My Rebuttal

While these facts "off the top of your head" may be true, I would like to point out that the small intestines do not have many microorganisms (Guarner and Malagelada, 2003b; University of Glasgow, 2005). E. coli are mostly in the colon, and E. coli O157:H7, an enterohemorrhagic E. coli, is not part of the normal flora. So what you said is true, but it doesn't answer the question. Many normal flora outside of the region where they normally grow can be pathogenic, and as you already seem to know, they are also a problem in immunocompromised people. So technically, the presence of disease causing bacteria (causing disease where they are found) is not normal, it is pathogenic, and in healthy people normal flora can only cause disease when spead away from their typical location. It can be said that E. coli of the colon are disease causing in that they can cause a UTI, or urinary tract infection, when spread there, but they are not disease casing as they normally exist in the colon.

C. albicans does grow in the vagina, but is usually inhibited by acid produced by lactobacilli. Before puberty and after menopause, lactobacilli are rare, which can lead to overgrowth of C. albicans and resulting Candida vaginitis (Levinson 2006).

I won't give any lectures on city or state political theory, and I don't need any of these on medicine, bitch.
