Cyclization of coliphage 186 DNA
Journal of Molecular Biology, 1967Equilibrium and kinetic studies have been made on the cyclization of coliphage 186 DNA. In 0·13 m -Na + , the melting temperature of the cohesive ends ( T m ), i.e. the midpoint of the linear monomer to cyclic monomer transition, occurs at 63°C, which is 12°C above that of λb2b5c DNA in the same medium.

The Calcium Requirement of Coliphage T5
The Journal of Immunology, 1949Abstract Stassano and de Beaufort (1) discovered that the growth of certain phages was inhibited by the presence of citrate in the culture medium, and that this inhibition could be overcome by the addition of calcium salts. Bordet and Renaux (2) investigated a strain of Shiga phage which was unable to lyse the host cells in the presence ...

Active Form of Two Coliphage Repressors
Nature, 1970Two 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.

Use of coliphages as indicators of water pollution
Canadian Journal of Microbiology, 1973The feasibility of using coliphages as indicators of sewage pollution was investigated. Standard coliform determinations (MPN) were also made to compare fluctuations in coliforms with fluctuations in their obligate parasites. No consistent relationship was found between coliform and coliphage levels.

Transduction by coliphage λ of the galactose marker
Virology, 1957Abstract Phages obtained by induction of strain C600 Gal + made lysogenic for λ ++ when infecting strain 112 Gal − sensitive transduce Gal + with low frequency. The strain C600 Gal + is stable; it does not segregate Gal − . The transformed strains are “heterogenotes.” These heterogenotes have the following properties: 1. 1. They are Gal +

A genetic study of the temperate coliphage λ
Virology, 1955Abstract 1. 1. All the known markers in the temperate phage λ are linked to each other. 2. 2. Mating between pairs of intracellular particles occurs at random with respect to partner but is rather rare (average number of rounds of mating 0.5, assuming two reciprocal recombinants are formed simultaneously). 3. 3.
