[Compatibility between F-like genetic transfer factors].

A study has been made of compatibility among four F-like factors of genetic transfer (pAP22-4, pAP38, pAP39 and pAP41) labeled separately by transpozones Tn1 and Tn9. It has been established that pAP38 transfer factor is compatible with plasmids pAP22-4, pAP39 and pAP412, while pAP41 transfer factor is compatible with plasmids pAP22-4 and pAP38 but is incompatible with plasmid pAP39.

[Atypical incompatibility of the F-like factors of pA22-4, pAP39 and pA41 genetic transfer with the F-group incompatibility plasmids].

A study was made of compatibility of three F-like factors of the genetic transfer (pAP22-4, pAP39, pAP41) identified in the cells of serologically typed E. coli strains with F-group incompatibility reference plasmids. The factors of pAP22-4 and pAP41 transfer are partly incompatible with groups FII, FIII, FIV, and FI, FIV, respectively, while the factors of pAP39 transfer are completely incompatible both with groups FI and FIV plasmids.

[Test-strains of E. coli for detection of chemical mutagens].

Two temperature-sensitive mutants--AP 16 and AP 18 were isolated after the treatment of E. coli AB2500 strain with two mutagens (acridine orange and 5-bromuracil). The mutants obtained proved to be sensitive and formed revertants when treated with the following agents: N-methyl-N'-nitro-N-nitrosoguanidine, hydroxylamine, nitrous acid, sodium metabisulfite, methylmethansulfonate, and proflavine. Introduction into the mentioned strains of additional mutation causing elevation of their sensitivity to crystal violet increased somewhat their capacity to form revertants under the effect of proflavine and methylmethansulfonate.
