I need as much info on clampyhlobacter ie. what is it? what does it do? where does it grow? etc

Campylobacter is the name of a Gram-negative bacterium that causes diarrhea in humans. The name means 'curved rod' and that is what it looks like. C. jejuni is the most common member of this family and is frequently found in chickens, and hence on poultry meat (not in eggs). C. coli is another one, found on pork and chicken. Raw (unpasteurized milk) and unclean drinking water are also common sources for this food-poisening bug.

Your Campylobacter specialist, Trudy Wassenaar

Campylobacter are curved gram negative rods. they were not recognized as human pathogens until the 1970's because they are difficult to cultivate. They are microaerophiles (require low oxygen tension) and high incubation temps-42oC, and they need selective media. They cause more foodborne illness than Salmonella and Shigella. It is a major cause of diarrhea. Human infection is usually caused by ingesting contaminated milk or meat. Symptoms include bloody diarrhea, cramps and sometimes fever. It is usually self limiting and non life threatening and lasts less than a week.
