Inhibitory Effect of Adefovir on Viral DNA Synthesis and Covalently Closed Circular DNA Formation in Duck Hepatitis B Virus-Infected Hepatocytes In Vivo and In Vitro

Delmas, Julien, Schorr, Olivier, Jamard, Catherine, Gibbs, Craig, Trépo, Christian, Hantz, Olivier, ...

The elimination of viral covalently closed circular DNA (CCC DNA) from the nucleus of infected hepatocytes is an obstacle to achieving sustained viral clearance during antiviral therapy of chronic...

Development of a New Oligonucleotide Array To Identify Staphylococcal Strains at Species Level

Giammarinaro, Philippe, Leroy, Sabine, Chacornac, Jean-Paul, Delmas, Julien, Talon, Regine

The genus Staphylococcus is made up of 36 validated species which contain strains that are pathogenic, saprophytic, or used as starter cultures for the food industry. An oligonucleotide array...

Atomic Resolution Structures of CTX-M β-Lactamases: Extended Spectrum Activities from Increased Mobility and Decreased Stability

Chen, Yu, Delmas, Julien, Sirot, Jacques, Shoichet, Brian, Bonnet, Richard

Extended spectrum β-lactamases (ESBLs) confer bacterial resistance to third-generation cephalosporins, such as cefotaxime and ceftazidime, increasing hospital mortality rates. Whereas these...

CMT-Type β-Lactamase TEM-125, an Emerging Problem for Extended-Spectrum β-Lactamase Detection†

Robin, Frédéric, Delmas, Julien, Archambaud, Maryse, Schweitzer, Cédric, Chanal, Catherine, Bonnet, Richard

The clinical strain Escherichia coli TO799 was resistant to penicillin-clavulanate combinations and ceftazidime and was not reproducibly detected as an extended-spectrum β-lactamase (ESBL) according...

qnrA in CTX-M-Producing Escherichia coli Isolates from France▿

Lavigne, Jean-Philippe, Marchandin, Hélène, Delmas, Julien, Bouziges, Nicole, Lecaillon, Evelyne, Cavalie, Laurent, ...

By PCR, we screened for qnr genes 112 clinical isolates of extended-spectrum β-lactamase-producing Escherichia coli collected from hospitals in France during 2004. For the first time, 7.7% of...

CTX-M β-Lactamase-Producing Escherichia coli in French Hospitals: Prevalence, Molecular Epidemiology, and Risk Factors▿

Lavigne, Jean-Philippe, Marchandin, Hélène, Delmas, Julien, Moreau, Jérôme, Bouziges, Nicole, Lecaillon, Evelyne, ...

In 2004, 65 CTX-M-producing Escherichia coli isolates were collected from infected patients in four French hospitals. The blaCTX-M-15 genes were predominant. Pulsed-field gel electrophoresis...

Evolution of TEM-Type Enzymes: Biochemical and Genetic Characterization of Two New Complex Mutant TEM Enzymes, TEM-151 and TEM-152, from a Single Patient▿ †

Robin, Frédéric, Delmas, Julien, Schweitzer, Cédric, Tournilhac, Olivier, Lesens, Olivier, Chanal, Catherine, ...

Two clinical isolates of Escherichia coli, CF1179 and CF1295, were isolated from a patient hospitalized in the hematology unit of the University Hospital of Clermont-Ferrand, Clermont-Ferrand,...

Evaluation of a New Chromogenic Medium, chromID VRE, for Detection of Vancomycin-Resistant Enterococci in Stool Samples and Rectal Swabs▿

Delmas, Julien, Robin, Frédéric, Schweitzer, Cédric, Lesens, Olivier, Bonnet, Richard

We compared ChromID VRE medium with Enterococcosel containing vancomycin for the detection of vancomycin-resistant Enterococcus in 1,007 specimens. ChromID VRE in combination with Gram straining...

TEM-158 (CMT-9), a New Member of the CMT-Type Extended-Spectrum β-Lactamases▿

Robin, Frédéric, Delmas, Julien, Brebion, Amélie, Dubois, Damien, Constantin, Jean-Michel, Bonnet, Richard

TEM-158 was found to include the substitutions previously observed for TEM-12 and TEM-35. This enzyme presented hydrolytic activity against ceftazidime and a high level of resistance against...

Evaluation of the Vitek 2 System with a Variety of Staphylococcus Species▿

Delmas, Julien, Chacornac, Jean Paul, Robin, Frédéric, Giammarinaro, Philippe, Talon, Régine, Bonnet, Richard
