Fifty Erwinia herbicola isolates obtained from host plants were examined in an agglutination reaction with antiserum prepared against E. ananas (E. herbicola) strain CCM 2407 antigen of plant origin and with antiserum prepared against Enterobacter agglomerans strain CNCTC M 269 antigen of human origin. In tests with strain CCM 2407 antiserum, 56% isolates showed a positive reaction, while in tests with strain CNCTC M 269 antiserum only 14% isolates showed a positive reaction. Among E. herbicola isolates which showed a positive reaction with CCM 2407 antiserum 18% showed a positive reaction with the CNCTC M 269 antiserum too. Our results confirmed the serological heterogeneity of E. herbicola population. In spite of the difference in the origin of the two antigens used for the preparation of antisera (plant, human; Japan, Czech Republic) our results indicate that some of our E. herbicola strains and E. agglomerans strain CNCTC M 269 are serologically identical.

UI	MeSH Term	Description	Entries
D007106	Immune Sera	Serum that contains antibodies. It is obtained from an animal that has been immunized either by ANTIGEN injection or infection with microorganisms containing the antigen.	Antisera,Immune Serums,Sera, Immune,Serums, Immune
D010944	Plants	Multicellular, eukaryotic life forms of kingdom Plantae. Plants acquired chloroplasts by direct endosymbiosis of CYANOBACTERIA. They are characterized by a mainly photosynthetic mode of nutrition; essentially unlimited growth at localized regions of cell divisions (MERISTEMS); cellulose within cells providing rigidity; the absence of organs of locomotion; absence of nervous and sensory systems; and an alternation of haploid and diploid generations. It is a non-taxonomical term most often referring to LAND PLANTS. In broad sense it includes RHODOPHYTA and GLAUCOPHYTA along with VIRIDIPLANTAE.	Plant
D004754	Enterobacter	Gram-negative gas-producing rods found in feces of humans and other animals, sewage, soil, water, and dairy products.
D004885	Erwinia	A genus of gram-negative, facultatively anaerobic, rod-shaped bacteria whose organisms are associated with plants as pathogens, saprophytes, or as constituents of the epiphytic flora.
