Introduction: Reports of Mycobacterium tuberculosis resistant to multiple drugs are increasing globally and laboratories are becoming increasingly aware of the need for drug susceptibility testing. In recent years, due ...

Visceral toxocariasis is a serious public health problem with a cosmopolitan distribution. Children are susceptible due to their immature immune system and high risks of infection. Nevertheless, the few completed studies ...

Nontuberculous mycobacteria (NTM) causing human infectious disease have become increasingly common. Rapid and accurate identification to the species level is, therefore, critical. The Speed-Oligo Mycobacteria assay is an ...

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 ...

Justificativa e objetivos: As fluoroquinolonas representam uma classe de antimicrobianos que é frequentemente prescrita no tratamento de infecções do trato urinário (ITU), tanto de origem hospitalar como originárias da ...

Background: Multidrug resistant tuberculosis (MDR-TB) is a major threat for global tuberculosis control. The W-Beijing Mycobacterium tuberculosis genotype has been associated with drug resistance. Elucidation of the ...

RDRio is a novel Mycobacterium tuberculosis lineage of the Latin American– Mediterranean (LAM) family. LAM has been found worldwide but is more predominant in South America. The aim of this study was to assess the presence ...

This study evaluated cross-resistance of Mycobacterium tuberculosis strains to ofloxacin, moxifloxacin, and gatifloxacin and investigated the presence of mutations in gyrA and gyrB. Fluoroquinolone susceptibilities were ...

Justificativa e Objetivos: Apesar de ser utilizado como um método de genotipagem para diferentes microrganismos, poucos estudos relatam a utilização de Multiple-Locus Variable Number of Tandem Repeats Analysis (MLVA) ...

We standardized a method to evaluate the growth kinetics of Mycobacterium tuberculosis by measuring quantitatively the reduction of resazurin by spectrophotometry. Growth curves and the rate of growth of twenty-one M. ...

Justificativa e Objetivos: Helicobacter pylori é uma bactéria Gram negativa que coloniza o estômago de aproximadamente 50% da população humana mundial. Este microrganismo é o principal agente causal de gastrite e um ...

Biotérios são instalações capazes de produzir e manter espécies de animais para pesquisa em diferentes áreas da ciência. Independente da espécie ou linhagem utilizada, é importante que o manejo e a manutenção dos animais ...

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 ...

A series of twenty-three N-acylhydrazones derived from isoniazid (INH 1-23) have been evaluated for their in vitro antibacterial activity against INH- susceptible strain of M. tuberculosis (RG500) and three INH-resistant ...

Considerando a importância das Infecções Hospitalares (IHs) à saúde pública e os desafios que representam aos profissionais na minimização dos fatores de risco, torna-se necessário implementar ferramentas que contribuam ...

As doenças infecciosas ainda são uma das principais causas de morte no mundo, sendo de significativa importância o desenvolvimento de novos compostos antimicrobianos contra diferentes microrganismos. As plantas podem ser ...

Thirty-six plant extracts from the brazilian Atlantic Forest were tested for their antimycobacterial activity against Mycobacterium tuberculosis H37Rv and M. kansasii, using the method REMA in seriate concentrations of 100 ...

Tuberculosis remains one of the major causes of mortality worldwide. The early detection of new cases is an important goal in the program of tuberculosis control. Several methodologies for rapid and accurate laboratorial ...
