Control of plasmid replication in Escherichia coli: correlation of the membrane site of DNA replication with the bacterial segregation unit.

The fate of parental lambda genomes after superinfection of homoimmune lysogenic cells was studied. The data confirm a previous observation that in the presence of the lambda repressor, superinfecting lambda DNA does not become associated with replication sites on the bacterial cell membrane. Under these conditions, the nonreplicating, superinfecting phage genomes do not become associated with the bacterial segregation unit. These results support the concept that the attachment of DNA to the bacterial membrane at specific sites is involved in the control of both chromosome replication and segregation, as predicted by the replicon hypothesis.

A blue catalase screening test for pyuria and haematuria.

The blue catalase test is easy to perform and economical of materials. In a series of 529 adult female hospital patients it appeared to be a good screening test for pyuria and haematuria, detecting all but one of the specimens examined with more than 20 red and white cells combined per cubic millimetre of urine and 95.2% of those with more than 10 cells. It indicates a raised leucocyte or red cell excretion rate but is not a test for bacteriuria.
