The objective of this study was to investigate the horizontal transmission of Campylobacter jejuni and C. coli on free-range broiler farms located in New South Wales, Australia. Fresh faecal/caecal and environmental samples were selected from broiler flocks and enriched for the presence of Campylobacter using ISO 10272:2006 method. The presence of Campylobacter varied among broiler farms and poultry age. Campylobacter jejuni and/or C. coli were detected in the environment from inside and/or outside the shed prior to placement of day old broiler chicks in two flocks. Whereas, Campylobacter was not detected in any broiler flocks within the first two weeks of rearing. The PCR-High-Resolution Melt (HRM)method was used to amplify the flaA gene of Campylobacter spp. The authors found that the same C. jejuni strain was identified in broiler flocks and the environment of the same broiler farm. The same C. coli strain identified from the environment prior to chick placement was consistent in the same broiler flocks. These findings confirm that C. coli and C. jejuni from the environment play an important role of Campylobacter transmission in broiler flocks. Further study, a larger scale epidemiological study would warrant the transmission of Campylobacter spp. among Australian poultry farms.
