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 ...

Intestinal microbiota changes after solid organ transplantation: a systematic review

Clin. biomed. res; 38 (1), 2018
Introduction: The intestinal microbiota may undergo changes after solid organ transplantation. The purpose of this systematic review was to characterize the intestinal microbiota of patients undergoing solid organ transplantation. Methods: MEDLINE, EMBASE and Cochrane Library databases were searched from...

Pleurotus spp. cultivation on Brachiaria sp. straw treatment with alkaline water

Braz. j. microbiol; 49 (supl.1), 2018
Abstract The aim of this research was to evaluate the efficiency of aqueous alkali-treated Brachiaria straw for the cultivation of appropriate species of oyster mushroom. The substrate used in the cultivation of various Pleurotus spp. was soaked for 20 min by using two different procedures: (i) 0.5-2.0% ...

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...

Detection of virulence and β-lactamase encoding genes in Enterobacter aerogenes and Enterobacter cloacae clinical isolates from Brazil

Braz. j. microbiol; 49 (supl.1), 2018
ABSTRACT Enterobacter cloacae and E. aerogenes have been increasingly reported as important opportunistic pathogens. In this study, a high prevalence of multi-drug resistant isolates from Brazil, harboring several β-lactamase encoding genes was found. Several virulence genes were observed in E. aero...

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...

Dynamics of the seasonal airborne propagation of Staphylococcus aureus in academic dental clinics

J. appl. oral sci; 26 (), 2018
Abstract Objective Staphylococcus aureus strains can be disseminated during dental treatments and occasionally lead to the contamination and infection of patients and dentists, which is an important public health problem. The dynamics of the airborne propagation and the genetic diversity of S. aureus is...

Two mechanisms of oral malodor inhibition by zinc ions

J. appl. oral sci; 26 (), 2018
Abstract Objectives The aim of this study was to reveal the mechanisms by which zinc ions inhibit oral malodor. Material and Methods The direct binding of zinc ions to gaseous hydrogen sulfide (H2S) was assessed in comparison with other metal ions. Nine metal chlorides and six metal acetates were exami...
