13. Reproducibility of sterilized rubber impressions
Moldes, dentaduras e outros dispositivos odontológicos podem estar contaminados com a microflora oral ou outros microorganismos de patogenicidade variada do sangue ou saliva de pacientes. O controle da transmissão de infecção por meio de moldes tem sido tentado de diversas maneiras e, uma vez que a desinfecção é menos eficaz e apresenta muitos obstác

14. Controle químico da microflora oral em pacientes fissurados labiopalatais durante o tratamento ortodôntico-cirúrgico: estudo piloto
O risco de infecção é uma preocupação durante o tratamento ortodôntico-cirúrgico, principalmente em pacientes como os fissurados lábio palatais, pois as condições anatômicas e oclusais contribuem para a proliferação microbiana. Métodos manuais para o controle da microflora oral são muitas vezes insuficientes para a obtenção de uma higiene sa

15. 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

16. Effect of the gastrointestinal microflora on induction and maintenance of oral tolerance to ovalbumin in C3H/HeJ mice.
The effect of the digestive microflora on oral tolerance to ovalbumin was studied by using axenic (germfree) and conventional C3H/HeJ mice. In contrast to reported results of studies with sheep erythrocytes, oral administration of ovalbumin induced tolerance in axenic mice, but the maintenance of tolerance was found to be of shorter duration than was with co

17. Effect of polyethylene glycol-electrolyte lavage solution on intestinal microflora.
The bacterial flora of colonic aspirates taken after oral administration of a polyethylene glycol-electrolyte lavage solution to patients undergoing colonoscopy was analyzed by standard bacteriological methods and DNA hybridization techniques. The data were compared with those for normal feces collected from the same patients the day before treatment. The re

18. IB-367, a Protegrin Peptide with In Vitro and In Vivo Activities against the Microflora Associated with Oral Mucositis
Although the microflora associated with oral mucositis initiated by cytotoxic therapy is not well characterized, several studies suggest that reduction of the microbial load in the oral cavity has some clinical benefit. The MICs of IB-367, a synthetic protegrin analog, ranged from 0.13 to 64 μg/ml for gram-positive bacteria (Streptococcus mitis, Streptococc

19. Suppression of colonic microflora by cefoperazone and evaluation of the drug as potential prophylaxis in bowel surgery.
We evaluated the activity of cefoperazone (CPZ) on the intestinal flora in terms of its use as a single prophylactic drug in colon surgery. Twenty-four healthy male volunteers between the ages of 20 and 40 were assigned to receive either CPZ, oral neomycin-erythromycin, or no antibiotics. A mechanical bowel preparation, Golytely, was also given to each of th

20. Detection of Unculturable Bacteria in Periodontal Health and Disease by PCR
Recently developed molecular methods have made it possible to characterize mixed microflora in their entirety, including the substantial numbers of bacteria which do not grow on artificial culture media. In a previous study, molecular analysis of the microflora associated with acute oral infections resulted in the identification of three phylotypes, PUS3.42,

21. Prevalence of Tetracycline Resistance Genes in Oral Bacteria
Tetracycline is a broad-spectrum antibiotic used in humans, animals, and aquaculture; therefore, many bacteria from different ecosystems are exposed to this antibiotic. In order to determine the genetic basis for resistance to tetracycline in bacteria from the oral cavity, saliva and dental plaque samples were obtained from 20 healthy adults who had not take

22. Colonization of the murine oral cavity by Streptococcus gordonii.
Streptococcus gordonii DL1 (Challis) colonized the oral cavities of BALB/c mice that lacked streptococci, enterococci, and lactobacilli (LF mice) as members of an otherwise complex digestive tract microflora. Conventional mice, in comparison, were refractory to colonization by S. gordonii. Mice that harbored lactobacilli but were free of streptococci and ent

23. Oral infections and septicemia in immunocompromised patients with hematologic malignancies.
To estimate the role of oral infections during septicemic episodes in immunocompromised patients with hematologic malignancies, 78 febrile episodes in 46 patients were monitored with daily clinical and microbiological investigations. The 19 septicemic episodes did not differ from the 59 other febrile episodes in the qualitative composition of the aerobic and

24. Culture-Independent Identification of Periodontitis-Associated Porphyromonas and Tannerella Populations by Targeted Molecular Analysis
Periodontitis is the commonest bacterial disease of humans and is the major cause of adult tooth loss. About half of the oral microflora is unculturable; and 16S rRNA PCR, cloning, and sequencing techniques have demonstrated the high level of species richness of the oral microflora. In the present study, a PCR primer set specific for the genera Porphyromonas
