  • Shipment of strains to the Vegetable Health Laboratories of the Autonomous Communities
  • Introduction to the collection of strains from other collections
  • Supply of strains that serve as a reference in projects of different national research laboratories and of the Plant Health Services of the Autonomous Communities, to be used in research and in validation of detection methods, in accreditation protocols and in different scientific publications


Key words:
Detección, diagnóstico, epidemiología y gestión de enfermedades bacterianas.

The IVIA collection has been supplying strains to the diagnostic laboratories of the different Autonomous Communities since its creation, as well as to different Spanish and foreign research laboratories.

Phytopathogenic bacteria are a limiting factor in many horticultural and woody crops in Spain, with some bacterial species being considered quarantine organisms in the EU (Directive 2000/29/EC) and being responsible for significant economic losses.

The maintenance of the IVIA collection allows us to ensure and expand the support that the institute's bacteriology laboratory has been providing to the Spanish agri-food sector.

Quality Certifications

The IVIA Bacteriology Laboratory has ENAC Accreditation (1165 / LE2283) according to the UNE-EN ISO / IEC 17025 Standard for carrying out tests on agri-food products, and a quality management system

Brief historical review

The collection of phytopathogenic bacteria dates back to the creation of the IVIA Bacteriology Laboratory in 1977. Since 1993 it has been a Reference Laboratory of the Ministry of Agriculture, Fisheries and Food, this has driven the growth of the collection, and it has contributed to the development of this work.
