Brief Summary:

A therapeutic as well as preventive role of probiotics has been suggested from results of different studies using different probiotics that have been tested, usually lactic acid producing bacteria such as lactobacillus, bifidobacterium and streptococcus species. The supplementation of probiotics to infants may also have a prophylactic effect against acute diarrhoeal diseases.

In the present proposal, we plan to examine if daily intake of a probiotic beverage, which includes 15 billion probiotic Lactobacilli, has a beneficial role in protecting children from infectious diarrhea in Kolkata.


Primary objectives:

  1. To assess the impact of probiotics in the prevention of acute diarrhoeal diseases in children
  2. To assess the impact of probiotics on nutrition and growth of the children

Secondary Objectives:

  1. Reduction in duration, frequency of diarrhoea
  2. Identification of pathogens causing diarrhoea
  3. Examination of faecal microflora


It will be a double blind randomized controlled field trial involving 4000 children aged between 1 and 5 years in an urban slum of Kolkata, India. The 4000 children will be identified through demographic survey. The study will be double blinded where the study arm will receive Probiotic drink, which includes 15 billion probiotic Lactobacilli, one bottle (65ml) daily (under supervision of a Health Worker) for 12 weeks and the control arm will receive a similar drink without the lactobacilli (Nutrient drink) daily for 12 weeks. Randomization will be done in a ratio of 1:1, i.e., the study arm and control arm will include 2000 children each. All the children under the study will be visited daily by a health worker who will supervise intake of Probiotic drink or Nutrient drink by the children. All the children will be followed up daily for 24weeks for identification of acute diarrhoea cases.
