Can probiotics prevent bacterial infections and sepsis?

Probiotics. The use of probiotics continues to increase along with the publication of studies to look at the issue of whether they help or not. Right now it appears to be a neutral issue: that is, the use of probiotics has not be shown to be harmful, may be helpful, and the worse thing is that it increases costs. Note that using active culture yogurts may be just as beneficial.
Unclear. There may be benefit by improving the health of your gut which is the largest immune organ. Indirectly this may help with infections, but there isn't enough data to be sure.
