Northern Normal: Laboratory Networks, Microbial Culture Collections, and Taxonomies of Power (1939–2000)

Engaging Science, Technology, and Society
Bacteriophage-typing – using bacterial viruses to identify bacteria at the species and strain level – was the gold standard technology underlying the rapid expansion of international surveillance for major bacterial pathogens after 1945.

Investigation of a Listeria monocytogenes Chromosomal Immigration Control Region Reveals Diverse Restriction Modification Systems with Complete Sequence Type Conservation

Microorganisms, 2023
Listeria monocytogenes is a Gram-positive pathogen responsible for the severe foodborne disease listeriosis. A chromosomal hotspot between lmo0301 and lmo0305 has been noted to harbor diverse restriction modification (RM) systems. Here, we analyzed 872 L.

DNA ejection from bacteriophage: towards a general behavior for osmotic suppression experiments [PDF]

The European Physical Journal E 24 (2007) 9-18, 2007
We present in this work in vitro measurements of the force ejecting DNA from two distinct bacteriophages (T5 and lambda) using the smotic-suppression technique. Our data are analyzed by revisiting the current theories of DNA packaging in spherical capsids.

Species and Type Phages of Lactococcal Bacteriophages

Intervirology, 1991
Lactococcal phages are classified according to morphology and DNA homology. Phages are differentiated into 12 phage species, and type phages of each species are proposed. Members and possible members of each species are named. Available data on type phages are tabulated including morphology, DNA characteristics and phage protein bands.

Diversity of Sinorhizobium (Ensifer) meliloti Bacteriophages in the Rhizosphere of Medicago marina: Myoviruses, Filamentous and N4-Like Podovirus [PDF]

, 2020
Using different Sinorhizobium meliloti strains as hosts, we isolated eight new virulent phages from the rhizosphere of the coastal legume Medicago marina.

Characterizing the bacteriophage PKp-V1 as a potential treatment for ESBL-producing hypervirulent K1 Klebsiella pneumoniae ST258 isolated from veterinary specimens. [PDF]

Vet World
Background and Aim: The dearth of new antibiotics necessitates alternative approaches for managing infections caused by resistant superbugs. This study aimed to evaluate the lytic potential of the purified bacteriophage PKp-V1 against extended-spectrum β-

Propionibacterium acnes bacteriophages display limited genetic diversity and broad killing activity against bacterial skin isolates. [PDF]

, 2012
UnlabelledInvestigation of the human microbiome has revealed diverse and complex microbial communities at distinct anatomic sites. The microbiome of the human sebaceous follicle provides a tractable model in which to study its dominant bacterial ...

Evolutionary interplay between viruses and R‐loops

FEBS Letters, EarlyView.
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

Spreading dynamics of an infection in a growing population [PDF]

arXiv, 2021
Bacteriophages spreading through populations of bacteria offer relatively simple, tuneable systems for testing mathematical models of range expansion. However, such models typically assume a static state into which to expand, which is not generally valid for bacterial-bacteriophage populations, where both the host (bacteria) and the infectious agent ...

Genome landscapes and bacteriophage codon usage [PDF]

Lucks JB, Nelson DR, Kudla GR, Plotkin JB (2008) Genome Landscapes and Bacteriophage Codon Usage. PLoS Computational Biology 4(2): e1000001, 2007
Across all kingdoms of biological life, protein-coding genes exhibit unequal usage of synonmous codons. Although alternative theories abound, translational selection has been accepted as an important mechanism that shapes the patterns of codon usage in prokaryotes and simple eukaryotes.
