Only Lactobacillus GG showed a consistent effect .
There is evidence of a clinical ly significant benefit of probiotics in the treatment of  acute infectious diarrhea in infants and children , particularly in rotaviral gastroenteritis .
Lactobacillus GG showed the most consistent effect , although other probiotic strains may also be effective .
Clinical and statistical heterogeneity of the prophylactic interventions preclude drawing firm conclusions about the efficacy of probiotics in preventing acute gastroenteritis
BACKGROUND This review was design ed to assess the evidence from r and omized controlled trials on effects of probiotics in the treatment and prevention of acute infectious diarrhea in infants and children .
Management of acute diarrhoea with low osmolarity oral rehydration solutions and Lactobacillusstrain GG
Two hypotonic oral rehydration solutions with osmolarities of 224 mosmol/l ( Na+ 60 mmol/l , glucose 84 mmol/l ) and 204 mosmol/l ( Na+ 60 mmol/l , glucose 64 mmol/l ) , respectively , and oral treatment withLactobacillus GG were evaluated in a double blind trial in children aged 6–36 months hospitalised for acute diarrhoea . Early administration ofLactobacillus GG at the start of oral rehydration result ed in the shortest duration of diarrhoea , best weight gain , and fastest correction of acidosis . A reduced osmolarity oral rehydration solution  ( 224 mosmol/l ) combined with early administration of Lactobacillus GG is an effective treatment for acute diarrhoea  in young children ; further reduction of osmolarity may not be beneficial
