Simultaneous Detection of Mycobacterium tuberculosis and Mycobacterium avium Co...

Abstract Infection disease caused by nontuberculous mycobacteria (NTM) have been increasingly reported and often manifest with the same symptoms of tuberculosis (TB). The identification of the causative agent is fundamental for the determination of an appropriate therapy, since each species of mycobacteria requires a specific treatment. Thus, rapid and accurate tests to identify mycobacteria of medical interest...

Nontuberculous mycobacteria in patients with suspected tuberculosis and the gen...

ABSTRACT Objective: Nontuberculous mycobacteria (NTM) are a heterogeneous group of bacteria that are widely distributed in nature and associated with opportunistic infections in humans. The aims of this study were to identify NTM in patients with suspected tuberculosis who presented positive cultures and to evaluate the genetic diversity of strains identified as Mycobacterium avium. Methods: We studied pulmonar...

cagE as a biomarker of the pathogenicity of Helicobacter pylori

IntroductionHelicobacter pylori infection is associated with gastro-duodenal diseases. Genes related to pathogenicity have been described for H. pylori and some of them appear to be associated with more severe clinical outcomes of the infection. The present study investigates the role of cagE as a pathogenicity biomarker of H. pylori compare it to cagA, vacA, iceA and babA2 genes and correlate with endoscopic d...

Improving tuberculosis control through the partnership between university and t...

INTRODUCTION: Tuberculosis (TB) control is linked to the availability of qualified methods for microbiological diagnostics; however, microscopy with limited sensitivity is the only method available in many locations. The objective of this study was to evaluate the introduction of culture, drug susceptibility testing (DST), and genotyping in the routine of a Municipal Program of Tuberculosis Control. METHODS: Di...

Evaluation of diagnostic methods for the detection of Helicobacter pylori in ga...

Helicobacter pylori infects nearly 50% of the world's population. This microorganism is accepted as the most important agent of gastritis and as a risk factor for peptic ulcer disease and gastric adenocarcinoma. Currently many diagnostic methods exist for detecting H. pylori, however they all have limitations, thus it is recommend a combination of at least two methods. The aim of this study was to evaluate diag...
