The Governance of Animal Care and Use for Scientific Purposes in Africa and the Middle East

Animals are commonly used for scientific purposes in Africa and the Middle East. However, this field is often inadequately regulated, with many countries lacking national legislation, policies, or guidelines for the care and use of animals used for research, testing, or education. This results in an essentially uncontrolled system where scientific quality and animal wellbeing cannot robustly be guaranteed, which may hinder acceptance (i.e., publication) of results by the scientific community and limit public confidence. Though accepted international guidelines and best practice recommendations exist that could be adopted or adapted to meet local needs, the responsible conduct of research and animal welfare may not be prioritized in regions that are affected by instability, poverty, disease, or malnutrition. Some notable exceptions do, however, exist in individual countries or institutions where ethical review processes, oversight of animal health and welfare, the competence of personnel, and other scientific standards are appropriately regulated and implemented. These countries and institutions represent nodes of expertise that could act as platforms of support for surrounding regions in terms of the provision of education, training, and sharing of experience and resources. To make such regional capacitystrengthening efforts sustainable will require regional cooperation, the establishment of regional networks, harmonization of policies, pooled resources, and long-term investment in education, training, and infrastructure. An overarching system is needed to oversee the efficient promotion of scientific and ethical standards and the dissemination of information on laboratory animal science in Africa and the Middle East, while each country should remain able to maintain a system of oversight that reflects its own cultures, traditions, religions, laws, and regulations. This article provides an overview of the governance of the care and use of animals for scientific purposes in different regions of Africa and the Middle East as a foundation for coordinated future advancement.</p

Partial replacement of dietary (n-6) fatty acids with medium-chain triglycerides decreases the incidence of spontaneous colitis in interleukin-10-deficient mice

Enteral nutrition has a primary therapeutic effect in active Crohn's disease. It is unknown which nutrient(s) account for this action, but a role for both the amount and type of dietary fat has been postulated. Some clinical and experimental data suggest that medium-chain triglycerides (MCT) may reduce intestinal inflammation. We aimed to assess the effect of replacing part of the dietary fat with MCT on the incidence and severity of colitis in interleukin (IL)-10(-/-) mice under specific pathogen-free conditions. Twenty-four IL-10(-/-) 4-wk-old mice were randomized to receive a control diet based on sunflower oil [(n-6) fatty acids (FA)] and an experimental isocaloric, isonitrogenous diet with 50% sunflower and 50% coconut oil (MCT diet). When the mice were 12 wk old, they were killed and the colon was examined for the presence of colitis, lymphocyte subpopulations and apoptosis, ex vivo cytokine production in supernatant of colon explants, toll-like receptor (TLR)-2 and TLR-9 mRNA, and FA profile in colonic tissue homogenates. Colitis incidence was lower in the IL-10(-/-) mice fed the MCT diet (1/12) than in the mice fed the control diet (8/12; P = 0.03). The histological damage score was also lower in the former (P < 0.0005). Feeding the MCT diet resulted in fewer total and apoptotic intraepithelial CD3+ and lamina propria CD3+CD4+ lymphocytes, as well as downregulated production of IL-6 and interferon-gamma, and reduced TLR-9 mRNA. We conclude that partial replacement of dietary (n-6) FA with MCT decreases the incidence of colitis in a model of spontaneous intestinal inflammation and provide experimental arguments for a possible primary therapeutic effect of MCT in human Crohn's disease

Refinements in husbandry, care and common procedures for non-human primates: Ninth report of the BVAAWF/FRAME/RSPCA/UFAW Joint Working Group on Refinement

This report produced by the British Veterinary Association Animal Welfare Foundation (BVAAWF)/Fund for the Replacement of Animals in Medical Experiments (FRAME)/Royal Society for the Prevention of Cruelty to Animals (RSPCA)/Universities Federation for Animal Welfare (UFAW) Joint Working Group on Refinement (JWGR) sets out practical guidance on refining the husbandry and care of non-human primates (hereinafter primates) and on minimizing the adverse effects of some common procedures. It provides a valuable resource to help understand the physical, social and behavioural characteristics and needs of individual primates, and is intended to develop and complement the existing literature and legislative guidelines. Topics covered include refinements in housing, husbandry and common procedures such as restraint, identification and sampling, with comprehensive advice on issues such as primate communication, assessing and facilitating primate wellbeing, establishing and maintaining social groups, environmental and nutritional enrichment and animal passports. The most commonly used species are the key focus of this resource, but its information and recommendations are generally applicable to other species, provided that relevant individual species characteristics are taken into account
