Antimicrobial agents are some of the most widely, and often injudiciously, used therapeutic drugs worldwide. Important considerations when prescribing antimicrobial therapy include obtaining an accurate diagnosis of infection; understanding the difference between empiric and definitive therapy; identifying opportunities to switch to narrow-spectrum, cost-effective oral agents for the shortest d...

background and aim: bacterial elimination from root canal system is one of the aims in endodontic treatments, so the addition of antibiotics to sealers can increase their antimicrobial efficacy, as in this study we are determining the in-vitro antimicrobial effect of ah26 and ah plus sealers mixed with amoxicillin, triple antibiotic pastes and nanosilver on enterococcus faecalis. materials and ...

background: anti-microbial agents have been used as a chemotherapeutic agent to improve oral health. this in vitro study was carried out to determine antimicrobial efficacy of different toothpastes and mouthrinses against the oral pathogens.     methods: a total of five toothpastes and five mouthrinses were tested for their antimicrobial activity against three oral pathogens namely, streptococc...

Antimicrobial photodynamic therapy (aPDT) was demonstrated to be effective against various species of Gram-positive bacteria. However, the complex structure a Gram-negative bacteria envelope limits application aPDT. Thus, goal this study improve efficiency antimicrobial with Fotoditazin uropathogenic The non-ionic detergent Triton X-100 and emulsifier Tween 80 were tested. effect extracellular ...

introduction: although bacteria producing biofilm are more resistance to antimicrobial agents, biofilm formation can stimulated by sub-minimal inhibitory concentrations (sub-mics) of some antimicrobial agents. therefore, we designed present study to investigate the  in vitro efficacy of several antibiotics (including ceftazidime, piperacillin, ticarcillin, carbenicillin, aztreonam, meropenem, g...

There has been great interest in intervention strategies based on plant essential oils to control pathogens such as Escherichia coli O157:H7 and Listeria monocytogenes (Lm). However, the poor solubility of essential oils in water makes it difficult to disperse evenly in food matrices, impacting food quality and antimicrobial efficacy. In the present study, eugenol was dispersed in nanocapsules ...

This investigation compared the effects of a fluoride dentifrice and toothpastes formulated with antimicrobial ingredients (stannous fluoride and triclosan/copolymer) on oral micro-organisms, including those found in samples taken from the human oral cavity. Microbiological techniques determined the minimum inhibitory concentrations (MICs) of each dentifrice necessary to inhibit the growth of b...

Concerted efforts by healthcare professionals and heightened public awareness has reduced the incidence of hospital-acquired infections in recent years. For example, the number of reports of meticillinresistant Staphylococcus aureus (MRSA) bacteraemia in England declined by 52% between January and March 2009, and January and March 2011. Similarly, the number of Clostridium difficile infections ...
