Query: NC_007716:266500 Aster yellows witches'-broom phytoplasma AYWB, complete genome Lineage: Aster yellows witches'-broom phytoplasma; Phytoplasma; Acholeplasmataceae; Acholeplasmatales; Tenericutes; Bacteria General Information: Mycoplasma-like plant pathogen. Aster yellows witches'-broom phytoplasma belongs to a group of mycoplasma-like organisms that infect plants and insects. Phytoplasmas are insect-transmitted plant pathogens that cause economically important diseases in many plant species, including vegetables, ornamentals, and fruit crops. Aster yellows is a sporadic disease of vegetable crops and is transmitted by the aster leafhopper.

General Information: This strain is an isolate from an epidemic that took place in China in the 1950s. Causes dysentery. This genus is named for the Japanese scientist (Shiga) who first discovered these organisms in the 1890s. They are closely related to the Escherichia group, and may be considered the same species. These organisms are human-specific pathogens that are transmitted via contaminated food and water and are the leading causes of endemic bacillary dysentery, causing over 160 million cases of infection and 1 million deaths yearly worldwide. The bacteria infect the epithelial lining of the colon, causing acute inflammation by entering the host cell cytoplasm and spreading intercellularly. are extremely virulent organisms that can cause an active infection after a very low exposure. Both the type III secretion system, which delivers effector molecules into the host cell, and some of the translocated effectors such as the invasion plasmid antigens (Ipas), are encoded on the plasmid. The bacterium produces a surface protein that localizes to one pole of the cell (IcsA) which binds to and promotes actin polymerization, resulting in movement of the bacterium through the cell cytoplasm, and eventually to neighboring cells, which results in inflammatory destruction of the mucosal lining. Shigella boydii is uncommon except in India, where it was first isolated. Progression to clinical dysentery occurs in most patients infected with this organism.
