Abstract
Chromosomal DNA of 27 strains ofCampylobacter fetus was analyzed by Southern blotting with a probe of the conserved region ofsapA. The probe hybridized with 23 strains that produced type A lipopolysaccharide. These strains had more than sixsapA homologs. In Southern blots ofSalI-digested chromosomal DNA separated by pulsed-field gel electrophoresis, one fragment from 19 strains and two fragments from 4 strains hybridized. These data indicate that multiplesapA homologs are localized to a limited region on the chromosomal DNA ofC. fetus and thus suggest the possibility of developing a typing system using this method.
