[F1 ANNEX II U.K. TEST SCHEME FOR DIAGNOSIS, DETECTION AND IDENTIFICATION OF RALSTONIA SOLANACEARUM (SMITH) YABUUCHI ET AL.

Textual Amendments

F1 Substituted by Commission Directive 2006/63/CE of 14 July 2006 amending Annexes II to VII to Council Directive 98/57/EC on the control of Ralstonia solanacearum (Smith) Yabuuchi et al..

Appendix 3

A. Commercially available standardised control material U.K.

(a) Bacterial isolates U.K.

The following bacterial isolates are recommended for use as standard reference material either as positive controls (Table 1) or during optimisation of tests to avoid cross-reactions (Table 2). All strains are commercially available from:

1.

National Collection of Plant Pathogenic Bacteria (NCPPB), Central Science Laboratory, York, UK

2.

Culture Collection of the Plant Protection Service (PD), Wageningen, the Netherlands.

3.

Collection Française de Bactéries Phytopathogènes (CFBP), INRA Station Phytobactériologie, Angers, France.

(b) Commercially available standardised control material U.K.

The following standard control material is available from the NCPPB culture collection.

Freeze dried pellet of potato extract from 200 healthy potato tubers as negative control for all tests.

Freeze dried pellet of potato extract from 200 healthy potato tubers containing 10 ³ to 10 ⁴ and 10 ⁴ to 10 ⁶ cells R. solanacearum biovar 2 (strain NCPPB 4156 = PD 2762 = CFBP 3857) as positive controls for serological and PCR tests. Since cell viability is affected during freeze-drying, these are not suitable as standard controls for isolation or bioassay tests.

Formalin-fixed suspensions of R. solanacearum biovar 2 (strain NCPPB 4156 = PD 2762 = CFBP 3857) at 10 ⁶ cells per ml as positive controls for serological tests.]
