Serological detection of Pseudomonas syringae pathovars
In England, a serological method based on a slide agglutination test has been developed for Pseudomonas syringae pathovars (e.g. pv. phaseolicola and pv. pisi [EPPO A2 organism]) and other plant pathogenic bacteria.
The test uses polyclonal antisera conjugated to protein A-rich whole-cell Staphylococcus aureus and is reported to be fast, simple and able to identify organisms directly from infected plant tissue.
