Case Series Study of Traveler's Diarrhea in U.S. Military Personnel at Incirlik Air Base, Turkey

Military personnel with traveler's diarrhea (n = 202) while deployed to Incirlik Air Base, Turkey, from June to September 2002 were evaluated for pathogen-specific immune responses. Serologic and fecal immunoglobulin A (IgA) titers to enterotoxigenic Escherichia coli antigens (CS6, CS3, and LT) were quite low. In contrast, subjects with Campylobacter infections had high serologic and fecal IgA responses.
