Cecropins contribute to Drosophila host defense against a subset of fungal and Gram-negative bacterial infection

Bruno Lemaitre, Alexia Laurie Carboni, Mark Austin Hanson

Cecropins are small helical secreted peptides with antimicrobial activity that are widely distributed among insects. Genes encoding Cecropins are strongly induced upon infection, pointing to their role in host defense. In Drosophila, four cecropin genes cl ...

Fluorescent D-Amino Acids for Super-resolution Microscopy of the Bacterial Cell Wall

Luc Reymond, Suliana Manley, Ophélie Rutschmann, Juliette Griffie, Chen Zhang, Willi Leopold Stepp, Jiangtao Qiao, Faustine Ambroisine Charline Ryckebusch

Fluorescent D-amino acids (FDAAs) have previ-ously been developed to enable in situ highlighting of locations of bacterial cell wall growth. Most bacterial cells lie at the edge of the diffraction limit of visible light; thus, resolving the precise details ...

Photodynamic treatment of multidrug-resistant bacterial infection using indium phosphide quantum dots

Francesco Stellacci, Inyoung Yonah Lee

Infections caused by multidrug-resistant (MDR) bacteria pose an impending threat to humanity, as the evolution of MDR bacteria outpaces the development of effective antibiotics. In this work, we use indium phosphide (InP) quantum dots (QDs) to treat infect ...

Preexisting Heterogeneity of Inducible Nitric Oxide Synthase Expression Drives Differential Growth of Mycobacterium tuberculosis in Macrophages

John McKinney, Ophélie Rutschmann, Chiara Toniolo

Mycobacterium tuberculosis infection is initiated by the inhalation and implantation of bacteria in the lung alveoli, where they are phagocytosed by macrophages. Even a single bacterium may be sufficient to initiate infection. Thereafter, the clinical outc ...

Carbon nanotube uptake in cyanobacteria for near-infrared imaging and enhanced bioelectricity generation in living photovoltaics

Vitalijs Zubkovs, Ardemis Anoush Boghossian, Alessandra Antonucci, Charlotte Elisabeth Marie Roullier, Nils Schürgers, Benjamin Paul Johanès Gabriel Lambert, Alice Judith Gillen, Melania Reggente, Mohammed Mouhib

Single-walled carbon nanotubes (SWCNTs) have unique optoelectronic properties that make them suitable for applications ranging from phototherapy to imaging and sensing, but their uptake has mainly been explored in eukaryotic cells. Here the authors explore ...

Preparation and Analysis of Bacteria Surface-Modified with Polymer Nanoparticles

Lisa Patricia Elisabeth Bader

Cell-based drug carriers present an interesting approach to improve the targeted delivery of therapeutic drugs in vivo. Specifically, bacterial cells possess interesting properties such as motility and sensing that allow some strains to selectively target ...

Natural competence of the pathogen Acinetobacter baumannii: an elusive phenomenon

Nina Vesel

Natural competence for transformation is an important driver of horizontal DNA exchange between different organisms. This can result in accumulation of dangerous genetic features, such as antibiotic resistance genes, in a single organism. One example of an ...

Identification of genes required for host-cell adhesion and antibiotic persistence of uropathogenic Escherichia coli via high-content screening

Thomas Marie Simonet

Uropathogenic Escherichia coli (UPEC) are the most common bacterial pathogens causing urinary tract infections (UTIs). Driven by the development of antibiotic resistant UPEC strains, UTIs have become a major public health issue and generate substantial hea ...
