13. Estudo in vivo da infiltração coronaria em dentes de cães tratados endodonticamente e protegidos por diferentes materiais / In vivo study of the coronal leakage in endodontically treated dog s teeth protected by different materials
This in vivo study evaluated the microbial coronal leakage in dogs endodontically treated teeth, post space preparation and with the remaining filling protected or not with different materiais. A hundred thirty six root canais of incisives and pre-molars of 6 dogs were used. After the anesthesia of the animais, these teeth were endodontically prepared. Hundr

14. Efeito da sanitizaÃÃo e da embalagem na qualidade de goiabas (Psidium guava L.) cv. Paluma minimamente processadas
Minimally processed products are defined as those that have suffered small modifications without greatly changing their freshlike properties. The objective of this work was to evaluate the effect of sanitization on the overral quality of guavas minimally processed. Inially, it was made a consumer survey in supermarket to verify the preference on cut form and

15. Use of a molecular tool for the evaluation of Listeria monocytogens in minimally processed vegetable salad. / Emprego de um método molecular para avaliar a presença de Listeria monocytogenes em saladas de hortaliças folhosas minimamente processadas.
The increasing demand for fresh fruits and vegetables, associated with the desire of convenient goodies, is causing an expansion on the market share of minimally processed products (MP). Minimal processing includes operations such as washing, cutting, peeling and packaging of the product. Amongst pathogenic microorganisms that can be transmitted by MP vegeta

16. Avaliação clinica e microbiologica da periodontite e peri-implantite induzidas : estudo em cães
The purpose of this study was to evaluate and to compare the progression of experimental periodontitis and peri-implantitis induced by ligature technique in five dogs and was used the PCR detection method to investigated the presence of P. gingival is, B. forsythus, A. actinomycetemcomitans, P. intermedia and P. nigrescens, before and after periodontitis and

17. Quantitative Microbiologic Models for Preterm Delivery
Preterm delivery (PTD) is the leading cause of infant morbidity and mortality in the United States. An epidemiological association between PTD and various bacteria that are part of the vaginal microflora has been reported. No single bacterial species has been identified as being causally associated with PTD, suggesting a multifactorial etiology. Quantitative

18. Efficacy and safety of mercuric oxide in the treatment of bacterial blepharitis.
A double-masked, placebo-controlled, randomized study was done to assess the safety and clinical and quantitative microbiologic efficacy of 1% mercuric oxide (yellow) ophthalmic ointment in the treatment of eyelid infections, i.e., bacterial blepharitis. A total of 39 patients with bacterial counts and clinical signs indicative of eyelid infection were treat

19. Extended-Spectrum β-Lactamase Enzymes in Clinical Isolates of Enterobacter Species from Lagos, Nigeria
Over a 9-month period, 8 of 40 nonduplicate isolates of Enterobacter spp. producing extended-spectrum β-lactamase (ESBL) were detected for the first time from two hospitals in Lagos, Nigeria. Microbiologic and molecular analysis confirmed the presence of ESBL. Only four isolates transferred ESBL resistance as determined by the conjugation test, and pulsed-f

20. Detection of methicillin resistance in staphylococci by using a DNA probe.
A DNA probe derived from the PBP 2a gene of the methicillin-resistant Staphylococcus aureus COL was compared with phenotypic microbiologic tests for its ability to identify methicillin-resistant and -susceptible staphylococci. Lysates were applied to nitrocellulose with a dot blot apparatus. Isolates tested were both S. aureus and coagulase-negative staphylo

21. Pharmacodynamics of intravenous ciprofloxacin in seriously ill patients.
Seventy-four acutely ill patients were treated with intravenous ciprofloxacin at dosages ranging between 200 mg every 12 h and 400 mg every 8 h. A population pharmacokinetic-pharmacodynamic analysis relating drug exposure (and other factors) to infectious outcome was performed. Plasma samples were obtained and assayed for ciprofloxacin by high-performance li

22. Effects of Rapid Detection of Bloodstream Infections on Length of Hospitalization and Hospital Charges
Current automated continuous-monitoring blood culture systems afford more rapid detection of bacteremia and fungemia than is possible with non-instrument-based manual methods. Use of these systems has not been studied objectively with respect to impact on patient outcomes, including hospital charges and length of hospitalization. We conducted a prospective,

23. Effects of supraphysiologic temperature and broth dilution on serum protein binding.
Pooled human serum, unheated (UU) and heated at 56 degrees C for 30 (HU-30) and 60 (HU-60) min, and these media diluted 1:1 with broth (UD, HD-30, and HD-60) were used to assess the effects of supraphysiologic temperature and broth dilution on the serum protein binding of ceftriaxone. Protein binding was determined by ultrafiltration and subsequent high-perf

24. Correlation of pharmacodynamic parameters of five beta-lactam antibiotics with therapeutic efficacies in an animal model.
The MIC is the main microbiologic parameter used to predict the efficacies of antibiotics. However, it is well known that MICs may vary according to the inoculum size used (inoculum effect), especially with some beta-lactam antibiotics. In order to correlate the pharmacologic and microbiologic properties of some beta-lactams, an experimental model of intrape
