Levantamento da ocorrência de Xylella fastidiosa em cafeeiro do Distrito Federal e entorno

Abstract

A survey of the occurrence of Xylella fastidiosa in coffee (Coffea arabica) plants was performed in Distrito Federal and Vicinity properties. Branches of coffee plants "Catuaí" and "Mundo Novo" were collected from five properties and analysed. Bacterial mass was observed by optical microscopy in the xylem contents. Isolation was performed in BCYE medium and identification was carried out by serological reaction with X. fastidiosa specific antigen. Xylella fastidiosa was detected in samples from all the properties. In 95% of the samples collected, the presence of the bacterium was detected in the xylem contents. This is the first report of the occurrence of X. fastidiosa in coffee plants in Distrito Federal and Vicinity.
