Development of a modified QuEChERS method for multi-class pesticide analysis in human hair by GC-MS and UPLC-MS/MS

Luiz Felippe De Alencastro, Edouard René Gilbert Lehmann, Christelle Oltramare

The present study assessed the suitability of using QuEChERS procedure for the simultaneous deter- mination and quantification of 37 multi-class pesticides in human hair. Matrix co-eluted material had a large influence on instrumental response sensitivity. ...

Quantifying the impact of a periodic presence of antimicrobial on resistance evolution in a homogeneous microbial population of fixed size

Anne-Florence Raphaëlle Bitbol, Loïc Marrec

The evolution of antimicrobial resistance generally occurs in an environment where antimicrobial concentration is variable, which has dramatic consequences on the microorganisms' fitness landscape, and thus on the evolution of resistance. We investigate th ...

Assessment of human exposure to pesticides by hair analysis: The case of vegetable-producing areas in Burkina Faso

Luiz Felippe De Alencastro, Edouard René Gilbert Lehmann, Christelle Oltramare, Jean-Jacques Stéphane Nfon Dibie

The present work assesses human exposure to pesticides in vegetable-producing areas in Burkina Faso, using hair as an indicator. The study design includes a comparison between operators who are occupationally exposed while working in the fields and a refer ...

Antimicrobial resistance in leprosy: results of the first prospective open survey conducted by a WHO surveillance network for the period 2009-15

Stewart Cole

Objectives: Antimicrobial resistance (AMR) is a priority for surveillance in bacterial infections. For leprosy, AMR has not been assessed because Mycobacterium leprae does not grow in vitro. We aim to obtain AMR data using molecular detection of resistance ...

Dietary risk assessment of pesticides from vegetables and drinking water in gardening areas in Burkina Faso

Luiz Felippe De Alencastro, Edouard René Gilbert Lehmann

Vegetables and water samples have been collected around the lake of Loumbila in Burkina Faso. Pesticides resi- dues in food commodities were analyzed using a modified QuEChERS extraction method prior analysis on GC-MS and UPLC-MS/MS of 31 pesticides. Maxim ...

Impact Assessment of Pesticides Applied in Vegetable-Producing Areas in the Saharan Zone

Edouard René Gilbert Lehmann

The present thesis aimed at characterizing the extent of the pesticide contamination and resulting impacts on the environment and the human health in market garden-ing areas in Burkina Faso. Analytical procedures were developed and validated for multi-clas ...

The influence of particles on bioavailability and toxicity of pesticides in surface water

Environmental risk assessment is an essential part of the approval process for pesticides. Exposure concentrations are compared with ecotoxicological data obtained from standardized laboratory studies and, if available, from field studies to determine the ...

The gram-negative sensing receptor PGRP-LC contributes to grooming induction in Drosophila

Bruno Lemaitre

Behavioral resistance protects insects from microbial infection. However, signals inducing insect hygiene behavior are still relatively unexplored. Our previous study demonstrated that olfactory signals from microbes enhance insect hygiene behavior, and gu ...

Resistance of echovirus 11 to ClO2 is associated with enhanced host receptor use, altered entry routes and high fitness

Tamar Kohn, Anna Carratala Ripolles, Virginie Bachmann, Jeffrey David Jensen, Qingxia Zhong, Hyunjin Shim

Waterborne viruses can exhibit resistance to common water disinfectants, yet the mechanisms that allow them to tolerate disinfection are poorly understood. Here, we generated echovirus 11 (E11) with resistance to chlorine dioxide (ClO2) by experimental evo ...

New antimicrobial surfaces and intravascular catheters for the prevention of healthcare-associated infections

Myriam Koumba Sarah Ballo

Healthcare-associated infections (HAIs) are an important health issue around the world. The consequences of HAIs incidence include prolonged hospital stays, increased resistance of microorganisms to antimicrobials, higher costs for health systems and for t ...
