Characterization of clinical isolates of Mycobacterium tuberculosis from indigenous peoples of Colombia.

Introduction: Tuberculosis continues to be a public health priority. Indigenous peoples are vulnerable groups with cultural determinants that increase the risk of the disease.

Objective: To determine molecular epidemiology and phenotypical features and of Mycobacterium tuberculosis isolates from indigenous people in Colombia during the period from 2009 to 2014.

Resistant tuberculosis in children under 15 years of age, Colombia 2010-2015.

Introduction: Tuberculosis in children is a recent transmission reflection in the community. It is estimated that every year one million children get sick in the world because of this. In Colombia, 291 cases were notified in 2015.

Mycobacterioses identified in the National Reference Laboratory of Colombia from 2012 to 2016.

Introduction: In recent years, there has been an increase in the prevalence of mycobacterioses caused by non-tuberculous mycobacteria, which are considered as emerging pathogens. Their presence depends on several factors such as the clinical history, the health status of the affected person, and the presence of these microorganisms in the water, the soil, and the animals, among others. Objective: To describe the mycobacteria and the etiological agent identified in isolates received at the Laboratorio Nacional de Referencia de Micobacterias of the Instituto Nacional de Salud between 2012 and 2016.

[Estimation of underreporting of Chikungunya virus infection cases in Girardot, Colombia, from November, 2014, to May, 2015].

Introduction: Chikungunya virus infection in Colombia became epidemic in 2015. It is estimated that there is underreporting of cases to the public health surveillance system which can induce bias in epidemiological projections for decision making, a serious problem, as it veils the real magnitude and actual epidemiological importance of this disease.

Objective: To estimate the underreporting of cases of chikungunya infection in the municipality of Girardot, Cundinamarca, from November, 2014, to May, 2015.

[Prevalence of Mycobacterium tuberculosis resistance to quinolones and injectables in Colombia, 2012-2013].

[Characterization of clinical isolates of Mycobacterium tuberculosis from HIV positive individuals in Colombia, 2012].

Introduction: One third of the increase in tuberculosis cases is attributed to the spread of HIV. In 2012, 1,397 HIV-associated tuberculosis cases were reported in Colombia, i.e.

[Tuberculosis and drug-resistance tuberculosis in prisoners. Colombia, 2010-2012].

Objective: To characterize tuberculosis drug-resistance using anti-tuberculosis drug-sensitivity tests in Colombian prisoners.

Methods: Descriptive-retrospective analyses were performed on cases of tuberculosis in prisoners. Samples were evaluated by the National Reference Laboratory.

[Evaluation of the BD MGITTM technique for identifying the Mycobacterium tuberculosis complex].

Objectives: To evaluate BD MGITTM TBc® technique for identifying the Mycobacterium tuberculosis complex using isolates obtained in liquid and solid media.

Methods: A descriptive study was conducted in which 117 isolates were analyzed by the immune-chromatography technique obtained from solid and liquid cultures to identify the Mycobacterium tuberculosis complex. The kappa coefficient was calculated to determine the degree of agreement between the two methods .
