Studies on Plant Pathogenic Bacteria. II. Serology

Abstract

Fifteen species of plant pathogenic bacteria were used for the production of high-titre antisera. The serological relationships were determined for plant pathogenic and other bacteria belonging to the genera Agrobacterium, Oorynebacterium, Erwinia, Pseudomonas, and Xanthomonas by slide and tube agglutinations and agglutinin-absorption tests. a and fJ antigens were not important in masking "0" antigens but other factors were found to interfere with some agglutinations.
