1. Effect of Bulgarian propolis on the oral microflora in adolescents with plaque-induced gingivitis
ABSTRACT We compared the effect of two therapeutic approaches (marketed toothpaste and addition of Bulgarian propolis extract to the toothpaste) on gingival inflammation, plaque formation and oral microbial flora on Bulgarian adolescents with moderate plaque-induced gingivitis. The participants were divided randomly into two groups of 35 students. The first

2. Bacterial diversity of symptomatic primary endodontic infection by clonal analysis
Abstract The aim of this study was to explore the bacterial diversity of 10 root canals with acute apical abscess using clonal analysis. Samples were collected from 10 patients and submitted to bacterial DNA isolation, 16S rRNA gene amplification, cloning, and sequencing. A bacterial genomic library was constructed and bacterial diversity was estimated. The

3. Prevalence of periodontopathogens and Candida spp. in smokers after nonsurgical periodontal therapy – a pilot study
Abstract This pilot study aimed to evaluate the influence of smoking on clinical and microbiological parameters after nonsurgical periodontal therapy. Forty-eight subjects were grouped into smokers (SM, n = 24) and nonsmokers (NS, n = 24) and paired according to gender, age, ethnicity, and periodontal status. Both groups received oral hygiene education and s

4. Detection of cfxA2, cfxA3, and cfxA6 genes in beta-lactamase producing oral anaerobes
ABSTRACT Purpose The aim of this study was to identify β-lactamase-producing oral anaerobic bacteria and screen them for the presence of cfxA and BlaTEM genes that are responsible for β-lactamase production and resistance to β-lactam antibiotics. Material and Methods Periodontal pocket debris samples were collected from 48 patients with chronic period

5. Presença de espécies de Porphyromonas e Prevotella na microbiota oral de bovinos com periodontite
Resumo: A periodontite bovina é um processo infeccioso purulento e progressivo associado à presença de biofilme subgengival anaeróbio estrito e facultativo e de incidência em extensas áreas geográficas do Brasil. O trabalho teve por objetivo detectar espécies dos gêneros Porphyromonas e Prevotella presentes na bolsa periodontal de bovinos com lesõe

6. Bacteriological analysis of necrotic pulp and fistulae in primary teeth
Objectives: Primary teeth work as guides for the eruption of permanent dentition, contribute for the development of the jaws, chewing process, preparing food for digestion, and nutrient assimilation. Treatment of pulp necrosis in primary teeth is complex due to anatomical and physiological characteristics and high number of bacterial species present in end

7. Microbial colonization in orthodontic mini-implants
A inflamação peri-implantar contribui para a perda da estabilidade secundária dos mini-implantes ortodônticos. A investigação da colonização microbiana desta área beneficiaria o seu controle e, consequentemente, favoreceria o sucesso dos mini-implantes a longo prazo. Portanto, o objetivo dos autores foi determinar o estabelecimento e evolução do p

8. Microbiological and molecular analysis of Porphyromonas and Fusobacterium species isolated from dogs with and without periodontitis and their relashionship with immunological response / Análise microbiológica e molecular de espécies de Porphyromonas e Fusobacterium isoladas de cães com e sem periodontite e sua relação com a resposta imunológica
A periodontite é uma resposta inflamatória desencadeada por um complexo biofilme constituído por diversos microrganisnos, particularmente por bactérias anaeróbias, tais como Porphyromonas spp. e Fusobacterium spp. Essas bactérias produzem vários fatores de virulência capazes de atuar no início e progressão da doença. Cem amostras subgengivais fora

9. Comunidades microbianas em canais radiculares e abscessos periapicais agudos e suscetibilidade de algumas bacterias anaerobias estritas isoladas / Microbial communities in root canals and acute periradicular abscess and antimicrobial susceptibility of some strict anaerobes
The aim of this study was to examine the profile of microbial communities in necrotic root canals (RC) and acute periradicular abscesses (AP) in paired samples. The antimicrobial susceptibility was determined with E-test for strict anaerobes. Paired samples of RC and PA exudates were collected from 20 subjects and analyzed by terminal restriction fragment le

10. Microbiologic investigation, quantification of endotoxin and antimicrobial susceptibility in primary endodontic infection and the salivary carriage of selected endodontic pathogens / Analise microbiologica, quantificação de endotoxinas de dentes com infecções endodonticas primarias e suscetibilidade antimicrobiana
O conhecimento das espécies microbianas assim como da suscetibilidade das mesmas à terapia endodôntica é importante para o sucesso do tratamento. Sendo assim, a proposta do presente estudo foi: 1) Analisar a microbiota endodôntica de dentes com necrose pulpar e presença de lesão periapical (C1) e correlacionar com os sinais e sintomas clínicos; 2) in

11. Activities of Gemifloxacin (SB 265805, LB20304) Compared to Those of Other Oral Antimicrobial Agents against Unusual Anaerobes
The activities of gemifloxacin (SB 265805, LB20304) and comparator agents were determined by an agar dilution method against 419 clinical strains of less-commonly identified species of anaerobes. Gemifloxacin was generally more active than trovafloxacin against gram-positive strains by one to two dilutions. Peptostreptococci (Peptostreptococcus asaccharolyti

12. Antimicrobial Susceptibilities of Porphyromonas gingivalis, Prevotella intermedia, and Prevotella nigrescens spp. Isolated in Spain
The susceptibilities of 143 Porphyromonas gingivalis, Prevotella intermedia, and Prevotella nigrescens isolates to 18 antimicrobial agents were tested. All P. gingivalis isolates were susceptible. In contrast, some Prevotella spp. (17%) were resistant to β-lactams, erythromycin, clindamycin, or tetracycline and carried resistance genes, ermF or tetQ, or β-
