Clearly the acid-alkaline debate is more complicated than the health gurus make it out to be.

There are many alka-trophs or bacteria that thrive in alkaline environments. Some bacteria hang out around the gallbladder (eg Salmonella typhi) because they like the alkaline environment.

Alkaline/acid isn't the only variable to getting an infection. If it was, we humans would have been dead a long time ago.

I think it almost more important to think of the body's mineral reserves than the pH. pH is one way of measuring mineral reserves but it is not without flaws. Just go over to Ask Andreas. He is not into testing urine and saliva pH.

Overall nutrition and immunity are the key factors. Oxygen is also vital and oxygen revolves around the pH. Hemoglobin uptakes oxygen much more efficiently in an alkaline environment. There are bacteria that can live in this environment but mostly minimally tolerate it.
