OBJECTIVE The aim of the study was to develop a microarray-based method for the detection of antibiotic-resistant Campylobacter in broiler farms to decrease the risk of contamination of chicken meat. RESULTS A combination of DNA microarray and primer extension for rapid and simultaneous detection of fluoroquinolone- and macrolide-resistant Campylobacter jejuni/Campylobacter coli, termed Campylobacter Express Resistance Array (CAMERA), was used to analyse chicken caecal droppings. CAMERA assays could detect at least 105 colony forming units of C. jejuni/C. coli g-1 of chicken caecal contents spiked with C. jejuni/C. coli. To compare the CAMERA method and direct culturing method for screening antibiotic-resistant C. jejuni/C. coli in poultry farms, chicken caecal droppings obtained from 42 poultry houses were analysed using both methods. In total, 95.2% of the results (40/42 poultry houses) obtained using the CAMERA and culturing method were identical. In the remaining two poultry houses, the CAMERA could detect the prevalent strain of C. jejuni/C. coli based on results of the culturing method. CONCLUSIONS The culturing method required >3 days to isolate and identify antibiotic-resistant C. jejuni/C. coli. In contrast, the CAMERA required only 6 h. CONCLUSIONS This method can facilitate quick screening and control of fluoroquinolone- and macrolide-resistant C. jejuni/C. coli in broiler farms.
