Indigenous Coliphages and RNA-F-Specific Coliphages Associated with Suspended Solids in the Activated Sludge Process

Water Science and Technology, 1989
The occurrence of indigenous coliphages and RNA-F-specific coliphages associated with suspended solids in the activated sludge process was investigated using E. coli K-12,F+(A/λ) as the host strain.

Coliphages as Model Organisms in the Characterization and Management of Water Resources [PDF]

Water (Switzerland), 2016
Two groups of bacteriophages that infect Escherichia coli, somatic and F-specific coliphages, have been used in academia as both fecal and viral indicators for many years.

The c-region of coliphage 21

Virology, 1967
Abstract Clear-plaque mutants of a 21-λ hybrid have been isolated. The mutants fall into 4 morphological classes and 3 of the classes behave as single complementation groups, cI, cII, and cIII. The map order, based on 3 point tests, is cIII, cI, cII … mi.

Biophysical properties of N4 coliphage

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1966
Abstract 1. 1. N4 bacteriophage, a recently isolated lysis-inhibiting phage active on Escherichia coli K12 strains, was purified from lysates with titres ranging from 5 to 10 · 10 11 plaque-forming units/ml, by several cycles of differential centrifugation followed by a final step of equilibrium centrifugation in CsCl.

Lethal lysogenization by coliphage lambda

Virology, 1976
Abstract Mutants of lambda insensitive to epistatic replication inhibition by repressor ( ri c ) were studied during lysogenization of sensitive host cells. These mutants establish defective complexes which neither lyse nor multiply as lysogens.

Canadian Journal of Microbiology, 1974
Seven new bacteriophages for Escherichia coli B, isolated from a farm animal waste lagoon, were characterized in regard to morphology, buoyant density, UV-sensitivity, and heat-sensitivity.

Rapid coliphage detection assay

Journal of Virological Methods, 2001
A rapid coliphage detection assay was developed, based on the phage-induced release of beta-galactosidase from cells of Escherichia coli. The assay could detect as few as five coliphage per sample without an overnight incubation period. The range of acceptable assay parameters was identified.

Structural proteins of coliphage N4

Virology, 1973
Abstract The proteins from bacteriophage N4, dissociated with 1% SDS and 2% 2-mercaptoethanol, have been investigated by SDS polyacrylamide gel electrophoresis. Ten different polypeptide chains were identified in the purified virus. The molecular weights of the protein monomers estimated by coelectrophoresis with marker proteins ranged from 31,000 to

RNA in Coliphage T5

Nature, 1973
VIRUSES are thought to have either RNA or DNA as their genetic material, but not both1, although oncogenic RNA viruses containing reverse transcriptase have been shown to contain some DNA. I did not expect to find that coliphage T5, a DNA-containing virus, also contained some RNA.
