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 >>

Genetic mapping of specific interactions between Aedes aegypti mosquitoes and dengue viruses.

Thanyalak Fansiri, Albin Fontaine, Laure Diancourt, Valérie Caro, Butsaya Thaisomboonsuk, Jason H Richardson, Richard G Jarman, Alongkot Ponlawat, Louis Lambrechts,

Specific interactions between host genotypes and pathogen genotypes (G×G interactions) are commonly observed in invertebrate systems. Such specificity challenges our current understanding of invertebrate defenses against pathogens because it contrasts the limited discriminatory power of known invertebrate immune responses. Lack of a mechanistic explanation, however, has questioned the nature of ... Read more >>
