Bacteriophage inhibition in staphylococci.
The inhibitory effect of high-titre preparations of phage 47 on certain strains of Staphylococcus aureus belonging to phage group I11 was produced with a phage: cell ratio of approximately 1 : 1. Staphylococci showing inhibition by preparations of phage 47 were converted to phage sensitivity by lysogenization with a phage derived from a strain sensitive to phage 47. Multiplication of phage 47 i...

متن کاملThe Rôle of Intracellular Bacteriophage in Lysis of Susceptible Staphylococci
In a previous paper on the kinetics of the bacterium-bacteriophage reaction (1) it was shown that under certain set conditions lysis of susceptible staphylococci occurs when the total phage i.e., extracellular plus intracellular phage, present in a bacterium-bacteriophage mixture attains a value of 125 activity units (2, 3) per organism, and that lysis is not determined by the total quantity of...
متن کاملBacteriophage Inhibition by Serum *
The inactivation of staphylococcus bacteriophage by an artificially produced anti-phagic serum was first reported by Gratia and Jaumain", who also found that normal rabbit serum inhibits staphy phage,-in some instances to a titer. as high as 1: 500. More recently it has been observed (Rosenthal29, Raiga24 25, Biglieri and Fischer4, Applebaum and MacNeal2, Colvin8, and Evans"0) that normal human...
متن کاملA specific reversible inhibition of bacteriophage T2.
With most phages, the titer of a lysate measured by plaque count remains stable from the time of lysis or shows a progressive decrease as phage becomes inactivated by a variety of environmental agents. Freshly prepared lysates of bacteriophage T2 of Escherichia coli rise in titer spontaneously with time, the maxmum titer being reached in several weeks under refrigeration. Bertani (unpublished d...
