Antimicrobial Use: A Risk Factor or a Protective Factor for Acquiring Campylobacteriosis?

Background. It is well acknowledged that the use of antimicrobial drugs in food animals leads to antimicrobial drug resistance in foodborne bacteria such as Campylobacter; however, the role of human antimicrobial usage is much less investigated. The aim of this study was to quantify the odds of campylobacteriosis conferred by human consumption of fluoroquinolones and macrolides. Methods. We conducted a registry-based retrospective case-control study on 31 669 laboratory-confirmed cases of campylobacteriosis between 1999 and 2005 in Denmark. Data were obtained from several Danish databases: th
