Odontol. vital; (31), 2019
Resumen Objetivo: Evaluar mediante cuantificación de halos de inhibición el efecto antibacteriano de la cáscara y pulpa del capulí (Prunus serotina capulí) y del mortiño (Vaccinium floribundum), sobre cepas de Streptococcus mutans (ATCC 35668) a las 24 y 48 horas, comparado con arándano deshidra...

Evaluation of an antibacterial orthodontic adhesive incorporated with niobium-based bioglass: an in situ study

Abstract This in situ study aimed to evaluate the antibacterial and anti-demineralization effects of an experimental orthodontic adhesive containing triazine and niobium phosphate bioglass (TAT) around brackets bonded to enamel surfaces. Sixteen volunteers were selected to use intra-oral devices with six...

Susceptibility to β-lactams in β-hemolytic streptococci

Rev. argent. microbiol; 50 (4), 2018
Group A (GAS), B (GBS), c (GCS) and G (GGS) β-hemolytic streptococci are important human pathogens. They cause infections of different severity and frequency. Nowadays, after 70 years of use, penicillin is still universally active against GAS, GCS and GGS. However, therapeutic failures have been rec...

Susceptibility of cariogenic microorganisms to phytoconstituents

Braz. j. biol; 78 (4), 2018
Abstract This study aimed to evaluate the in vitro antibacterial activity of the phytochemicals thymol, linalool, and citronellol against Streptococcus mutans, Streptococcus salivarius and Streptococcus oralis. Disk diffusion screening on solid medium and measurement of the diameter of the bacterial grow...

Analysis of the antimicrobial and anti-caries effects of TiF4 varnish under microcosm biofilm formed on enamel

J. appl. oral sci; 26 (), 2018
Abstract Titanium tetrafluoride (TiF4) is known for interacting with enamel reducing demineralization. However, no information is available about its potential antimicrobial effect. Objectives This study evaluated the antimicrobial and anti-caries potential of TiF4 varnish compared to NaF varnish, chlor...

Chemical composition, antioxidant and antibacterial activities of essential oils from leaves and flowers of Eugenia klotzschiana Berg (Myrtaceae)

An. acad. bras. ciênc; 89 (3), 2017
ABSTRACT Many essential oils (EOs) of different plant species possess interesting antimicrobial effects on buccal bacteria and antioxidant properties. Eugenia klotzschiana Berg (pêra-do-cerrado, in Portuguese) is a species of Myrtaceae with restricted distribution in the Cerrado. The essential oils were...

Early-onset neonatal sepsis and the implementation of group B streptococcus prophylaxis in a Brazilian maternity hospital: a descriptive study

Abstract Objectives: To describe early-onset neonatal sepsis (EOS) epidemiology in a public maternity hospital in Brasilia, Brazil. Methods: We defined EOS as a positive blood culture result obtained from infants aged ≤72 hours of life plus treatment with antibiotic therapy for ≥5 days. Inc...

Cymbopogon citratus essential oil: effect on polymicrobial caries-related biofilm with low cytotoxicity

Abstract The objective of this study was to evaluate the effects of Cymbopogon citratus essential oil and its main compound (citral) against primary dental colonizers and caries-related species. Chemical characterization of the essential oil was performed by gas chromatography/mass spectroscopy (GC/MS), ...

Evaluación de la eficacia antimicrobiana del aceite esencial de Minthostachys verticillata y limoneno contra cepas de Streptococcus uberis aislados de mastitis bovina
Evaluation of the antimicrobial efficacy of Minthostachys verticillata essential oil and limonene against Streptococcus uberis strains isolated from bovine mastitis

Rev. argent. microbiol; 48 (3), 2016
Bovine mastitis is a disease that causes great economic losses per year, being Streptococcus uberis the main environmental pathogen involved. The aim of the present study was to determine the minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) of Minthostachys verticil...
