Abstract

Intracellular pathogens, such as bacteria and parasites, have evolved specialized mechanisms to survive and replicate in their host, leading to disorders and diseases. The principle of these mechanisms is to reprogram the microbicidal cell function in order to disable the host cells defence that aims to control and eliminate foreign invaders. Devoid of their defence, cells become permissive to pathogens invasion. The aim of this Research Topic is to highlight and cover recent understanding of mechanisms and molecules used by pathogens to interfere with the microbicidal function of cells. This Research Topic will focus on the reprogramming of the cellular dynamics, the immune response, the phagolysosome biogenesis and the signal transduction pathways bypathogens. Special attention will be made on non-proteic virulence factors, however this Research Topic is not restricted to non-proteic virulence factors.

Abstract

La fièvre Q est une maladie présente dans la plupart des pays. L’homme et plusieurs espèces animales sont sensibles à Coxiella burnetii qui est la bactérie responsable de cette pathologie. Il s’agit donc d’une zoonose qu’on ne doit pas négliger puisque une seule bactérie peut suffire pour transmettre l’infection à l’homme et que les réservoirs primaires de C.burnetii sont les bovins, les ovins et les caprins. Suite à l’épidémie humaine de fièvre Q aux Pays-Bas entre 2007 et 2010, la Wallonie a pris différentes mesures afin de renforcer le contrôle et la surveillance de cette pathologie dans les élevages wallons des ruminants domestiques, en l’occurrence le projet de recherche menée par l’ARSIA en collaboration avec la faculté de médecine vétérinaire de l’université de Liège entre 2012 et 2016, et qui a permis une bonne progression en matière de diagnostique et de contrôle de la maladie au sein des troupeaux infectés.

Abstract

Le taux d’avortements chez les petits ruminants est habituellement estimé à 5 %. En Belgique par exemple, il n’existe pas de recensement systématique de l’avortement pour ce secteur et ce chiffre est actuellement difficilement confirmé.&#13;Selon les dernières études concernant l’avortement des petits ruminants, l’origine multifactorielle a été mise en avant, d’où l’intérêt d’un diagnostic différentiel complet.&#13;La préface de cette étude répertorie les causes infectieuses et non infectieuses de l’avortement en Belgique. Pour chaque facteur, le moyen de transmission, le risque zoonotique, les signes cliniques, les tests de diagnostic, les traitements et la prévention ont été analysés.&#13;L’originalité de ce travail porte principalement sur la réalisation d’un questionnaire en ligne envoyé aux éleveurs de petits ruminants. Le but de ce questionnaire est de réaliser un état des lieux sur l’avortement dans ce secteur en Belgique. Cette étude est une première et n’avait jamais été réalisée auparavant.&#13;L’analyse des résultats de cette étude a permis d’établir le profil des éleveurs de petits ruminants en Belgique (Wallonie), de donner une estimation du nombre d’avortements, de connaître la conduite alimentaire ainsi que les mesures de biosécurité et sanitaires suivies par les éleveurs. Tous ces facteurs ont été analysés afin d’identifier des causes possibles expliquant ce taux d’avortements.&#13;Cette étude a fait également apparaître les mesures qu’il serait judicieux de mettre en œuvre afin d’augmenter le diagnostic et à long terme, de réduire le nombre d’avortements en Belgique.

Abstract

Over 20 years have elapsed since publication of the seminal two volume series entitled Q Fever: The Biology of Coxiella burnetii (edited by J. C. Williams and H. A. Thompson) and Q fever: The Disease (edited by T. J. Marrie) that described the current state of Coxiella burnetii research. The ensuing years have brought the post-genomic era and accompanying technologies that have catalyzed major advances in the field, including milestones discoveries of genetic transformation and host cell-free growth of this former obligate intracellular bacterium. Understanding how the bacterium resists the degradative functions of vacuole, and the host cell functions coopted for successful parasitism, are central to understanding Q fever pathogenesis. Recent achievements in glycomics and proteomics are guiding development of enhanced detection schemes for the bacterium in addition to shedding light on the host immune response to the pathogen.   The book covers the current state-of-the-art knowledge in the selected fields of C. burnetii/Q fever research. Coxiella has matured from a niche organism, investigated by a handful of laboratories worldwide, to a model system to study macrophage parasitism, developmental biology, host-pathogen interactions, and immune evasion/modulation.
