It's an interesting question that creates more questions. The human body is composed of around 10 trillion human cells that harbor 100 trillion micro-organisms. We are really super-organisms, 10% human and 90% micro-organism (bacteria, yeast, fungus, parasites, etc). If you consider the number of genes present in these cells, we are 1% human and 99% micro-organisms. The micro-organism side of the equation is very misunderstood and under-addressed.

The flora of the intestinal tract evolves over the course of our lifetimes based on vaginal vs. cesarean birth, environment, food choices, chemicals, medications, heavy metals, etc. The idea of fecal transfer makes sense, but the determination of what constitutes a proper donor for each person remains an unknown. Therein lays some possible risk. The idea of this has been around for a while, but the application of it hasn't always been successful.

Studies have shown that there are over 5600 species of bacteria in the intestinal tract. Many of these aren't able to be grown outside of the intestinal tract as yet, and most species are still unknown. With the probiotics that we have available to us, we know their general benefits and what we can expect based on the relatively small amount of research that we have to date. In essence, we know what we are getting with probiotics, but we don't know what we are getting with fecal transfer and whether or not it will benefit us.

Another question would be what does your body really need? Do you need species that are more necessary in the small intestine or large intestines? Lactobacillus species are dominant in the small intestine and that can probably be handled very well by taking probiotics. Bifidobacterium species are abundant in the large intestine and that can also be addressed through probiotics. An important species in the intestinal tract and primarily found in the large intestine is E. coli. Most of us are aware of this organism for the trouble that mutant strains can cause, but aren't familiar with its benefits. This is available in European and Russian probiotics and only recently in the US.

Transferring someone else's fecal material into your body may be benign, beneficial, or challenging. Consider that when you go to another country like Mexico, you can come down with a case of diarrhea (Montezuma's Revenge). That occurs because you're not used to the flora found in that country which is a part of their food and water supply. It's not necessarily harmful, it's just that it's not a part of the normal make-up of your body's flora, and so your body produces a reaction. Over time, you would get used to it as new species or strains colonized your intestinal tract.

I recommend probiotics because of their known benefits without risks. A good addition would be the Mutaflor. I would eliminate problematic fungal candida in anyone who had ever had an antibiotic first, and then go about restoring intestinal flora balance. Detoxification should be a part of every attempt to establish intestinal and body flora balance, as the health of our tissues has a major role to play in determining the effects of the bacteria, parasites, etc., in our bodies.

In the end, all of this comes back to questioning the validity of the use of antibiotics. Is it wise to engage in biological germ warfare against ourselves when we our an organism that relies heavily on the make-up of the flora in our bodies? We understand too little at this point in time about the 5600+ species that reside in our intestinal tract. The paradigm of Pasteur's germ theory is filled with errors, and something that he himself recanted before his death. In truth, it was a theory he borrowed from Antoine Beauchamp, which Beauchamp had previously discovered to be erroneous.

If antibiotics have a use, it is only in a dire emergency situation, such as can exist with burn victims.
