Morgellon's Disease....not heard of it? You will. You will.

DNA transmission capabilities of Agrobacterium have been extensively exploited by biotechnologists as a means for inserting foreign genes into plants. They discovered the gene transfer mechanism between Agrobacterium and plants, and developed methods to alter Agrobacterium into an efficient delivery system for gene engineering in plants. This is done by cloning the desired gene sequence into the transfer DNA (T-DNA) that will be inserted into the host DNA. Under laboratory conditions the T-DNA has also been transferred to human cells, demonstrating the diversity of insertion application. The mechanism through which Agrobacterium inserts materials into the host cell is very similar to mechanisms used by pathogens to insert materials (usually proteins) into human cells.
