The bacteria that cause a common food-borne illness show low
drug resistance in Australia, unlike similar strains from the United States and

facto ban on certain antibiotics in poultry(家禽) and other livestock helps
explain why.
In the study, researchers analyzed samples of
Campylobacter jejuni(空肠弯曲杆菌) bacteria from 585 patients in five Australian
states.
