The Mediterranean population of tomato leaf curl New Delhi virus (ToLCNDV-ES) is characterized by a high genetic uniformity, distinguishing it from its Asian counterparts. ToLCNDV-ES is thought to have a monophyletic origin, likely resulting from a single recombination event, prior to its spread throughout the Mediterranean region. Following its first detection in southeastern France in 2020, ToLCNDV-ES re-emerged in France in 2022. Our analysis based on advanced long-read sequencing, circular DNA profiling, and phylogeny indicates both local persistence of French ToLCNDV-ES and multiple independent introduction events. Signatures of positive selection were identified in French ToLCNDV-ES populations, whereas no clear evidence of recombination was found. Bayesian time-structured phylogenetic analyses suggest that introductions in France occurred between 2018 and 2021 from the major ToLCNDV-ES clade, while several Italian ToLCNDV-ES isolates diverged prior to the virus introduction in the Mediterranean basin. Overall, this study demonstrates the value of an optimized long-read sequencing approach for resolving circular DNA virus diversity, and sheds light on the complex evolutionary history of ToLCNDV-ES in the Mediterranean Basin, particularly in southeastern France.
Despite progress realised in transplantation and organ procurement, there is an increasing gap between the number of patients on the national waiting list and the number of harvested organs. As a result, the appropriate organs must be matched with the appropriate patient, with two constraints: equity and efficacy. In a context of lack of organs, another public health problematic is to conciliate both the interests of a given patient and the interests of those on the waiting lists. In 1996, the French secretary of state for health instituted a public consultation committee chaired by the vice-president of the Comité consultatif national d'éthique, Counsellor Jean Michaud, to study organ allocation rules and to plan recommendations for the future. Using, as a starting point, the allocation rules initiated in the past by France Transplant and transiently applied by l'Etablissement français des Greffes, the committee conducted a large audition of health care professionals concerned with transplantation, individuals qualified in ethics, laws, sociology or ethnology, politicians and a sample representation of the population. A new corpus of allocation rules and procedures was then defined according to the committee recommendations and the advice of all medico-surgical transplantation teams, and published as a ministerial order in the Journal officiel de la République française in november 1996. It specifies shared principles and organ by organ specific allocation rules.
