The relationship between the presence of antibodies and direct detection of Toxoplasma gondii in slaughtered calves and cattle in four European countries
Opsteegh, M. ; Spano, F. ; Aubert, D. ; Balea, A. ; Burrells, A. ; Cherchi, S. ; Cornelissen, J.B.W.J. ; Dam-Deisz, C. ; Guitian, J. ; Györke, A. ; Innes, E.A. ; Katzer, F. ; Limon, G. ; Possenti, A. ; Pozio, E. ; Schares, G. ; Villena, I. ; Wisselink, H.J. ; Giessen, J.W.B. van der - \ 2019

Cattle - Detection - Mouse bioassay - PCR - Serology - Toxoplasma gondii

In cattle, antibodies to Toxoplasma gondii infection are frequently detected, but evidence for the presence of T. gondii tissue cysts in cattle is limited. To study the concordance between the presence of anti-T. gondii IgG and viable tissue cysts of T. gondii in cattle, serum, liver and diaphragm samples of 167 veal calves and 235 adult cattle were collected in Italy, the Netherlands, Romania and the United Kingdom. Serum samples were tested for anti-T. gondii IgG by the modified agglutination test and p30 immunoblot. Samples from liver were analyzed by mouse bioassay and PCR after trypsin digestion. In addition, all diaphragms of cattle that had tested T. gondii-positive (either in bioassay, by PCR on trypsin-digested liver or serologically by MAT) and a selection of diaphragms from cattle that had tested negative were analyzed by magnetic capture quantitative PCR (MC-PCR). Overall, 13 animals were considered positive by a direct detection method: seven out of 151 (4.6%) by MC-PCR and six out of 385 (1.6%) by bioassay, indicating the presence of viable parasites. As cattle that tested positive in the bioassay tested negative by MC-PCR and vice-versa, these results demonstrate a lack of concordance between the presence of viable parasites in liver and the detection of T. gondii DNA in diaphragm. In addition, the probability to detect T. gondii parasites or DNA in seropositive and seronegative cattle was comparable, demonstrating that serological testing by MAT or p30 immunoblot does not provide information about the presence of T. gondii parasites or DNA in cattle and therefore is not a reliable indicator of the risk for consumers.

Gamification - Serious games - Stakeholder participation - Sustainability - Water governance

Most of the literature on serious games and gamification calls for a shift from evaluating practices to using theories to assess them. While the former is necessary to justify using game-based approaches, the latter enables understanding "why" game-based approaches are beneficial (or not). Based on earlier review papers and the papers in this special issue of Water entitled "Understanding game-based approaches for improving sustainable water governance: the potential of serious games to solve water problems", we show that game-based approaches in a water governance context are relatively diverse. In particular, the expected aims, targeted audience, and spatial and temporal scales are factors that differentiate game-based approaches. These factors also strongly influence the design of game-based approaches and the research developed to assess them. We developed a framework to guide and reflect on the design and assessment of game-based approaches, and we suggest opportunities for future research. In particular, we highlight the lack of game-based approaches that can support "society-driven" sustainable water governance.

Humus - Humus classification - Humus forms - Humus systems - Humusica - Terrestrial humus forms
This article is an as simple as possible key of classification of terrestrial (aerobic, not submersed) topsoils (organic and organic-mineral series of soil horizons). Based on the introduction exposed in Humusica 1, article 1, and using vocabulary and definitions listed in article 4, a classification is proposed for better understanding the biological functioning of the soil, partially disclosing the process of litter digestion. Five types of terrestrial topsoils, called terrestrial humus systems, are described and illustrated with the help of photographs. Within each humus system, 3–4 humus forms are also revealed, corresponding to similar series of soil horizons generated in a relatively homogeneous environment whose range of ecological factors is not so large to overstep and cause the genesis of another different humus system. The article ends with a figure that shows the relationship between Tangel and Amphi humus systems, and a dichotomous key of classification that one can easily print and bring in the field for practicing humus classification.
Humusica 2, article 17 : techno humus systems and global change − three crucial questions

Some soil scientists or biologists (14, one preferring anonymity) answered the three following questions: (1. Introduction) 2. Why is organic food better (tastes better, is healthier, richer in nutrients, contains less pesticide, etc.) than food produced with hydroponic or intensive farming techniques? 3. In a humipedon, are soil functioning, biodiversity and carbon content three interdependent and intersected aspects of a single ecosystem? In other words, can we treat these aspects as if they were inseparable in a humipedon? 4. Are agriculture and civilization (the society, culture, and way of life) interconnected? All scientists expressed affirmative answers. Nuances or in depth information were also furnished. The article allows to understand the real “agronomic challenge” that the predicted Global Change might represent for humanity.

Humic component - Humipedon - Humus - Humus classification - Humus diagnostic horizon - Humusica - Recognizable remains - Terrestrial humus - Zoogenically transformed material
Knowledge of a little number of specific terms is necessary to investigate and describe humipedons. This "new vocabulary" allows individuating and circumscribing particular diagnostic horizons, which are the fundamental bricks of the humipedon. Few "components" defined by specific terms characterize a specific "humipedon horizon"; few "humipedon horizons" compose a given "humus form" and some similar "humus forms" are grouped in a functional "humus system". In this article, specific terms and humus horizons are listed and explained one by one. Field difficulties are illustrated and resolved. The aim of the article is to present in a manner as simple as possible how to distinguish in the field the soil structures allowing a morpho-functional classification of terrestrial (aerated, not submerged) humipedons.

Inactivation of Arabidopsis WAT1 (Walls Are Thin1), a gene required for secondary cell-wall deposition, conferred broad-spectrum resistance to vascular pathogens, including the bacteria Ralstonia solanacearum and Xanthomonas campestris pv. campestris, and the fungi Verticillium dahliae and Verticillium albo-atrum. Introduction of NahG, the bacterial salicylic acid (SA)-degrading salicylate hydroxylase gene, into the wat1 mutant restored full susceptibility to both R. solanacearum and X. campestris pv. campestris. Moreover, SA content was constitutively higher in wat1 roots, further supporting a role for SA in wat1-mediated resistance to vascular pathogens. By combining transcriptomic and metabolomic data, we demonstrated a general repression of indole metabolism in wat1-1 roots as shown by constitutive down-regulation of several genes encoding proteins of the indole glucosinolate biosynthetic pathway and reduced amounts of tryptophan (Trp), indole-3-acetic acid and neoglucobrassicin, the major form of indole glucosinolate in roots. Furthermore, the susceptibility of the wat1 mutant to R. solanacearum was partially restored when crossed with either the trp5 mutant, an over-accumulator of Trp, or Pro35S:AFB1-myc, in which indole-3-acetic acid signaling is constitutively activated. Our original hypothesis placed cell-wall modifications at the heart of the wat1 resistance phenotype. However, the results presented here suggest a mechanism involving root-localized metabolic channeling away from indole metabolites to SA as a central feature of wat1 resistance to R. solanacearum.
A multi-attribute decision method for assessing the overall sustainability of crop protection strategies: a case study based on apple production in Europe
Mouron, P. ; Aubert, U. ; Heijne, B. ; Naef, A. ; Strassemeyer, J. ; hayer, F. ; Gaillard, G. - \ 2012
In: Methods and Procedures for Building Sustainable Farming Systems : application in the European Context / Marta-Costa, A.A., Soares da Silva, E.L.D.G., Berlin, Germany : Springer Verlag - ISBN 9789400750029 - p. 123 - 137.
In this study, we investigated the elements that must be considered to obtain a clear and useful assessment of sustainability. We present a system-description tool created especially for life cycle assessment (assessment of energy use and ecotoxicity), environmental risk assessment, and full-cost calculations. Using the various results from these assessments as qualitative attributes, we designed a multi-attribute tool that allows us to integrate sustainability attributes over five levels into an overall sustainability rating. To demonstrate the transparency of this method and how it enables decision makers to deal with complexity, we use the method to assess different crop protection systems used in apple production. Although the multi-attribute decision method provided a reasonable overall assessment of the sustainability of different protection systems, the assessment could be substantially influenced by the selection of rating scales and decision rules. Therefore, the rating scales and decision rules should be carefully defined and discussed among the research teams. In our case, experts have participated from five European countries
