Laboratory tools for tuberculosis control in a setting with a high burden of HIV/AIDS.

Nosocomial transmission of is an important health issue and the detection of tuberculosis (TB) cases is the main tool for controlling this disease. We aimed to assess the possible occurrence of nosocomial transmission of in a reference hospital for HIV/AIDS patients and evaluate both the performance of the Xpert MTB/RIF (Xpert) platform and drug resistance profiles. We evaluated the performance of the Xpert platform.

Genetic Diversity and Molecular Epidemiology of in Roraima State, Brazil.

National border areas are special places for the spread of (MTB). These regions concentrate vulnerable populations and constant population movements. Understanding the dynamics of the transmission of MTB is fundamental to propose control measures and to monitor drug resistance.

Tuberculosis caused by Mycobacterium pinnipedii in a wild South American sea lion Otaria flavescens stranded in southern Brazil.

Tuberculosis (TB) in pinnipeds is typically caused by Mycobacterium pinnipedii, which has also been associated with infections in other species, such as cattle and humans. As a result, this pathogen has zoonotic potential and is a public health concern. In 2016, a female South American sea lion Otaria flavescens in southern Brazil presented with emaciation and severe dyspnea and died within 3 h of capture.

Clonal expansion across the seas as seen through CPLP-TB database: A joint effort in cataloguing Mycobacterium tuberculosis genetic diversity in Portuguese-speaking countries.

Tuberculosis (TB) remains a major health problem within the Community of Portuguese Language Speaking Countries (CPLP). Despite the marked variation in TB incidence across its member-states and continued human migratory flux between countries, a considerable gap in the knowledge on the Mycobacterium tuberculosis population structure and strain circulation between the countries still exists. To address this, we have assembled and analysed the largest CPLP M.
