BACKGROUND Ciprofloxacin-resistant Campylobacter jejuni isolates obtained from infected patients in Australia have not been detected in studies of isolates from specific geographic areas. The Australian government has prohibited the use of fluoroquinolone in food-producing animals. To assess the impact of this policy, we have examined the antimicrobial(More)
Campylobacter is a common cause of bacterial gastroenteritis in Australia. Antibiotic resistance among Campylobacter is an emerging problem in Europe and the United States of America. Monitoring may detect emerging resistance. Since there is no epidemiologically validated subtyping system for Campylobacter, antimicrobial resistance patterns may prove useful(More)

BACKGROUND Antimicrobial resistance is a major issue in the Shigellae, particularly as a specific multidrug-resistant (MDR) lineage of Shigella sonnei (lineage III) is becoming globally dominant. Ciprofloxacin is a recommended treatment for Shigella infections. However, ciprofloxacin-resistant S. sonnei are being increasingly isolated in Asia and(More)
