Methods for the genetic manipulation of marine bacteria

Genetic manipulation of bacteria is a procedure necessary to obtain new strains that express peculiar and defined genetic determinants or to introduce genetic variants responsible for phenotypic modifications. This procedure can be applied to explore the biotechnological potential associated with environ...

Draft genomes and reference transcriptomes extend the coding potential of the fish pathogen Piscirickettsia salmonis

Background: Draft and complete genome sequences from bacteria are key tools to understand genetic determinants involved in pathogenesis in several disease models. Piscirickettsia salmonis is a Gram-negative bacterium responsible for the Salmon Rickettsial Syndrome (SRS), a bacterial disease that threaten...

Evaluation of the waveone gold and one shape new generation in reducing enterococcus faecalis from root canal

Braz. dent. j; 29 (3), 2018
Abstract The aim of this study was to evaluate the WaveOne Gold and One Shape New Generation systems regarding the bacterial removal from root canals infected with Enterococcus faecalis by comparing them to the conventional WaveOne and One Shape systems. Forty-eight distobuccal root canals of maxillary m...

Comparison of full-mouth scaling and quadrant-wise scaling in the treatment of adult chronic periodontitis

Braz. dent. j; 29 (3), 2018
Abstract In the search for the ideal treatment of periodontal disease various non-surgical techniques should be considered. The objective of this study was to evaluate the efficacy of full-mouth scaling (FMS) by clinical and microbiological parameters. 670 individuals were evaluated with 230 subjects mee...

Microbial load after selective and complete caries removal in permanent molars: a randomized clinical trial

Braz. dent. j; 29 (3), 2018
Abstract The aim of this randomized clinical trial was to compare the remaining microbial load after treatments based on complete and selective caries removal and sealing. Patients with active carious lesions in a permanent molar were randomly allocated into 2 groups: a test group (selective caries remov...

Antifungal activity of linalool in cases of Candida spp. isolated from individuals with oral candidiasis

Braz. j. biol; 78 (2), 2018
Abstract This study analyzed the antifungal activity of phytoconstituents from linalool on Candida spp. strains, in vitro, isolated from patients with clinical diagnoses of oral candidiasis associated with the use of a dental prosthesis. Biological samples were collected from 12 patients using complete d...

Isolamento e perfil enzimático de cães e gatos com dermatofitose atendidos em hospitais veterinários do Recife, Pernambuco

Pesqui. vet. bras; 38 (5), 2018
Os dermatófitos são fungos que podem causar infecções superficiais da pele, cabelo e unhas em humanos e animais. As espécies de dermatófitos mais frequentemente isoladas dos cães e gatos afetados por micoses são Microsporum gypseum e principalmente Microsporum canis. O papel crucial durante o pro...

Disminución en la frecuencia de infección por Helicobacter pylori en endoscopías digestivas altas

Rev. méd. Chile; 146 (5), 2018
Background: Helicobacter pylori (HP) is the most widespread chronic human infection worldwide and the most important pathogenic factor of gastric cancer. The calculated prevalence at the Clinical Hospital of the University of Chile from 2002 to 2005 was 44.9%. Aim: To determine the current prevalence of...

Prevalencia de cepas cagA-positivo en la región de Coquimbo, determinada mediante nested-qPCR en muestras fecales

Rev. méd. Chile; 146 (5), 2018
Background: Helicobacter pylori is the most significant pathogen associated with gastric diseases, including gastric cancer. Infected patients with strains that are CagA-positive generally have worse outcomes than those infected with CagA-negative strains. Patients infected with CagA-positive strains hav...
