Lactobacillus
Last reviewed 01/2018
Lactobacilli are gram positive bacilli which are commensal with human beings.
There is evidence, via a meta-analysis by Van Niel et al (1), that treatment with Lactobacillus (a probiotic) is effective for accelerating the recovery from infectious diarrhoea. The effect size was a reduction of diarrhoea of 0.7 days and reduction of 1.6 stools on day 2 of treatment. Note however in this meta-analysis:
- different types of lactobacilli may have different effect sizes - in this study the results of Lactobacillus GG, L reuteri, L bulgaricus and L acidophilus were combined
- a clear dose-response relationship was found
The results of this meta-analysis are encouraging but there is a need for more data before a universal recommendation on the use of lactobacilli can be made (2)
