    Summary: This Open Access book is for scientists and experts who work on urban food policies. It provides a conceptual framework for understanding the urban food system sustainability and how it can be tackled by local governments. Written by a collective of researchers, this book describes the existing conceptual frameworks for an analysis of urban food policies, at the crossroads of the concepts of food system and sustainable city. It provides a basis for identifying research questions related to urban local government initiatives in the North and South. It is the result of work carried out within Agropolis International within the framework of the Sustainable Urban Food Systems program and an action research carried out in support of Montpellier Méditerranée Métropole for the construction of its agroecological and food policy.

    Studies of A. and G. Youmans on the experimental tuberculosis led to discovery of a fundamentally new type of vaccines (ribosomal vaccines) which proved to be highly effective in the prophylaxis of many experimental infections. Therefore it seems reasonable to prepare analogous vaccine from Shigellae for the study of its efficiency in experimental shigellosis. Ribosomal preparations from Shigella sonnei were prepared by sonic disruption of microbial cells followed by differential ultracentrifugation according to A. and G. Youmans' method with slight modifications. The yeild of ribosomal fraction was about 2 per cent by weight; all the series had an UV adsorption maximum at 260 nm, the ratio OD260:OD280 being approximately 2. They contained about 55% of RNA, 35% of protein and no more than 8% of saccharides. As shown by centrifugation in sucrose gradient and by analytical ultracentrifugation the preparations were homogeneous. The presence of undissociated ribosomes was confirmed by electron microscopy. Thus, the ribosomal preparations obtained proved to be sufficiently purified for carrying out experimental investigations of their biological activity.
