Current evidence describing antimicrobial resistance (AMR) in the context of the Syrian conflict is of poor quality and sparse in nature. In this paper we explore and report the major drivers of AMR that were present in Syria pre-conflict and those that have emerged since its onset in March 2011. Drivers which existed before the conflict included a lack of enforcement of existing legislation to regulate over the counter antibiotics and notification of communicable diseases. This contributed to a number of drivers of AMR after the onset of conflict which were also compounded by the exodus of trained staff, the increase in overcrowding and unsanitary conditions, the increase in injuries and economic sanctions limiting the availability of required laboratory medical materials and equipment...

A predominance of the blaCTX-M-1 /IncHI1 plasmid combination in horses has been reported in Czech-Republic, Denmark, and The Netherlands. To clarify a possible specific plasmid epidemiology of blaCTX-M-1 in horses in a European perspective, a collection of 74 extended-spectrum beta-lactamase-producing Escherichia coli recovered from diseased horses in France and Sweden during the period 2009-2014 was investigated in respect of their genetic relatedness, plasmid content, and molecular features. Overall, 80% of E...
