> Junctional Space 
The area of space that lies between cells of a tissue, such as the intestine. It is composed of the tight junction, which provides a barrier that prevents the loss of fluid from the blood side of the intestine to the lumen side. Several toxins, such as the ZOT toxin produced by Vibrio cholerae, cause diarrhea by disrupting the ability to seal the junctional space associated with the cells of the intestines.


> Juvenile Gastroenteritis
A term used to describe gastroenteritis in infants. Campylobacter jejuni has been found to cause many cases of juvenile gastroenteritis. In fact, this bacterium may be a more important cause of juvenile gastroenteritis than Salmonella species.
