Bures et al. (1986) isolated E. coli from the feces of 77 colorectal carcinoma patients, where 32 patients (41.6%) had barteriocins-producing E. coli. In the feces of 160 healthy people, 102 people (63.8%) had barteriocins-producing E. coli , which also showed that colicins from bacteria in the intestine may be one of the factors in reducing Streptococcus mutans and Lactobacillus acidophilus are the organisms which are responsible for initiation and progression of it. Natural phytochemicals can be an effective alternative to antibiotics and represent a promising approach in the prevention of dental caries and other oral infection. It has the ability to kill all oral streptococci However, intracellular ATP pools were largely unaffected in E. coli and L. innocua cultures upon exposure to 50 mmol l(-1) vanillin, while ATP production was stimulated in Lact. plantarum cultures. In contrast to the more potent activity of carvacrol, a well studied phenolic flavour compound, the extent of membrane damage caused by vanillin is Enterococci has two main species - Enterococcus faecalis and Enterococcus faecium; the antibiotics listed are active against E.faecalis, but have limited activity for E.faecium Cloxacillin and clindamycin typically have less than 40% activity for S.epidermidis, thus usage depends on local susceptibility data A multi-year study of the role of E. coli gut bacteria in Crohn’s disease finds that intestinal inflammation liberates chemicals that nourish the bacteria’s growth and promotes their ability to cause inflammation. The results identify new avenues for treatments that selectively disrupt the compounds that feed E. coli. dUctGX.
