High acquisition rate of extended-spectrum β-lactamase-producing Enterobacteriaceae among French military personnel on mission abroad, without evidence of inter-individual transmission

International audienceOBJECTIVES:Acquisition of extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-E) by Europeans travelling individually in high-endemicity countries is common. However, how the different ESBL-E strains circulate in groups of travellers has not been studied. We investigated ESBL-E transmission within several groups of French military personnel serving overseas for 4-6 months.METHODS:We conducted a prospective study among French military personnel assigned to Afghanistan, French Guiana or Côte d'Ivoire for 4-6 months. Faecal samples provided by volunteers before leaving and after returning were screened for ESBL-E isolates. ESBL Escherichia coli from each military group was characterized by repetitive element palindromic polymerase chain reaction (rep-PCR) fingerprinting followed, in the Afghanistan group, by whole-genome sequencing (WGS) if similarity was ≥97%.RESULTS:Among the 189 volunteers whose samples were negative before departure, 72 (38%) were positive after return. The highest acquisition rates were observed in the Afghanistan (29/33, 88%) and Côte d'Ivoire (39/80, 49%) groups. Acquisition rates on return from French Guiana were much lower (4/76, 5%). WGS of the 20 strains from the Afghanistan group that clustered by rep-PCR identified differences in sequence type, serotype, resistance genes and plasmid replicons. Moreover, single-nucleotide polymorphism (SNP) differences across acquired strains from a given cluster ranged from 30 to 3641, suggesting absence of direct transmission.CONCLUSIONS:ESBL-E. coli acquisition was common among military personnel posted overseas. Many strains clustered by rep-PCR but differed by WGS and SNP analysis, suggesting acquisition from common external sources rather than direct person-to-person transmission

Des sources du savoir aux médicaments du futur

L'origine des pharmacopées traditionnelles L'élaboration des pharmacopées Les médicaments du XXIe siècle Comment les connaissances des savoirs thérapeutiques se sont-elles transmises au travers des différentes cultures ? Cet ouvrage innovant, qui réunit les travaux présentés au 4e Congrès européen d'ethnopharmacologie, fait remonter à la préhistoire les sources des connaissances thérapeutiques. Si les pharmacopées écrites jalonnent l'histoire des grandes médecines savantes, d'autres modes d'accès à la connaissance semblent exister dans l'univers chamanique des sociétés de tradition orale ainsi que dans la façon dont les animaux malades se soignent par les plantes. L'évaluation des propriétés pharmaco-toxicologiques et chimiques des plantes d'usage traditionnel devrait par ailleurs favoriser le développement futur des médicaments à base de plantes, l'un des thèmes porteurs abordés dans cet ouvrage. Mais l'objectif de ce livre est aussi de susciter, partout dans le monde, de nouvelles thématiques de recherche dans le domaine de la préhistoire du médicament et de la compréhension de l'acquisition et de la transmission du savoir. Le développement du phytomédicament non toxique destiné à l'homme et à l'animal figure également parmi les enjeux majeurs de demain.The origin of traditional pharmacopoeias The development of pharmacopoeias The medicines of the XXIth century How have the traditional Therapeutical knowledges been transmited to the différent cultures? This innovating book containing the proceedings of the 4th European Congress of Ethnopharmacology return to prehistory the sources of fherapeutical knowledge and asks how the animals cure themselves with plants. If the printing pharmacopoeias ponctuate the history of learning medicines other way of accessibility to the knowledge seems exist in the world of shaman in society with oral tradition. Ethnopharmacological evaluation of traditional médicinal plant should favour the development of phytomedicine. The purpose of this publication is also to provide dues to scientists in the whole world and help them identify new avenues for research in the field of the prehistory of drugs, for a better understanding of the way knowledge is acquired and then transmitted, and for the development of non-toxic herbal medicines for administration to human and animal beings
