Bacteriophage effect on parasitism resistance [PDF]
arXiv, 2022 Many studies have shown that the protection of the host $\it{Acyrthosiphon~pisum}$ (Hemiptera, Aphididae) against the parasitoid $\it{Aphidius~ervi}$ (Hymenoptera, Braconidae) is conferred by the interaction between the secondary endosymbiont $\it{Hamiltonella~defensa}$ and the bacteriophage $\it{APSE}$ ($\it{Acyrthosiphon~pisum}$ secondary ...

Engineering Bacterial Secretion Systems for Enhanced Tumor Imaging and Surgical Guidance
Advanced Materials, EarlyView.This study presents a novel contrast agent platform, Streptavidin Associated Salmonella (SAS), for fluorescence image guided surgery. SAS selectively colonizes tumors and secretes streptavidin, enabling precise delineation of invasive tumor margins with prolonged signal retention.

A mechanical model of bacteriophage DNA ejection [PDF]
, 2017 Single molecule experiments on bacteriophages show an exponential scaling for the dependence of mobility on the length of DNA within the capsid. It has been suggested that this could be due to the "capstan mechanism" -- the exponential amplification of friction forces that result when a rope is wound around a cylinder as in a ship's capstan.

Isolation and characterization of Campylobacter bacteriophages from retail poultry [PDF]
, 2003 The ability of phages to survive processing is an important aspect of their potential use in the biocontrol of Campylobacter in poultry production. To this end, we have developed a procedure to recover Campylobacter bacteriophages from chilled and frozen
