Abstract
Different bacterial strains were recorded as onion rot pathogens. The candidate strains in one region may differ from the other and it may be only one pathogen responsible of the infection in an area or a combination from different pathogens. The present research aimed at detection of the main bacterial pathogen (s) causing onion rot in Egypt throughout storage. Five bacterial pathogens were detected with different occurrence percentage; Erwinia carotovora subspecies carotovora (48.14 %), Erwinia cacticida (18.51 %), Erwinia carotovora subspecies atroseptica (14.81 %), Burkholderia cepacia (14.81 %) and Pantoea sp. (3.7 %).
