Some factors can alter this balance of organisms in our gut. For example, antibiotics tend to kill off the "good bacteria" along with the bad they are targeting. A diarrhea illness can also reduce the amount of beneficial bacteria. In these cases, trying to increase the amount of helpful micro-organisms in our gut with probiotics makes sense. Doing so can decrease the risk of diarrhea from antibiotics as well as prevent or lessen the severity of an infectious diarrhea illness. Recent studies have shown that probiotics may also help ward off and decrease the duration of cold and flu-like symptoms.

Take note that not all probiotics are equal. There are different groups of probiotics, such as Lactobaccilus and Bifidobacterium, as well as many different species, such as Lactobaccilus acidophilus and Bifidobacterium bifidis, which are further subdivided into specfic strains. What may hold true for one strain may not be extended to all strains. As research continues, we will learn more about which strains may be most beneficial for certain illnesses.
