Le développement d’une immunité face à un agent pathogène à la suite d’une infection naturelle comporte plusieurs étapes et prend généralement une à deux semaines. Une infection virale entraîne immédiatement une réponse immunit...aire innée, non spécifique, au cours de laquelle les macrophages, les neutrophiles et les cellules dendritiques ralentissent la progression du virus et peuvent même éviter l’apparition de symptômes. Cette réponse non spécifique est suivie d’une réponse adaptative, au cours de laquelle l’organisme produit des anticorps qui se lient spécifiquement au virus. Ces anticorps sont des protéines appelées immunoglobulines. L’organisme produit également des lymphocytes T qui reconnaissent et éliminent les cellules infectées par le virus. Cette réponse adaptative permet parfois d’éliminer le virus de l’organisme et, si elle est suffisamment forte, d’éviter l’aggravation de la maladie ou la réinfection par le même virus. Ce processus est souvent mesuré par la présence d’anticorps dans le sang.

Nat Commun 9, 5370 (2018). https://doi.org/10.1038/s41467-018-07804-8. Mycobacterium ulcerans is the causative agent of Buruli ulcer, a neglected tropical skin disease that is most commonly found in children from West and Central Africa. Despite the severity of the infection, therapeutic options are... limited to antibiotics with severe side effects. Here, we show that M. ulcerans is susceptible to the anti-tubercular drug Q203 and related compounds targeting the respiratory cytochrome bc1:aa3. While the cytochrome bc1:aa3 is the primary terminal oxidase in Mycobacterium tuberculosis, the presence of an alternate bd-type terminal oxidase limits the bactericidal and sterilizing potency of Q203 against this bacterium. M. ulcerans strains found in Buruli ulcer patients from Africa and Australia lost all alternate terminal electron acceptors and rely exclusively on the cytochrome bc1:aa3 to respire. As a result, Q203 is bactericidal at low dose against M. ulcerans replicating in vitro and in mice, making the drug a promising candidate for Buruli ulcer treatment.

Background: Atherosclerotic cardiovascular diseases (ASCVD) including myocardial infarction, stroke and peripheral arterial disease continue to be major causes of premature death, disability and healthcare expenditure globally. Preventing the accumulation of cholesterol-containing atherogenic lipopr...oteins in the vessel wall is central to any healthcare strategy to prevent ASCVD. Advances in current concepts about reducing cumulative exposure to apolipoprotein B (apo B) cholesterol-containing lipoproteins and the emergence of novel therapies provide new opportunities to better prevent ASCVD. The present update of the World Heart Federation Cholesterol Roadmap provides a conceptual framework for the development of national policies and health systems approaches, so that potential roadblocks to cholesterol management and thus ASCVD prevention can be overcome.

The Haiti & Dominican Republic Cholera Operation Plan of Action outlines the Red Cross's strategy to combat cholera on the island of Hispaniola following the 2010 outbreak in Haiti. As part of a 10-year national strategy, the plan includes an initial two-year emergency response (2014-2016) with a bu...dget of 9.9 million Swiss francs. The approach focuses on three key areas: improving water and sanitation by repairing and expanding water systems and constructing sanitation facilities, prevention and hygiene promotion through community education and hygiene training, and preparedness and response by strengthening disease monitoring, training Red Cross volunteers, and prepositioning medical supplies. This initiative, led by the Haitian and Dominican Red Cross in collaboration with international partners and local governments, aims to reduce cholera infections and improve public health on the island.

This National Action Plan addresses actions needed to be taken in order to combat antimicrobial resistance (AMR) in the country. It is obligatory to raise awareness of antimicrobial resistance and promote behavioral change through public communication
programmes that targets human, animal and plant... health. Inclusion of the use of antimicrobial agents and resistance in school curricula will further promote better understanding and awareness from an early age. Antimicrobial Resistance knowledge, surveillance and research will be strengthened through establishing a national surveillance system for antimicrobial resistance, establishing and building capacity for a national reference laboratory and designated laboratories for AMR surveillance, developing a national research agenda on AMR and establishing and supporting a coordinated mechanism that will ensure harmonized AMR guidelines, data management and sharing systems in human, animal and plant health settings.
