Electron microscopic study of parental strains E. coli K12, E. coli 0124 : K72 (B17 and of recombinations demonstrated that their populations were nonhomogeneous and, along with the common ones, contained maxi- and mini-cells. By the character of flagellae and fimbria inheritance recombinations were distributed into two groups: similar to the donor and similar to the recipient. The data of electron microscopic determination of the flagellae and fimbria failed to coincide with the data on mobility and capacity to agglutinate erythrocytes in all the strains under study; this pointed to the nonhomogeneity of bacterial population in respect to these signs. There were revealed recombinations of E. coli O124 in which the majority of the population cells had flagellae, but proved to be immobile; this indicated a possibility of independent transfer of genes controlling the morphogenesis and the function of the flagellae to the E. coli O124 recombinations. |
