SUMMARY:Does Helicobacter Pylori Exhibit Corkscrew Motion While Swimming?
DESCRIPTION:Featuring Maira Constantino\n\nPart of the Preliminary Oral Exa
	m.\n\nExamining Committee: Rama Bansil\, Shyamsunder Erramilli\, Kirill Kor
	olev and Kevin Black\n\nAbstract:\n\nHelicobacter pylori is a spiral shaped
	 bacterium associated with ulcers\, gastric cancer\, gastritis among other 
	diseases. In order to colonize the harsh acidic environment of the stomach 
	the bacterium has to go across the gastric mucus layer. Many studies have b
	een conducted on the swimming of H. pylori however none have studied the tr
	ajectory path. We present an experimental study of the swimming trajectory 
	of H. pylori by a quantitative analysis of the bacterium rotation and trans
	lation using phase contrast microscopy and particle tracking techniques. We
	 also measure the bacterium body parameters simultaneously with the traject
	ory\, allowing for the first time to test the validity of theoretical model
	s of the swim of H. pylori. Our measurements show very well defined helical
	 trajectories\, from which we measure the body rotation.\n\n![Maira](/resou
