Fnrthermore, NCD has also demonstrated a promise for reducing bacterial infection, which is highly desired for orthopedic implant materials because invasive surgery is inevitably associated with infection. A preliminary study compared the number of Escherichia coli colonized on NCD, stainless steel and titanium, and showed that NCD has the highest bacterial resistance [119]. This possible anti-infection effect is highly desirable for orthopedic implants and, thus, should be further studied.

Blood in stool indicates the possibility of inflammatory mucosal disease of the colon. Enterohemorrhagic Escherichia coli (EHEC) is an important cause of bloody diarrhea in the United States.

The nitrate (NOp content in crops is one of the most important indicators of farm production quality. Nitrate content in food is strictly regulated because of its toxicity, especially in young children. The actual toxin is not the nitrate ion itself but rather the nitrite ion (NOp, which is formed when nitrate is reduced by intestinal bacteria, notably Escherichia coli. In adults, nitrate is absorbed high in the digestive tract before reduction can take place. In infants, whose stomachs are less acidic, E. coli can colonize higher up the digestive tract and therefore reduce the NOJ to NCp before it is absorbed.

Hydrogenase was named by Stephenson and Stickland in 1931, discovered in their experiments using anaerobic colon bacterium Escherichia Coli that evolved hydrogen [144-146]. Hydrogenase enzymes are metalloproteins that contain sulfur and nickel and/or iron [147]. To date over 80 hydrogenase enzymes have been identified. These enzymes reversibly catalyze hydrogen production/uptake reactions ... 

The colon contains about 400 different species of anaerobic and aerobic bacteria.15 The most common anaerobes in the colon are Bifidobacterium spp., Eubacterium spp., Peptostreptococcus spp., Fusobacterium spp., and Bacteroides spp. The most common aerobe in the colon is Escherichia coli.16,17 Colonic bacteria are involved in the synthesis of B complex vitamins and a majority of vitamin K.18...

The regulation of bacterial transcription is well illustrated by the lactose operon (lac operon) of the colon bacterium Escherichia coli in which the upstream region successively (from the 5 end of the sense strand) includes a promoter (P ) for the gene (I) coding for a repressor protein (the lac repressor), a CRP binding site , the promoter for the lac operon (P), and finally an operator site (O) that prefaces the Z, Y and A structural genes of the operon ... 

Pathogenic Escherichia coli strains, such as E. coli 0157, which produce a potent toxin, cause hemorrhagic infections in the colon resulting in bloody diarrhea or life-threatening complications such as kidney failure. E. coli 0157 outbreaks have been mainly related to beef consumption, however, sprouts, lettuce, and juice have also been found to cause outbreaks. 

The bacteria colonizing the small bowel (such as Escherichia coli and Bacteroides species) deconjugate and dehydroxylate bde salts, leading to conjugated bde salt deficiency, which causes fat malabsorption. Bacterial metabolism of vitamin B12 may also occur, leading to vitamin B,2 deficiency. The clinical symptoms of bacterial overgrowth are abdominal pain, diarrhea, and steatorrhea. ...
