Occurrence and reservoirs of antibiotic resistance genes in the environment
N. Seveno,D. Kallifidas,Kornelia Smalla,J. D. van Elsas,Jean-Marc Collard,Amalia D. Karagouni,Elizabeth M. H. Wellington +6 more
TL;DR: There is clear evidence that the self-resistance genes found within antibiotic gene clusters of the producers have transferred to other non-producing bacteria, and there is increasing evidence that selection for resistant phenotypes is occurring in natural environments.

Natural transformation and availability of transforming DNA to Acinetobacter calcoaceticus in soil microcosms.
TL;DR: The results suggest that chromosomal DNA released into soil rapidly becomes unavailable for transformation of A. calcoaceticus, and strain BD413 quickly loses the ability to receive, stabilize, and/or express exogenous DNA after introduction into soil.

Effects of compost addition and simulated solarisation on the fate of Ralstonia solanacearum biovar 2 and indigenous bacteria in soil.
J. Schönfeld,Antonio Gelsomino,L.S. van Overbeek,A. Gorissen,Kornelia Smalla,J. D. van Elsas +5 more
TL;DR: The addition of household compost resulted in enhanced R. solanacearum population decline rates, as well as reduced numbers of diseased plants in suppressiveness tests, and compost amendment clearly induced changes in these communities, which were detectable until the end of the experiment.
151
Specific and Sensitive Detection of Ralstonia solanacearum in Soil on the Basis of PCR Amplification of fliC Fragments
TL;DR: A specific and sensitive PCR detection method that uses primers targeting the gene coding for the flagella subunit, fliC, was established and was applied to detect R. solanacearum in soil.

Migratory Response of Soil Bacteria to Lyophyllum sp. Strain Karsten in Soil Microcosms
J.A. Warmink,J. D. van Elsas +1 more
TL;DR: Migration proficiency showed a one-sided correlation with the presence of the hrcR gene, used as a marker for the type III secretion system (TTSS), as all single-strain migrators were equipped with this system and most non-single-strains migrator were not.
