Abstract
This study aims to assess the diversity of campylobacteria (Campylobacter and Arcobacter) in human fecal samples from patients with diarrhea (n = 140) and asymptomatic controls (n = 116) in Chile, using a combination of traditional culture and molecular methods. The culture methods detected campylobacteria in 10.7% of the patients with diarrhea and in 1.7% of the controls. In contrast, the molecular methods detected campylobacteria more often than the traditional culture, with a prevalence of 25.7% and 5.2%, respectively. The traditional methods only recovered the species Campylobacter jejuni, Campylobacter coli, and Arcobacter butzleri, whereas the molecular methods additionally detected the emergent species Campylobacter concisus and Campylobacter ureolyticus.
