title: R factors from Enterobacter group.
abstract: Twenty-six R factors transmissible to E. coli K12 were derived from 79 strains of Enterobacter species isolated in various clinical specimens (urine, sputum, blood, pus); 71 of 79 strains were Enterobacter cloacae. Fifteen R factors were fi+: 14 belonged to group FII, 1 to group FI. Eleven R factors were fi-: 5 belonged to group M, of the others 6 (all controlling the cloramphenicol-resistance) 1 was recognized of group K, 1 was incompatible with standard plasmids of both groups S and W, and 4 belonged to group S.
