Abstract

This paper presents the characteristics of Erwinia amylovora strains isolated from Cotoneaster horizontalis and Pyracantha coccinea on the territory of Nis District in Serbia, as well as biochemical and physiological characteristics of these strains. Identification of Erwinia amylovora strains was made according to internationally recognized methods, such as: Biolog test, immunofluorescence, ELISA test and agglutination test, and biochemical and physiological characteristics of the isolates of Erwinia amylovora were determined by levan production, oxidase and catalase activity, hydrolysis of gelatin and esculin, VP - test, MR - test, and glucose metabolism. Characteristics of the isolated strains fully coincide with the control strains which were isolated from pome fruits.
