“…in the subgingival microbiota of periodontitis patients in the Dominican Republic, whereas Ali and co-workers (2) observed a frequency of 61.1% of enterics in the subgingival microbiota of periodontitis subjects from Romania. The species P. aeruginosa and A. baumannii, important etiologic agents of nosocomial infections, have been associated with refractory periodontitis, probably due to their elevated resistance to mechanical and antimicrobial therapies (4,29,34). Another pathogen related to antimicrobial resistance is E. faecalis.…”

The oral cavity may act as a reservoir for several pathogens related to systemic infections. Therefore, the purpose of this study was to determine the prevalence and levels of pathogenic bacteria in the subgingival biofilm of chronic periodontitis lesions and healthy periodontal sites using the checkerboard DNA-DNA hybridization technique. 200 samples of subgingival biofilm from sites with periodontitis (probing pocket depth ≥ 4 mm and /or clinical attachment level ≥ 4 mm) and 200 samples from healthy sites of 14 patients with chronic periodontitis, as well as 200 samples from 3 periodontally healthy patients were obtained. The presence and levels of 11 pathogenic bacteria were determined using whole genomic DNA probes and the checkerboard method, computed for each site and then across sites within each subject group. Significance of differences in clinical and microbiological parameters among groups were examinated using the MannWhitney and Wilcoxon sign tests. The predominant species in all 600 samples included Corynebacterium diphtheriae, Enterococcus faecalis, Staphylococcus aureus, Acinetobacter baumannii and Escherichia coli. In general, most of the species were detected in greater prevalence and levels in sites with and without disease from patients with periodontitis in comparison to the periodontally healthy group. In particular, C. diphtheriae, E. coli, E. faecalis, Pseudomonas aeruginosa and S. aureus were significantly more prevalent and detected in higher counts in diseased sites of patients with periodontal disease compared to healthy subjects (p < 0.05). Clinical signs of disease presented a positive correlation with the species A. baumannii, Streptococcus pyogenes, E. coli, S. aureus and P. aeruginosa. In conclusion, "non-oral" pathogenic bacteria are detected in high prevalence and levels in periodontal sites of chronic periodontitis patients.

“…Up to 90% of enterococcal infections in humans are caused by Enterococcus faecalis (2). Data on oral prevalence of E. faecalis vary widely in different studies (3)(4)(5)(6). The presence of E. faecalis in the oral cavity raises the question of whether the mouth could be a source for infection with this microorganism.…”

Objectives: Refractory periodontitis is the occurrence of additional clinical attachment loss after repeated attempts to control the infection with conventional periodontal therapy. Some microorganisms seem to be involved in the pathogenesis of chronic refractory periodontitis. The prevalence of Enterococcus faecalis in the oral cavity seems to be higher in individuals with periodontitis. Therefore, the present study investigated the presence of E. faecalis in subgingival biofilm of patients with chronic refractory periodontal disease. Study design: Periodontal treatment was instituted for 100 patients suffering from chronic periodontitis. Then samples were obtained from 27 successfully treated and 27 chronic refractory periodontitis subjects and then cultured. Statistical evaluation was performed for descriptive purposes. Results: 27% of the patients had chronic refractory periodontitis. The difference in the presence of E. faecalis in the pockets between the successfully treated (11.1%) and chronic refractory (51.8%) groups by culture methods was statistically significant (P<0.05). Conclusion: Data showed that E. faecalis is probably involved in the pathogenesis of refractory periodontitis. Accurate knowledge about the pathogen and its role in the pathogenesis of refractory infections helps develop effective treating strategies.

ResumoIntrodução: Bactérias associadas ao insucesso do tratamento endodôntico são capazes de adquirir e expressar resistência aos agentes antimicrobianos comumente empregados para tratar infecções, o que torna necessário, em determinadas situações, a realização de testes laboratoriais para detectar a resistência ou a suscetibilidade antimicrobiana desses micro-organismos. Objetivo: avaliar a suscetibilidade antimicrobiana das cepas de Enterococcus faecalis, Enterococcus faecium, Actinomyces viscosus e Staphylococcus aureus isoladas de canais radiculares de dentes com insucesso endodôntico. Material e método: Cepas clínicas de Enterococcus faecalis (n=3), Enterococcus faecium (n=3), Actinomyces viscosus (n=3) e Staphylococcus aureus (n=3), coletadas in vivo de canais radiculares com insucesso endodôntico, foram testadas quanto à suscetibilidade antimicrobiana por meio do método E-test em duplicata, utilizando os antibióticos: Amoxicilina (AC), Rifampicina (RI), Moxifloxacina (MX), Vancomicina (VA), Tetraciclina (TC), Ciprofloxacina (CI), Cloranfenicol (CL), Benzilpenicilina (PG), Amoxicilina + ácido clavulânico (XL), Doxiciclina (DC), Eritromicina (EM) e Azitromicina (AZ). Resultado: Todas as cepas clínicas testadas foram suscetíveis aos antibióticos AC, XL, PG, DC, MX, TC e VA. Todos os isolados das espécies de S. aureus foram suscetíveis aos 12 antibióticos testados. As cepas de E. faecalis, E. faecium e A. viscosus mostraram padrão de suscetibilidade intermediário contra EM. Algumas cepas de E. faecalis e E. faecium foram resistentes a AZ e RI. Conclusão: As cepas clínicas isoladas dos canais radiculares de dentes com insucesso endodôntico mostraram perfis diferentes de suscetibilidade antimicrobiana e nenhum isolado de E. faecalis e E. faecium apresentou-se suscetível a AZ e EM.Descritores: Endodontia; bactéria; antibióticos. AbstractIntroduction: Bacteria associated with failure endodontic treatment are capable of acquiring and expressing resistance against antimicrobial agents usually used to treat infections, which makes necessary, in some cases, laboratory tests in order to detect the resistance or antimicrobial susceptibility of these microorganisms. Objective: to evaluate the antimicrobial susceptibility of Enterococcus faecalis, Enterococcus faecium, Actinomyces viscosus and Staphylococcus aureus strains isolated from root canals of teeth with failure endodontic treatment. Material and method: Enterococcus faecalis (n=3), Enterococcus faecium (n=3), Actinomyces viscosus (n=3) and Staphylococcus aureus (n=3) clinical strains collected in vivo from root-filled canals with failure endodontic treatment thad been their antimicrobial susceptibility tested by the E-test method in duplicate using the antibiotics: Amoxicillin (AC), Rifampicin (RI), Moxifloxacin (MX), Vancomycin (VA), Tetracycline (TC), Ciprofloxacin (CI), Chloranphenicol (CL), Benzilpenicillin (PG), Amoxicillin + clavulanic acid (XL), Doxycycline (DC), Erythromycin (EM) e Azithromycin (AZ). Result: all the clinical strains tested were susceptib...
