Texte intégralMetazoans colonizing deep-sea reducing habitats often employ chemosymbiotic bacterial associations. Hosts become dependent upon their sulfur-oxidizing and/or methanotrophic symbionts, which provide organic carbon compounds. Various larval dispersal strategies have evolved in the hosts, ensuring the colonization of new sites. The continuity of the symbiotic association is maintained by symbiont transmission. Symbionts may pass directly to the host’s progeny via gametes (vertical transmission) or may be acquired from the environment as free-living forms or as those released from other hosts (horizontal transmission). This work answers several questions about the lifecycles of symbionts regarding the diversity of symbiont-related bacteria in environmental bacterial communities; the localization and dynamics of symbionts in host tissues depending on their transmission mode; or after abiotic stresses applied to the holobiont.The diversity and the distribution of free-living symbionts and their close relatives from several chemosynthesis-based habitats has been analysed by 454 pyrosequencing of the 16S rRNA of bacteria colonizing plant-derived substrates in the Northern Atlantic and Mediterranean. The trans-ovarial transmission has been detailed in the clam Isorropodon bigoti by the identification of symbionts within oocytes and in the forming gills of their post-larvae. Finally, the influence of several abiotic stresses in Bathymodiolus azoricus mussels on the dynamics of their symbionts has been investigated by FISH and pyrosequencing. This PhD presents new data regarding various aspects of the life cycle of chemosynthetic symbionts inside and outside their metazoan hosts

Texte intégralMany animals including humans live in symbiotic interaction with gut microorganisms contributing to essential functions (nutrition, immunity). The ‘vertical’ way of transmission of symbionts (i.e., from parents to offspring) must stabilise these symbioses, notably by strengthening partner fidelity. However, the efficiency of vertical transmission has rarely been studied, especially in the case where hosts harbour a complex microbial community (or ‘microbiota’) composed by many microbial taxa interacting between them and with the host.The objective of this work was to study the mode and efficiency of transmission of gut microorganisms (protists and bacteria) helping the wood-feeding termite Reticulitermes grassei to digest ingested wood (lignocellulose fibres). Our results revealed contrasted situations between microorganisms. While protists are efficiently vertically transmitted, the majority of bacterial taxa is not only vertically transmitted but seems to be acquired by the environment

Texte intégralIn Mammals microbial recruitment starts in utero, something that had not been shown in any other Vertebrate class. The main goal of this project was to test whether this type of recruitment happens in a non-mammalian Vertebrate. We tested in the viviparous fish Brachyistius frenatus the hypothesis under which the uterine pouch is colonized by a microbiome transmissible to the juveniles, conferring them an ontogeny similar to Mammals. This project also aimed to i) characterize the mode of transmission of the microbiota, ii) establish the composition, diversity and relationships between the microbial communities of pregnant females, juveniles and their environment and iii) determine the ontogeny of the microbiota in B. frenatus. We characterized the mode of transmission of the microbiome, explored its recruitment and the contribution of different source communities with a metagenomic approach (bar coding). We targeted the hyper variable region V4 of the small subunit (16S) rRNA gene to determine the presence of a vertical transmission of the microbiome In this study, we confirmed the presence of a vertically transmissible microbiome in the viviparous fish B. frenatus. We documented for the first time an in utero transmission of themicrobiota in a non-mammalian viviparous species. Our results also hint that B. frenatus might be a new model of microbiota ontogeny. This study contributes to the acquisition of knowledge on microbiome transmission and, in the context of evolutionary convergence of viviparity, allows the formulation of hypotheses concerning the evolutionary advantages of in utero microbiome transmission.

Texte intégralEsta dissertação teve como objetivo principal caracterizar a fauna de simbiontes de chimpanzés (Pan troglodytes), e colobos pretos e brancos (Colobus sp.) de diferentes localidades Africanas (Parque Nacional de Sapo, na Libéria e em Bulindi, no Uganda), comparar resultados entre eles e estudos prévios e teorizar sobre as possíveis implicações zoonóticas dos simbiontes encontrados. Recorrendo a técnicas de coprologia como sedimentação MIF modificada e a flutuação de Sheather, e um teste de imunofluorescência direta para deteção de oocistos de Crypstosporidium e cistos de Giardia, 47 amostras fecais preservadas de chimpanzé e 15 de colobos pretos e brancos foram examinadas. Os protozoários detetados incluíram Troglodytella abrassarti, Entamoeba spp., Blastocystis sp. e Iodamoeba buetschlii; e nematodes, Trichuris sp, Colobenterobius sp., strongylideos e várias larvas de nematodes. Todas as amostras foram negativas no teste de imunofluorescência directa. Em geral, o espectro de simbiontes encontrado no presente estudo está de acordo com o que é regularmente descrito em estudos que abordam chimpanzés e colobos pretos e brancos de vida selvagem. Contudo, pequenos microrganismos aquáticos denominados Rotifera ou rotíferos foram observados pela primeira vez em amostras fecais de chimpanzé e colobos pretos e brancos. Considerando o contato próximo entre os primatas estudados e seres humanos, é importante realizar futuras pesquisas recorrendo a técnicas moleculares nos simbiontes assinalados por este trabalho e avaliar o seu real potencial zoonótico.
ABSTRACT - Gastrointestinal symbionts of wild chimpanzees and sympatric colobus monkeys living in close proximity of humans in Liberia and Uganda - This dissertation aimed to characterize the symbiont fauna of chimpanzees (Pan troglodytes) and black and white colobus (Colobus sp.) from different African localities, (Sapo National Park in Liberia and Bulindi in Uganda), compare results between them and previous studies, and theorize about possible zoonotic implications of the found symbionts. Using coprologic techniques as modified MIF sedimentation and Sheather’s flotation, and a direct immunofluorescence teste for detection of Crypstosporidium oocysts and Giardia cysts, 47 chimpanzee and 15 black and white colobus preserved fecal samples were examined. Detected protozoans included Troglodytella abrassarti, Entamoeba spp., Blastocystis sp. and Iodamoeba buetschlii; and nematodes, Trichuris sp., Colobenterobius sp., strongylids and various nematodes larvae. All samples were negative for the direct immunofluorescence test. Overall, the spectrum of symbionts found in the present study is in accordance with what is regularly described in studies addressing the free ranging chimpanzees and black and white colobus. However, small aquatic microorganisms denominated Rotifera or rotifers were observed for the first time in chimpanzee and in black and white colobus faecal samples. Considering the close contact between the studied primates and humans, it is important to conduct further research using molecular techniques in the found symbionts to assess the real zoonotic potential.

Zug, Roman. « The Wolbachia pandemic among arthropods : interspecies transmission and mutualistic effects ». Doctoral thesis, Humboldt-Universität zu Berlin, 2018. http://dx.doi.org/10.18452/18866.
Texte intégralWolbachia are widespread bacterial symbionts of arthropods. They are transmitted predominantly via maternal inheritance, but are also able to move between different species (horizontal transmission). Wolbachia are notorious for selfishly interfering with host reproduction, but they can also evolve mutualistic associations with their hosts. In this thesis, we analyze the role of horizontal transmission and mutualistic effects in the Wolbachia pandemic among arthropods. First, we derive an estimate of the number of Wolbachia-infected arthropod species and find that millions of species are infected. In order to explain this striking distribution, we develop a model of Wolbachia horizontal transmission between species, building on epidemiological theory and network theory. Our findings point to the importance of transmission over large phylogenetic distances. Given that successful horizontal transmission is likely to be facilitated by symbiont-induced host benefits, we then perform a comprehensive review of Wolbachia-arthropod mutualisms and find that these occur in diverse contexts, although the evidence of Wolbachia-induced host protection in nature is limited so far. By means of a population genetic model, we then analyze the influence of host benefits on the infection dynamics of Wolbachia. For the first time, we derive invasion conditions and equilibrium frequencies for Wolbachia double infections. Our results corroborate that host benefits substantially facilitate invasion of Wolbachia into novel hosts. Finally, we examine the interactions between Wolbachia infection and the host immune system, with a focus on reactive oxygen species. We propose a hypothesis that explains differential immune responses in novel and coevolved associations. Taken together, the findings presented in this thesis argue for a significant involvement of horizontal transmission and mutualistic effects in the Wolbachia pandemic among arthropods.
