A systematic approach toward progressive improvement of national antimicrobial resistance surveillance systems in food and agriculture sectors.

The first Food and Agriculture Organization of the United Nations (FAO) Action Plan on antimicrobial resistance (AMR), published in 2016, identified the need to develop capacity for AMR surveillance and monitoring in food and agriculture sectors. As part of this effort, FAO has developed the "Assessment Tool for Laboratories and AMR Surveillance Systems" (FAO-ATLASS) to assist countries in systematically assessing their AMR surveillance system in food and agriculture. FAO-ATLASS includes two different modules for surveillance and laboratory assessment.

Comparison of the sensitivity, specificity, correlation and inter-assay agreement of eight diagnostic in vitro assays for the detection of African swine fever virus.

With the recent spread of African swine fever (ASF) in Europe, Asia and the Caribbean region, after being endemic for decades in Africa, PCR-based commercial kits and various master mixes are increasingly being used in addition to the Office International des Epizooties-recommended protocol from King et al. (World Organization for Animal Health). Often, the availability and cost of commercial kits or master mixes can be a limiting factor for diagnostic laboratories, in addition to the requirements for transportation and storage of temperature-sensitive reagents in remote areas.

Dog rabies control in West and Central Africa: A review.

Rabies is a neglected but preventable zoonotic disease that predominantly affects the most vulnerable populations living in remote rural areas of resource-limited countries. To date, every country on the African mainland is considered endemic for dog-mediated rabies with an estimated 21'500 human rabies deaths occurring each year. In 2018, the United Against Rabies collaboration launched the Global Strategic Plan to end human deaths from dog-mediated rabies by 2030.

A Tool for Assessment of Animal Health Laboratory Safety and Biosecurity: The Safety Module of the Food and Agriculture Organization's Laboratory Mapping Tool.

The Laboratory Management Tool (LMT) is a standardized spreadsheet-based assessment tool developed to help support national, regional, and global efforts to maintain an effective network of animal health and veterinary public health laboratories. The safety and biosecurity module of the LMT (LMT-S) includes 98 measures covering administrative, operational, engineering, and personal protective equipment practices used to provide laboratory safety and biosecurity. Performance aspects of laboratory infrastructure and technical compliance considered fundamental for ensuring that a laboratory is able to appropriately function in a safe and biosecure manner are systematically queried and scored for compliance on a four-point scale providing for a semi-quantitative assessment.

FAO/INFOODS food composition database for biodiversity.

Nutrient content can vary as much between different varieties of the same foods, as they do among different foods. Knowledge of varietal differences can therefore mean the difference between nutrient adequacy and inadequacy. The FAO/INFOODS food composition database for biodiversity has been developed with analytical data for foods described at the level of variety, cultivar and breed, and for underutilized and wild foods.

Enterocyte metabolism during early adaptation after extensive intestinal resection in a rat model.

Objective: A better knowledge of intestinal adaptation after resection is required to improve the nutritional support that is given to patients. The aim of this study was to understand the metabolic changes underlying early adaptation after massive intestinal resection.

Methods: Rats were assigned to either 80% intestinal resection or transection.

Adaptative increase of ornithine production and decrease of ammonia metabolism in rat colonocytes after hyperproteic diet ingestion.

Chronic high-protein consumption leads to increased concentrations of NH(4)(+)/NH(3) in the colon lumen. We asked whether this increase has consequences on colonic epithelial cell metabolism. Rats were fed isocaloric diets containing 20 (P20) or 58% (P58) casein as the protein source for 7 days.

Inhibition of human colon carcinoma cell growth by ammonia: a non-cytotoxic process associated with polyamine synthesis reduction.

Ammonia, produced by bacterial degradation of unabsorbed and endogenous nitrogenous compounds, is found to be present at millimolar concentrations in the colon lumen. From in vivo animal experiments, this metabolite has been shown to alter colonic epithelial cell morphology and to increase compensatory cell proliferation when present in excess. In this in vitro study, using the human colon adenocarcinoma HT-29 Glc(-/+) cell line treated with increasing doses of NH(4)Cl, we found that 20 mM NH(4)Cl, a concentration close to that found in the large intestine lumen, was able to increase the volume of vacuolar lysosomes and to repress HT-29 Glc(-/+) cell proliferation.
