1. Oral microbiota and their antibiotic susceptibility in free-living monkeys in Goiás State, Brazil: Repercussions for injuries in humans
Abstract INTRODUCTION: Goiás State, which is in the midwest region of Brazil, has several urban forests. This fact, along with the expansion of urban areas within the limits of Forest Conservation Units, increases the contact between humans and wildlife, such as capuchin monkeys. The impulsive behavior of these animals and the scarcity of food cause them

2. Effects of chlorhexidine preprocedural rinse on bacteremia in periodontal patients: a randomized clinical trial
Abstract Objective: Single dose of systemic antibiotics and short-term use of mouthwashes reduce bacteremia. However, the effects of a single dose of preprocedural rinse are still controversial. This study evaluated, in periodontally diseased patients, the effects of a pre-procedural mouth rinse on induced bacteremia. Material and Methods: Systemically hea

3. Bioassay-guided fractionation and antimicrobial and cytotoxic activities of Cassia bakeriana extracts
ABSTRACT The antimicrobial potential of extracts of bark and leaves of Cassia bakeriana Craib, Fabaceae, against aerobic and anaerobic oral bacteria was evaluated by the microdilution broth method. For crude ethanol extracts and organic fractions tested, the bark dichloromethane phase showed a significant antibacterial effect, with MIC values ranging from 12

4. 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

5. 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

6. Nasal, oral and rectal microbiota of Black lion tamarins (Leontopithecus chrysopygus)
Black lion tamarins (Leontopithecus chrysopygus) are endangered callithrichids. Their conservation may require future translocations or reintroductions; however these approaches involve risks of pathogen introduction in the environment and stress-related opportunistic infections in these animals. In order to screen for opportunistic and potential pathogenic

7. Validation of the anti-bacteremic efficacy of an essential oil rinse in a Brazilian population: a cross-over study
This cross-over study was conducted to assess the germ-killing efficacy of an essential oil mouthrinse (EOM) by determining the blood levels of microorganisms associated with induced bacteremia and investigating the prevalence of this event in Brazilians with mild-to-moderate gingivitis. Thirty four (31.19%) subjects positive for bacteremia induced by chewin

8. Microbiota associated with chronic osteomyelitis of the jaws
Chronic osteomyelitis of maxilla and mandible is rare in industrialized countries and its occurrence in developing countries is associated with trauma and surgery, and its microbial etiology has not been studied thoroughly. The aim of this investigation was to evaluate the microbiota associated with osteomyelitis of mandible or maxilla from some Brazilian pa

9. 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

10. Caracterização das atividades proteolíticas da bactéria anaeróbia fusobacterium nucleatum
Foram determinadas as atividades proteolíticas do bacilo anaeróbio Fusobacterium nucleatum, presente em várias infecções oral e sistêmica humana. As reações foram otimizadas quanto a pH, temperatura, tempo de reação, volume da fonte de enzima e concentração de substrato. Foram utilizados os substratos sintéticos b-naftilamida (Cys-Na, Ser-Na, Le

11. Analise microbiologica de canais radiculares e radiografica de dentes de cães com lesão periapical induzida
The value of dogs in endodontic research is well known by the regularity of their use. Many investigations are conducted in order to observe periapical response and repair on the periapical tissues of this experimental model. Microorganisms are the main etiological agents in pulpal and periapical disorders, therefore comprehension of the dog root canal micro

12. Microbiota in chagasic megaesophagus / Microbiota no megaesôfago chagásico.
The stasis of saliva and swallowed food in the esophageal lumen of patients with chagasic megaesophagus causes: (1) bacterial overgrowth in the esophageal lumen, (2) recurring pulmonary aspirations and respiratory infections, (3) increased risk of surgical or endoscopic procedures if perforation occurs by the major possibility of contamination, and (4) the d
