The identification of micro-organisms carried by ticks is an important issue for human and animal health. In addition to their role as pathogen vectors, are also the hosts symbiotic bacteria whose impact on tick biology poorly known. Among these, bacterium Wolbachia pipientis has already been reported associated with Ixodes ricinus other species. However, origins in consequences (known be very diverse invertebrates, ranging from nutritional symbionts nematodes reproductive manipulators...
The aims of this study were: (i) to determine the proportions Aeromonas spp. resistant florfenicol (FC), oxolinic acid (OA) and oxytetracycline (OTC) along a river receiving effluents from fish farms, (ii) assess relevance using bacterial group as an indicator for studying consequences use release these aquacultural antimicrobials in freshwater environment, compared with performing antimicrobial measurements sediments.Sediment interstitial waters sampled during two distinct climatic seasons...
A multiresistant Aeromonas bestiarum strain, shown to be persistent and spreading in a freshwater stream, was investigated for the presence, location organization of antimicrobial resistance genes. The plasmid pAB5S9 transferred by electroporation into Escherichia coli TG1. phenotype mediated determined. Moreover, sequenced completely analysed its structure reading frames. Plasmid resistances phenicols, sulphonamides, streptomycin tetracycline. analysis 24.7 kb sequence revealed presence 20...
Amplicon sequencing approaches have been widely used in food bacterial ecology. However, choices regarding the methodology can bias results. In this study, communities associated with cold-smoked salmon products and their processing plant surfaces were monitored via of V3-V4 region 16S rRNA gene. The impact DNA extraction protocols, sampling methods (swabbing or sponging) surface materials on investigated. α β diversity analyses revealed that mainly influence observed microbiota composition....
The mechanisms of resistance to quinolone and epidemiological relationships among A. salmonicida strains isolated from diseased fish in French marine farms 1998 2000 were investigated. resistance-determining regions the gyrA parC genes 12 clinical isolates with different levels susceptibility sequenced. MICs determined presence efflux pump inhibitor (EPI) Phe-Arg beta-naphthylamide E(max) values (MIC without EPI/MIC EPI) calculated. Isolates fell into two classes: (i) those that had a...
Abstract To determine characteristics of natural transmission Babesia sp. EU1 and B. divergens by adult Ixodes ricinus ticks, we examined tick salivary gland contents. We found that I. is a competent vector for their sporozoites directly invade erythrocytes. conclude naturally transmitted ricinus.
Cold-smoked salmon is a widely consumed ready-to-eat seafood product that fragile commodity with long shelf-life. The microbial ecology of cold-smoked during its shelf-life well known. However, to our knowledge, no study on the using next-generation sequencing has yet been undertaken. In this study, microbiotas were investigated polyphasic approach composed cultivable methods, V3—V4 16S rRNA gene metabarcoding and chemical analyses. Forty-five products processed in three different factories...
The rise of antibiotic resistance is not only a challenge for human and animal health treatments, but also posing the risk spreading among bacterial populations in foodstuffs. Farmed fish-related foodstuffs, food origin most consumed worldwide, are suspected to be reservoir genes resistant hazards. However, scant research has been devoted possible sources diversity fresh fillet ecosystems (farm environment including rivers practices, factory environment). In this study communities rainbow...
The consequences of antibiotic use in aquatic integrated systemset al.,which are based on trophic interactions between different cultured organisms and physical continuity through wateret al.,need to be examined. In this studyet al.,fish reared a prototype marine system were given an oxolinic acid treatmentet al.,during after which the level resistance quinolone was monitored among vibrio populations from digestive tracts treated fishet al.,co-cultured bivalves sediments that isolated...
The aim of this study was to develop a rapid and accurate PMA-qPCR method quantify viable Brochothrix thermosphacta in cold-smoked salmon. B. is one the main food spoilage bacteria. Among seafood products, salmon particularly impacted by spoilage. Specific sensitive tools that detect bacterium products are very useful. culture commonly used time-consuming can underestimate cells but not immediately culturable state. We designed new PCR primer set from single-copy rpoC gene. QPCR efficiency...
Study the relationship between antibiotic resistance patterns of Pseudomonas isolated from farmed rainbow trout fillets and farm or transformation process locations.Pseudomonas strains were sampled in two differently located farms filleted laboratory a processing factory. One hundred twenty-five isolates confirmed as belonging to using CFC selective media, Gram staining, oxidase test quantitative polymerase chain reaction methods. Fifty-one separate fish further identified MALDI-TOF mass...
