| 英文摘要 | Bacillus and related genera comprise opportunist and pathogen species that can threaten the health of a crew in confined stations required for long-term missions. in this study, 43 bacilli from confined environments, that is, the antarctic concordia station and the international space station, were characterized in terms of virulence and plasmid exchange potentials. no specific virulence feature, such as the production of toxins or unusual antibiotic resistance, was detected. most of the strains exhibited small or large plasmids, or both, some of which were related to the replicons of the bacillus anthracis pxo1 and pxo2 virulence elements. one conjugative element, the capacity to mobilize and retromobilize small plasmids, was detected in a bacillus cereus sensu lato isolate. six out of 25 tested strains acquired foreign dna by conjugation. extremophilic bacteria were identified and exhibited the ability to grow at high ph and salt concentrations or at low temperatures. finally, the clonal dispersion of an opportunist isolate was demonstrated in the concordia station. taken together, these results suggest that the virulence potential of the bacillus isolates in confined environments tends to be low but genetic transfers could contribute to its capacity to spread. |
