Researchers conducted a study to estimate trends in the incidence of Campylobacter infection in the United States over time. Data on laboratory-confirmed Campylobacter diagnoses at 10 sites were collected from the Foodborne Diseases Active Surveillance Network between 1996 and 2019. Data on antimicrobial susceptibility were collected from the National Antimicrobial Resistance Monitoring System from 2005 to 2018. Campylobacter jejuni and C coli isolates were tested for antimicrobial susceptibility via broth microdilution. The incidence of Campylobacter infection was estimated after adjustments for sex, age, and the use of culture-independent diagnostic testing.
The researchers used a pooled chi-squared statistic to compare changes (2005-2016 vs 2017-2018) in the percentage of ciprofloxacin-, erythromycin-, and extensively drug-resistant isolates. They also used multivariable logistic regression to assess the association between AMR and clinical outcomes.
