Experience with the microbiologic diagnosis of Campylobacter enteritis in an office laboratory.

Abstract

Campylobacter jejuni has been recognized as a frequent cause of bacterial diarrhea in infants and children. C. jejuni is a fastidious, Gram-negative, comma-shaped or sea gull-shaped, curved rod which is capable, particularly during the summer months, of causing slimy mucoid, blood diarrhea, abdominal pain and fever. In our pediatric office laboratory we found over a 12-month period that 14 (10%) of 126 stool specimens contained this pathogen. All but two children were diagnosed during the late spring and summer. There was no common source for Campylobacter infections in the patients. In 8 (66%) of 12 patients, C. jejuni infection was immediately detected by examining a 1% aqueous basic fuchsin-stained stool smear. Uncontrolled observations from this study suggest that erythromycin therapy, if started within 2 to 3 days of the onset of illness, is clinically effective.
