Group

This group investigates the mechanisms of resistance of bacteria to antibiotics, and new ways to circumvent them. Group found that the mouth carries a very high


proportion of bacteria resistant to several antibiotics. With concerns >> << was their opinion that this high level of antimicrobial resistant organisms


present in humans (including children) who


-not recently (within 3 months) was obtained drugs . In addition, resistant species can persist in the mouth for a long period >> << time (more than 18 months) in the absence of antimicrobial products.


As well as identifying the genes responsible for


antimicrobial resistance in bacteria of the mouth, they have been identified and characterized a novel


antimicrobial resistance genes. In addition, the group


showed that the genes that encode resistance to antimicrobial agents may


transfer between organisms (even those that are distantly related) and >> << in vitro and in vivo. The team also conducted extensive research


in exile in bacteria of the oral cavity between the


resistance and resistance to mercury. Just as


to show that healthy individuals harbor high oral >> << bacteria resistant to mercury, antimicrobial agents, they


characterize genes that encode mercury resistance and is


showed that dental restorations mixture can force >> << colonization by bacteria (eg, Streptococcus oral) that can be >> << systemic relevance in the immune host. Group


first separate profile of resistance to antimicrobial drugs in the endodontic microflora >> << and determine which resistance genes can be transferred between


bacterial isolates from root canals. Group


In addition, significant progress in the development of Novi


antimicrobial technology. One particular emphasis was placed on photodynamic therapy >> << funded by large research council (SIBBN, EPSRC, MRC),


Charles Wilson Foundation and Industry (Ondine Pharma and


Dentofex). Group developed a new photosensitizers that can selectively affect


to kill certain microorganisms, including


meticillin resistant Staphylococcus aureus


(MRSA) and important periodontopathogen gingivalis Porphyromonas. received a further development of relations with industry (Ondine Biopharma) for treatment


system that is used in the clinic, was launched in


Pacific Dental Conference in Vancouver, Canada in 2006 and now


used by 15% of Canadian dentists. Ondine Biopharma recently received


sign of CE, which will allow them to sell Periowave in Europe. Sustainable quality of this theme is reflected burning


EPSRC funding and Ondine Pharma, expanding the use of


light-activated antimicrobial coating new photosensitizers


and methods for selective effects on bacteria. Another important topic is the study of natural products


with antibacterial, anti-inflammatory or anti-adhesive


compounds for the prevention and / or treatment of caries and periodontitis


. International consortium led by UCL-EDI group


recently was awarded


(2. 2 million euros) to determine the characteristics and evaluation of compounds


present in foods and beverages that may be useful for prevention


and / or treatment of oral diseases . They plan to include such compounds


to means of oral hygiene and the development of functional food
