Campylobacter jejuni?

Compare and contrast Campylobacter jejuni and Helicobacter pylori. In your comparison include morphology, disease, reservoir, method of transmission, and treatment.

Campylobacter jejuni is a species of curved, rod-shaped, gram negative bacteria commonly found in animal feces. It is one of the most common causes of human diarrhea in the world. Food poisoning caused by Campylobacter species can be severely debilitating but is rarely life-threatening. It has been linked with subsequent development of the neurodegenerative disease Guillain-Barr茅 syndrome (GBS), which usually develops two to three weeks after the initial illness.

C. jejuni is commonly associated with chickens and has been found in wombat and kangaroo feces, being a cause of bushwalkers' diarrhea. It also naturally colonises many bird species. Contaminated drinking water and unpasteurized milk provide an efficient means for distribution. Contaminated food is a major source of isolated infections, with incorrectly prepared meat and poultry normally the source of the bacteria.

Helicobacter pylori is a helical shaped Gram-negative bacterium that infects various areas of the stomach and duodenum. Many cases of peptic ulcers, gastritis, duodenitis, and perhaps cancer are caused by H. pylori infection. However, many who are infected do not show any symptoms of disease. Helicobacter spp. are the only known microorganisms that can thrive in the highly acidic environment of the stomach. Its helical shape (from which the genus name is derived) is thought to have evolved to penetrate and favor its motility in the mucus gel layer.
