“…White spot syndrome virus (WSSV), 3 an enveloped and double-stranded circular DNA virus, is one of the major shrimp pathogens that causes a cumulative mortality of up to 100% within a week and has consistently affected shrimp farming worldwide and led to drastic losses in shrimp production (1)(2)(3)(4). An insight into the molecular mechanisms underlying the shrimp-virus immune interactions is particularly essential for helping combat these viral infections and improving the cultured shrimp immunity.…”

Background: Melanization plays a major role in invertebrate defense. Results: Suppression of shrimp melanization increased the WSSV susceptibility. The viral protein, WSSV453, interferes the proPO system via PmPPAE2 inhibition. Conclusion: Shrimp melanization has an antiviral role. WSSV overcomes this by suppressing the host proPO proteinase cascade. Significance: The regulation of shrimp melanization during WSSV infection was first demonstrated.

“…Some examples of the system in crisis include: unsustainable water withdrawals for agriculture (UN-Water 2009;FAO 2012) the loss of land productivity following degradation from overgrazing of marginal land (Geist and Lambin 2004;Slimani et al 2010;Alemseged et al 2011;Zhou et al 2011); decreasing fish yields as the globalised trade in aquatic farming exacerbates the spread of disease from the intensive farming of aquatic livestock (Stentiford et al 2012); soil nutrient deficiency and the collective damage to the environment of processes connected with intensive mono-cropping (Watson et al 2002;Ball et al 2005;Govaerts et al 2007); and the loss of free ecosystem services, for example from bees which naturally help to pollinate crops (Kremen et al 2002;Brown and Paxton 2009). Land degradation alone is predicted to reduce global yields by 30 % in the next 20-50 years (Pimentel 2006) during which time, global demand will require yield increases of 40 % (Beddington 2010).…”

Combining micro-bottom-up and macro-top-down modelling responses to nutrient cycles in complex agricultural systems

Concerns over the long-term sustainability of the food production system and the nutritional content of food from mineral depleted soils have encouraged a policy shift to sustainable agricultural practices where soil health supports nutrition-sensitive agriculture. Interventions at the micro scale have the ability to affect the entire system, forcing an examination at the whole of systems level. Modelling plays an important role in determining the outcomes of policy intervention combinations, particularly when systems are identified as being complex. This study begins with a systems map tracing the nutrient cycling process between natural ecosystem processes and farm practices from the bottom-up within a top-down framework. Soil is at the centre of this approach, expanding links to other influences within the framework in order to understand the relationships between elements in an environmental-agricultural system. Moving to a generic model from a broad conceptual system map is problematic when crop types, plant mineral absorption rates, soil and geographic differences are to be accommodated. Work has been done to develop top-down framework models integrating bottom-up component models, capable of being used in different scenarios. Whether existing models are used or new models are created, this study recommends that an appropriate modelling response require examination of systems and policy interventions both holistically and in detail encompassing situational specifics.

White spot syndrome virus (WSSV) is the most important pathogen known to affect the sustainability and growth of the global penaeid shrimp farming industry. Although most commonly associated with penaeid shrimp farmed in warm waters, WSSV is also able to infect, cause disease in and kill a wide range of other decapod crustaceans, including lobsters, from temperate regions. In 2005, the European Union imported US$500 million worth of raw frozen or cooked frozen commodity products, much of which originated in regions positive for white spot disease (WSD). The presence of WSSV within the UK food market was verified by means of nested PCR performed on samples collected from a small-scale survey of supermarket commodity shrimp. Passage trials using inoculum derived from commodity shrimp from supermarkets and delivered by injection to specific pathogen-free Pacific white shrimp Litopenaeus vannamei led to rapid mortality and pathognomonic signs of WSD in the shrimp, demonstrating that WSSV present within commodity shrimp was viable. We exposed a representative European decapod crustacean, the European lobster Homarus gammarus, to a single feeding of WSSV-positive, supermarket-derived commodity shrimp, and to positive control material (L. vannamei infected with a high dose of WSSV). These trials demonstrated that lobsters fed positive control (high dose) frozen raw products succumbed to WSD and displayed pathognomonic signs associated with the disease as determined by means of histology and transmission electron microscopy. Lobsters fed WSSV-positive, supermarket-derived commodity shrimp (low dose) did not succumb to WSD (no mortality or pathognomonic signs of WSD) but demonstrated a low level or latent infection via PCR. This study confirms susceptibility of H. gammarus to WSSV via single feedings of previously frozen raw shrimp products obtained directly from supermarkets.
