[Transposons coding beta-lactamase with an extended spectrum of effects and resistance to other antibiotics].

The authors present contemporary knowledge concerning the transposition of resistance genes to penicillins, cephalosporins and carbapenems, and transposons and integrins coding resistance to other antibacterial substances. Transposition is, together with bacterial conjugation and transduction with bacteriophages, another mechanism of mobility and restructuring of resistance genes in bacterial strains of the same and also in other bacteria.
