Wicked new discovery!

Under the microscope again, and looking at isolated bacterial colonies from second generation cultures, found something really weird.
It is a "worm-like" thing, about twice the size of a sperm cell. This thing moves in a way I have never encountered. It exists among the millions of bacillium and rod-type bacteria from the sample. It is very sparse [I have to look for a while to find them] It expands length-wise like an earth worm, then it contracts in-ward from the sides of the middle section to a skinny thread, meanwhile the ends expand really fat. It also looks like it flattens then vibrates. Sometimes the middle flattens and vibrates, and other times it is the ends that do this.
I have all this recorded on video.
Is this a worm which evolved from bacteria!? If this is the case, it changes my whole veiw about acquiring parasites.
These things look similiar to photos taken of "blood parasites" often seen under darkfield microscopes. Shroom
