"'Campylobacter jejuni' is a Gram-negative microaerophilic bacterium that is widely believed to be the number one cause of food borne gastroenteritis and diarrhea caused by bacteria. The ability to form biofilms may provide protection from oxygen by increasing the expression of genes responsible for oxidative stress protection. The genes that were tested were the ' Alkyl Hydroperoxide Reductase C (ahpC), Ferrodoxin (fdxA), Catalyse (katA) ', and 'Super Oxide Dismutase (sodB) genes, 16S rRNA' and 'Gyrase (gyrA) genes'. When 'C. jejuni' planktonic and biofilms cells were tested in microaerobic conditions there was no statistically significant differences in the expression of ' ahpC (p=0.139), katA (p=0.065), or sodB (p=0.136)'.
