Viral diversity is linked to bacterial community composition in alpine stream biofilms

Tom Ian Battin, Hannes Markus Peter, Paraskevi Pramateftaki, Meriem Bekliz

Biofilms play pivotal roles in fluvial ecosystems, yet virtually nothing is known about viruses in these communities. Leveraging an optimized sample-to-sequence pipeline, we studied the spatiotemporal turnover of dsDNA viruses associated with stream biofil ...

Phase separation in viral infections

Christina Ernst, Haohua Li

Viruses rely on the reprogramming of cellular processes to enable efficient viral replication; this often requires subcompartmentalization within the host cell. Liquid-liquid phase separation (LLPS) has emerged as a fundamental principle to organize and su ...

Structure and Function of the T4 Spackle Protein Gp61.3

Petr Leiman

The bacteriophage T4 genome contains two genes that code for proteins with lysozyme activity-e and 5. Gene e encodes the well-known T4 lysozyme (commonly called T4L) that functions to break the peptidoglycan layer late in the infection cycle, which is requ ...

Notch Signaling - a Booster of Chronic Lymphocytic Leukemia During Initiation and Disease Progression

Delphine Maude Tardivon

Chronic lymphocytic leukemia (CLL) is a B cell malignancy and represents the most common leukemia in adults within the Western world. This disease mainly affects the elderly, with a median age of diagnosis over 70. The disease course is highly variable amo ...

A Vibriophage Takes Antirepression to the Next Level

Melanie Blokesch, Leonardo Filipe Lemos Rocha

Since its isolation by Esther Lederberg, phage lambda and its repressor protein CI have contributed substantially to the advancement of molecular biology. In this issue of Cell Host & Microbe, Silpe et al. (2020) characterize the antirepressor Qtip of Vibr ...

E-coli-MS2 bacteriophage interactions during solar disinfection of wastewater and the subsequent post-irradiation period

César Pulgarin, Stefanos Giannakis, Anna Carratala Ripolles, Margaux Océane Voumard

In this study, the effect of MS2 bacteriophage on the inactivation of its Escherichia coli host was evaluated in an effort to recreate some the main factors governing solar disinfection of wastewater (namely microbial growth, infection, photonic flux). As ...

Sputtered Gum metal thin films showing bacterial inactivation and biocompatibility

César Pulgarin, Juan Kiwi, Sami Rtimi

Super-elastic Titanium based thin films Ti-23Nb-0.7Ta-2Zr-(O) (TNTZ-O) and Ti-24Nb-(N) (TN-N) (at.%) were deposited by direct current magnetron sputtering (DCMS) in different reactive atmospheres. The effects of oxygen doping (TNTZ-O) and/or nitrogen dopin ...

Structure of viral membrane-penetrating machines by electron cryo-microscopy and tomography

Sergey Nazarov

My PhD thesis aims to obtain the structure of several bacteriophages, including so-called “jumbo” phages, using the electron cryo-microscopy (cryo-EM) and to study the structural transformation of these viruses as they attach and infect the host cell. We a ...

Single-cell dynamics of the chromosome replication and cell division cycles in mycobacteria

John McKinney, Neeraj Dhar, Isabella Santi

During the bacterial cell cycle, chromosome replication and cell division must be coordinated with overall cell growth in order to maintain the correct ploidy and cell size. The spatial and temporal coordination of these processes in mycobacteria is not un ...

Dynamics of E. coli membrane cell peroxidation during TiO2 photocatalysis studies by ATR-FTIR spectroscopy and AFM microscopy

Juan Kiwi

Escherichia coli (E. coli) photokilling due to the TiO2 under light irradiation in a batch reactor was studied by using of attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR) and atomic force microscopy (AFM). The ATR-FTIR spectr ...
