Abstract
Eleven strains of Campylobacter from earlier fluorescent-antibody studies were examined by DNA hybridization to determine their species. Three of the strains hydrolyzed sodium hippurate, and eight did not. Four of the hippurate-negative strains were in Campylobacter jejuni serogroups, and the remaining strains were in both C. jejuni and Campylobacter coli serogroups. DNA relatedness to type strains of C. jejuni and C. coli indicated that all three of the hippurate-positive strains and two of the hippurate-negative strains were C. jejuni. The six remaining hippurate-negative strains were C. coli. Two of the hippurate-negative strains in C. jejuni serogroups were C. jejuni, and two were C. coli. Three of the strains in serogroups of both species were C. jejuni, and four were C. coli. These studies confirm that a few strains of C. jejuni are hippurate negative and show that identical or highly related antigens are found in C. coli and C. jejuni.
