Microbiology challenges and opportunities in the circular economy.

Our knowledge and understanding of micro-organisms have led to the development of safe food, clean water, novel foods, antibiotics, vaccines, healthier plants, animals and soils, and more, which feeds into the United Nations Sustainable Development Goals (UN SDGs). The circular economy can contribute to the UN SDGs and micro-organisms are central to circular nutrient cycles. The circular economy as described by the Ellen MacArthur foundation has two halves, i.e. technical and biological. On the technical side, non-biological resources enter manufacturing paths where resource efficiency, renewable energy and design extend the life of materials so that they are more easily reused and recycled. Biological resources exist on the other half of the circular economy. These are used to manufacture products such as bioplastics and paper. The conservation of nature's stocks, resource efficiency and recycling of materials are key facets of the biological half of the circular economy. Microbes play a critical role in both the biological and technical parts of the circular economy. Microbes are key to a functioning circular economy, where natural resources, including biological wastes, are converted by microbes into products of value and use for society, e.g. biogas, bioethanol, bioplastics, building block chemicals and compost for healthy soils. In more recent times, microbes have also been seen as part of the tool kit in the technical side of the circular economy, where microbial enzymes can degrade plastics and microbes can convert those monomers to value-added products.

Bibliometric mapping of microbiology research topics (2012-16): a comparison by socioeconomic development and infectious disease vulnerability values.

Amongst health-related scientific disciplines, microbiology appears to play a vital role in creating a sustainable future with respect to health, the environment and a biobased economy. Microbiology research covers a wide range of different disciplines and addresses many important global issues. This study aimed to identify topics being addressed within the last 5 years (2012-16) in the field of microbiology worldwide and to compare them in terms of three different indicators: gross domestic product, Human Development Index and Infectious Disease Vulnerability Index. The dataset of this study comprised 167 874 articles and reviews from 2012 to 2016, which were extracted from the Web of Science Medline. To identify and visualise the topics addressed during the studied period, VOSviewer was used. The construction and visualisation of the term map was done based on 5918 MESH subject headings. The methodology and procedures employed included Kruskal-Wallis test and two-sample proportion test. Overall, our study showed that the field of microbiology has focused on six different topics during 2012-16. The papers written with the collaboration of countries with low socioeconomic status and high vulnerability to infectious diseases mainly addressed topics related to the primary needs of people such as food safety, the prevention and control of infectious diseases, food and energy poverty. In contrast, papers written with the collaboration of countries with high socioeconomic development status and less vulnerability to infectious diseases mainly focused on big data, alternative methods to animal experiments.

Access, knowledge and experience with fluorodeoxyglucose positron emission tomography/computed tomography in infection management: a survey of Australia and New Zealand infectious diseases physicians and microbiologists.

BACKGROUND: Despite fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) being funded only for staging and restaging of some malignancies in Australia, there is evidence of benefit of FDG-PET/CT for infection indications such as pyrexia of unknown origin (PUO), prolonged neutropenic fever (NF) and prosthetic device infection. AIM: To evaluate the current knowledge, utilisation of and gaps in access to FDG-PET/CT for infectious indications by Australasian infectious diseases (ID) physicians and microbiologists. METHODS: An online survey was administered to ID and microbiology doctors practising in adult medicine in Australia and New Zealand through two established email networks. Using targeted questions and case-based examples, multiple themes were explored, including access to FDG-PET/CT, use and perceived benefit of FDG-PET/CT in diagnosis and monitoring of non-malignant conditions such as NF and PUO, and barriers to clinical use of FDG-PET/CT. RESULTS: A response was received from 120 participants across all states and territories. Onsite and offsite FDG-PET/CT access was 63% and 31% respectively. Eighty-six percent reported using FDG-PET/CT for one or more infection indications and all had found it clinically useful, with common indications being PUO, prosthetic device infections and use in the immunocompromised host for prolonged NF and invasive fungal infection. Thirty-eight percent reported barriers in accessing FDG-PET/CT for infection indications and 76% would utilise FDG-PET/CT more frequently if funding existed for infection indications. CONCLUSION: Access to FDG-PET/CT in Australia and New Zealand is modest and is limited by lack of reimbursement for infection indications. There is discrepancy between recognised ID indications for FDG-PET/CT and funded indications.

Impacto económico de los métodos de diagnóstico rápido en Microbiología Clínica: precio de la prueba o impacto clínico global / Economic impact of rapid diagnostic methods in Clinical Microbiology: Price of the test or overall clinical impact

La necesidad de reducir el tiempo de diagnóstico microbiológico y la irrupción de nuevas tecnologías relacionadas con la microbiología molecular y la proteómica han favorecido el desarrollo de técnicas rápidas y de realización en el lugar de asistencia al paciente (point-of-care), así como de los denominados laboratorios point-of-care, espacios que concentran la realización de ambas técnicas como respuesta, en parte, a la externalización de los laboratorios convencionales de los hospitales. Su introducción no siempre se ha acompañado de evaluaciones económicas (estudios de coste-efectividad, coste-beneficio y coste-utilidad) y suelen limitarse al precio unitario de la prueba. Este último, influido por el procedimiento de compra, no suele tener un valor de referencia regulado, como en el caso de los medicamentos. Los análisis de coste-efectividad que mayor repercusión han tenido han sido los realizados recientemente con la espectrometría de masas en el diagnóstico de la bacteriemia y el uso de antimicrobianos y pueden servir como modelo de futuros estudios económicos de las pruebas rápidas y point-of-care (AU)

The need to reduce the time it takes to establish a microbiological diagnosis and the emergence of new molecular microbiology and proteomic technologies has fuelled the development of rapid and point-of-care techniques, as well as the so-called point-of-care laboratories. These laboratories are responsible for conducting both techniques partially to response to the outsourcing of the conventional hospital laboratories. Their introduction has not always been accompanied with economic studies that address their cost-effectiveness, cost-benefit and cost-utility, but rather tend to be limited to the unit price of the test. The latter, influenced by the purchase procedure, does not usually have a regulated reference value in the same way that medicines do. The cost-effectiveness studies that have recently been conducted on mass spectrometry in the diagnosis of bacteraemia and the use of antimicrobials have had the greatest clinical impact and may act as a model for future economic studies on rapid and point-of-care tests (AU)

The chilean network of microbial culture collections: establishment and operation / Red chilena de colecciones de cultivos microbianos: establecimiento y operación

According to the data available at the World Data Center for Microorganism-WDCM from the World Federation for Culture Collection-WFCC, Chile has four registered culture collections that preserve 2777 microbial strains. At the global point of view, the culture collections in Chile are in different level of operation regarding its own infrastructure and compliancy with quality standards for preservation of strains and for services provide. The absence of funding to support the preservation of the Chilean microbial assets is a key issue for the development of the Chilean bioeconomy. Considering this, the Chilean culture collections started working together to establish the Chilean Network of Microbial Culture Collections (RCCCM, acronym in Spanish). In this note, the establishment and operation of the RCCCM is presented and discussed.

De acuerdo con los datos disponibles en el World Data Center for Microorganism-WDCM de la Federación Mundial para la Colección de Cultivos - WFCC, Chile tiene cuatro colecciones de cultivos registradas que preservan 2777 cepas microbianas. Desde el punto de vista global, las colecciones de cultivos en Chile se encuentran en diferentes niveles de operación con respecto a su propia infraestructura y cumplimiento con estándares de calidad para la preservación de las cepas y para los servicios que proporcionan. La ausencia de financiamiento para apoyar la preservación de los activos microbianos chilenos es un tema clave para el desarrollo de la bioeconomía chilena. Considerando esto, las colecciones chilenas de cultivos comenzaron a trabajar conjuntamente para establecer la Red Chilena de Colecciones de Cultivos Microbianos (RCCCM). En esta nota se presenta y discute el establecimiento y funcionamiento de la RCCCM.

Human resources needed to perform antimicrobial stewardship teams' activities in French hospitals.

OBJECTIVE: In January 2015, the French ministry of Health set up a task force on antibiotic resistance. Members of the task force's "antimicrobial stewardship" group conducted a study to evaluate the human resources needed to implement all the required activities of the multidisciplinary antimicrobial stewardship teams (AST - antibiotic/infectious disease lead supervisors, microbiologists, and pharmacists) in French healthcare facilities. METHODS: We conducted an online cross-sectional nationwide survey. The questionnaire was designed based on regulatory texts and experts' consensus. The survey took place between March and May 2015. We used the mailing list of the French Infectious Diseases Society (SPILF) to send out questionnaires. RESULTS: A total of 65 healthcare facilities completed the questionnaire. The human resources needed to implement all AST's activities were estimated at 3.6 full-time equivalent (FTE) positions/1000 acute care beds for antibiotic/infectious disease lead supervisors, at 2.5 FTE/1000 beds for pharmacists, and at 0.6 FTE/1000 beds for microbiologists. This almost amounts to a total of 2000 FTE positions for all healthcare facilities (public and private) in France and to an annual cost of 200 million euros. CONCLUSION: Dedicated and sustainable funding for AST is urgently needed to implement comprehensive and functional AST programs in all healthcare facilities.

A low-cost, hands-on module to characterize antimicrobial compounds using an interdisciplinary, biophysical approach.

We have developed a hands-on experimental module that combines biology experiments with a physics-based analytical model in order to characterize antimicrobial compounds. To understand antibiotic resistance, participants perform a disc diffusion assay to test the antimicrobial activity of different compounds and then apply a diffusion-based analytical model to gain insights into the behavior of the active antimicrobial component. In our experience, this module was robust, reproducible, and cost-effective, suggesting that it could be implemented in diverse settings such as undergraduate research, STEM (science, technology, engineering, and math) camps, school programs, and laboratory training workshops. By providing valuable interdisciplinary research experience in science outreach and education initiatives, this module addresses the paucity of structured training or education programs that integrate diverse scientific fields. Its low-cost requirements make it especially suitable for use in resource-limited settings.
