Continuous surveillance of COVID-19 diffusion remains crucial to control its and anticipate infection waves. Detecting viral RNA load in wastewater samples has been suggested as an effective approach for epidemic monitoring the development warning system. However, quantitative link status stages outbreak is still elusive. Modelling thus address these challenges. In this study, we present a novel mechanistic model-based reconstruct complete dynamics from SARS-CoV-2 wastewater. Our integrates...
While MALDI-TOF mass spectrometry (MS) is widely considered as the reference method for rapid and inexpensive identification of microorganisms in routine laboratories, less attention has been addressed to its ability detection antimicrobial resistance (AMR). Recently, some studies assessed potential application together with machine learning AMR clinical pathogens. The scope this study was investigate MS protein spectra combined a prediction approach an screening tool relevant foodborne...
Abstract Campylobacteriosis has increased markedly in Luxembourg during recent years. We sought to determine which Campylobacter genotypes infect humans, where they may originate from and how humans. Multilocus sequence typing was performed on 1153 jejuni 136 C. coli human strains be attributed three putative animal reservoirs (poultry, ruminants, pigs) environmental water using the asymmetric island model. A nationwide case-control study (2010–2013) for domestic campylobacteriosis also...
Water scarcity is among the major crucial issues confronting humanity, caused by world's growth in population, socio-economic development and global climate change. Several desalination technologies are available to tackle increased freshwater water demand. Therefore, solar energy-driven distillation most conceivable alternatives for supplying safe with reducing energy cost. The conventional distiller a sustainable economical process. However, overall productivity generally low. In this...
Understanding the persistence of SARS-CoV-2 biomarkers in wastewater should guide wastewater-based epidemiology users selecting best RNA for reliable detection virus during current and future waves pandemic. In present study, endogenous were assessed one month six different pepper mild mottle (PMMoV) at three temperatures (4, 12 20 °C) sample. All consistently detected 6 days 4° differences signal among mostly observed °C with N being globally more persistent than RdRP, E ORF1ab ones....
Biofilms colonizing surfaces inside drinking water distribution networks may provide a habitat and shelter to pathogenic viruses parasites. If released from biofilms, these pathogens disseminate in the system cause waterborne diseases. Our study aimed investigate interactions of protozoan parasites (Cryptosporidium parvum Giardia lamblia [oo]cysts) (vaccinal poliovirus type 1, phiX174, MS2) with two contrasting biofilms. First, attachment, persistence, detachment were assessed biofilm. This...
This study presents an original rDNA PCR and microscopic survey of pelagic freshwater fungal communities, was designed to unveil the diversity true Fungi (i.e. kingdom Eumycota) in three contrasting lake ecosystems (Lakes Pavin, Aydat Vassivière) located French Massif Central. Three clone libraries were constructed from samples collected euphotic layers lakes during spring 2007. Phylogenetic analysis combined data clustered our sequences into thee divisions: Chytridiomycota (50% total...
Monitoring SARS-CoV-2 in wastewater has shown to be an effective tool for epidemiological surveillance. More specifically, RNA levels determined with RT-qPCR have been track the infection dynamics within population. However, surveillance of individual lineages circulating population based on genomic sequencing samples is challenging, as genetic material constitutes a mixture different viral haplotypes. Here, we identify specific signature mutations from estimate Luxembourg. We compare and...
High-resolution vertical sampling and determination of viral prokaryotic parameters in a deep volcanic lake shows that the absence thermal stratification but within light, oxygen, chlorophyll gradients, host availability empirically is prevalent over physical chemical environments favors lytic lysogenic "viral life cycles."
Development of TaqMan MGB real-time PCR assays for quantitative typing major cattle and human-pathogenic Cryptosporidium species.Three specific PCRs, based on the SSU rRNA gene, were directed towards livestock-restricted andersoni bovis as well both parvum hominis. A generic assay further identified all known species simultaneously monitored inhibition through an external amplification control. The highly reproducible, displayed a detection limit one oocyst per reaction. protocols also...
Heavy rainfall events were previously reported to bring large amounts of microorganisms in surface water, including viruses. However, little information is available on the origin and transport viral particles water during such rain events. In this study, an integrative approach combining microbiological hydrological measurements was investigated appreciate dynamics origins F-specific RNA bacteriophage fluxes two distinct rainfall-runoff A high frequency sampling (automatic sampler) set up...
