Abstract

D. J. McCORQUODALE Division of Biology, University of Texas at Dallas, P. 0. Box 30365, Dallas, Texas 75230 Received February 4 1971 , ACTERIOPHAGE BF23 was isolated by FREDERICQ, has been used to and detect bacterial strains that are resistant to colicins of group E (FREDERICQ 1949). NISIOKA OZEKI(1968) noted that BF23 is related to T5 in its properand ties-both phages display virtually identical gross morphologies, both require calcium ions for multiplication, both have a minimal latent period of about 35 minutes, and both are restricted in their growth in cells of Escherichia coli carrying colicinogenic factor Ib (CoZIbf cells). Furthermore, these two phages undergo phenotypic mixing and, as we will report in a later publication, they readily recombine genetically with one another. Restriction of the growth of BF23 by colicinogenic factor Ib was first observed by STROBEL NOMURA and (1966). Their work was subsequently extended by NISIOKA OZEKI (1968). Our present knowledge of this restriction may be and summarized as follows.
