Dans ce travail, nous nous sommes intéressés à l’étude des infections à Anaplasmataceae chez les animaux et leurs tiques afin de caractériser au mieux ces infections animales et humaines et décrire de nouvelles espèces. Nous avons tout d’abord proposé un système de diagnostic moléculaire qui couple une qPCR suivie d’amplification et un séquençage ciblant le gène 23S ARNr. Puis, au long de ce travail, nous avons proposé d’autres amorces ciblant d’autres gènes incluant la sous unité ribosomal bêta (rpoB), la protéine du choc thermique (groEl), et le 16S ARNr. Notre objectif a été de sélectionner et d’identifier les différentes espèces impliquées ou non dans des pathologies chez les animaux et mettre en évidence leur vecteur. Au cours de ces travaux, nous avons eu accès à différents prélèvements de sang et des tiques en provenance de diverses régions du monde incluant la France métropolitaine et d’outre-mer, l’Algérie, le Niger, la Côte d’Ivoire, le Sénégal et le Pakistan. Nos investigations ont permis d’identifier différentes espèces d’Anaplasmataceae incluant de potentielles nouvelles espèces. Les prévalences rapportées dans chaque étude démontrent que les animaux sont les réservoirs de ces infections. Les recherches menées sur les tiques ont permis d’identifier de potentiels vecteurs d’Anaplasmataceae dans différentes régions du monde. Les potentielles nouvelles espèces identifiées sont caractérisées en ciblant différents gènes, et les analyses moléculaires démontrent qu’elles sont différentes des autres Anaplasmataceae connues jusqu’à maintenant. Ces différents travaux apportent donc davantage d’informations sur l’épidémiologie des Anaplasmataceae dans le monde. / In this work, we are interested in studying Anaplasmataceae infections in animals and their ticks. Our objective is to describe these infections in animals and to identify new species implicated in different pathology. First, we propose a molecular diagnostic approach that couples a qPCR followed by amplification and sequencing targeting the 23S rRNA gene. Then we propose other primers targeting other genes including the ribosomal subunit beta (rpoB), heat shock protein (groEl), and the 16S rRNA. Our goal was to screen and identify the different species involved, or not involved, in pathologies of animals and identify their vectors. During this work, we had access to different blood samples and ticks from different parts of the world including metropolitan France, France overseas, Algeria, the Republic of Niger, Côte d'Ivoire, Senegal and Pakistan. Our different investigations allowed to identify different species of Anaplasmataceae including potential new species. The prevalence reported in each study demonstrates that animals are the reservoirs of these infections. So, the research conducted on ticks has identified potential vectors of Anaplasmataceae in different regions of the world. Potentially new species were identified are characterized by different targeting genes. These studies provide further information on the epidemiology of Anaplasmataceae in the world.

Freud s'était intéressé à la question de l'étiologie et les spécificités de la relation d'objet dans les psychoses dès le fondement de sa théorie. Il avait buté sur la possibilité du traitement des sujets psychotiques par la psychanalyse puisqu'ils lui paraissaient inaptes au transfert à cause d'une part de l'état anobjectal primitif de leur narcissisme et d'autre part de leur régression au stade autoérotique. Lacan, dans son retour à Freud, revient sur les spécificités de la structure et cerne la question. Il étoffe ainsi son hypothèse selon laquelle la forclusion du Nom-du-Père et la réapparition dans le réel de ce qui est forclos seraient la cause de la psychose. Ce travail de recherche est une mise en tension entre la rencontre avec trois femmes dont le diagnostic de psychose est avéré et l'approche de Freud et de Lacan des psychoses pour cerner notre question de recherche. De là, notre hypothèse sera la suivante : l'amour et le transfert ont des dimensions bien particuliers dans les névroses et dans les psychoses. Néanmoins ils restent des organisateurs de la vie du sujet pour toutes les structures psychiques. À travers l'amour, le sujet psychotique essaie de suppléer : au défaut dans la symbolisation dû à la forclusion du Nom-du-Père ; au défaut de la signification phallique ; et au défaut dans la localisation de la jouissance de l'Autre. L'amour fait symptôme dans les psychoses. Il est une des seules défenses que le sujet a contre le Réel et, constitue une tentative de guérison. / Freud has focused his research on the etiology of psychosis and the specificities of object relations in psychosis since the foundation of his theory. He has confronted with the impossibility of the treatment of the psychotic patient by his methods because they seem to be incapable of transference due to their narcissism and their regression to the autoerotic stage of the development. After Freud, Lacan questions the specificities of the psychotic structure and identifies the foreclosure of the Name of the Father, a primordial signifier, as the etiologic source of the psychosis.This thesis is a tension between case studies of three psychotic women and the approach of Freud and Lacan. Our hypothesis is: love and transference have unique dimensions in neurosis and psychosis. However they still organize the life of the subject in all the structures psyches.Through love, the psychotic subject tries to compensate structural fault. It is one of the only defenses against the Real and it is an attempt to cure. The psychotic subject can form an ego by identifying with the love object. In this case, love is articulated in three registers defined by Lacan: the real, the imaginary and the symbolic. If the psychotic slides purely to the narcissistic side, if the love is based solely on the imaginary register, the deadly side of love, Thanatos, can take over.

Mealybugs (Hemiptera: Pseudococcidae) cause severe damage to many commercial crops, including grapevine. This is largely because of their ability to transmit various grapevine viral diseases, in particular grapevine leafroll-associated viruses (GLRaVs). Grapevine leafroll is one of the most wide-spread grapevine diseases worldwide. Managing the field-spread of grapevine leafroll disease requires, amongst others, stringent mealybug control. Mealybug monitoring and control methods rely on timely and accurate identification of the species present. However, proper identification of mealybug species is problematic, time-consuming and requires an expert taxonomist. In most cases, only adult females can be reliably identified morphologically. Immature insects, males and damaged specimens cannot be assigned to species. In this study, a molecular method was developed to rapidly and accurately distinguish three mealybug species associated with grapevine, namely the vine mealybug Planococcus ficus (Signoret), the citrus mealybug Planococcus citri (Risso) and the longtailed mealybug Pseudococcus longispinus (Targioni-Tozzetti). During the development of this identification method, a number of tasks were undertaken. Firstly, rapid and reliable DNA extraction methods were tested for mealybug DNA. Two rapid extraction methods were adapted and tested, namely the direct buffer method and the spot-PCR method. These methods reliably extracted DNA even from very small or damaged individuals, and could be performed in 15-20 minutes and three hours, respectively. Secondly, mealybug mitochondrial DNA from the cytochrome c oxidase subunit 1 (CO I) gene was amplified and sequenced. It was found that DNA from the 3’-end of CO I showed minimal intraspecific variation (<1%), but sufficient interspecific variation (7-12%) to clearly delineate species. This region was then used to develop three species-specific forward primers, which were used in conjunction with a common universal reverse primer. These primers were all used in a multiplex PCR to differentially amplify DNA from each of the three species. The primers were designed such that each yielded a DNA product of different length which could be separated by electrophoresis on an agarose gel. In this manner the identity of the species could be determined. The entire identification protocol (including extraction, PCR and electrophoresis) could be completed in approximately four hours. All amplified specimens in a blind trial were correctly identified, regardless of size or condition of the specimen. The protocol is simple enough to be implemented in any molecular laboratory. This represents a considerable improvement over currently available techniques for mealybug identification, and is certain to be of great use in diagnostic identification of mealybugs in vineyards and export consignments. / Dissertation (Magister Scientiae)--University of Pretoria, 2007. / Zoology and Entomology / unrestricted
