Campylobacter enteritis in Denver.

To determine the relative importance of Campylobacter jejuni as a cause of diarrheal illness in patients coming to three hospitals in Denver, we cultured stool specimens from 2,670 patients over a two-year period. C jejuni was identified in the feces of 124 patients (4.6 percent), Salmonella from 90 (3.4 percent) and Shigella from 77 (2.9 percent). Most Campylobacter isolates were obtained in the summer months and from patients 10 to 29 years old. The illness usually lasted less than two weeks; predominant symptoms were diarrhea (98 percent), abdominal pain (88 percent) and fever (82 percent); patients with severe illness frequently had objective evidence of nonspecific colitis. Occult blood and leukocytes were present in stool specimens of 71 percent and 85 percent, respectively, of the patients tested. The duration and severity of illness led to antibiotic therapy in about half of the patients; erythromycin appeared effective. This study confirms the importance of C jejuni as a cause of enteritis; this microorganism should be sought routinely in fecal specimens from patients with diarrhea.
