1. Combined immunodeficiencies
Abstract Objectives: Inborn Errors of Immunity (IEI), also known as primary immunodeficiencies, correspond to a heterogeneous group of congenital diseases that primarily affect immune response components. The main clinical manifestations comprise increased susceptibility to infections, autoimmunity, inflammation, allergies and malignancies. The aim of this

2. Nontuberculous mycobacterial infection in a tertiary care center in Mexico, 2001-2017
ABSTRACT Introduction: Nontuberculous mycobacteria (NTM) comprise several pathogens with a complex profile of virulence, diverse epidemiological and clinical patterns as well as host specificity. Recently, an increase in the number of NTM infections has been observed; therefore, the objective of this study was to evaluate the clinical characteristics and ou

3. Infecção urinária por Mycobacterium abscessus: relato de caso
Resumo Infecção do trato urinário é um sério problema de saúde pública que acomete predominantemente as mulheres. Em homens, está mais relacionada com hiperplasia prostática e cateterismo vesical. A tuberculose urogenital cursa com sintomas inespecíficos e o diagnóstico pode ser aventado na presença de leucocitúria estéril, e infecção recorre

4. Characteristic profile of antibody responses to PPD, ESAT-6, and CFP-10 of Mycobacterium tuberculosis in pulmonary tuberculosis suspected cases in Surabaya, Indonesia
Abstract Accurate and rapid diagnostic tools are important aspects of managing tuberculosis (TB) cases appropriately. However, the sensitivity and specificity of diagnostic kits based on immune response such as the tuberculin skin test (TST) and interferon gamma release assay (IGRA) are still debated. Thus, the exploration and assessment of specific biomarke

5. Synthesis and Biological Evaluation of New Eugenol-Derived 1,2,3- Triazoles as Antimyco bacterial Agents
Eugenol has diverse biological properties including antimycobacterial activity, and the triazole ring is an important heterocycle in antimycobacterial compounds. Therefore, this research aimed to synthesize novel eugenol-derived 1,2,3-triazole as antimycobacterial agents with interesting cytotoxic profile and pharmacological assets. Sixteen compounds were ob

6. Potencial do teste IGRA (Interferon Gama Release Assay) para o diagnóstico de tuberculose ocular. Revisão e análise comparativa com o teste tuberculínico cutâneo (PPD)
Resumo A detecção precisa da infecção latente por tuberculose está se tornando cada vez mais importante devido ao aumento do uso de medicamentos imunossupressores e da epidemia do vírus da imunodeficiência humana, o que aumentou o risco de reativação à tuberculose ativa (TB). O Teste IGRA QuantiFERON® TB Gold apresenta vantagens frente ao teste de

8. Pulmonary nontuberculous mycobacterial infections: presumptive diagnosis based on the international microbiological criteria adopted in the state of São Paulo, Brazil, 2011-2014
RESUMO Objetivo: As micobacterioses pulmonares são doenças causadas por micobactérias não tuberculosas (MNTs), cujo diagnóstico microbiológico envolve o isolamento e a identificação da mesma espécie a partir de pelo menos duas amostras de escarro, uma de lavado brônquico ou uma de biópsia pulmonar. O objetivo do presente estudo foi determinar as

9. Increase in the diagnosis of mycobacteremia after the implementation of semi-automated blood culture at a Brazilian public health laboratory
Abstract INTRODUCTION The prevalence of hematogenous dissemination of mycobacteria is high in immunosuppressed patients. The isolation of mycobacteria in culture remains the standard procedure. METHODS This is a cross-sectional study based on the results of solid (Löwenstein-Jensen medium) and semi-automated liquid (BACTEC 9240) blood cultures, obtained

10. Fast detection of Mycobacterium tuberculosis in culture-positive sputum samples by nitrate reductase activity
ABSTRACT Microscopy and bacterial culture are the main tools in the diagnosis of tuberculosis. Since the slow growth of Mycobacterium tuberculosis impairs rapid diagnosis strategies, especially in countries where the latter are the only available resources, the ongoing development of new and inexpensive tools based on mycobacterial metabolism optimizing grow

11. Nontuberculous mycobacteria in milk from positive cows in the intradermal comparative cervical tuberculin test: implications for human tuberculosis infections
ABSTRACT Although the tuberculin test represents the main in vivo diagnostic method used in the control and eradication of bovine tuberculosis, few studies have focused on the identification of mycobacteria in the milk from cows positive to the tuberculin test. The aim of this study was to identify Mycobacterium species in milk samples from cows positive to

12. Complete plasmid sequence carrying type IV-like and type VII secretion systems from an atypical mycobacteria strain
The genus Mycobacterium is highly diverse and ubiquitous in nature, comprehending fast- and slow-growing species with distinct impact in public health. The plasmid-mediated horizontal gene transfer represents one of the major events in bacteria evolution. Here, we report the complete sequence of a 160,489 bp circular plasmid (pCBMA213_2) from an atypical and
