DNA relatedness and biochemical features of Campylobacter spp. isolated in central and South Australia.
Investigations of the etiology of diarrhea in patients in South Australia and the Northern Territory showed that Campylobacter spp. other than Campylobacter jejuni and C. coli were common in children. Campylobacters which were hippurate positive, nitrate negative, and susceptible to cephalothin and polymyxins were shown to be closely related to C. jejuni by DNA studies. Thermotolerant catalase-negative campylobacters were also isolated. These were H2S negative and biochemically resembled the catalase-negative or weak strains found in dogs in Sweden. DNA studies showed these campylobacters to be distinct from C. sputorum subsp. sputorum and to form a homogeneous group distinct from the enteropathogenic catalase-positive campylobacters. Preliminary studies suggest that these campylobacters are related to the Swedish catalase-negative or weak strains.
