The two core objectives of BIVALIFE are (i) to provide innovative knowledge related to pathogens infecting oysters and mussels and (ii) to develop practical approaches for the control of infectious diseases and resulting mortality outbreaks these pathogens induce. The project will address the major issue identified by the European commission (i.e. detection and management of infectious diseases in oysters and mussels) at the EU level since the increase in international and intra EU trade and exchanges of animals increases the risk of pathogen transfer and infectious disease outbreak occurrence. In this context, the specific objective of BIVALIFE are: (i) transfer and validate existing methods for detection and identification of oyster and mussel pathogens; (ii) improve the characterisation of oyster and mussel pathogens and develop innovative complementary diagnostic approaches; (iii) characterise culture sites in Europe regarding presence of oyster and mussel pathogens in relation to the presence or absence of mortality; (iv) investigate the life cycle, mechanisms allowing oyster and mussel pathogens to survive outside the host and their original source; (v) identify pathogen intrinsic virulence factors and effects on host defence mechanisms; (vi) assess the relationship between the presence of oyster and mussel pathogens and their role in observed mortality; (vii) develop methods and recommendations for pathogen control and eradication in Europe. The project will focus on three mollusc species, namely the Pacific cupped oyster Crassostrea gigas and two mussel species Mytilus edulis and M. galloprovincialis, the most important species in terms of European production. Interestingly, Pacific oysters and mussels display different levels of susceptibility to diseases. The targeted pathogens will be the virus OsHV-1, Vibrio species including V. splendidus and V. aestuarianus, as well as the parasite Marteilia refringens and the bacterium Nocardia crassostreae.

The overarching goal of VIVALDI is to increase the sustainability and competitiveness of the European shellfish industry by improving the understanding of bivalve diseases and by developing innovative solutions and tools for the prevention, control and mitigation of the major pathogens affecting the main European farmed shellfish species: Pacific oyster (Crassostrea gigas), mussels (Mytilus edulis and M. galloprovincialis), European flat oyster (Ostrea edulis), clams (Venerupis philipinarum) and scallops (Pecten maximus ). The project addresses the most harmful pathogens affecting either one or more of these shellfish species: the virus OsHV-1, Vibrio species including V. aestuarianus, V. splendidus, V. harveyi and V. tapetis, as well as the parasite Bonamia ostreae. The project is committed to provide practical solutions based on the most advanced knowledge. VIVALDI will dissect the disease mechanisms associated with pathogen virulence and pathogenesis and host immune responses, develop in vivo and in vitro models, and apply omic approaches that will help the development of diagnostic tools and drugs against pathogen targets, and breeding programmes in a collaborative effort with industrial partners. The proposal will include a global shellfish health approach, recognising that cultured bivalves are often exposed to several pathogens simultaneously, and that disease outbreaks can be due to the combined effect of two or more pathogens. The proposal will also investigate advantages and risks of the used of disease-resistant selected animals in order to improve consumer confidence and safety. VIVALDI will be both multi- and trans-disciplinary. In order to cover both basic and applied levels from molecules to farm, the proposal will integrate partners with a broad range of complementary expertises in pathology and animal health, epidemiology, immunology, molecular biology, genetics, genomics and food safety.


Some aspects of the invention may be related to an ultraviolet (UV) water disinfection system and a method of assembling such system. The system may be designed to treat, inactivate, disintegrate and/or remove at least two predetermined different types of contaminations. The system may include a chamber to carry the water containing the predetermined types of contaminations. The system may further include one or more first-type UV lamps having a first UV emission spectrum and one or more second-type UV lamps having a second UV emission spectrum different than the first spectrum. A location of the one or more first-type UV lamps and the one or more second-type UV lamps may be determined such that a combined UV impact function matches with a combined sensitivity response function of the two or more predetermined different types of contaminations in the water each having a different response function

Medium-pressure (MP) ultra violet (UV) disinfection was suggested as a pre-treatment to control biofouling in a semi-scale flow-through model water system. Water, spiked with Pseudomonas aeruginosa, nutrients, and carbon source, was flowed through the system and biofilm formation on glass, PVC, and stainless steel 316 slides was examined following 24 h runs. Following UV exposure a 99 % reduction in biovolume and average thickness of the biofilm was observed on all surfaces examined, despite clear differences in the virgin surface characteristics analyzed using contact angle, zeta potential, and atomic force microscopy (AFM). The findings support the stochastic behavior of biological systems in relation to predictions derived from conventional theories. The reduction of viable microbial counts seems to be the major mechanism in reducing the actual biofilm formation rate and the overall effect UV provides could indeed render it an effective tool in mitigating biofilm formation in water distribution systems. © 2016 Springer International Publishing Switzerland.

A storage tank in a water system, like a capacitor in an electrical circuit, is a very necessary common component. It serves the important function of a-synchronizing the supply water flow and the demand water Sow. Storage tanks arc common in industries such as the food and beverage, and the aquaculture industry, which both use large amounts of water. Heavy use of storage tanks is also a trademark of the pharmaceutical industry. In many water systems, the waters in a storage-tank don't just "sit" there. Rather, they are circulated. The circulation loop enables further water treatments, and in the context of the present report, serves the purpose of reducing the water's microbial load and reducing the concentratjon of water-borne chemicals. For both microbial load reduction and chemical load concentration reduction, UV light is commonly used. Thus, a theory ending with quantitative tools for the design and operation of microbial and/ or chemical loads reduction in storage-tanks- recirculation-loop configurations is of great practical importance.
