Physical characteristics of new coliphages

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.

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.

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.

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.

Active Form of Two Coliphage Repressors

Nature, 1970
Two coliphage repressers were originally isolated as monomeric proteins. Here it is shown that these repressers attach to DNA in the form of oligomers, possibly as tetramers, and that these oligomers are in rapid equilibrium with the monomers.

Physical map of coliphage N4 DNA

Virology, 1980
Abstract A detailed restriction endonuclease map of Escherichia coli phage N4 DNA is presented. The cleavage sites for restriction endonucleases Hae II (1 cut), Hha I (3 cuts), Xba I (5 cuts), Ava II (15 cuts), and Hpa I (25 cuts) have been determined by (1) digestion with endonucleases after end labeling of the DNA; (2) digestion with two ...

Coliphage survival in seawater

Water Research, 1985
Abstract The relative survival of coliphages isolated from seawater under controlled conditions in different media, in the laboratory and in the marine environment, was investigated. The results show that the survival under controlled conditions in different media, and also in the sea, is affected by biological and chemical factors.
