Résumé

In 2003, the presence of a rhabdovirus was confirmed in Slovenia using electron microscopy on tomato plants cv. Belle, showing unusual symptoms of distinct chlorotic spots, wrinkles on fruits and narrow, necrotic leaves. In June 2004, the presence of a rhabdovirus was confirmed in potato plants of cvs.

Bistra, Desiree, Discovery, KIS94-1/5-14 and Pata. Plants, growing in the experimental filed for comparative trials were showing unusual virus-like symptoms. Infected plants showed severe dwarfing, leaf curling, reduced leaf size, tubers were small and few in number.

Electron microscopy of negatively stained crude sap extracts revealed rhabdovirus-like particles.

EMDV infection was confirmed by DAS-ELISA on potato, tomato, symptomatic Nicotiana rustica infected with potato sap and symptomatic Nicotiana tabacum cv. White Burley infected with tomato sap. Infected plants were destroyed to prevent risk of the spread of the Eggplant mottled dwarf virus in the territory of Slovenia and the other countries.
