Campylobacter fetus SSp jejuni

Abstract
Within 7 mo. C. fetus ssp. jejuni was isolated in East Tennessee [USA] from 18 patients with gastroenteritis; 83% of these patients had bloody diarrhea. Absence of other enteric organisms such as Salmonella, Shigella and Yersinia implicated C. fetus ssp. jejuni as the causative agent. A 4-fold increase in titer by tube agglutination from 4 of 8 patients studied supported the pathogenicity of this organism. Treatment with erythromcyin alleviated gastroenteritis symptoms within 24-48 h, with concurrent disappearance of the organism from the feces. An isolation rate of 8% in the patients indicates that C. fetus ssp. jejuni is more common as a cause of human diarrhea than Salmonella or Shigella. The severity of the C. fetus ssp. jejuni gastroenteritis poses a possible reclassification from diarrhea or gastroenteritis to acute dysentery syndrome.
