| Abstract: | Three groups of neonatal calves were inoculated orally with pathogenic strains of Campylobacter jejuni or C coli. The calves developed a mild, self-limiting enteritis characterized by thick mucoid feces. Bacteremia and fecal shedding of Campylobacter were sporadic in all inoculated calves. Two groups of calves were killed 1 to 3 weeks after inoculation to study the pathogenesis of infection. Postmortem culture of tissues revealed C jejuni or C coli most frequently in the ileum, cecum, colon, and blood. Clinical or pathologic differences between C jejuni-inoculated and C coli-inoculated calves were minimal. |
