This study is initiated to investigate the effect of infant formula with added specific synbiotics mixture on proportion of beneficial bacteria.

Inclusion Criteria:

• Healthy term infants (gestational age ≥ 37 1/7 and ≤ 41 6/7 weeks) aged 46 - 65 days (inclusive) at entry into the study
• Fully formula fed for at least one week (not applicable for the breastfeeding reference group since these infants must be exclusively breastfed before and throughout the study)
• Parents' or legal guardian's written informed consent

Exclusion Criteria:

• Exclusion criteria for run-in period (visit 1, screening) are:
• Being weaned before inclusion (introduction of any other foods other than formula or human milk)
• Moderate or severe acute malnutrition, defined as weight-for-age and sex below -2 z-scores of the median WHO growth standards
• Medical condition for which a special diet other than standard (non hydrolised) cow's milk-based infant formula is required
• Known congenital diseases or malformations which could interfere with the study (e.g. gastrointestinal malformations, congenital immunodeficiency), as per investigator's clinical judgement
• Use of systemic antibiotics or anti-mycotic drugs in the 4 weeks prior to entry into the study
• Received Inactivated Poliovirus Vaccine (IPV) or Rotavirus Vaccine (RV) prior to entry into the study
• Gastroenteritis or diarrhoea in the last two weeks prior to entry into the study
• Participation in any other studies involving investigational or marketed products concomitantly or within two weeks prior to entry into the study
• Investigator's uncertainty about the willingness or ability of the parents to comply with the protocol requirements
