2. Doxycycline-containing glass ionomer cement for arresting residual caries: an in vitro study and a pilot trial
Abstract In a previous study, we demonstrated that the incorporation of doxycycline hyclate (DOX) into resin-modified glass ionomer cement (RMGIC) inhibited important cariogenic microorganisms, without modifying its biological and mechanical characteristics. In this study, we keep focused on the effect of that experimental material as a potential therapy for

3. Microbial investigation of biofilms recovered from endotracheal tubes using sonication in intensive care unit pediatric patients
Abstract Objectives To compare cultured microorganisms identified on endotracheal tubes biofilms through sonication technique with traditional tracheal aspirate collected at extubation of pediatric intensive care unit patients. Methods Demographic and epidemiological data were analyzed to identify factors possibly related with the microbiological profile o

4. Follow-up after infants younger than 2 months of age with urinary tract infection in Southern Israel: epidemiologic, microbiologic and disease recurrence characteristics
Abstract Background The timing of most recurrences after neonatal urinary tract infection is during the first year of life, with peak incidence 2–6 months after the initial infection. Information on the microbiologic characteristics of recurrent urinary tract infection episodes in relation to the microbiology of the initial episodes is limited. Objective

5. Co-transmission of Rahnella aquatilis between hospitalized patients
ABSTRACT Rahnella aquatilis is an environmental Gram-negative bacillus that is rarely reported as human pathogen, being mainly associated with infections in immunocompromised patients. Herein we describe two cases ofR. aquatilis isolates recovered from endotracheal aspirate cultures of different patients in a tertiary hospital located in the city of São Pau

6. Development of a novel resin with antimicrobial properties for dental application
The adhesion of biofilm on dental prostheses is a prerequisite for the occurrence of oral diseases. Objective: To assess the antimicrobial activity and the mechanical properties of an acrylic resin embedded with nanostructured silver vanadate (β-AgVO3). Material and Methods: The minimum inhibitory concentration (MIC) of β-AgVO3 was studied in relation t

7. Impetigo - review
Impetigo is a common cutaneous infection that is especially prevalent in children. Historically, impetigo is caused by either group A β-hemolytic streptococci or Staphylococcus aureus. Currently, the most frequently isolated pathogen is S. aureus. This article discusses the microbiologic and virulence factors of group A β-hemolytic streptococci and Staphyl

8. Influence of disinfectant solutions on test materials used for the determination of masticatory performance
Masticatory function can be evaluated objectively as the capacity of an individual to fragment solid food after a fixed number of chewing cycles, the so-called masticatory performance (MP). The objective of this study was to evaluate the reliability of four different test materials (Optosil, Optocal, Zetapuls, and Perfil) and five disinfection protocols by a

10. Impact of the introduction of an automated microbiologic system on the clinical outcomes of bloodstream infections caused by Enterobacteriaceae strains
INTRODUCTION: Enterobacteriaceae strains are a leading cause of bloodstream infections (BSI). The aim of this study is to assess differences in clinical outcomes of patients with BSI caused by Enterobacteriaceae strains before and after introduction of an automated microbiologic system by the microbiology laboratory. METHODS: We conducted a retrospective coh

11. Caracterização microbiológica, parâmetros fermentativos e estabilidade aeróbia em silagens de forragens tropicais com aditivos microbianos / Microbiologic characterization, fermentative parameters and aerobic stability of tropical forage silages with microbial additives
Foram realizados dois experimentos para avaliação de aditivos microbianos na ensilagem de forragens tropicais. No primeiro experimento avaliou-se o efeito de doses crescentes de Lactobacillus buchneri, em diferentes tempos de armazenamento, sobre o valor nutritivo, perfil fermentativo e estabilidade aeróbia de silagens de milho. No segundo experimento ava

12. Austrian syndrome in the context of a fulminant pneumococcal native valve endocarditis
This is the case of a young male suffering from Austrian syndrome, which is the triad of endocarditis, meningitis, and pneumonia due to invasive S. pneumoniae infection. He reported recurrent fever for six months without any antibiotic treatment, which may have determined the further course of the syndrome. Echocardiography revealed massive native valve endo
