Artemisinin resistance (delayed P. falciparum clearance following artemisinin-based combination therapy), is widespread across Southeast Asia but to date has not been reported in Africa1-4. Here we genotyped the P. falciparum K13 (Pfkelch13) propeller domain, mutations in which can mediate artemisinin resistance5,6, in pretreatment samples collected from recent dihydroarteminisin-piperaquine and artemether-lumefantrine ...

Serratia vespertilionis (García-Fraile et al. 2015) is a later heterotypic synonym of Serratia ficaria (Grimont et al. 1981).

Paula García-Fraile, Cathrin Spröer, Olivier Chesneau, Alexis Criscuolo, Elke Lang, Dominique Clermont,

A previous 16S rRNA gene sequence comparison had demonstrated that the type strains of Serratia vespertilionis and Serratia ficaria shared 99.5 % sequence similarity. Despite the 56.2 % homology by DNA-DNA hybridization previously found between these strains, the results of an in silico whole-genome sequence comparison and a new DNA-DNA hybridization study ...

Genus-wide Yersinia core-genome multilocus sequence typing for species identification and strain characterization.

Cyril Savin, Alexis Criscuolo, Julien Guglielmini, Anne-Sophie Le Guern, Elisabeth Carniel, Javier Pizarro-Cerdá, Sylvain Brisse,

The genus Yersinia comprises species that differ widely in their pathogenic potential and public-health significance. Yersinia pestis is responsible for plague, while Yersinia enterocolitica is a prominent enteropathogen. Strains within some species, including Y. enterocolitica, also vary in their pathogenic properties. Phenotypic identification of Yersinia species is time-consuming, labour-intensive and ...

Alexis Criscuolo, Sylvie Issenhuth-Jeanjean, Xavier Didelot, Kaisa Thorell, James Hale, Julian Parkhill, Nicholas R Thomson, François-Xavier Weill, Daniel Falush, Sylvain Brisse,

Bacteria and archaea make up most of natural diversity, but the mechanisms that underlie the origin and maintenance of prokaryotic species are poorly understood. We investigated the speciation history of the genus Salmonella, an ecologically diverse bacterial lineage, within which S. enterica subsp. enterica is responsible for important human food-borne ...

The population structure of Clostridium tetani deduced from its pan-genome.

Diana Chapeton-Montes, Lucile Plourde, Christiane Bouchier, Laurence Ma, Laure Diancourt, Alexis Criscuolo, Michel Robert Popoff, Holger Brüggemann,

Clostridium tetani produces a potent neurotoxin, the tetanus neurotoxin (TeNT) that is responsible for the worldwide neurological disease tetanus, but which can be efficiently prevented by vaccination with tetanus toxoid. Until now only one type of TeNT has been characterized and very little information exists about the heterogeneity among C. ... Read more >>

Simulation data for the estimation of numerical constants for approximating pairwise evolutionary distances between amino acid sequences.

Thomas Bigot, Julien Guglielmini, Alexis Criscuolo,

Estimating the number of substitution events per site that have occurred during the evolution of a pair of amino acid sequences is a common task in phylogenetics and comparative genomics that often requires quite slow maximum-likelihood procedures when taking into account explicit evolutionary models. Data presented in this article are ... Read more >>
