Recent advances in gene therapy can be attributed to improvements of gene delivery vectors. New viral and nonviral transport vehicles that considerably increase the efficiency of transfection have been prepared. However, these vectors still have many disadvantages that are difficult to overcome, thus, a new approach is needed. The approach of bacterial delivery could in the future be important for gene therapy applications. In this article we try to summarize the most important modifications that are used for the preparation of applied strains, difficulties that are related with bacterial gene delivery and the current use of bactofection in animal experiments and clinical trials. Important differences to the alternative gene therapy (AGT) are discussed. AGT resembles bacteria-mediated protein delivery, as the therapeutical proteins are produced not by host cells but by the bacteria in situ and the expression can be regulated exogenously. Although the procedure of bacterial gene delivery is far from being definitely solved, bactofection remains a promising technique for transfection in human gene therapy.
