Abstract
La tuberculosis (TB) es una enfermedad asociada a la pobreza, con una distribución mundial desigual, registrándose las mayores tasas en las regiones con menos recursos. Sin embargo, ha pasado a considerarse un desafío global fruto del incremento del fenómeno migratorio desde países de baja renta hacia países desarrollados. Este trabajo surge como intento de modificar el modo local de enfocar el análisis de la transmisión de esta enfermedad, adaptándonos al nuevo escenario globalizado, con el cometido de responder tanto a retos identificados en los países de origen de la migración como a los de los países de destino. En los países de origen de la migración los principales retos son metodológicos. Dichos países carecen de medios para implementar las tecnologías moleculares y genómicas disponibles para el estudio de la transmisión de la TB. Tratando de compensar la brecha de conocimiento existente entre el origen y destino de los ejes migratorios, hemos desarrollado soluciones metodológicas que recorren los distintos niveles de discriminación requeridos para el análisis genotípico de Mycobacterium tuberculosis (MTB), adaptadas a la realidad de estos entornos donde frecuentemente el cultivo de MTB no es posible...
Tuberculosis (TB) is a poverty related disease. Its global distribution is uneven, with the highest rates observed in regions with scarce resources. Nevertheless, TB has become a worldwide challenge due to the increased migration flow from low-income countries to developed ones. The aim of this work is to help change the currently local approach of the analysis of TB transmission, adapting to new global scenario, by answering to the challenges identified both in the countries of origin and countries of destination of migration.The main challenges in the countries of origin are the methodological ones. In these countries, there is a scarcity of resources for implementing the currently available molecular and genomic technology to study TB transmission. Aiming to balance the knowledge gap between origin and destination regions of the migratory axes, we have developed methodological solutions for the different levels of discrimination to allow genotypic analysis of Mycobacterium tuberculosis (MTB), adapted to the reality of these settings where MTB cultures are frequently not available...
