During the last decade, there has been increasing awareness of the massive number of microorganisms, collectively known as the human microbiota, that are associated with humans. This microbiota outnumbers the host cells by approximately a factor of ten and contains a large repertoire of microbial genome-encoded metabolic processes. The diverse human microbiota and its associated metabolic potential can provide the host with novel functions that can influence host health and disease status in ways that still need to be analyzed. The microbiota varies with age, with features that depend on the body site, host lifestyle and health status. The challenge is therefore to identify and characterize these microbial communities and use this information to learn how they function and how they can influence the host in terms of health and well-being. Here we provide an overview of some of the recent studies involving the human microbiota and about how these communities might affect host health and disease. A special emphasis is given to studies related to tuberculosis, a disease that claims over one million lives each year worldwide and still represents a challenge for control in many countries, including Colombia.

The use of carbon nanotubes decorated with metallic particles is having a great impact as a reinforcing nanomaterial in different applications. In this work, multiwalled carbon nanotubes (MWCNTs) were synthesized by chemical vapor deposition and decorated with silver nanoparticles via in-situ. The MWCNTs-Ag were characterized by SEM, TEM, Raman, XRD, and XPS. The results indicated that the silver nanoparticles dispersed homogeneously on the outer surface of the MWCNTs.

RESUMEN Los tejidos reforzados con nanoestructuras se ha convertido en un área de la investigación que busca contener la transmisión de microorganismos relacionados con las infecciones asociadas a la atención en salud, un problema de salud pública conlleva una alta carga de morbimortalidad en la población y pérdidas millonarias de recursos económicos. Las nanopartículas metálicas y óxido metálicas son agentes antimicrobianos que han cobrado importancia por su amplia aplicación. Esta revisión narrativa examina la evidencia científica de textiles funcionales con propiedades antimicrobianas como una estrategia para contener la transmisión de microorganismos relacionados con infecciones asociadas a la atención en salud, a partir del contexto de los textiles como fuente de contaminación e infección y los mecanismos antimicrobianos de las diferentes nanopartículas usadas como reforzantes para lograr un textil funcional. El desarrollo de la nanotecnología permite el progreso en diferentes campos de la ciencia y oportunidades en el ámbito de textiles funcionales. ABSTRACT Fibers reinforced with nanostructures has become an area of research that seeks to contain the transmission of microorganisms connected with health care associated infections, a public health problem that carries high burden of morbidity and mortality in the population and millions of dollars lost. Metal and metal oxide nanoparticles are known to be antimicrobial agents with wide application. This narrative review aims to examine the scientific evidence of functional textiles with antimicrobial properties as a strategy to contain the transmission of microorganisms related with health care associated infections, starting from the context of textiles as a source of contamination and infection, and the antimicrobial mechanisms of the different nanoparticles used as reinforcers to achieve a functional textile. The development of nanotechnology will allow progress in different fields of science and opportunities in functional textiles. RESUMO O tecido reforçado nanoestrutural tornou-se uma área de pesquisa que busca conter a transmissão de microorganismos relacionados a infecções associadas com cuidados de saúde, um problema de saúde pública carrega uma carga elevada de morbidade e mortalidade na população e perdas milionários de recursos econômicos. As nanopartículas metálicas e os óxidos metálicos são agentes antimicrobianos que ganharam importância devido à sua ampla aplicação. Esta revisão narrativa examina a evidência científica de têxteis funcionais com propriedades antimicrobianas como estratégia para conter a transmissão de microorganismos relacionados a infecções associadas com cuidados de saúde, do contexto de têxteis como fonte de contaminação e infecção e mecanismos antimicrobianos de as diferentes nanopartículas utilizadas como reforçadores para atingir um tecido funcional. O desenvolvimento da nanotecnologia permite o progresso em diferentes campos da ciência e oportunidades no campo dos têxteis funcionais.
