The Calcium Requirement of Coliphage T5

The Journal of Immunology, 1949
Abstract 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, 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.

Use of coliphages as indicators of water pollution

Canadian Journal of Microbiology, 1973
The 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, 1957
Abstract 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, 1955
Abstract 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.

Polyconfiguron-model for the A-protein of coliphage MS2

Biochemical and Biophysical Research Communications, 1978
Abstract An algorithm is presented for decoding mRNA to give the tertiary structure of A-protein of MS2 coliphage. The scale model for the A-protein was assembled by stepwise “translation” of each codon into the corresponding amino acid configuron, so that a polyconfiguron composed of the 393 amino acid residues of the A-protein was generated.
