Horizontal transfer of Shiga toxin and antibiotic resistance genes among Escherichia coli strains in house fly (Diptera: Muscidae) gut.

Abstract excerpt

Whether the house fly, Musca domestica L., gut is a permissive environment for horizontal transfer of antibiotic resistance and virulence genes between strains of Escherichia coli is not known. House flies were immobilized and force fed suspensions of defined, donor strains of E. coli containing chloramphenicol resistance genes on a plasmid, or lysogenic, bacteriophage-born Shiga toxin gene stx1 (bacteriophage...
