Manejo actualizado de la diarrea asociada a Clostridium difficile

Gastroenterol. latinoam; 29 (supl.1), 2018
The management of Clostridium difficile (CD) infection has changed in recent years. The latest clinical guidelines and systematic reviews suggest the use of vancomycin orally as the first line of treatment regardless the severity of the crisis (main difference compared to previous recommendations), this ...

Characterization of avian pathogenic Escherichia coli isolated from free-range helmeted guineafowl

Braz. j. microbiol; 49 (supl.1), 2018
Abstract Avian pathogenic Escherichia coli (APEC) isolates from apparently healthy free range helmeted guineafowl were characterized. Most of them had a high frequency of virulence associated genes, multi drug resistance and high pathogenicity. We demonstrated that helmeted guineafowl have potential to t...

Extracellular calcium increases fibroblast growth factor 2 gene expression via extracellular signal-regulated kinase 1/2 and protein kinase A signaling in mouse dental papilla cells

J. appl. oral sci; 26 (), 2018
Abstract We previously reported that elevated extracellular calcium (Ca2+) levels increase bone morphogenetic protein 2 expression in human dental pulp (hDP) cells. However, it is unknown whether extracellular Ca2+ affects the expression of other growth factors such as fibroblast growth factor 2 (FGF2). ...

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...

J. appl. oral sci; 26 (), 2018
ABSTRACT Objective: To evaluate the effect of erosive challenges on the tooth- restoration interface of deciduous teeth treated with different adhesive protocols. Material and Methods: Deciduous molars were cut mesiodistally, then embedded, abraded and polished (n=80). Samples were randomly divided acc...

Effect of γ-lactones and γ-lactams compounds on Streptococcus mutans biofilms

J. appl. oral sci; 26 (), 2018
Abstract Considering oral diseases, antibiofilm compounds can decrease the accumulation of pathogenic species such as Streptococcus mutans at micro-areas of teeth, dental restorations or implant-supported prostheses. Objective To assess the effect of thirteen different novel lactam-based compounds on th...
