This study aimed to evaluate the possibility of DNA sequences from genetically modified plants to persist in the gastrointestinal (GI) tract. PCR analysis and transformation assays were used to study DNA persistence and integrity in various ex vivo and in vivo systems using gnotobiotic rats. DNA studied was either plasmid DNA, naked plant DNA or plant DNA(More)
In a study of occupational exposure to Bacillus thuringiensis, 20 exposed greenhouse workers were examined for Bacillus cereus-like bacteria in fecal samples and on biomonitoring filters. Bacteria with the following characteristics were isolated from eight individuals: intracellular crystalline inclusions characteristic of B. thuringiensis, genes for and(More)
Optimal conditions and a standardized method for conjugation between two model lactococcal strains, Lactococcus lactis SH4174 (pAMbeta1-containing, erythromycin resistant donor) and L. lactis Bu2-60 (plasmid-free, erythromycin sensitive recipient), were developed and tested in a inter-laboratory experiments involving five laboratories from different(More)
OBJECTIVES Since the discovery of the insecticidal activity of Bacillus thuringiensis at the beginning of the twentieth century, this bacterium has been used increasingly against various insect pests. In spite of the extensive use of B. thuringiensis, only sporadic clinical case reports have been published. In recent years, the close relationship between B.(More)
BACKGROUND An important concern revealed in the public discussion of the use of genetically modified (GM) plants for human consumption, is the potential transfer of DNA from these plants to bacteria present in the gastrointestinal tract. Especially, there is a concern that antibiotic resistance genes used for the construction of GM plants end up in(More)
