Transcriptome analysis revealed that a quorum sensing system regulates the transfer of the pAt megaplasmid in Agrobacterium tumefaciens.

2016

Background Agrobacterium tumefaciens strain P4 is atypical, as the strain is not pathogenic and produces a for this species unusual quorum sensing signal, identified as N-(3-hydroxy-octanoyl)-homoserine lactone (3OH,C8-HSL). Results By sequence analysis and cloning, a functional luxI-like gene, named cinI, has been identified on the At plasmid of A. tumefaciens strain P4. Insertion mutagenesis in the cinI gene and transcriptome analyses permitted the identification of 32 cinI-regulated genes in this strain, most of them encoding proteins responsible for the conjugative transfer of pAtP4. Among these genes were the avhB genes that encode a type 4 secretion system (T4SS) involved in the forma…

International audience; A pilot study to test the efficacy of combining an organophosphate-based insecticide paint and pyrethroid-treated Long Lasting Insecticide Treated Nets (LLINs) against pyrethroid-resistant malaria vector mosquitoes was performed in a real village setting in Burkina Faso. Paint Inesfly 5A IGR™, comprised of two organophosphates (OPs) and an Insect Growth Regulator (IGR), was tested in combination with pyrethroid-treated LLINs. Efficacy was assessed in terms of mortality for 12 months using Early Morning Collections of malaria vectors and 30-minute WHO bioassays. Resistance to pyrethroids and OPs was assessed by detecting the frequency of L1014F and L1014S kdr mutation…

Abstract Background A novel strategy applying an organophosphate-based insecticide paint on doors and windows in combination with long-lasting insecticide-treated nets (LLINs) was tested for the control of pyrethroid-resistant malaria vectors in a village setting in Vallée du Kou, a rice-growing area west of Burkina Faso. Methods Insecticide Paint Inesfly 5A IGR™, comprised of two organophosphates and an insect growth regulator, was applied to doors and windows and tested in combination with pyrethroid-treated LLINs. The killing effect was monitored for 5 months by early morning collections of anophelines and other culicids. The residual efficacy was evaluated monthly by WHO bioassays using…

“Audacem faciebat amor” : Thisbe, an Ovidian Heroine from Antiquity to the 15th century

2022

In the Middle Ages, the fable of Pyramus and Thisbe from Ovid's Metamorphoses and older sources presents a range of varied representations, translated, reworked, transposed to serve literary, allegorical and moral purposes. This timeless love story has been adapted to multiples genres and purposes and became part of the literary and pictorial collective imagination. We explore the multiform reception of this fable to the 15th century in Latin and vernacular texts along with their illustrations in order to draw its diachronic evolution from its origins. We try to understand how authors appropriate the myth and deliver their own interpretation according to the context by filtering the element…

First phenotypic description of Fasciola hepatica/Fasciola gigantica intermediate forms from the human endemic area of the Nile Delta, Egypt.

2007

Fasciola gigantica is the main fasciolid species in Africa; however, F. hepatica and F. gigantica overlap in some countries. Egypt deserves mentioning because of the emerging situation of human fascioliasis in the Nile Delta area. The morphometric characteristics of fasciolid adults infecting the main livestock species present in the Nile Delta human endemic area are analyzed through a computer image analysis system (CIAS) on the basis of standardized measurements known to be useful for the differentiation of both fasciolid species. This is the first time that such a study is performed in an African country and, therefore, the results are compared to (i) F. hepatica (European Mediterranean …

"Nodier and sadism: the "monstrous turpitudes" of Smarra"

2021

Nodier studies have scarcely examined the relationship between Nodier and Sade, the first one having apparently done everything to lessen his interest in the sulphurous work of the marquis. However, little is known, Nodier is the inventor, or the propagator of the word “sadism” in the French language, which appeared for the first time in 1834, in the 8th edition of the "Dictionnaire Universel" by Boiste, that, precisely, revised, amended and largely amplified by Nodier. The objective of this article is to shed light on this immorality-stricken relationship between a writer concerned about his reputation and in search of respectability (Nodier was elected to the Académie française in 1833, a…
