TL;DR: The shrimp farming industry of the Americas has responded to the challenges posed by disease and it has developed methods to manage its diseases and mature into a sustainable industry.

TL;DR: The current choices and trends of large-scale production and purification of VLP-based vaccines generated through the baculovirus expression vector system using insect cells are reviewed.

TL;DR: It was shown that emerging moths were infected with nematodes, which may aid in control and dispersal, and the first report on the potential use of EPN to control the soil-borne life stages of FCM, which includes larvae, pupae and emerging moth.

TL;DR: Adaptations that have been made over the last 10 years to improve the baculovirus-insect cell expression system are described, including enhanced trafficking, folding and glycosylation of the recombinant protein as well as preventing intracellular degradation.

TL;DR: A systematic review of parasites, pathogens and commensals of freshwater crayfish has been conducted covering all major groups of disease causing agents including viruses, bacteria, fungi, protistans and metazoans.

TL;DR: Some bacteria pathogens occur commonly in blue crab haemolymph and should be paid much attention to because they may represent potential health hazards to human beings because they can cause serious diseases when the crab is consumed as raw sea food.

TL;DR: A combination of physiological parameters is desirable in the assessment of stress response or health status in crustacean species transported live to seafood markets, as well as investigating the influence of stress responses on health and survival during live transport.

TL;DR: Analysis of the impact of N. ceranae on queen physiology found that infection by this microsporidian parasite did not affect the fat body content but did alter the vitellogenin titer, the total antioxidant capacity and the queen mandibular pheromones, which surprisingly were all significantly increased in Nosema-infected queens.

TL;DR: RPW hemocytes, the main immunocompetent cells in the insect, are described for the first time and the hemocyte response of RPW larvae to sub-lethal doses of commercial products containing Bt was examined.

TL;DR: The authors' studies indicate that N. ceranae is the dominant species in Virginia with an estimated 69.3% of hives infected, and traditional diagnoses based on spore counts alone do not provide an accurate indication of colony infections.

TL;DR: The midgut histopathology of Vip3Aa fed larvae showed vacuolization of the cytoplasm, brush border membrane destruction, vesicle formation in the apical region and cellular disintegration, which supports the use of VIP3AA16 proteins as insecticidal agent, especially in case of Cry-resistance management.

TL;DR: The giant freshwater prawn Macrobrachium rosenbergii is cultivated essentially in Southern and South-eastern Asian countries such as continental China, India, Thailand and Taiwan and is the origin of so-called white tail disease (WTD), responsible for mass mortalities and important economic losses in hatcheries and farms for over a decade.

TL;DR: The baculovirus-insect cell system could be used for the expedited production of a safe and efficacious influenza vaccine and should provide a fast track worldwide solution for newly emerging influenza strains or pandemic preparedness within a few years.

TL;DR: It is suggested that certain species of Metarhizium and Beauveria are significantly associated with the strawberry, blueberry and Christmas tree rhizosphere and could potentially provide better control of O. sulcatus.

TL;DR: It is confirmed that this species carries a novel A. astaci genotype, and improving knowledge on the diversity of this parasite may facilitate identification of genotypes in mass mortalities of European crayfish, thus tracing the sources of infection.

TL;DR: Fungal and bacterial pathogens present significant threats for rearing spiny lobsters in aquaculture settings, but only one pathogen, Panulirus argus virus 1, is thought to have damaged a fishery for a spiny lobster.

TL;DR: The European house cricket, Acheta domesticus L., is highly susceptible to A. domesticus densovirus (AdDNV), and facilities that are producing disease-free crickets have avoided the importation of crickets and other non-cricket species.

TL;DR: In this paper, the authors performed a longitudinal cohort study over 6 years by closely monitoring 220 honey bee colonies kept in 22 apiaries (ten randomly selected colonies per apiary). Observed winter colony losses varied between 4.8% and 22.4%.

TL;DR: This study expands significantly on what the authors know about the variation of heliothine NPV populations, provides novel information on the distinct groups in which these NPVs occur, and contributes to the knowledge required for improvement of heluothine baculoviruses as biological control agents.

TL;DR: This review reports data on several important viral diseases of crabs, particularly those associated with pathology of organs and tissues of commercially and ecologically significant host species.

TL;DR: Results demonstrate that the step of activation, mainly, is at the origin of the difference of susceptibility of these two larvae towards B. thuringiensis Vip3Aa16 toxin.

TL;DR: This is the first systematic examination of the physiological basis for the low efficacy of Cry toxins against aphids, and analysis of Cry toxin-aphid gut interaction.

TL;DR: A histological examination of 69 samples of Acropora sp. manifesting different types of tissue loss (Acropora White Syndrome-AWS) from Hawaii, Johnston Atoll and American Samoa between 2002 and 2006 was performed and classified as diffuse acute, diffuse sub-acute, and focal to multifocal acute to subacute.

TL;DR: Data suggest that although activated Vip3Aa10 specifically interacts with BBMV of H. armigera and forms an ion channel, the mode of action of it may be different from that of Cry1A toxins.

TL;DR: Current knowledge is attempted to summarize current knowledge on several crab diseases, their protistan etiological agents, the impact of disease on economically important crab populations and draw attention to areas of needed research.

TL;DR: The baculovirus-insect cell expression system is a well-established technology for the production of heterologous viral (glyco)proteins in cultured cells, applicable for basic scientific research as well as for the development and production of vaccines and diagnostics.

TL;DR: Shrimp treated with a single administration of vp28 or vp26 dsRNA and consecutively challenged with WSSV showed a stronger and longer antiviral response than shrimp exposed once to WSSv at 10 or 20dpt.

TL;DR: These studies show selectively enhanced cellular defences of shrimp following 'vaccination', which was significantly enhanced for bacteria-exposed shrimp at 10 days post-challenge.

TL;DR: Molecular tools to detect and quantify two bacteria phoretically associated with entomopathogenic nematodes (EPNs) in the families Heterorhabditidae and Steinernematodae and extend the repertoire of species specific primers and TaqMan® probes for EPNs to include widely distributed species used commercially for biological control.

TL;DR: This review presents the principles and achievements of the Sf9/baculovirus system for the production of AAV in comparison to other expression systems based on mammalian cells and recommends further process intensifications for clinical doses for the treatment of neuromuscular diseases.
