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… Expand


Antibiotic susceptibility of bacteria associated with endodontic abscesses.
Metronidazole had the greatest amount of bacterial resistance; however, if it is used in combination with penicillin V or amoxicillin, susceptibility of the combination withPenicillinV or am Toxicillin increased to 93% and 99%, respectively. Expand
Analysis of the antimicrobial susceptibility of anaerobic bacteria isolated from endodontic infections in Brazil during a period of nine years.
The antimicrobial resistance of anaerobes isolated from primary endodontic infections showed an increase throughout a period of time regarding a specific Brazilian population. Expand
Frequency, microbial interactions, and antimicrobial susceptibility of Fusobacterium nucleatum and Fusobacterium necrophorum isolated from primary endodontic infections.
This study assessed the prevalence and microbial interactions of Fusobacterium nucleatum and Fusobacterium necrophorum in primary endodontic infections from a Brazilian population and theirExpand
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. Expand

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. Expand
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. Expand
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. Expand

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. Expand
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. Expand
