Helminth and ectoparasitic infections of ruminants and poultry have a huge impact on the biological efficiency of these vital food sources. Indiscriminate antiparasitic use has led to drug resistance across the globe. The main alternative to the dwindling supply of antiparasitics is vaccines. Here, in the PARAGONE project, findings from previous EU and other-funded projects on parasite vaccine development will be exploited to take a number of promising prototypes towards commercialisation. Partners from the Europe, China, Uruguay, SMEs and pharma, will directly move forward prototypes against the ruminant helminths Fasciola hepatica, Cooperia spp., Ostertagia ostertagi, Teladorsagia circumcincta and Haemonchus contortus and, the ectoparasitic mites, Psoroptes ovis (ruminants) and Dermanyssus gallinae (poultry). They will utilise novel adjuvants or delivery systems to maximise efficacy of some of the prototypes. Moreover, immunology studies will focus on pathogens that have previously proved problematic, often because they release immunosuppressive molecules that must be overcome for vaccines to work or because recombinant vaccines have failed to elicit protection observed with native prototypes. State-of-the-art technologies will be used to interrogate host/parasite interactions to define key signatures of protection that can be used to inform delivery systems that will enhance immunity, while other studies will define polymorphism in current vaccine candidates to ensure derived prototypes will be fit-for-purpose across geographic scales. Fundamental, is engagement of the scientists with pharma and other stakeholders (farmers, veterinarians, regulators) via many dissemination activities that will be used to obtain feedback on how the vaccines can be best deployed in the field. The output will be at least two prototypes to the point of uptake by pharma, government or philanthropic agencies, and a clear pathway to commercialisation for all prototypes studied.

Foot-and-mouth disease (FMD) is one of the worlds most infectious diseases of livestock and continues to pose a significant threat to endemic and free regions alike. The impact of FMD on society and international trade is high, thereby demanding stringent prevention, surveillance and control plans taken up in crisis preparedness plans. On the other hand, there is a global increased demand for animal welfare and ethical considerations necessitating a decreased reliance on eradication of animals to control FMD virus (FMDV) spread, and on the use of animals for the regulatory testing of veterinary products. The project seeks to balance these apparently contracting viewpoints by addressing specific gaps in our knowledge on all aspects of FMD control to enable implementation of enhanced animal-sparing vaccine-based control strategies tailored to the needs of free and endemic settings. Consequently, four main objectives have been identified, including (i) the improvement of the quality of existing FMD vaccines and diagnostics, (ii) the refinement and replacement of in vivo FMD vaccine quality tests, (iii) the development of new generation FMD vaccines and diagnostics by applying cutting edge technologies, and (iv) the enhancement of our knowledge on FMDV spread and transmission following the use of high-potency monovalent or multivalent vaccines. The role of wildlife (buffalo, gazelles and wild boar) in FMDV maintenance and transmission will also be investigated. The project consists of seven different, yet interlinked, work packages (WP) each addressing one of the items listed in the Work Programme topic KBBE-2008-1-3-02, and led by renowned WP leaders with years of relevant experience in the field of FMD. As such, significant progress towards the objectives of the Communitys Animal Health Strategy (2007-2013), the European Technology Platform for Global Animal Health, and the Global Roadmap for improving the Tools to Control FMD in Endemic Settings will be achieved.

MicroRNAs (miRNAs) are a class of endogenous non-coding small RNAs regulating gene expression in eukaryotes at the post-transcriptional level. The complex life cycles of parasites may require the ability to respond to environmental and developmental signals through miRNA-mediated gene expression. Over the past 17 years, thousands of miRNAs have been identified in the nematode Caenorhabditis elegans and other parasites. Here, we review the current status and potential functions of miRNAs in protozoan, helminths, and arthropods, and propose some perspectives for future studies. © 2010 Springer-Verlag.

Echinococcus species have been studied as a model to investigate parasite-host interactions. Echinococcus spp. can actively communicate dynamically with a host to facilitate infection, growth and proliferation partially via secretion of molecules, especially in terms of harmonization of host immune attacks. This review systematically outlines our current knowledge of how the Echinococcus species have evolved to adapt to their host's microenvironment. This understanding of parasite-host interplay has implications in profound appreciation of parasite plasticity and is informative in designing novel and effective tools including vaccines and drugs for the treatment of echinococcosis and other diseases. © 2013 Elsevier B.V.

Expert Review of Vaccines | Year: 2014

Foot-and-mouth disease (FMD) is a highly contagious and rapidly spreading disease of cloven-hoofed animals. In most countries, animals are immunized with inactivated whole virus vaccines to control the spread of foot-and-mouth disease virus (FMDV); however, there are safety and efficacy (especially, cell-mediated immunity) concerns. Many efforts are currently devoted to the development of effective vaccines by combining the application of protective antigens together with the search for specific and targeting adjuvants that maximizes the immunogenicity with a desired immune response. In this review, we outline previous studies performed with both traditional adjuvants as well as the most promising new generation adjuvants such as ligands for Toll-like receptors (TLRs) or different cytokines, focusing mostly on their efficacy when used with FMD vaccine, and somewhat on mechanisms by which adjuvants mediate their effects. © Informa UK, Ltd.
