This is all i know about it.........
Although considered structurally simple, bacteria are extremely diverse from a metabolic standpoint and are found almost everywhere on Earth in vast numbers—from living in jet fuel and on the rims of volcanoes to thriving in hydrothermal vents deep on the ocean floor. There are both beneficial and pathogenic bacteria. Beneficial bacteria are involved in such diverse processes as digestion in animals, nitrogen fixation in the roots of certain legumes, the decomposition of animal and plant remains, and sewage disposal systems. Pathogenic bacteria, on the other hand, cause severe and often fatal diseases in humans, animals and plants. The first bacterial disease ever discovered was anthrax (caused by Bacillus anthracis) of cattle and sheep in 1876. The discovery of anthrax in cattle was immediately followed by the discovery of fireblight of pear and apple (caused by Erwinia amylovora) by T. J. Burrill from the University of Illinois (1877–1885). Another group of bacterial pathogens are difficult or impossible to culture in the laboratory and are called fastidious vascular bacteria. They grow in either the xylem or phloem tissues and interfere with the transport of water and nutrients in the plant. Many of them are vectored by sucking insects such as leafhoppers, planthoppers and psyllids. Studies of corn stunt provide evidence that once the insect vectors establish the infective particles in their bodies, the insects retain the ability to transmit them the rest of their lives. Until their discovery in 1967, most of the diseases now known to be caused by fastidious vascular bacteria were believed to be caused by viruses and were initially described by virologists.
