Abstract Background The Great Mekong Subregion has attained a major decline in malaria cases and fatalities over the last years, but residual transmission hotspots remain, supposedly fueled by forest workers and migrant populations. This study aimed to: (i) characterize the fine-scale mobility of forest-goers and understand links between their daily movement patterns and malaria transmission, using parasites detection via real time polymerase chain reaction (RT PCR) and the individual exposure to Anopheles bites by quantification of anti-Anopheles saliva antibodies via enzyme-linked immunosorbent assay; (ii) assess the concordance of questionnaires and Global Positioning System (GPS) data loggers for measuring mobility. Methods Two 28 day follow-ups during dry and rainy seasons, including a GPS tracking, questionnaires and health examinations, were performed on male forest goers representing the population at highest risk of infection. Their time spent in different land use categories and demographic data were analyzed in order to understand the risk factors driving malaria in the study area. Results Malaria risk varied with village forest cover and at a resolution of only a few kilometers: participants from villages outside the forest had the highest malaria prevalence compared to participants from forest fringe’s villages. The time spent in a specific environment did not modulate the risk of malaria, in particular the time spent in forest was not associated with a higher probability to detect malaria among forest-goers. The levels of antibody response to Anopheles salivary peptide among participants were significantly higher during the rainy season, in accordance with Anopheles mosquito density variation, but was not affected by sociodemographic and mobility factors. The agreement between GPS and self-reported data was only 61.9% in reporting each kind of visited environment. Conclusions In a context of residual malaria transmission which was mainly depicted by P. vivax asymptomatic infections, the implementation of questionnaires, GPS data-loggers and quantification of anti-saliva Anopheles antibodies on the high-risk group were not powerful enough to detect malaria risk factors associated with different mobility behaviours or time spent in various environments. The joint implementation of GPS trackers and questionnaires allowed to highlight the limitations of both methodologies and the benefits of using them together. New detection and follow-up strategies are still called for.

One-Health is an umbrella term that integrates the health of the environment, humans and non-human animals. This approach is applied here to elucidate the impact of non-native invasive species on aquaculture and food security. Despite inherent biases against these species, a better understanding of their characteristics allows for the identification of those of greatest concern, minimizing the risk of food shortages and infectious diseases. This review summarises the positive and negative impacts of non-native species, delineating the specific areas they may impact. Additionally, this review gives an insight to the expertise and stakeholders that would need to be included if a “One-Health” approach were to be implemented by policymakers to better control non-native species.Detailed examples illustrate the consequences of non-native species on trophic dynamics, ecosystem health, water chemistry, and human health, emphasizing the importance of managing them within a multidimensional framework. The “One-Health” approach is explained, and suggestions are made on how certain non-native species could be used to contribute to food security in low- and middle-income countries. Furthermore, recommendations are made to promote a more inclusive management strategy.

The effects of three medicinal plants in the feeds of juvenile Nile tilapia (Oreochromis niloticus) were investigated on growth, survival, immunity, and digestive histology at various inclusion levels: (A) Guiera senegalensis at 0, 1, 2, 4, and 8%; (B) Pluchea odorata at 0, 0.5, 1, 2, and 4%; (C) Piliostigma reticulatum at 0, 1, and 2%; and (D) a mixture of the three at 0, 1, and 2%. After 28 days of feeding, fish were infected with Aeromonas hydrophila for 12 days. The results showed that, except for G. senegalensis, the inclusion of the medicinal plants, alone or combined, enhanced the immune response. The diet with 4% P. odorata significantly increased plasma lysozyme and bactericidal activities without affecting feed conversion efficiency or growth. Despite improved immunity, none of the treatments enhanced post-infection survival rates. However, fish fed the 1% mixture showed healthier livers and intestines, with reduced cell swelling and normal lipid deposits, followed by the 2% mixture and the control. These results highlight the potential benefits of incorporating P. odorata and the plant mixture into the diets of Nile tilapia juveniles for enhancing their immune response against A. hydrophila.

Cette étude examine les relations entre la cacaoculture et l’émergence de la pisciculture en Côte d’Ivoire, en particulier les défis liés à l’utilisation de pesticides dans les exploitations cacaoyères. Elle s’appuie sur des enquêtes menées auprès de 45 cacaoculteurs également engagés dans la pisciculture, dans différentes régions cacaoyères. Les résultats montrent que la diversification vers la pisciculture dans les exploitations cacaoyères conduit à réduire ou à abandonner l’usage des pesticides, principalement des herbicides, en expérimentant différentes alternatives. Parmi ces dernières figurent des méthodes de lutte mécanique, l’adaptation des pratiques culturales et la mise en place de barrières écologiques. Ces différents changements sont réalisés dans un souci de préservation des revenus des cacaopisciculteurs, mais également de l’environnement au sein et autour des fermes de production. Les leviers susceptibles d’entraîner une diffusion de ces méthodes à large échelle sont discutés.

With an ever-increasing human population, food security remains a central issue for the coming years. The magnitude of the environmental impacts of food production has motivated the assessment of the environmental and health benefits of shifting diets, from meat to fish and seafood. One of the main concerns for the sustainable development of aquaculture is the emergence and spread of infectious animal diseases in a warming climate. We conducted a meta-analysis to investigate the influence of global warming on mortality due to viral infections in farmed aquatic animals. We found a positive trend between increasing temperature and increasing viral virulence, with an increase in water temperature of 1 °C resulting in an increase in mortality of 1.47–8.33% in OsHV-1 infected oysters, 2.55–6.98% in carps infected with CyHV-3 and 2.18–5.37% in fishes infected with NVVs. We suggest that global warming is going to pose a risk of viral disease outbreaks in aquaculture and could compromise global food security.

Abstract In the Greater Mekong Subregion, malaria cases have significantly decreased but little is known about the vectors or mechanisms responsible for residual malaria transmission. We analysed a total of 3920 Anopheles mosquitoes collected during the rainy and dry seasons from four ecological settings in Cambodia (villages, forested areas near villages, rubber tree plantations and forest sites). Using odor-baited traps, 81% of the total samples across all sites were collected in cow baited traps, although 67% of the samples attracted by human baited traps were collected in forest sites. Overall, 20% of collected Anopheles were active during the day, with increased day biting during the dry season. 3131 samples were identified morphologically as 14 different species, and a subset was also identified by DNA amplicon sequencing allowing determination of 29 Anopheles species. The investigation of well characterized insecticide mutations (ace-1, kdr, and rdl genes) indicated that individuals carried mutations associated with response to all the different classes of insecticides. There also appeared to be a non-random association between mosquito species and insecticide resistance with Anopheles peditaeniatus exhibiting nearly fixed mutations. Molecular screening for Plasmodium sp. presence indicated that 3.6% of collected Anopheles were positive, most for P. vivax followed by P. falciparum. These results highlight some of the key mechanisms driving residual human malaria transmission in Cambodia, and illustrate the importance of diverse collection methods, sites and seasons to avoid bias and better characterize Anopheles mosquito ecology in Southeast Asia.

Abstract Background After a marked reduction in malaria burden in Cambodia over the last decades, case numbers increased again in 2017–2018. In light of the national goal of malaria elimination by 2025, remaining pockets of high risk need to be well defined and strategies well-tailored to identify and target the persisting burden cost-effectively. This study presents species-specific prevalence estimates and risk stratification for a remote area in Cambodia. Methods A cross-sectional survey was conducted in 17 villages in the high-incidence province Mondulkiri in the dry season (December 2017 to April 2018). 4200 randomly selected participants (2–80 years old) were tested for Plasmodium infection by PCR. Risk of infection was associated with questionnaire-derived covariates and spatially stratified based on household GPS coordinates. Results The prevalence of PCR-detectable Plasmodium infection was 8.3% (349/4200) and was more than twice as high for Plasmodium vivax (6.4%, 268) than for Plasmodium falciparum (3.0%, 125, p

Global environmental changes threaten many food-producing sectors, including aquaculture. Here the authors show that countries most vulnerable to climate change will probably face the highest antimicrobial resistance in aquaculture-related bacteria, and that infected aquatic animals have higher mortality at warmer temperatures.

Global Positioning System (GPS) technology is an effective tool for quantifying individuals’ mobility patterns and can be used to understand their influence on infectious disease transmission. In Cambodia, mobility measurements have been limited to questionnaires, which are of limited efficacy in rural environments. In this study, we used GPS tracking to measure the daily mobility of Cambodian forest goers, a population at high risk of malaria, and developed a workflow adapted to local constraints to produce an optimal dataset representative of the participants’ mobility. We provide a detailed assessment of the GPS tracking and analysis of the data, and highlight the associated difficulties to facilitate the implementation of similar studies in the future.

The study aims to clarify the relationship between the active level of green marketing communication towards brand image and customer’s purchase desire, and examine brand image as a mediator between the green marketing communication, partially towards purchase desire. Green marketing communication consists of green action communication, green food communication, and green donation communication. This study is conclusive research and deployed the questionnaire method. The research population is the end customers who have done transactions at the green-concept food and beverages industry, live in Jabodetabek, and earn above the provincial minimum wage. The study provides empirical insight that active level of green marketing communication partially and significantly give a positive impact to brand image and customer's purchase desire. The study also proves that brand image significantly acts as a mediator between green marketing communication and purchase desire. As the research limitation due to the chosen population, the result may lack generalisability. Hence, researchers are encouraged to test the different propositions further. The study includes implications for practitioners in the food and beverage industry to improve their brand image and customer’s purchase desire by conducting green marketing communication actively. Currently, most practitioners are more focused on doing green marketing activities to affect business. This paper fulfills the need to study how the communication of green marketing affects brand image and customer’s purchase desire in food and beverages industry. Keywords: green marketing communication, green action communication, green food communication, green donation communication, brand image, purchase desire

This research is a research replication of Determinants of IT Usage and New Product Performance by Barczak, Sultan, and Gultink (2007), adapted using the characteristics of different respondents which are medium and large companies in Indonesia. The first purpose of the research is to identify antecedents of the use of IT tools. The second purpose is to further explore the role of IT in building innovative capabilities that generate values for the company. The study used a quantitative approach with a single cross-sectional conclusive design to test eight hypotheses through multiple regression measurements. The eight variables to be tested are divided into two major groups, namely the determinant variable (project risk, existence of a champion, autonomy, innovative climate, IT infrastructure, IT usage depth) and impact of IT usage performance (speed of product launch to market, market performance). The result of the research shows that the variables of IT usage depth, enterprise innovative climate, IT infrastructure, and project risk have a positive and influential relationship therefore determine the use of IT in NPD than other determinant variables. Meanwhile, the impact of IT usage on project performance is affected by the speed of product launch to market with a positive and significant relationship compared to market performance variable. The practicalities of this research, among others, is to provide an alternative action for managers to increase the use of IT in the process of New Product Development (NPD).

Four farmed stocks and four wild populations of Nile tilapia (Oreochromis niloticus), which was first introduced to Madagascar sixty years ago, were assayed for genetic variation at nine microsatellite loci to determine levels of genetic diversity within populations and genetic relationships between them. Allelic diversity overlapped with that found in previously sampled populations elsewhere in Africa. There was no evidence of deviations from allele frequencies expected under conditions of Hardy-Weinberg equilibrium or of inbreeding in studied populations. Three distinct clusters of genotypes provided evidence of three separate introductions (from Egypt and Mauritius in 1956, and from Japan in 2011), and the occurrence of genotypes from more than one cluster within a single population provided evidence of their mixing. There were significant differences between populations which were not from the same environment (wild or farmed) or were not geographically related. Wild populations may be a valuable resource to support further development of farmed stocks from the perspective of genetic diversity.

The fast development of aquaculture over the past decades has made it the main source of fish protein and led to its integration into the global food system. Mostly originating from inland production systems, aquaculture has emerged as strategy to decrease malnutrition in low-income countries. The Nile tilapia (Oreochromis niloticus) was introduced to Madagascar in the 1950s, and is now produced nationally at various scales. Aquaculture mostly relies on fry harvested from wild populations and grow-out in ponds for decades. It has recently been diversified by the introduction of several fast-growing strains. Little is known how local genetic diversity compares to recently introduced strains, although high and comparable levels of genetic diversity have previously been observed for both wild populations and local stocks. Our study compares DNA barcode genetic diversity among eight farms and several strains belonging to three species sampled. DNA-based lineage delimitation methods were applied and resulted in the detection of six well differentiated and highly divergent lineages. A comparison of DNA barcode records to sequences on the Barcode of Life Data System (BOLD) helped to trace the origin of several of them. Both haplotype and nucleotide diversity indices highlight high levels of mitochondrial genetic diversity, with several local strains displaying higher diversity than recently introduced strains. This allows for multiple options to maintain high levels of genetic diversity in broodstock and provides more options for selective breeding programs.

Konstipasi ditandai dengan buang air besar (BAB) kurang dari 3x dalam 1 minggu (Roberts, Miliikan, Galanko, Martin, & Sandler, 2003). Menurut dr. H Chudahman Manan, SpPD-KGEH, Ketua Pengurus Besar Perkumpulan Gastroenterologi Indonesia, angka kejadian konstipasi di Indonesia terus meningkat (PBGI, 2010). Untuk mengatasi konstipasi dapat menggunakan produk pencahar (Lamas, 2011), yang sudah menjadi obat over the counter (OTC) dan suplement sehari-hari (Dharmananda, Tanpa tahun). Berdasarkan Euromonitor, market size pencahar di Indonesia sebesar Rp 233.2 milyar tahun 2013, terus meningkat double digit dalam 5 tahun terakhir. Pada OTC, faktor pendorong sales ialah purchase intention (Huber, Dippold, & Forsthofer, 2012). Dengan diprediksinya terus bertambah jumlah penderita konstipasi dan terus meningkatnya market size dari industri pencahar, sehingga penting untuk diketahui faktor-faktor apa yang mempengaruhi purchase intention produk pencahar. Tujuan dari penelitian ini ialah untuk menganalisis pengaruh persepsi kualitas, persepsi harga, dan promosi terhadap persepsi nilai produk pencahar di Jakarta; serta pengaruh faktor persepsi nilai, kemasan, ketersediaan, dan keamanan terhadap purchase intention produk pencahar di Jakarta.
