Annually, Campylobacter spp. are responsible for the greatest number of foodborne gastrointestinal bacterial infections in the developed world (1, 2). However, Campylobacter spp. are nutritionally fastidious organisms requiring a microaerobic environment for survival (3). It remains uncertain by what mechanisms Campylobacter survives within multiple hostile environments in sufficient numbers to cause such significant amounts of human disease.

Campylobacter jejuni strain RM3194 was isolated from a clinical sample in 1994 from a human enteritis case at the Red Cross War Memorial Children’s Hospital in Cape Town, South Africa, and was supplied to our laboratory by Robert Mandrell (ARS, Albany, CA) (4, 5). In our research, RM3194 demonstrated an increased resistance to both UV (254 nm) and blue light (405 nm) (6). This resistance produced several-log-greater survival after challenge with UVlight compared to the survival of other C. jejuni strains in our collection.
