Abstract
Bacterial biocontrol agents (BCAs) open up the possibility of controlling plant pathogens in an environmentally friendly way. Although they are naturally occurring microbes, some of them can cause diseases in humans. For successful registration it is necessary to test potentially adverse effects on the human health of at-risk candidates. Existing pathogenicity assays are cost-intensive, time-consuming and furthermore they are often inappropriate for facultative pathogens. We developed a new, fast and inexpensive bioassay on the basis of the nematode Caenorhabditis elegans, which is a well-accepted model organism to study bacterial pathogenicity. A selection of eight strains from clinical and environmental origin as well as potential and commercial BCAs from the genera Bacillus, Pseudomonas, Serratia and Stenotrophomonas were screened for their potential to kill the nematode in an in vitro agar plate …
