As inclusion criteria, complete original articles, with in vitro experimental tests with the application of selected anesthetics and bacteria of the genus Staphylococcus spp.

Orange juice containing Pediococcus acidilactici CE51 modulates the intestinal microbiota and reduces induced inflammation in a murine model of colitis.

The management of inflammatory bowel diseases has been widely investigated, especially ulcerative colitis. Thus, studies with the application of new probiotic products are needed in the prevention/treatment of these clinical conditions. The objective of this work was to evaluate the effects of probiotic orange juice containing Pediococcus acidilactici CE51 in a murine model of colitis.

Quercetin-loaded chitosan nanoparticles as an alternative for controlling bacterial adhesion to urethral catheter.

Objectives: The present study aimed to assess the antimicrobial and antiadhesion behavior of quercetin-loaded chitosan nanoparticles in Escherichia coli and Staphylococcus aureus multidrug-resistant isolates.

Methods: The ionic gelation method was used to prepare chitosan nanoparticles loaded with quercetin. The antimicrobial and antibiofilm effects were observed by minimum inhibitory concentration (MIC), plate count, crystal violet assay, and the matrix exopolysaccharide dosages.

Unravelling the effects of the food components ascorbic acid and capsaicin as a novel anti-biofilm agent against .

This study aimed to evaluate the influence of capsaicin and ascorbic acid on the physiology of biofilm formation and dispersion. The influence of the ATCC 25922 biofilm and five isolates were observed in the presence of sodium hypochlorite 2.5 mM and subinhibitory concentrations of capsaicin (7 mM) and ascorbic acid (100 mM).

Comparative Study Of Genetic Diversity, Virulence Genotype, Biofilm Formation And Antimicrobial Resistance Of Uropathogenic (UPEC) Isolated From Nosocomial And Community Acquired Urinary Tract Infections.

Introduction: is a Gram-negative opportunistic human pathogen, which has aroused considerable medical interest for being involved in cases of urinary tract infection.

Aim: Characterize the isolated both in the hospital and in the community.

Methodology: A total of 200 isolated in urine samples from hospital and community were evaluated in biofilm formation assay and hydrophobicity MATS method.

Determination of antimicrobial susceptibility and biofilm production in Staphylococcus aureus isolated from white coats of health university students.

This study aimed at detecting Staphylococcus aureus from white coats of college students and characterizing antimicrobial susceptibility and biofilm production. Bacterial samples (n = 300) were obtained from white coats of 100 college students from August 2015 to March 2017 S. aureus was isolated and it´s resistance profile was assessed by antimicrobial disk-diffusion technique, screening for methicillin-resistant Staphylococcus aureus (MRSA), detection of mecA gene by PCR, and determination of staphylococcal cassette chromosome mec (SCCmec) by multiplex PCR.

Universal gestational screening for Streptococcus agalactiae colonization and neonatal infection - A systematic review and meta-analysis.

The review aimed to analyze the evidence of the correlation between universal screening for Streptococcus agalactiae colonization in pregnant women and early onset Group B neonatal infection. The research followed the descriptors "screening", "pregnancy", "Streptococcus agalactiae" and "neonatal infections" on the Pubmed, scielo and LILACS databases, for studies published in English between January 1st, 2008 and April 24th, 2018. A total of 200 articles were found, of which 198 were excluded.

Different methods to quantify Listeria monocytogenes biofilms cells showed different profile in their viability.

Listeria monocytogenes is a foodborne pathogen able to adhere and to form biofilms in several materials commonly present in food processing plants. The aim of this study was to evaluate the resistance of Listeria monocytogenes attached to abiotic surface, after treatment with sanitizers, by culture method, microscopy and Quantitative Real Time Polymerase Chain Reaction (qPCR). Biofilms of L.

The development of animal infection models and antifungal efficacy assays against clinical isolates of Trichosporon asahii, T. asteroides and T. inkin.

The present study developed Galleria mellonella and murine infection models for the study of Trichosporon infections. The utility of the developed animal models was demonstrated through the assessment of virulence and antifungal efficacy for 7 clinical isolates of Trichosporon asahii, T. asteroides and T.

Unraveling microbial biofilms of importance for food microbiology.

The presence of biofilms is a relevant risk factors in the food industry due to the potential contamination of food products with pathogenic and spoilage microorganisms. The majority of bacteria are able to adhere and to form biofilms, where they can persist and survive for days to weeks or even longer, depending on the microorganism and the environmental conditions. The biological cycle of biofilms includes several developmental phases such as: initial attachment, maturation, maintenance, and dispersal.

Effect of Bacteriocins and Conditions that Mimic Food and Digestive Tract on Biofilm Formation, In Vitro Invasion of Eukaryotic Cells and Internalin Gene Expression by Listeria monocytogenes.

In this report, Listeria monocytogenes isolates were evaluated for their ability to form biofilms, for adhesion/invasion of eukaryotic cells and for differential expression of internalin A (inl A) gene, which is related to virulence potential. The presence of bacteriocins of lactic acid bacteria and incubation at 5 °C were the main factors that influenced biofilm formation by L. monocytogenes, in comparison with BHI (control).
