Two recent meta-analyses concluded that Lactobacillus therapy is safe and effective as a treatment for acute infectious diarrhoea (including rota-virus diarrhoea) in children.
Clearly evaluated strains include L.rhamnosous, L.reuteri and L.acidophilus.
A Cochrane database review concluded that certain defined probiotic strains reduced the mean duration of diarrhoea by 30,5 hours.
