Seasonal variation of Ralstonia solanocearum biovar 2 populations in a Spanish river: Recovery of stressed cells at low temperatures

Article Abstract:

The effects of temperature variation on the population and culturability of Ralstonia solanacearum biovar 2 cells on solid media and their survival at low temperatures were determined. Two liquid selective media for enrichment were used and compared them by using spiked river water samples in order to monitor the pathogen's abundance in water.

Survival strategy of Erwinia amylovora against copper: Induction of the viable-but-nonculturable stable

Article Abstract:

The main aim of the study is to determine whether copper kills or induces the viable-but-nonculturable (VBNC) state of Erwinia amylovora cells and if such VBNC cells retain their pathogenicity. The results have shown the induction of the VBNC state in E. amylovora as a survival strategy against copper.

Influence of native microbiota on survival of Ralstonia solanacearum phylotype II in river water microcosms

Article Abstract:

The fate of solanacearum phylotype II biovar 2 inoculated in water microcosms from a Spanish river is discussed. The studies have shown the affect of different fractions of water microorganisms on the survival of Ralstonia solanacearum phylotype II released into river water microcosms.
