The Value of Serological Tests for the Identification of Pseudomonas malvacearum

Abstract

Because plant inoculations are considered unreliable for the identification of Ps. malvacearum, serological reactions were employed. Antisera were prepared by giving rabbits intravenous injections of a suspension of the culture. Agglutination reactions with this serum and a number of strains of the organism, isolated from different sources, showed the agglutination test to be a simple, highly specific and reliable method for identifying the organism.
