Zambia has recognised the Public Health threat of antimicrobial resistance and its impact on morbidity and mortality, as well as the subsequent economic consequences. The country has recorded microorganisms which have developed resistance to antimicrobial drugs. Notable among these are; Multidrug Re...sistant Mycobacterium Tuberculosis (MDR), Human Immunodeficiency virus resistant to antiretroviral drugs, Plasmodium resistance to antimalarial drugs, and fungal species showing indications of resistance to antifungal drugs. Emergence of “Superbugs” such as Methicillin Resistant Staphylococcus aureus (MRSA), Extended Spectrum beta-lactam (ESBL) producing Klebsiella pneumoniae and Vancomycin Resistant Enterococci (VRE) have also been reported.

In case of resistance to rifampicin, fluoroquinolones become the preferred category of second-line drugs. Unfortunately, quinolone-resistant strains of Mycobacterium leprae have also been reported in several countries, probably due to the extensive use of quinolones for treating several types of inf...ections. Clofazimine resistance is still rare but this antimicrobial cannot be given alone

COVID-19 es una infección viral aguda caus 101-ada por SARS-CoV-2 que tiene típico compromiso respiratorio y, en ocasiones, puede presentar similitudes clínicas y radiológicas con la tuberculosis pulmonar. Ambas entidades pueden tener desenlace fatal si no son diagnosticadas y tratadas a tiempo. Presentamos una serie de casos en los que se diagnosticó tuberculosis pulmonar y COVID-19 en forma simultánea.

La publicación describe el funcionamiento del método rápido, confiable, sencillo y económico al laboratorio que permita examinar un gran número de muestras a fin de seleccionar a aquellos pacientes que pudieran estar potencialmente infectados con Mycobacterium tuberculosis multirresistente a lo...s medicamentos. El método será aplicado en los laboratorios donde haya sido validado. La versión“ directa” del método Griess debe ser usada por los laboratorios de la DISA como un método rápido de tamizaje para la detección de resistencia a isoniacida y rifampicina. Dicho método se aplicará a muestras respiratorias de pacientes primarios.

La tuberculosis o TB, como se le conoce en inglés, es una enfermedad causada por la bacteria Mycobacterium tuberculosis. Estas bacterias por lo general atacan a los pulmones, pero también pueden atacar otras partes del cuerpo, como los riñones, la columna vertebral y el cerebro. Si no se trata ap...ropiadamente, la tuberculosis puede ser mortal

The Lancet olume 395, ISSUE 10232, P1259-1267, April 18, 2020. Buruli ulcer is a neglected tropical disease caused by Mycobacterium ulcerans infection that damages the skin and subcutis. It is most prevalent in western and central Africa and Australia. Standard antimicrobial treatment with oral rifa...mpicin 10 mg/kg plus intramuscular streptomycin 15 mg/kg once daily for 8 weeks (RS8) is highly effective, but streptomycin injections are painful and potentially harmful. We aimed to compare the efficacy and tolerability of fully oral rifampicin 10 mg/kg plus clarithromycin 15 mg/kg extended release once daily for 8 weeks (RC8) with that of RS8 for treatment of early Buruli ulcer lesions.

Three classess of tests are now recommended in the latest consolidated guideles on tests for tuberculosis infection. It includes for the first-time a new class of Mycobacterium tuberculosis antigen-based skin tests (TBSTs), and the two existing classes of tests: the tuberculin skin test (TST) and t...he interferon-gamma release assays (IGRAs).
IGRAs and TBSTs use Mycobacterium tuberculosis complex specific antigens and represent a significant advancement to TST which has been used for over half a century.

Les objectifs de ce document sont de contribuer à ce que l’ulcère de Buruli (infection
à Mycobacterium ulcerans) soit mieux reconnu et d’inciter à intensifier les efforts pour
détecter les cas à un stade précoce de l’infection. Aujourd’hui, les malades peuvent
être guéris par des... antibiotiques s’ils sont diagnostiqués suffisamment tôt, ce qui
permet d’éviter des souffrances et des incapacités inutiles. Nous espérons que tous les
utilisateurs de ce document participeront à la réalisation de ces objectifs.

Pathogen genomic surveillance has become a priority for public health systems in recent years. Genomic sequencing is increasingly being used to characterize pathogens and monitor important public health priorities (e.g. poliovirus, influenza virus, Mycobacterium tuberculosis and Vibrio cholerae, ant...imicrobial resistance (AMR)). The decrease in cost and time of sequencing and the exponential development of bioinformatic pipelines have played a critical role in integrating pathogen genomics into routine public health surveillance. The coronavirus disease 2019 (COVID-19) pandemic has highlighted the role that sequencing plays in the surveillance of infectious diseases. Sequencing facilitates earlier detection, more accurate investigation of outbreaks, closer real-time monitoring of pathogen evolution and tailored development and evaluation of interventions to inform local to global public health decision-making and action. However, there remains a need to coordinate efforts, leverage and link existing surveillance and laboratory networks and capabilities, and systematically integrate genetic sequence data (GSD) with clinical and epidemiological data to strengthen its utility.
