Résumé :

Exotic species have had devastating impacts worldwide and are a major threat to native wildlife. Human commensal species (hereafter commensals) are a special class of exotic species that live largely off the resources associated with human activity. The encroachment of commensals from an urban area into surrounding bushland has been frequently overlooked as an important component of urban impacts, even though human-commensals are common to many urban regions globally. In this review, we present theoretical and empirical evidence for the processes and outcomes occurring when exotic commensal sp

Résumé :

Pathogenic Neisseria gonorrhoeae causes the sexually transmitted infection gonorrhea. N. gonorrhoeae has evolved high levels of antimicrobial resistance (AR) leading to therapeutic failures even in dual-therapy treatment with azithromycin and ceftriaxone. AR mechanisms can be acquired by genetic transfer from closely related species, such as naturally competent commensal Neisseria species. At present, little is known about the antimicrobial resistance profiles of commensal Neisseria. Here, we characterized the phenotypic resistance profile of four commensal Neisseria species (N. lactamica, N.

Résumé :

Symbionts dominate planetary diversity and three primary symbiont diversification processes have been proposed: co-speciation with hosts, speciation by host-switching, and within-host speciation. The last mechanism is prevalent among members of an extraordinary marine symbiosis in the Indian River Lagoon, Florida, composed of a host mantis shrimp, Lysiosquilla scabricauda, and seven host-specific commensal vasconielline “yoyo” clams (Galeommatoidea) that collectively occupy two distinct niches: burrow-wall-attached, and host-attached/ectocommensal.

Résumé :

The immunological impact of individual commensal species within the microbiota is poorly understood limiting the use of commensals to treat disease. Here, we systematically profile the immunological fingerprint of commensals from the major phyla in the human intestine (Actinobacteria, Bacteroidetes, Firmicutes and Proteobacteria) to reveal taxonomic patterns in immune activation and use this information to rationally design commensal communities to enhance antibacterial defenses and combat intestinal inflammation.

AbstractRoots of different plant species are colonized by bacterial communities, that are distinct even when hosts share the same habitat.

Commensalism within anthropogenic environments has not been extensively discussed, despite its impact on humans, and there is no formal framework for assessing this ecological relationship in its varied forms. Here, we examine commensalism in anthropogenic environments in detail, considering both ecological and evolutionary drivers. The many assumptions about commensalism and the nature of anthropogenic environments are discussed and we highlight dependency as a key attribute of anthropogenic commensals (anthrodependent taxa).

Abstract Human Ro60 is an RNA binding protein that is commonly targeted in systemic autoimmunity. We identified Ro60 orthologs that are conserved in a subset of skin, oral, and gut commensal species. Since anti-Ro60 antibodies are the earliest autoantibodies detected in lupus patients, we hypothesized that commensal Ro60 orthologs may trigger autoimmunity via autoepitope cross-reactivity in genetically susceptible individuals. While Ro60-producing gut commensals were common among both healthy controls and lupus patients, only antibodies from 4 Ro60-positive lupus patients, but not Ro60-negativ

While the structure and regulatory networks that govern type-six secretion system (T6SS) activity of Vibrio cholerae are becoming increasingly clear, we know less about the role of T6SS in disease. Under laboratory conditions, V. cholerae uses T6SS to outcompete many Gram-negative species, including other V. cholerae strains and human commensal bacteria. However, the role of these interactions has not been resolved in an in vivo setting. We used the Drosophila melanogaster model of cholera to define the contribution of T6SS to V. cholerae pathogenesis. Here, we demonstrate that interactions be

Abstract Background Pathogenic CD4+ T-cell responses to commensal microbial antigens drive intestinal inflammation in Crohn’s disease (CD). Both hypo- or hyperactive anti-microbial innate immunity could underlie these aberrant T-cell responses. CD patients have increased IgG and T cell responses against commensal Lachnospiraceae-derived flagellins, which associate with disease complications. We investigated whether CD patients with high anti-Lachnospiraceae flagellin responses at diagnosis have underlying innate hypo- or hyperresponsiveness and high IgG responses to other dysbiotic commensals.

Neisseria gonorrhoeae, the etiological agent of gonorrhea, infects over 62 million people annually worldwide. Many of these infections occur asymptomatically, demonstrating that N. gonorrhoeae can infect mucosal epithelia without causing overt disease. The Neisseria genus also contains over eight commensal species, which by definition, are capable of colonizing host cells without causing disease. These findings indicate that Neisseria species have developed strategies for minimizing the host immune response to infection. To investigate these strategies we infected endocervical and nasopharynge

Extensive use of the sulphonamide drugs against the bacterium Neisseria meningitidis has resulted in drug resistance development.

One type of resistant DHPS has high sequence divergence compared to DHPS from susceptible strains. This divergent DHPS has a duplication of two amino acids, crucial for resistance, and an altered amino acid in position 68, important for both resistance and substrate binding.

This species differs from others in the genus in having a one-articulate first maxilla palp and an apically produced tuberculate lobe on the inner margin of the outer plate of the maxilliped.

Therefore, I wondered whether B cells may also be affected in this manner. Herein, I examine primary human B cell responses to infection wit

This chapter presents overviews of a broad selection of the domesticated forms of mammals and birds and their wild counterparts.

Texte intégral

Résumé :

Fungal plant pathogens are responsible for extensive annual crop and revenue losses throughout the world. To better understand why fungi cause diseases, we performed gene-disruption mutagenesis on several pathogenic Colletotrichum species and demonstrated that pathogenic isolates can be converted to symbionts expressing non-pathogenic lifestyles. One group of nonpathogenic mutants confer disease protection against pathogenic species of Col!etotrichum, Fusarium and Phytophthora; drought tolerance; and growth enhancement to host plants. These mutants have been defined as mutualists and disease r

Résumé :

Camera trapping is increasingly used to collect information on wildlife occurrence and behaviour remotely. This provides insights into habitat use by species of interest and gathers information on non-target species. We implemented ground-based camera trapping to investigate behaviours of ground-dwelling birds and to monitor activities of Agassiz’s desert tortoises at their self-constructed burrows in a wind-energy facility near Palm Springs, California. While doing so, we collected data on numerous burrow commensals, including birds. Monitoring from late spring to midautumn showed regular use

Résumé :

Mastitis, an inflammatory response of the mammary tissue to invading pathogenic bacteria, is the largest health problem in the dairy industry and is responsible for multibillion dollar economic losses. E. coli are a leading cause of acute mastitis in dairy animals worldwide and certainly in Israel and North America. The species E. coli comprises a highly heterogeneous group of pathogens, some of which are commensal residents of the gut, infecting the mammary gland after contamination of the teat skin from the environment. As compared to other gut microflora, mammary pathogenic E. coli (MPEC) m

Résumé :

Fungal plant pathogens are responsible for extensive annual crop and revenue losses throughout the world. To better understand why fungi cause diseases, we performed gene-disruption mutagenesis on several pathogenic Colletotrichum species and demonstrated that pathogenic isolates can be converted to symbionts (mutualism, commensalism, parasitism) expressing non-pathogenic lifestyles. The objectives of this proposal were to: 1- generate crop-specific mutants by gene disruption that express mutualistic lifestyles, 2- assess the ability of the mutualists to confer disease resistance, drought tole
