Inducible viral receptor, A possible concept to induce viral protection in primitive immune animals
A pseudolysogen (PL) is derived from the lysogenic Vibrio harveyi (VH) which is infected with the VHS1 (Vibrio harveyi Siphoviridae-like 1) bacteriophage. The lysogenic Vibrio harveyi undergoes an unequivalent division of the extra-chromosomal VHS1 phage

The association of temperate phages and bacterial hosts during lysogeny manipulates microbial dynamics from the oceans to the human gut. Lysogeny is well studied in laboratory models, but its environmental drivers remain unclear.

Spontaneous Lysis in Lysogenic Staphylococci.
SummaryCultures of lysogenic staphylococci yielded significantly higher plaque counts when plated directly on streptomycin or penicillin with antibiotic resistant indicator strains than when supernatants of centrifuged cultures were assayed. This occurs at cell concentrations that permit significant read-sorption of free phage, which are inactivated ...

The Lysogenicity of Staphylococci isolated in Poland [PDF]
SUMMARY: Strains of staphylococci were tested for lysogenicity and different ‘lysogenicity patterns’ were defined on the basis of the phage lytic spectra. The test of lysogenicity was used to indicate the pathogenicity, and to complement the phage-typing pattern. None of the coagulase-negative strains (65) carried a phage.

Recombinants of a defective lysogen of staphylococcal strains.
When certain staphylococci are lysogenized with serotype A phages, a resident defective prophage is dislodged. The extent of the genome of this resident prophage was examined by studying the progeny from recombination between it and an invading phage ...

Similar to Pavlov's dog experiment, where two different stimuli can elicit the same response, environmental bacteria exposed to one of two simultaneous and unrelated stimuli may eventually trigger responses to both. ABSTRACT The canonical arsRBC genes of the ars1 operon in Pseudomonas putida KT2440, which confer tolerance to arsenate and arsenite, are ...

Estimating the Importance of Viral Contributions to Soil Carbon Dynamics
Written Summary: Viruses are ubiquitous in soils and impact global carbon cycling through infection of microbial hosts. Using existing data from the literature, we generate a global budget of the carbon potentially released from microbial biomass by viral infections in soils.

Superinfection of Lysogenic Strains of Salmonella typhimurium Q1: Prophage Substitution and Double Lysogenization [PDF]
SUMMARY: Strains of Salmonella typhimurium Q1, lysogenized with type A phages, were superinfected with the heterologous free phages of the same group. This produced lysis (productive or vegetative development) and prophage change (either prophage substitution or double lysogenization) in a constant pattern.

DNA Packaging Specificity in the λ‐Like Phages: Gifsy‐1
Dimeric λ TerS and chimera transition points. The N‐termini of each TerS derives from a λ‐like source phage: Gifsy‐1, 21, and N15 (labeled arrows). The N‐terminus includes the winged‐helix‐turn‐helix (HTH) DNA‐binding motif that confers the source phage's DNA packaging specificity.

Bacterial ‘Grounded’ Prophages: Hotspots for Genetic Renovation and Innovation
Bacterial genomes are highly plastic allowing the generation of variants through mutations and acquisition of genetic information. The fittest variants are then selected by the econiche thereby allowing the bacterial adaptation and colonization of the ...
