Imaging of microbial interactions has so far been based on well‐established electron microscopy methods. This study presents a new way to study bacterial colonies and interactions between bacteria and their viruses, bacteriophages (phages), in situ on agar plates using helium ion microscopy (HIM). In biological imaging, HIM has advantages over traditional scanning electron microscopy with its sub‐nanometer resolution, increased surface sensitivity, and the possibility to image nonconductive…

TLDR
In situ characterization of bacteria-nanopillar interactions in real-time close to its natural state using helium ion microscopy and 3D structured illumination microscopy techniques to understand the interaction of Gram-negative bacterial membranes with nanopillars such as those found on dragonfly wings.

Imaging Techniques for Detecting Prokaryotic Viruses in Environmental Samples

TLDR
The current state of the art of imaging techniques available for characterizing viruses in environmental samples are summarized and potential links between viral imaging and environmental genomics for shedding light on the morphology of uncultivated viruses and their lifestyles in Earth’s ecosystems are discussed.

Have an Ion on It: The Life‐Cycle of Bdellovibrio bacteriovorus Viewed by Helium‐Ion Microscopy

TLDR
The high resolution, the large depth of focus, and surface sensitivity of HIM hold promise to expand future studies on so far neglected ecological interactions within the microbial food web, in particular in samples with pronounced topography such as bacterial biofilms.

Bacteriophage-mediated identification of bacteria using photoacoustic flow cytometry

TLDR
It is demonstrated that E. coli can be detected and discriminated from Salmonella using this method, and it is hoped that this technology will decrease the time required to identify bacterial species from 3 to 4 days to less than 1 hour.

Bacteriophage Adherence to Mucus Mediates Preventive Protection against Pathogenic Bacteria

TLDR
Phages bind both to porcine mucus and to rainbow trout (Oncorhynchus mykiss) primary mucus, persist up to 7 days in the mucosa, and provide protection against Flavobacterium columnare, and exposure to mucus changes the bacterial phenotype by increasing bacterial virulence and susceptibility to phage infections.
