (vomiting, diarrhea, feeding intolerance). Any suspected adverse events (such as infections, increased need for respiratory support) are recorded.
3 months
Secondary Outcomes (1)
The secondary outcome is the difference in heterogeneity of the intestinal microbiome between infants receiving transplant and the control subjects at 3 and 6 months of age.
6 months
Study Arms (3)
Intervention
EXPERIMENTAL10 infants born by CS to screening negative mothers receive an oral maternal fecal transplant (from their own mother) containing 0.35mg/kg of maternal fecal content at the age of 2-7 days of age.
Control
NO INTERVENTION12 infants born by CS (8 to screening negative mothers and 4 to screening positive mothers in case of Blastocystis hominis or Dientamoeba fragilis).
Comparison
NO INTERVENTIONInfants born vaginally to mothers with screening negative or mild pathogene findings (Blastocystis hominis or Dientamoeba fragilis)
Interventions
0.1-0.3 ml liquid containing 3.5 mg/ml of maternal fecal content, (0.35mg/kg)
