Objective: It was assess the antibiotic susceptibility of E. faecalis and S. aureus by using agar diffusion test. Material and Methods: For the experiment the following antibiotics were used: amoxicillin+clavulanic acid; amoxicillin; azithromycin, cephalexin, ciprofloxacin, erythromycin, clindamycin, penicillin G, oxacillin and vancomycin. Twenty Petri plates with 20 mL of BHIA inoculated with 0.1 mL of bacterial infusion were sowed by sterilized swabs. A hundred antibiotic discs were placed on… 



Methicillin-resistant Staphylococcus aureus clinical strain with reduced vancomycin susceptibility.

Therapy was resumed with the com -bination of arbekacin and ampicillin/sulbactam which has been shown to have synergic activity against MRSA.

It is postulated that a virulence factor of E. faecalis in failed endodontically treated teeth may be related to the ability to maintain the capability to invade dentinal tubules and adhere to collagen in the presence of human serum.

Antibiotic susceptibility of bacteria detected from the root canal exudate of persistent apical periodontitis.

Intracanal exudates in persistent endodontic cases were sampled for detecting bacteria using a preculture method, and the antibiotic susceptibility of the bacteria identified was examined, revealing that Enterococcus was highly resistant to antibiotics tested, especially to cephalosporin products.

Antimicrobial efficacy of ozonated water, gaseous ozone, sodium hypochlorite and chlorhexidine in infected human root canals.

The irrigation of infected human root canals with ozonated water, 2.5% NaOCl, 2% chlorhexidine and the application of gaseous ozone for 20 min was not sufficient to inactivate E. faecalis.

Staphylococcus aureus: a review of the literature.

This review documents the emergence of MRSA and recognition of the ensuing problems throughout the 1980s and early 1990s, with suggestions for nursing activities which could contribute towards improved control.

Associations between microbial species in dental root canal infections.

The results are consistent with the concept of a special and selective environment occurring in the root canal that is due, in part, to the cooperative as well as antagonistic nature of the relationships between bacteria in theroot canal.

Enterococcus faecalis– the root canal survivor and ‘star’ in post-treatment disease

The different factors that make E. faecalis a potential problem in medicine and dentistry are summarized, with special focus on the role of E. Faecalis in post-treatment endodontic disease.

Survival of Enterococcus faecalis in an Oligotrophic Microcosm: Changes in Morphology, Development of General Stress Resistance, and Analysis of Protein Synthesis

The combined data suggest that energy starvation induces a response similar to that triggered by oligotrophy, which seems to play a key role in the observed phenomena of long-term survival and development of general stress resistance of starved cultures of E. faecalis.
