4.Basic information about Erwinia amylovora
Scientific name. Erwiniaamylovora (Burril,1883)Winslowetal.,1920
Transmission routes. infected plant propagation materials (including seedlings, rootstocks and scions), insects, wind, rain, and contaminated packaging materials and transportation
Various natural factors and man-made factors such as transportation tools can cause the spread of pear fire blight. Among them, the infected plant propagation material is pear fire blight
The main route of long-distance transmission.
See Appendix A for additional information on Erwinia amylovora.
5 Method Principles
Immunological detection based on the specific reaction between E. amylovora and antibodies; based on the specific DNA sequence of E. amylovora
Carry out molecular biology testing; conduct testing of pathogenic bacteria based on their culture traits, biological characteristics, host range and harmful symptoms, etc.
Isolation, culture, identification and pathogenicity determination.
