Numerous bacteria have been isolated from within plants, and many reported from xylem, but only three species of xylem-limited bacteria (XLB) that are fastidious in cultural requirements, are plant pathogens, and exclusively occupy xylem, have been well characterized. Basal media are basically simple media that supports most non-fastidious bacteria. HOT-376. The information of insect vectors of phytopathogenic fastidious Even so, some types of phytopathogenic bacteria, e.g., fastidious phloem- or xylem-inhabiting bacteria, which for several years were thought to be rickettsia-like organisms (RLO), were only discovered in 1972; more of them, e.g., Serratia, Sphimgomonas, Candidatus liberatus, and the papaya bunchy top bacterium, are still being discovered as plant … cifer-inhabiting rickettsia associated with papaya bunchy top disease has not been cultured (5,8).

Several examples of commonly used bacteriological media, as well as examples with one or more types of bacteria cultured on them are shown below. Division: Firmicutes - Gram-positive bacteria. Pathogens from the fastidious, phloem-restricted 'Candidatus Liberibacter' species cause the devastating Huanglongbing (HLB) disease in citrus worldwide and cause diseases on many solanaceous crops and plants in the Apiaceae family. The bacterial diversity associated with citrus leaf midribs was characterized for citrus groves that contained the Huanglongbing (HLB) pathogen, which has yet to be cultivated in vitro.
