摘要: The nature of major antigens Pseudomonas syringae was studied on one strain four pathovars (pvs aptata, mors-prunorum, phaseolicola and tabaci) belonging to separate serogroups. Bacterial were prepared by 4 procedures: extraction phenol-water (PW), citrate-NaCl (CN), trichloracetic acid (TCA), precipitation a glycoproteic extracellular complex (GP). 3-Deoxy-2-octulosonic (KDO) revelation in all the extracts showed that procedures led containing similar amounts lipopolysaccharide (LPS). Twenty polyclonal antisera raised rabbits against whole bacteria different extracts. Serological reactions tested gel double diffusion (DD) indirect immunofluorescent staining (IF). The anti-whole cell sera shown contain mostly anti-LPS antibodies. For each pathovar, used as DD gave bands identical given LPS (PW, CN or TCA), heated (HB), sidechain preparations. GP extract itself be rich LPS. To serotype P. syringae, it is advised raise either extracts; whereas reacting for would bacteria.
