Soft-probe-scanning electrochemical microscopy reveals electrochemical surface reactivity of E. coli biofilms

Hubert Girault, Emad Oveisi, Horst Pick, Andreas Stephan Lesch, Sorour Darvishi

Investigating and understanding dynamic biofilm growth mechanisms is challenging, often because state-of-theart optical characterization tools provide limited information. Micrometric electrochemical imaging of Escherichia coli biofilms using Soft-Probe-Sc ...

Vancomycin resistance plasmids affect persistence of Enterococcus faecium in water

Suzanne Marie Young

Vancomycin resistant enterococci (VRE) cause 20,000 infections annually in the United States, most of which are nosocomial. Recent findings of VRE in sewage-contaminated surface waters demonstrate an alternate route of human exposure, and a possible settin ...

Population Structure, Molecular Epidemiology, and beta-Lactamase Diversity among Stenotrophomonas maltophilia Isolates in the United States

Luciano Andres Abriata

Stenotrophomonas maltophilia is a Gram-negative, nonfermenting, environmental bacillus that is an important cause of nosocomial infections, primarily associated with the respiratory tract in the immunocompromised population. Aiming to understand the popula ...

Thioester-containing proteins regulate the Toll pathway and play a role in Drosophila defence against microbial pathogens and parasitoid wasps

Bruno Lemaitre, Samuel Rommelaere, Anna Dostalova

Background: Members of the thioester-containing protein (TEP) family contribute to host defence in both insects and mammals. However, their role in the immune response of Drosophila is elusive. In this study, we address the role of TEPs in Drosophila immun ...

A Microfluidic Platform Enables Large-Scale Single-Cell Screening to Identify Genes Involved in Bacterial Persistence

Amanda Verpoorte

Persistent cells, representing a small fraction of a bacterial population, are refractory to antibiotic therapy. It is a phenotypic transient state. The underlying mechanisms of persistence remain largely unknown, but even divergent hypotheses agree on a f ...

Bactericidal activity and mechanism of action of copper-sputtered flexible surfaces against multidrug-resistant pathogens

César Pulgarin, Juan Kiwi, Sami Rtimi, Myriam Koumba Sarah Ballo

Using direct current magnetron sputtering (DCMS), we generated flexible copper polyester surfaces (Cu-PES) and investigated their antimicrobial activity against a range of multidrug-resistant (MDR) pathogens including eight Gram-positive isolates (three me ...

Identification of synthetic compounds active against VRE: the role of the lipidated aminoglucose and the structure of glycopeptide binding pocket

Jieping Zhu

A modified vancomycin binding pocket (D-O-E ring) incorporating an alpha -hydroxy-beta -amino acid at the AA4 position is designed and synthesized. Some of these compds. display potent bioactivities against both sensitive- and resistant-strains (8 micro g/ ...

Mycobacterium tuberculosis is a natural mutant with an inactivated oxidative-stress regulatory gene: implications for sensitivity to isoniazid

Stewart Cole

The systems participating in detoxification of reactive oxygen intermediates in Mycobacterium tuberculosis are believed to play a dual role in the biology of this highly adapted human pathogen: (i) they may contribute to the survival of this bacterium in t ...

Molecular characterization of the resolvase gene, res, carried by a multicopy plasmid from Clostridium perfringens: common evolutionary origin for prokaryotic site-specific recombinases

Stewart Cole

Clostridium perfringens strain CPN50 harbours a 10.2 kb plasmid known as pIP404 which, in addition to a set of UV-inducible genes involved in bacteriocin production, carries res, a gene probably encoding a site-specific recombinase. The RES protein is high ...
